Amendment No. 5

RFP AG-9A40-S-13-0007

Request for Information

Portillo Concrete, Inc. (PCI)

1. Items No. 31 20 00D and 31 20 00H have unit prices for Aggregate Base material per Cubic Yard. Is it possible to change the unit price to Per Ton since this is the way the material is purchased and will make it much easier for billing purposes? Answer: No Change. Based on the specification, Section 31 20 00-2, estimated quantities for Aggregate Base materials are based on Density of 125 lb/cf. Therefore each CY is estimated to weigh 1.6 tons.

2. Item No. 33 36 00 does not provide location of septic systems. Do both systems lead to a single leach field or have a separate leach fields, and the location of the field or fields?

Answer: See site plan C3, for the location of both leach fields.

3. Is contactor required to have an SSHO and QC on site at all times, can this be the same person? Answer: SSHO and QC do not have to be on site at all times, and yes both positions can be filled by the same person. However if the proposal states a SSHO and or QC will be on site full time then I will require SSHO and or QC to be on site full time.

4. Additive 4 - Photovoltaic System, What size is required? Answer: Additive 4 has been removed from the requirements in amendment #2

5. Additive 5 - Generator System, What size KW Generator is required? Answer: The generator will be sized according to the design requirements. Refer to Section 26 32 10, in the CSI Specifications.

1. Is Civil Engineering Required? Answer: See Statement of Work and Kitchen Creek Helibase Specification 13 34 19.

2. Is the current civil designed shown acceptable and will be complete as shown? Answer:

We don’t understand your question.

3. Is Storm Water permit required? Answer: Yes, see Kitchen Creek Helibase Specification 01 57 24.

4. Spec Section 03 30 00-4 provide concrete mix strength for building floor slab and walkways, but nothing for Helipad. Also no weight design information given for helipad to allow structural calcs for thickness of helipad slab. Answer: Concrete information is found in the Geotechnical Report, which also gives thickness of all concrete (helipad, taxiways, parking, and service roads).

5. Will CAD files of the ALTA survey and preliminary civil engineering drawings be made available to the winning team? Answer: No. ACAD grading plan has been posted on Fed Biz Opps.

6. Will CAD files of the building floor plans and proposed elevations be made available to the winning team? Answer: No.

7. McCloud Office A8.0 and A9.0 are missing. Can we get a copy of those sheets?

Answer: Not needed.

LB Civil Construction

1. Water supply for the foam water fire sprinkler system is anticipated to be as follows per NFPA 16 (not NFPA 409): How will this work in a freezing environment during winter months?? (or will the system be shut off in winter when unoccupied??) Will the foam tank be subject to freezing? Use of freeze resistant foam concentrate needed? Answer:

Freezing weather is a possibility. Designer will have to take that into consideration and design the system accordingly.

2. Flows: NFPA 16-2011 yields 0.16gpm/sf over 5,000sf = ~ say 900-1,000gpm +/- x 30 minutes = 30,000 gallons total. PRESUME the two 20,000 gallon potable water tanks will supply water for this foam water sprinkler system. Answer: You presume correctly.

3. WHERE is 8” piping and the 1,000 gpm fire PUMP going? What about electric power or will it be diesel? Does all of this go into a small prefabricated fire pump building placed over the top of the water storage tanks and use a vertical turbine fire pump? Answer:

There is no 8” piping or 1000 gpm fire pump in the Kitchen Creek Helibase. There is a jet pump and pressure tank located in the corner of the Hangar building. This project is all electric with an option item for an LPG fired generator.

4. The specifications provided for the well drilling and well construction do not match the line items on page 5 of the RFP, so it is unclear as to what sizes are supposed to be used for the various line items. Answer: Clarifications will be made in a future amendment.

5. Neither the specs nor the bid line items for drilling and well construction meet the necessary government standards per the County of San Diego and the State of California. The well cannot be drilled and constructed per the specs and bid line items.

Answer: Since this project is not for a public water system or community water system, we are not obligated to adhere to Title 22 standards.

6. Can we provide OSP Cat6 from Admin to garage directly to horizontal locations or is it required to run 25 pair and install a cabinet in each building. The maximum distance for cat6 cabling is 295ft. I am looking at 180 to 200ft from Admin to garage. Answer: The cables going to both the Hangar and Garage should be 25 pair armored OSP cables. Both cables need to be terminated to a Building Entrance Terminal (BET) with lightning protection. The BET’s should be properly grounded. No cabinet is needed in the Admin Office telecom closet. The BET should be mounted on the wall next to or close to the wall mounted rack but not inside the rack. The BET’s that will be mounted in both the garage and hangar can be placed inside a small cabinet as needed for protective purposes.

7. There is currently no indication on the plans or in the specifications to chlorinate the well water. Will this be required? Answer: No.

