Amendment Four Attachment One
| Date Submitted | RFP Location | Question | Responsible Party for Answer (for Government Use) | Answer (Government Use) |
| 8/4/20 | Upon review of the solicitation/contract documents we have NOT identified a requirement of having a bona fide office within the geographic region of this project. Please confirm that this is accurate, that this is not a requirement of the bidding contractor. If this is in fact a requirement, can you please confirm that we can provide this prior to project award to allow for ample time for this to be set up with the local SBA office instead of prior to bid submission? | Christina Schofield | See Section L, clause 52.219-18, Alternate 1 for the geographic region for this project. | |
| 8/4/20 | Solicitation Document | When are the formal pre-bid RFIs/Questions due? What is the due date? | Christina Schofield | The presolicitation questions were to be submitted by July 31, 2020. The second RFIs/questions were to be submitted by 1600 August 14, 2020 as detailed in Amendement Two. |
| 8/4/20 | Drawings (throughout) and Schedule of Items | Are we to include the "Option Items/Option Work Items" in the schedule (required for the proposal)? | Todd Michael | Yes |
| 8/4/20 | Drawings page C300, A020 and A902 | Is the detail on pages A020 (Detail W2080) and A902 (Optional Trash Enclosure) reference for the Trash Enclose shown on page C300? Confirm this is an "Optional Item/Optional Work Item." | A/E | Optional Item. Please refer to Spec Section 010250, Option Item list. |
| 8/4/20 | Division 12, Sections 122400, Drawings pages A611, A616 | It is unclear as to whether window coverings (shades) are optional or a base item. Please clarify which window shades, if any, are part of the Base Items. | A/E | Window shades are an optional item. |
| 8/4/20 | Drawings page A030, Demolition General Notes, Note #8 | If each utility trade safes-off, caps, prepares their utility for demolition, could then all the building-related demo be performed by one subcontractor? For example, if the plumber capped-off their lines, and the mechanical capped off their lines and ducting, and the electrician's safed-off their work, could then a demo subcontractor demo all the work? | A/E | This is a means and methods item and should be determined by the General Contractor on the best method for completing the project. The Government does not determine which sub contractors perform the work. |
| 8/4/20 | Drawings page A002 - General Notes, Construction Note #7 | Could you provide examples of areas noted as "concealed spaces" and "chases" where fireblocking will be required? If so, please provide. | A/E | This note is clarified on A010, under the heading 'CHAPTER 7 - FIRE AND SMOKE PROTECTION FEATURES > Concealed Spaces 718' |
| 8/4/20 | Drawings pages A251, A750, E005 | Is the contractor to provide the video projector? If so, are there specifications available? If so, could the Government provide the specifications? | Todd Michael | The videow projector is government furnished and installed. |
| 8/4/20 | Drawings page E002 (131 of 146) Detail #1 Note "D"; page E030 (136 of 146) Electrical Demolition Requirements Note "C", Page E040 (137 of 146) Electrical Demolition Requirements Note "C". | There appears to be an exsiting fire alarm system, and the drawings indicate tying into the existing system as it pertains to door access security. However, under the Electrical Demolition Requirments, the drawings indicate to "Remove . . . all . . . fire alarm components." If the "all" fire alarm components are being removed, to what shall the impacted doors "interconnect" to? Furthermore, is replacing the fire alarm system components to be included this project? | A/E | Similar to other fire alarm comment responses on the same topic, the existing fire alarm system and associated devices are to be demolished. A fire alarm system is not required for the project. Since there will be no FA, interconnection of the security system to an FA system is not required. |
| 8/4/20 | See also page A010, "Project Data Summary," "Fire Alarm & Detection." | No "Summary" was provided for the fire alarm and detection system. Could the Government provide information on the existing Fire Alarm System (As-Built drawings)? With the demolition of a portion of the facility, there would most likely also be a modification of the existing fire alarm system. No replacement devices are indicated. Please advise. | Todd Michael | A fire alarm system is not required for the project. The fire alarm system and associated devices are to be demolished. |
| 8/4/20 | See page A010 - Code Analysis, "Chapter 9 - Fire Protection". | Is there a wet/dry-type fire suppression system in the existing facility? Will any of this be demo'd? After demolition of a portion of the facility, is there work that will need to be peformed to the existing system (if one exists) to reconnect? We found no information in the drawings or specifications on the fire suppression system. If there is an existing system, are calculations available? Are existing fire suppression system as-built drawings avaialbe? With interior renovations required of this contract, there would most likely be a need for modification of the existing fire suppression system. Please advise. | Todd Michael | There is no wet/dry-type fire suppression system in the existing facility. There is no new system either. |
| Pre-bid | Where identified submittals are required to be utilzed. Who pays the cost of the Submitttal Exchange project subscription? | Todd Michael | The government will pay the cost of the Submittal Exchange project subscription. | |
| Pre-bid | The construction documents show footers to be demolished. Do the footers need to be removed or can they be abandoned in place? | Todd Michael | Remove the footers. | |
| Pre-bid | During the site visit it was apparent there is residential property on several sides of the property. Are there any construction restrictions? | Todd Michael | On-Site Work Hours: Work shall be generally performed during normal business working hours of 7:00 a.m. to 5:00 p.m., Monday through Friday, except as otherwise arranged with Contracting Officer. | |
| 8/11/20 | Please confirm that the building is code compliant without a fire suppression system, either wet or dry type. | Todd Michael | The building is code compliant without a fire suppression system. | |
| 8/11/20 | Is there exsiting water supply onsite that can be utilized for dust mitigation, washing tools, mixing materials, etc.? If so, are there any limitations or requirements with respect to their use (e.g. metered)? Will the contractor incur costs for using the water source? | Todd Michael | As indicated in Section 015000 1.2 A. The contractor provides temporary water facilities for the duration of the project. | |
| 8/11/20 | Whose responsibility will it be to notify the local residents of access way closures? Upon the site visit, it was noted that many vehicles cut through the parking lot within the limits of construction. Access to this area will be closed off for construction activities and public safety. | Todd Michael | The Forest will coordinate the street shutdown with the town and provide notification. | |
| 8/11/20 | Are there any "protected plants or animal species" within the limitis of construction (bushes, trees, squirrels, etc.)? | Todd Michael | To our knowledge there are no protected plants or animal species within the limits of construction. | |
| 8/11/20 | Just outside the limits of construction it was noted that brush and bushes are over-growing and could potentially present as a fire hazard during peak fire hazard times. Who is responsible for keeping these areas under check to mitigate fire hazards? | Todd Michael | The Forest Service will minimize fire danger outside the designated project area. The contractor is responsible for mitigation inside the designated project area. | |
| 8/11/20 | Please confirm that the construction schedule provided as part of the technical requirements should reflect the 18-24 month project duration. | Christina Schofield | Confirmed. | |
| 8/11/20 | It was mentioned on the post-site visit teleconference of 08/11/2020 that it was up to the discretion of the contractor the number of personnel who MUST be onsite. The question was asked specifically if the Scheduler and/or Project Manager MUST be onsite. The response was that it was up to the discretion of the contractor. Please confirm that if the contractor does not deem it necessary to have the Scheduler or Project Manager onsite, this will be acceptable. | Christina Schofield | Confirmed. | |
| 8/11/20 | For the purposes of determining the start date for the construction schedule, December 2020 or January 2021 start date was indicated during the post-site visit teleconference. Could you please provide the anticipated start date? | Christina Schofield | The anticipated start date on the ground will begin in January-February 2021, after successful completion of Phase One of this project. | |
| 8/11/20 | Please confirm that the security system MUST be Linell. | Todd Michael | The access control and security system must be Lenel as described in specification 280500 1.1 B. and C. Additional paragraphs in this section outline requirements for Lenel VAR and certifications. | |
| 8/11/20 | Page E002, Detail 1 - Door Access Control System One-Line Diagram - Regarding the Access Card Reader. | This detail directs the reader to E300 series drawings. There is no Page E300 as part of the contract drawings. Could you please provide us with the referenced series drawing? | A/E | There is a typo on that detail. The reference should say "REFER TO SHEET E111, OFFICE TECHNOLOGY PLAN, …". |