1. 001 3/19/13 This RFI is based on the bid line item for an 8-inch diameter water well casing 33 21 13D&E. Based on California Department of Water Resources Well Standards Bulletin 74-90, the following would need to apply to correctly install an 8-inch diameter drinking water well: � Bid item 33 21 13A requires a 16-inch borehole, not 12-inches as listed (to accommodate the required sanitary seal dimensions for a 12-inch conductor casing) Answer : Changed to a 14” hole in Amendment 1

• Bid Item 33 21 13C requires a 12-inch conductor casing, not 10-inches as listed ( to meet the requirement for a 2-inch annular seal between conductor casing and well casing, 2- inches on either side of 8-inch well for a total of 4-inches) Answer: Annular seal is between conductor pipe and 14” dia. hole for 50 feet (seal is NOT between the conductor and casing).

• Bid item 33 21 13D&E requires a 12-inch borehole to 500 feet for correct installation of an 8-inch well. There is no bid line item listed for this. Is this item included in 33 21 13D&E? Answer: We are changing casing to 4 ½” plastic pipe. A 6” hole should be adequate.

• Additionally, if this is a new drinking water system for the base, then the state of California Department of Health Services will require a new water system permit (the permit applies to federal facilities in California). There is no bid item for this. Answer:

The F.S. will obtain the permit once the well is in.

2. 3/20/13 Does this project require equipment that requires 480/277V? Is there any special equipment that requires unusual electrical requirement including voltage, Hz, the installation method, etc.? Answer: No to both questions.

3. 3/21/13 The SDG&E maps are not clear on whether they are existing work or new work.

Are these dashed lined existing work (on Sheets 1 of 5, and 2 of 5)? Please clarify that our project SDG&E service will be extending from Transformer #5 on Sheet 2 of 5, all the way up to Tag #26 the 600A meter panel (on Sheet 5 of 5)? Answer: The trenching will be from T 5 on sheet 2 to transformer 26 on sheet 5. Dashed lines are existing work.

4. 3/21/13 Will the water system be classified as a public water system, requiring approval from DHS? Answer: No.

5. 3/21/13 Will a chlorination system for the water system be required? Answer: No.

6. 3/21/13 Can you provide an estimated maximum daily flow for the water and sewer systems? Answer: The estimated maximum daily flow rate for water use “on site” is 300-350 gpd. However, the water use from the standpipe (hydrant) will be considerably higher. This water will be hauled off-site for wildfire suppression and could be as high as 20,000 gpd. This use will be very intermittent and for short durations of time. The sewer system should be as shown on the drawings, sheet C3. For the office building, there are 3 lines of 15 infiltrators each. For the Hangar, there are 3 lines of 13 infiltrators each. Each system has a 1000 gallon septic tank.

7. 3/21/13 What is the design flow rate for the jet pump shown on plan sheet CP 4?

Answer: The jet pump needs to be sized to provide the above flows. The hydrant needs to have a minimum flow rate of 100 gpm.

8. 3/21/13 A fire hydrant is shown on the site plan. Is the booster pump system shown on plan sheet CP 4 expected to supply sufficient water to supply this hydrant and if so, what flow and pressure is desired? Answer: The primary purpose for the fire hydrant will be for tanker fill for fire suppression off site. Water to the hydrant will come from the pressure tank/jet pump. See answers to questions 006 and 007.

9. 3/22/13 Will the hanger building be used as the maintenance facility to repair the aircrafts? If the repair service is expected in this facility, what kind of equipment or system is required, such as a crane or mono-rail? Answer: Used for storage (security). No requirements for specialized equipment or systems.

10. 3/22/13 Is the lightning system part of the Base Bid or Additive? Answer: The lightning protection system is part of the metal tower and should be included in bid item 13 36 13 – Metal Tower.

Tititlek Construction

1. Please confirm that the finish grade elevations on the grading plans under the FOD Control Rock and Class 3 Riprap sections are dirt elevations and the rock placement is over this finished grade. If the finish grade elevations at these locations are top of finished rock, then the excavation for the site is at least 3,000 CY over the bid item quantity of 18,469 cy. The item is listed as DQ so no additional payment will be made by owner if more dirt must be excavated to accommodate these rock sections. Answer: Finish grade elevation is top of finished rock and that is what our quantities are based on.

2. Bid item 03 30 00C concrete curb, does this bid item cover detail L and detail H curbs as shown on C20 and C21? Answer: Delete detail H on sheet C20. Bid item covers only detail L.

3. Please define the location of detail L curb, it appears this is only placed at the parking area at the office and garage and the driveway to these buildings. If this is the only location then the DQ is off by 7 CY, total is 22 CY. Answer: Detail covers curb at parking area and garage. Quantity is being changed to 19 cy.

4. If detail H curb is not paid under bid item 03 30 00C, where does this curb abutting the taxiway get paid? Please confirm that both sides of both taxiways get this curb detail.

Answer: There is no curb on any taxiway.

5. Geotechnical report for concrete, please clarify the locations of thickened concrete edges.

The entire perimeter of both Helipad aprons? The entire perimeter of all service roads?

Answer: Yes to both questions.

6. Please confirm the two PCC pavement sections; Helipad and Taxiways are 8.5” of unreinforced concrete, and the service roads, driveways and parking areas are 6” of unreinforced concrete. Answer: Geotech report section 7.4.3.2 for unreinforced concrete (8.5”). Section 7.4.3.4 for reinforced concrete (7.5”). Design quantities (DQ) are based on unreinforced concrete.