| 8/12/20 | No manufacturer has a mod furnace that will deliver the output capacity called out at that elevation on derated gas. You might be better off with a two stage, variable speed. Can you confirm what you want us to price? | A/E | Price the modulating furnace as specified, or as described in the brand name or equal clause. | |
| 8/12/20 | If the Micro-metal economizer with Jade controls is put on, the EAT on the furnace will be less than the 55 degree minimum at design conditions. That will void the warranty, and add two thousand per furnace. Would it not be better to just put in HRV's and temper the incoming air? | A/E | Price the economizer with Jade controls and warranty specified. Address concerns with voiding the warranty as an RFI after project award. | |
| 8/12/20 | SECTION 101400 SIGNAGE | Specs mention exterior individual metal letter signage. I do not see any exterior signage called for in the plans, can you confirm? | A/E | There are pin mounted letters on the entry desk, see A611. |
| 8/12/20 | Sheet A030 | Callout - Salvage exterior wall veneer; is this intended to just have enough brick to make small patch repairs throughout, or does the Owner want all brick veneer salvaged and stored? | A/E | Only salvage what is required for patches and repaired with construction. Any additional veneer shall be removed, not stored. |
| 8/12/20 | Can we get a full size / scalable set of plans? | Todd Michael | Contractors can print the plans at any scale they need. The government does not provide prints of plans. | |
| 8/12/20 | Please provide a spec for the dishwasher. | A/E | See Attachment 2 to Amendment Four. | |
| 8/12/20 | Can you confirm Fire alarm is not required? Vol II mentions it in footnote, Vol III mentions it as part of sequencing for access control, but no other mention | A/E | Similar to other fire alarm comment responses on the same topic, the existing fire alarm system and associated devices are to be demolished. A fire alarm system is not required for the project. | |
| 8/12/20 | KeyNote 12 Sheet E100 | “EV Charging Station Bollard Mount Base”; Can you provide a spec for the charging station or a detail on the base? | A/E | EV Charging Sepcification is located at Section 262726, Wiring Devices, Section 2.10. Provide base as required by manufacturer. |
| 8/12/20 | LP103 N3 | The Q&A in Amendment 2 seems to have been misunderstood. LP103 N3 is for new trees, and your response regards existing trees. Since the Contractor is not responsible for new trees, only shrubs and perennials, and any new trees by the Owner would be at the end of the job, it seems this requirement is not needed. Can you confirm? | A/E | DHM: 1/LP103 is for existing and new trees. See note #1; "Existing trees to be protected during demolition and construction." Tree fencing for new trees will be the responsibility of the Government. |
| 8/12/20 | SECTION 115213 PROJECTION SCREENS | Regarding installation of the motorized projection screen Installer Qualifications, based on the review of the installation instructions, JITA Contracting believes we are capable of handling the installation in house, will this be acceptable? | A/E | General Contractor may provide statement outlining qualifications of installer prior to instllation for consideration. |
| 8/12/20 | Detail 1 sheet S504 | Regarding Detail 1 sheet S504, where in the plans is this detail used? | A/E | It is a typical detail and not cut on the plans, but would apply to the connection of the W8x10 beam on grid line A between grids 13 and 16 and of the W8x18 beams on grids 11 and 12 at grid line B. |
| 8/12/20 | S102 | On S102, the East entry vestibule, gridline 10 to 12, line B, there is an 8x10’ new beam shown – Could you lead us to where the beam connection is shown on the drawings or provide? | A/E | The beam would be connected to the HSS4x4 posts per 1/S504 |
| 8/12/20 | Can you provide wage rate for flooring? | Christina Schofield | The Building Construction wage rate (CO20200001 01/24/2020) for Laborer appears most appropriate for flooring work for this project. | |

| 8/14/20 | Is the contractor required to permit the project through the State of Colorado? | Todd Michael | The contractor needs to obtain a stormwater permit. Building permits are not required. | |
| 8/14/20 | Line item 5, 6; C300 | Asphalt Employee Parking A, B - Please guide me to where in the plans it shows the delineation of these two lots? Are we assuming the striping for the optional asphalt items to be the same as the "Parking stalls not striped (for graphic puposes only). Typ." on LS101? Should we assume A is the closest to the building and stops at the valley pan on the west side? And should we assume with B that we will pave the connector road sections? | A/E | Parking Lot A is closer to the building and includes asphalt from the limits of paving in Base Bid on the east, to the concrete pan on the West. Parking Lot B is further from the building and includes the parking lot and drive ailes from the limits of paving in Base Bid on the east, and the line marked 'Extents of Optional Asphalt Paving' on the West.