7. Do the dowel bars for concrete paving require epoxy coating? Answer: See Geotech Report, Section 7.4.3.4

8. Please confirm that all concrete paving is unreinforced and that all joints will require joint / tie bars as described on pages 16 and 17 of the geotechnical report. All longitudinal construction joints will require tie bars and the transverse contraction joints will require dowel bars. Answer: See 7.4.3.2 for unreinforced concrete. 7.4.3.4 is for reinforced concrete. DQ is based on unreinforced concrete.

9. Please provide figure 12-31 joint sealant detail and all specifications for joint seal for the concrete pavement. Confirm that all contraction and construction joints in the pavement require joint seal. Answer: The Geotechnical Site Evaluation Report has been amended. The changes are to provide clarification only, not to change anything.

Clarification of the pavement thicknesses, doweling, and joints was the main emphasis. We have also added links to the report to make it easier to navigate around the report.

1. Underground water tanks. All underground storage tanks, regardless of product contained, require monitoring wells. I quote a little known code section on this subject below: Article 6. Distribution Reservoirs §64585. Design and Construction. (12) For a subsurface reservoir, (E) Provided with a minimum of two groundwater level monitoring wells drilled to a depth at least 20 feet below the reservoir bottom and sited within 100 feet and on opposite sides (up-gradient and down-gradient) of the reservoir; and---.I do not see where the regulatory required monitoring wells are to be placed, nor is there any specification as to the completion details of these wells. Answer: monitoring wells are not required.

2. I do not see source water meters, as required by California Title 22 § 64561, on any of the plan sheets. Where are they to be located? Answer: please see sheet CP4. Water meter is between jet pump and pressure tank.

3. Page CP5, KEY NOTE 1, there is reference to an existing well. I only see one production well on the plans. California Title 22 §64554(c) requires a minimum of two water sources.

Where is the existing well? How is it to be tied into the system? Answer: there is no existing well, nor is one required.

4. Page CP5 Well and Enclosure Detail. I do not see a “discharge to waste” valve as required by California Title 22 §64560(c)(3)(E). These discharge valves are typically located at the well head discharge piping, between the well head discharge and transmission piping, with their own check valve to protect against backflow. Please clarify if discharge valves are required and where they are to be located? Answer: Not required.

5. Page CP5 Well and Enclosure Detail. California Title 22 §64560(c)(3)(E)1 requires “Fittings and electrical connections to enable chlorination facilities to be readily installed;”.

I do not see these on the drawings or specifications? Please clarify if these fittings are required? Answer: No chlorination facilities will be installed. No fittings are required.

6. In the Specifications, section 33 21 13, Paragraph 3.08 a well test is described. The described test does not appear to meet with the minimum specifications in Title 22 §64554(g). Please confirm requirements for the well test? Answer: Well test to be performed as per Kitchen Creek Helibase specification

7. Bid pricing. Lines 33 21 13D and 13E indicated 8” Liner. Specifications 13 21 13 1.06-A-3 and A-4 call out for 6” minimum diameter. Based on the written specifications and well design it is impossible to construct the well with an 8” Liner. I suspect that the 8” is a typo? Please clarify liner size? Answer: Well liner (perforated and non-perforated) will be changed to 4 ½” diameter PVC. Bid item and Specification will be changed to reflect this change.

8. I do not see complete specifications for the “Jet Pump” described on drawing CP4. The power requirements are partially shown, but the pump capacity or volume, and horsepower, are not shown. Please provide specs for jet pump. Answer: Designer will be responsible for determining ultimate size of the pump.

9. Part 1, Sec. 1.06 -A, items 3&4: Calls for a minimum 6" diameter well casing and perforated casing. Bid line items 33 21 13D & 33 21 13E: Calls for 8" solid steel liner and 8" perforated liner. Change 1.06 items 3&4 to 4" minimum diameter well casing.

Change 13D to 4" Liner, Change 13E to 4" perforated liner. Answer: Bid items 33 21 13D & E are being changed to 4 ½” PVC.

1. Part 2, Sec. 2.01, items 2&3: Call for PVC casing and PVC perforated casing. Bid line item 33 21 13D & 33 21 13E: Call for 8" steel. Change 13D to PVC. Change 13E to PVC. Answer: See question 1 above.

2. Bid line item 33 21 13A: Calls for 12" diameter drilling. Answer: changed to 14” in amendment 2.

3. Bid line item 33 21 13C: Calls for 10" conductor casing. Part 3.01, item E calls for bore size 4" larger than casing. Change 13C to 8" diameter conductor casing. Answer: 13C is correct at 10”.

4. Bid item 33 21 13B: Calls for 6" diameter drilling and pilot hole. Part 3.01, item D states

"The bore size of the well shall accommodate both the production casing, conductor casing, sanitary seal and the gravel pack." Change bid item 33 21 13B to 8" diameter drilling and pilot hole. Answer: Bid item will remain at 6”

Anderson Burton Construction, Inc.

1. 2.2 of Applicable Codes, Regulations, & Requirements references Kitchen Creek Helibase § 13 34 19 – Metal Building Systems. This section is not found with the Kitchen Creek Helibase specifications. Should we refer to § 13121 – Metal Building Systems of the Happy Camp Helibase specifications? Answer: Please check your specifications for Kitchen Creek Helibase again. The spec is there.

2. For the Hangar building, can the roof be a flat, sloped roof? Or is a roof with a ridge required? Answer: A roof with a ridge is required.

3. There are several references to the McCloud drawings and specifications. Have these been posted? Answer: Yes, see the solicitation under “sample pdf”. The McCloud drawing and specifications are behind the Happy Camp drawings and specifications. Be sure and scroll to the end.

4. On Drawing C18 (Kitchen Creek Helibase, 19 of 38) there is a detail for a concrete swale.

Should the price for this be included in Site Item 31 20 01I? If not, where should it be included? Answer: include as part of 31 20 00I.

5. L.4(b)1 states that we are to provide a list of references when discussing our past performance. Is this a “stand alone” list or should we list each reference with the respective similar contract? Answer: The list of references could be a “stand alone” however I would also like to see references for the projects listed as “similar.”

6. L.4(b)2 directs us to describe the work that will be self-performed and the work that will be subcontracted. Would this discussion be better placed at L.4(b)3.B. Project Management? Answer: Yes. Correction will follow in the amendment.

7. Will the Forest Service provide the contractor the Word documents for the specifications?

Answer: Yes, Word doc could be made available to the successful offeror.

8. Will the Forest Service provide the contractor copies of all engineering data used to design and size the existing site utilities, electrical, plumbing, water tanks, septic systems, as shown on the drawings? Answer: There are no “existing” utilities at this site. All utilities shown on the drawings are new utilities to be constructed. The plumbing, water tanks, and septic systems have been properly sized by the Forest Service and should be bid accordingly. Some of the electrical has been sized and some remains to be sized by the contractor/designer as per sheets CE1-3.

9. If the Forest Service takes more than 21 days in its review of design submittals, will the contractor be given a like number of additional days for the next design submittal/project completion? Answer: Yes. However, keep in mind that each resubmittal for incomplete or missing data will trigger an additional 21 day review period which will not qualify for additional time.

10. Will FAA permitting and fees be the responsibility of the General Contractor or USDA Forest Service? Answer: No FAA permit is required. This is not a General Aviation heliport. It is a Prior Permission Required (PPR) facility.

11. Plan Sheet C13 shows a 4” SCH 40 PVC pipe going from the Drain Basin and Plug in the containment area and flowing down and dumping into the rip-rap where a 24” cmp washes into. Is it your intent to drain possible contaminated liquid into the soil? Answer:

When the containment is in use (fuel truck is on site), the plug is in. Any trapped contaminant is cleaned up prior to washdown. When the containment area is not in use, the plug is pulled and all rainwater is allowed to drain into the riprap.

12. Plan Sheet C6 shows a DI in the center of each Helipad. But no piping is shown exiting the DI. Then adjacent to the edge of the helipad, there is a light green box with a dotted green line running a short distance out of the box, but it is not connected to anything, it just stops. Is it your intent to connect the Helipad DI to the green box, assuming it’s the Oil-Separator? Again, assuming the green box is the Oil-Separator and the dotted green line coming out is a pipe line full of overflow waste water, where do you propose to direct the finished pipe line? Answer: Sheet C2 shows the location of the oil-separator and leach lines. Drains shall be sized appropriately for the sand-oil separator from the Drop Inlet on the helipad to the oil-separator for each of the 2 helipads.

13. §4 of Applicable Codes, Regulations, & Requirements discusses the design requirements for the project. 4.4.2 presents a design submittal matrix. If the paragraphs preceding the matrix differ from the matrix (e.g., CDs required), then do the paragraphs govern?

Answer: please be more specific where the differences are. I don’t see any differences.

14. Will a design charrette meeting be required prior to the start of design: Answer: not sure what you mean by a “design charrette”. We will have a pre-work meeting prior to start-up of the project.

15. If a design charrette meeting is required, where will it be held? Answer: Again, not sure what a design charrette meeting is but the pre-work meeting will probably be held in the Cleveland N.F. Supervisors Office

16. Confirm that four (4) design submittals (35%, 70%, 95% and 100%) will be required.

Answer: that is correct

17. After the government review period for each design submittal, will a design review meeting be required? Answer: if there are excessive issues with the design, then a meeting could be called. Otherwise, a work order or some such written documentation can be used.

18. If design review meetings are required, where will they be held? Answer: either at the Supervisors Office or, if there is a construction trailer set up, it can be done at the job site.

19. §4 of Applicable Codes, Regulations, & Requirements discusses the design requirements for the project. ¶4.4.2 presents a design submittal matrix. If the paragraphs preceding the matrix differ from the matrix (e.g., CDs required), then do the paragraphs govern?

Answer: please be more specific where the differences are. I don’t see any differences.

20. Will a design charrette meeting be required prior to the start of design. Answer: not sure what you mean by a “design charrette”. We will have a pre-work meeting prior to start-up of the project.