| 8/14/20 | Section 321200 Flexible Paving | Part 1.4.D.8 Sampling and Testing of asphalt concrete mixtures during paving operations. Paragraph c. states to perform at least one test for each days paving or 4,000s.f. of each lift. Does this refer to density, or asphalt cement content and maximum specific gravity tests also. For reference 4,000 s.f. at the maximum depth of 3” is about 75 tons of mix, and at a 2” thickness will be testing every 50 tons. Section 3.10 Field Quality Control D. Asphalt Density testing is defined at one per 2,000 square feet. Please clarify testing frequency and whether it is density or ac content and Rice values also. Testing frequency stated is much more typical for large scale production, not a 500 ton parking lot. | A/E | Asphalt density testing to be performed per 2,000 square feet per lift. AC content and RICE testing to be performed once per day or per 4000 sf for each lift, whichever is more stringent. |
| 8/14/20 | Section 321200 Flexible Paving | Part 2.1. E calls for a minimum sand equivalent of 45 for Asphalt Base Course Aggregates, and Part 2.1.F calls for a minimum sand equivalent of 50 for Surface Course Aggregates. CDOT requires a minimum of 45 for all asphalt aggregates. Our current mix designs fall between the 45 and 50 value, would the USFS Consider a 45 minimum value for the Surface Coarse Aggregates? If not a project specific mix design will be required at additional approximate cost of $6,000 for 500 tons of asphalt pavement. | A/E | Mix design will be reviewed for all properties with project submittals. A minimum sand content meeting CDOT standards will be acceptable. |
| 8/14/20 | Section 321200 Flexible Paving | Part 3.2.D Tack Coat 1. State to apply in similar manner as prime coat, except as modified. No requirement for prime coat is found and in our opinion needed or desired. It has been decades since we prime coated a parking lot. Is a prime coat required? And if so, please provide specifications. | A/E | Mix design will be reviewed for all properties with project submittals. A minimum sand content meeting CDOT standards will be acceptable. |
| 8/14/20 | Section 321200 Flexible Paving | Part 3.7 F. Lift Thickness: Table shows lift sequence for 5” paving, but not 5.5”. Top lift is specified to be 2” maximum thickness. Can bottom lift be installed at 3.5” or can top lift be 2.5” to match heavy duty pavement section. | A/E | Mix design will be reviewed for all properties with project submittals. A minimum sand content meeting CDOT standards will be acceptable. |
| 8/14/20 | Sheet CD302 | Thickened asphalt edge is very confusing. References are made to asphalt paving and aggregate base course in the same section. No width is identified for the thickened edge and thickness says varies. Please clarify. | A/E | Mix design will be reviewed for all properties with project submittals. A minimum sand content meeting CDOT standards will be acceptable. |