21. If a design charrette meeting is required, where will it be held? Answer: Again, not sure what a design charrette meeting is but the pre-work meeting will probably be held in the Cleveland N.F. Supervisors Office

22. Confirm that four (4) design submittals (35%, 70%, 95% and 100%) will be required.

Answer: that is correct

23. After the government review period for each design submittal, will a design review meeting be required? Answer: if there are excessive issues with the design, then a meeting could be called. Otherwise, a work order or some such written documentation can be used.

24. If design review meetings are required, where will they be held? Answer: either at the Supervisors Office or, if there is a construction trailer set up, it can be done at the job site.

Ponciano Construction Inc.

1. Is the proposed Foreign Object Debris Control Rock supposed to be placed so the top of the section is at proposed finish grades per plan or placed on top of proposed finish grade? Answer: The rock is the finished grade wherever it is placed.

2. What is the proposed thickness of the Foreign Object Debris Control rock? There is not a detail showing the actual required thickness (whether below or above finish grades).

Answer: The quantity in the Schedule of Items is based on a thickness of FOD rock of 6 inches.

3. What is the proposed section of base below the Taxiway? The specs call for minimum of 4” of Aggregate Base to be use with the thickness to be as “SHOWN ON DRAWINGS”.

The cross section for the taxiway (detail H, Sheet C-20) shows a section of base but does not give a thickness. Answer: Class II Aggregate base is 6 inch thickness below the taxiway (and is also 6 inch thickness below the helipad, service roads, parking area and driveway).

4. Please clarify the intent of the helipad. Is the hose reel for firefighting or for refueling?

How is fuel handled on this site? Answer: Hose reel is only for washdown of the helipad. Fuel is handled by tanker truck which will be parked in the containment area.

Ahtna

Drawings:

1. Will the provided drawings be provided to the selected bidder and if so what format are they in (ACAD or Microstation)? Answer: yes, ACAD

2. Set of drawings provided do not include structural and HVAC. Is the intent for the contractor to provide complete design for the missing drawings? Answer: Yes

3. Some of the drawings are not complete or missing references from the specification sections. Will the government re-issue or will the contractor be responsible for completing the design? Answer: The contractor is responsible for providing complete designs for the three buildings, including all drawings and specifications.

Specifications:

4. 33 16 00 – Section 1.04 requires PE sealed structural calculations. Does the Government require CA PE stamp or CA SE (Structural Engineer) stamps or can the person be a certified PE or SE for a state other than CA. Answer: requires California PE or SE.

5. 28 30 00 – Section 01 11 00 indicates the electronic detection and alarm is optional.

Please confirm if detail design is required. Drawings provided indicate basic locations of some of the equipment. Is the contractor responsible for the detail design of this system?

Answer: If the option is selected, the contractor is responsible for the design and installation.

6. Section 26 32 10 – Section 1.2 refers to a LPG generator system but drawings indicate the generator to be sized. Depending on the size required it may not be feasible of using a 120/208V generator. Does the contractor have to use the voltage indicated? Can non-critical loads be removed from the generator to accommodate this requirement and keep the voltage requirements? Answer: Under section 1.1A of specification 26 32 10, only the critical loads are to be provided for.

7. Section 26 31 10 – Section 1.1 refers to the architectural drawings for the proposed roof areas for the PV system. There are no roof details shown in the solicitation package.

Can the government provide additional information for the design intent? Answer:

Drawings are only intended to convey amount of roof area available on the garage and office building for PV system. Roof details will be provided by the contractor when the buildings are designed.

8. Section 21 12 16 – Can the government provide location for the required fire hose reels?

The drawings do not show locations or quantity of the units required. In addition, is a fire pump required? A booster pump is shown but it is not clear if the function is to boost water pressure, or fire protection. Answer: The location is the helipad utility pad, one for each helipad. See drawings C2, CE2, and CE4. There will be two hose reels.

The booster pump shown is to boost water pressure for the entire site. No additional pump is needed for fire protection.

9. Section 03 30 00 – Section 2.1H provides design requirements but structural drawings are not provided. Is the contractor responsible for providing structural drawings?

Answer: Yes.

10. On sheet C14 of the provided plans there is mention of 12” “WEIR” on one of the sections. What is “WEIR”? Answer: The weir shown on drawings C13 and C14 is merely a low spot on the detention pond to allow for overtopping if the pond fills to the top. The weir is 20’ across and 12” lower than the top of the pond.

Robert DeVan – MZTCO

1. As per the schedule of values item 10 51 13 Metal Lockers, were unable to determine the quantity or location of the lockers in the specifications or the contract drawings. Please determine the location and or the quantity of the said lockers. Answer: See amendment 1

2. As shown on the contract drawings for the office building, Sheet A1 notes the use of an uninterruptable power supply and as stated in specification section 27 00 00 – 22 to be in the “ER Room”. Confirm that the UPS system provided on Sheet A1 is correct due to the absence on the electrical drawings. Answer: Yes, it is correct.

3. The deletion of the Insulated Hangar Doors are noted, but please clarify if there is to be insulation of the wall and roof panels for both the Hangar Building and Garage. Answer:

See amendment 2

4. We are concerned about the 320 Calendar Day contract duration stated in the specs. A typical design build project of this size is approximately 540 Calendar days. The main bulk of this duration is consumed by the design investigation (boring logs, survey, geo-technical inspection and evaluation), design development, design development review by the owner, Final Design Development, and Final Design Development Review by the owner. Given the requirements of design submissions and 21 calendar day review time by the owner per each design submission this duration is very aggressive. As a design build contractor it is essential that we turn in at least one round of design submission (to verify final details of each critical item prior to ordering the pre-engineered metal buildings, pumps, valves, fittings, site utilities, storage tanks, etc…) to get owner concurrence on the items being supplied. After approval of design we can then begin the design of the details and shop drawings. After we receive the shop drawings and get them approved we can specifically begin the design of the foundation systems.

Therefore even though we can begin site clearing and mass grading we can’t begin construction of the foundation systems until that specific portion of design is finished.

The foundation systems are on the critical path of this project schedule. There does not leave an ample amount of time to construct this facility unless the Forest Service is looking to pay an accelerated construction fee (specifically in overtime charges) at bid time to meet the 320 calendar day duration. If the Forest service is on a tight budget this contract should be extended to 540 calendar days. If the forest service is in immediate need of this facility within the 320 calendar day duration it can be done but it should be anticipated that this short duration will greatly affect the proposal pricing so that the contractor can accelerate his design team, material suppliers, subcontractors, and workforce to meet the schedule. We request that the contract duration be extended to 540 calendar days. Answer: Request denied.

5. In the pre-bid meeting notes dated March 13th, question 18 states that the back-up generator shall supply enough power for “essential services”. Can you please define “essential services”? Answer: “essential services” are defined in the Statement of Work (SOW), section 2.3.8 and in the Specification 26 32 10

To preface many of these questions, understand that this system is not a public water system.

1. Is the Prime responsible to obtain the Public Water System permit for this facility, or is this provided by the Owner? I see that the Prime in responsible for the well drilling permit, but the water system permit is a different thing entirely. Answer: Forest Service will obtain the water system permit.

2. If the prime to obtain the Public Water System Permit: Is the Prime also responsible to provide the Source Water Assessment for the water source (wells) or is this being provided by the Owner? Answer: This system will not require a Source Water Assessment.

3. Underground water tanks. All underground storage tanks, regardless of product contained, require monitoring wells. I quote a little known code section on this subject below:

Article 6. Distribution Reservoirs

§64585. Design and Construction.

(12) For a subsurface reservoir, (E) Provided with a minimum of two groundwater level monitoring wells drilled to a depth at least 20 feet below the reservoir bottom and sited within 100 feet and on opposite sides (up-gradient and down-gradient) of the reservoir;

and---. I do not see where the regulatory required monitoring wells are to be placed, nor is there any specification as to the completion details of these wells. Answer: this system is not a public community well. Monitoring wells not required.

4. I do not see source water meters, as required by California Title 22 § 64561, on any of the plan sheets. I did find a meter on the “jet” pump, but this is not the source per Title 22.

Answer: install as shown on the drawings.

5. California Bulletin 74 (AKA: the California Water Well Standards, and referred to in the specifications) §10.A. and Figure 7 requires some way of monitoring the water level in the well. I do not see a sounding tube or other method of obtaining water levels on the well detail page CP5. Am I to quote this item or omit it from my current bid then ask for a C/O later? Answer: While a detail of the sounding tube is not shown in the drawings, full compliance with the State Water Well Standards is expected per contract Specification 33 21 13, Section 1.04 A. Therefore, a sounding tube should be included as being fitted through the well cap per Bulletin 74.

6. Page CP5, KEY NOTE 1, there is reference to an existing well. I only see one production well on the plans. California Title 22 §64554(c) requires a minimum of two water sources.

Where is the existing well? How is it to be tied into the system? Answer: 2nd well is not required.

7. Page CP5 KEY NOTE 4, calls out for a “pitless adaptor” to be used on this project. A more locally common method of well head completion (and preferred by Bulletin 74) uses a “Well seal” in lieu of a pitless adaptor and well cap. A “well seal” is significantly less money. I want to be sure that other that are quoting this project are quoting, apples-to-apples. Should I quote the “well seal” or Pitless adaptor and well cap? Answer: install as shown on the drawings.

8. Page CP5 KEY NOTE 6, calls out to “increase pipe size to 2-1/2” at pitless adaptor”.

Standard practice is to increase pipe size after the ball and check valves, especially if the pump capacity is less than what is needed to fully open the check valve. A 2-1/2” check valve requires about 80 GPM to fully open V/S a 1-1/4” valve, which is all that is needed for the desired 20 GPM production. The smaller valves are a significant cost savings, and will perform better for a longer period of time. Also this should be a SPRING LOADED check valve, not a SWING check valve. Answer: install as shown on the drawings.

9. Page CP5, KEY NOTE 13 calls for a torque arrestor and RING (should be SPRING LOADED) check valve to be installed every 50’. Most pump manufacturers only recommend the check valves to be installed every 200-300’. Some only recommend one check valve and include it in the pump assembly. Adding as many check valves as the plans call for; is adding a significant amount of pressure on the pump, -will significantly reduce the pump output, -and add significant cost to the pump system. Should I include the amount of check valves the plans call for or use the amount recommended by the pump manufacturers? Answer: install as shown on the drawings.

10. Page CP5 Sample Tap Detail and Well an Enclosure Detail. The sample tap is incorrectly located per regulatory requirements. California Title 22 §64560(c)(3)(E)2 requires the sample tap to be located between the well head discharge and the check valve. Answer:

install as shown on the drawings.

11. Page CP5 Well and Enclosure Detail. I do not see a “discharge to waste” valve as required by California Title 22 §64560(c)(3)(E). These discharge valves are typically located at the well head discharge piping, between the well head discharge and transmission piping, with their own check valve to protect against backflow. Answer:

not required.

12. Page CP5 Well and Enclosure Detail. California Title 22 §64560(c)(3)(E)1 requires “Fittings and electrical connections to enable chlorination facilities to be readily installed;”.

I do not see these fittings or electrical connections on the drawings or specifications?

Answer: not required.

13. Page CP5 Well and Enclosure Detail. Typically the locations of the union, ball valve and check valve are in exactly the opposite order as shown. Reasoning behind typical practice: The well pump is always shut down to replace a check valve, or well pump.

However, there is usually back pressure on the transmission lines that would prevent the union (as shown on this drawing) from being opened to either replace the check valve or well pump without shutting down and/or draining the transmission piping. If the ball valve is the last component in the line of flow towards the transmission piping, it can be shut off to replace either the check valve or well pump without draining the transmission piping and potentially allowing contamination into the distribution system. Answer: install as shown on the drawings.

14. In the Specifications, section 33 21 13, Paragraph 3.08 a well test is described. The described test does not appear to meet with the minimum specifications in Title 22 §64554(g), as most likely the well will be constructed in fractured bedrock. The pumping test described in the specifications is only 8-24 hours with an undetermined amount of recovery data collection. Typically a 72 hour test is required, with an undetermined amount of recovery data for wells constructed in fractured rock. Also the well tests of this type, when submitted to regulatory officials for Water System permitting purposes, are usually only accepted when the test was completed during the 3-dryest months of the year (August, September, October). Answer: test to be done according the specification.

15. Bid pricing. Lines 33 21 13D and 13E indicated 8” Liner. Specifications 13 21 13 1.06-A-3 and A-4 call out for 6” minimum diameter. Based on the written specifications and well design it impossible to construct the well with an 8” Liner. I suspect that the 8” is a typo and supposed to be 6”? Answer: see amendment for well changes.

16. I do not see complete specifications for the “Jet Pump” described on drawing CP4. The power requirements are partially shown, but the pump capacity or volume, and horsepower, are not shown. There are also piping issues which can be corrected later at no additional cost. Answer: remaining design elements to come from designer.

17. If the pump in drawing CP4, is to supply water for firefighting purposes, the installation shown on this drawing does not meet the requirements in the NFPA 20-03, and NFPA 70-11 standards for a number of reasons:

a. The fire pump must have a minimum of 0-PSI at (flooded suction), thus the tanks must be higher than the pump.

b. The fire pump “shall be physically separated or protected by 1 or 2-hour fire-rated construction”,

c. The power source to the fire pump must be physically separated from other building supply’s, and the main building disconnect, to prevent the power to the fire pump from accidently being shut off. The electrical drawings have power to this pump going through several other service panels, the same transfer switch as the buildings, and the well pump is also on the same service lines. Answer: Stand pipe is for tanker fill only.

18. Page CE6 Submersible Pump Control Schematic and Submersible Pump Enclosure electrical. There are many issues with these details;

a. The “Pump Control Box”, and “Franklin Pump-Tec-Plus”, are not used with 3-phase power, these are 1-phase components. Since 3-phase power is proposed, I propose replacing the Franklin Pump Tec-Plus with a Symcom Motor Saver 777. The 777 also replaces the Thermal Units, as it also provides overload protection. Answer: Sheet

CE6, detail 1: delete Franklin Pump-Tec-Plus and replace with Symcom Motor Saver 777. Also delete Thermal Units. Detail 2: delete pump control box.

b. The drawings show a NEMA 1 enclosure on the motor starter, and NEMA 3R for the safety switch and control relay. All three components should be NEMA 3R and are available, as a COTS product, in a single 3R enclosure, in a component known as a Pumping-Plant Panel (PPP). The PPP is a; faster, cleaner, and more reliable method of installation. Answer: Sheet CE6, detail 1: change NEMA 1 enclosure to NEMA 3R enclosure.

c. This area is known to freeze, and break pipes/valves. It is highly recommended that pipe heating cable be installed on the discharge piping at the well head. This will require an additional electrical connection at the well head. Answer: Part of what the designer should design for.

John L. Walters PLS

1. My question is with regards to offsite utilities. The five page sketch provided by SDGE has a graphic location but no details for alignment and transformer placement. In addition, AT&T has no detail location of the trench and pedistals. Will SDGE and AT&T furnish these plans in the future or by chance have I missed the proposed drawings.

Answer: The location of SDG&E/AT&T trench will be located east of the 50’ Right-of-Way from centerline of Kitchen Creek Road within a 20’ corridor, but as close to the ROW line as possible. The SDG&E work order will be provided to the selected contractor.

Kevin Rentz, DSCM, Inc.

1. In the specs under Asphalt Products 2.3, they call out for Asphalt Restraint Edging. They refer to a product called “Permaloc Asphalt Edge”, yet the plans don’t show it and there is no line item in the bid schedule for it. Also, I believe all new asphalt along Kitchen Creek Road has an asphalt berm, so there should be no need for a restraining product. Is this correct? Answer: that is correct.

2. The SDG&E drawings provided are diagrammatic and are lacking critical information regarding the structures required at various locations also grounding information. We did speak to the SDG&E planner and got some answers. The 12 " T " symbols stand for a above ground terminator cabinets. However, not knowing the right of way dimensions for the entire run, there may need for barrier posts for protection, or retaining walls to obtain a 8 foot level work area, in order to install these structures. Underground handholds (vaults) would be a viable solution to these problems, at least along Kitchen Creek Rd.

and would be less visually obtrusive. Is this an option? Answer: That would be SDG&E’s decision.

3. There will be approx. 600 cu. yards. of excess trench spoil if the natural soil does not conform to SDG&E standards, is there going to be an area onsite for disposal? Answer:

Yes. COR will determine a placement location within a standard haul distance.

4. There is a section in the specifications relating to material that generated on the initial clear and grub grading process. Is it possible to bury the grassy material in fill areas that have no structural value (I.e. buildings or concrete going over top of)? Or do we need to haul this material off-site? Answer: No. This material needs to be disposed of at a proper disposal facility. See KCHB Specification 31 10 00, Section 1.2A.

5. There is a section in the specifications that state that the Foam Fire Suppression System is to be designed after the design of the hanger building is approved. Are we to include pricing in our base bid for this system? If so, do we include those dollars in the lump sum price for the hanger? Answer: Yes and Yes

6. The Septic System is a design-build element of this project. However, we have not been provided results from a percolation test which I believe is to be provided by the Forest Service. How should we price the leach fields for this item? Is the Perc test to be supplied prior to the bid due date? Answer: Septic systems are not design/build.

Septic tanks are 1000 gallon and leach fields are as follows: Office building has 3 laterals with 15 infiltrators per lateral. Hanger has 3 laterals with 13 infiltrators per lateral.

7. In the specifications there is mention of a subsection of Division 1 pertaining to Allowances. We could not find any section on Allowances. Are there items that should be treated as Allowance? Answer: Referenced specification is not indicated. We don’t have any “allowances”.

8. Are the windows to be vinyl or wood clad? There is a discrepancy between the materials that were sent out. Answer: Wood Clad. See Statement of Work, Section 2.2.2.1, paragraph 3.

9. Are the interior doors to be hollow metal, per the specifications? Or wood doors similar to Happy Camp? Answer: Exterior doors are to be solid core metal doors. Interior doors are to be solid core wood.

10. Are the doors to have vision lights and/or transoms? If so, which doors have these features? Answer: The main/front door to the office building (day room) shall have a vision light. No other vision lights or transoms.

11. Is there any local government agency that is going to review the design-build plans for the structures (i.e. County of San Diego)? If so, how do we calculate the fees for this review, inspections, etc? Answer: only the Forest Service will review the plans. No fees involved.

12. In the section of the specifications pertaining to Quality Requirements, it mentions that the GC is responsible for ALL fees to be paid to ALL Government Agencies. How should we determine what those fees will be? Which Government Agencies will we be dealing with on this project? Answer: Contractor is required to obtain permits and pay all associated fees for the following items: Well drilling application fee – San Diego

County. See spec 33 21 13, section 1.03 C. A National Pollution Discharge Elimination System (NPDES) Permit through the State Water Resources Control Board (SWRCB) – See spec 01 57 24, Section 3.1

13. The specifications make mention of air monitoring for airborne Lead particles. Is this to be provided by the Forest Service? Answer: No. If needed, it will be provided by the Contractor. See Statement of Work, Section 6.4

CHULA VISTA ELECTRIC CO

1. The description of work, in paragraph2.2.2.5, states we are to provide cables and blank outlet covers for voice/data outlets, while the spec section requires jacks, racks, cable trays, terminations, testing, and drawings for a complete system ready to accept Govt.

Provided equipment. Please clarify the extent of work required of the telecomm subcontractor. Answer: Install according to Specification 27 00 00. The government only provides the network router and switch. All other materials and equipment including the UPS should be provided by the telecom contractor including termination and testing of cabling

2. Please clarify the intent of the helipad. Is the hose reel for firefighting or for refueling?

How is fuel handled on this site? Answer: Hose reel is only for washdown of the helipad. Fuel is handled by tanker truck which will be parked in the containment area.
