Sheet1
| Question | Answer | Addressed in Amendment: | |
| 1 | If proposing as a Joint Venture formed under the 8a Mentor/Protege relationship – do RFI’s and other pre-proposal correspondence need to be in the name of the Joint Venture? | No the correspondence and questions prior to proposal submission do not need to be in the name of the JV. | 1 |
| 2 | If proposing as a Joint Venture formed under the 8a Mentor/Protege relationship -- does the Joint Venture need to demonstrate experience/qualifications as a separate entity or can it propose using individual joint venture partner qualifications? | JV or individual JV Partner qualifications are acceptable. | 1 |
| 3 | Solicitation page 47, subsection B: Please define the word “day” in the phrase “10 days” in reference to the minimum amount of lead time for pre-proposal questions ahead of the bid date? (Calendar or business day) | Calendar days, May 5th questions are due. | 1 |
| 4 | In the zip folder for B08_Attach_1b2 there are files with a suffix of “.ai” that do not open under any platform we know of? Please provide clarification? | The Road Guide Sign Layouts pdf provided has the same information as the .ai files. The .ai files were provided for use by the contractor’s sign fabricator, they are Adobe Illustrator files | 1 |
| 5 | Are there any areas proposed as work zones where the ground conditions may be unreasonably “unsafe” due to terrain|slope-stability compromised by the initial eruption event and/or subsequent events? | We do not have any information/evidence that the area is unsafe due to the eruption and subsequent seismic/volcanic events. The limited instrumentation we have in the HVO, Annex, and Jaggar Museum area indicates that there have been some minor ground motions since July 2020. These millimeter scale motions, expansions and contractions, could crack foundations but shouldn't cause any issues with demolition work or lead to safety concerns for people being in the area. Large equipment shall stay away from caldera cliff edges. Large equipment utilized for the dismantling of the facilities shall work from the west side of the HVO facility. | 1 |
| 6 | Is there an onsite staging area specifically identified for “green waste”; so, such piles of vegetative debris can be screened for types of flora/fauna/fungus species unwanted at the local landfill? | No specific areas have been identified for green waste staging. The park natural resource specialists have confirmed that park generated green waste has not been a concern for the landfill / county green waste facility on past park projects and we do not anticipate this being a concern on this project. | 1 |
| 7 | Will water for use during all construction activities be provided to the contractor? If so, is it free of charge, where is the source located, and how much water will be made available? | Refer to specification section 01 50 00 Part 1.3: Water Service: Limited potable water is available in the vicinity of the project sites. Contractors shall be allowed to use up to 4,000 gallons of water per day. See 01 50 00 Part 3.2: Non-potable water for construction is not available within the park boundaries. Contractor shall furnish non-potable water from a source outside park boundary as needed. | 1 |
| 8 | There are a few plan notes requiring the contractor to provide temporary water during construction activities for either facility operation and/or visitor use? Will a water source be provided, if so, will the water be free of charge, where is the source located, how much water will be required at each of the facilities/area of use, and how much water will be made available? | Refer to specification section 01 50 00 Part 1.3: Water Service: Limited potable water is available in the vicinity of the project sites. Contractors shall be allowed to use up to 4,000 gallons of water per day. See 01 50 00 Part 3.2: Non-potable water for construction is not available within the park boundaries. Contractor shall furnish non-potable water from a source outside park boundary as needed. | 1 |
| 9 | Plan sheet 01-X103 references “equipment to be sold by contractor to a local equipment reseller” for an above ground diesel fuel storage tank, generator/dry tank/transfer switches/etc., fire pump/accessories, chiller, boilers, vav air handlers --- and other similar notes exist within the documents for the generator, boiler & day tank, and other MEP systems. Please provide clarification regarding the term “local resellers” for Hawaii Island; and more specifically, once such equipment is “sold” who owns the proceeds? Is the contractor acting as an agent/broker for the government in the act of “reselling” or does the subject equipment become the property of the contractor upon removal and all “reselling” efforts, including potential proceeds become a benefit/burden to the contractor? | All proceeds from the reselling of salvaged equipment and material are the contractor's (successful offeror). All salvaged equipment and material becomes the property of the contractor and all “reselling” efforts, including potential proceeds become a benefit/burden to the contractor. Specification section 02 41 16.13 includes a list of Local Salvage/Deconstruction Companies and Recycling Receivers and Processors. The NPS is keenly interested in implementing a sustainable approach for waste management during construction. There is a solicitation evaluation factor related to this requirement. A technical approach that demonstrates the diversion of higher quantities of material from a landfill will be more favorably rated. | 1, 2 |
| 10 | General note 7 on the Fiber Optic Plans states, “…NPS will complete the clearing and removal of vegetation and trees…”; will the NPS be performing clearing for the Waterline work and any other similar clearing needed for the entire project? | The park will complete any required clearing for Contract Line Item Number 7: PMIS 196582 - Replace Water Distribution System and Contract Line Item Number 8: PMIS 258076 - Replace Fiber Optic Lines. The contractor will be responsible for additional clearing associated with the remainder of project. | 2 |
| 11 | General note 9 on the Fiber Optic Plans states, “Existing Overhead comm lines will be relocated to underground and co-located in trench with fiber optic line, see note 8.2. Contractor shall be responsible for trench, all utility service fees, and coordination with utility service”; please provide all information needed for the contractor to properly quantify the referenced work, to understand/gain knowledge as to who the system belongs to, and how it would estimate the service fees associated? A contractor needs much more information for such a far-reaching ambiguous note. Please consider converting the referenced work to a fixed ALLOWANCE amount, that will be the same for all contractors -- otherwise some contractors may miss this note and put no cost in their bid for the work, while others may put a very large value in their bid due to the risk associated with such an ambiguous note. | The NPS will be issuing an Amendment that clarifies General Note No. 9 and the collocation of telecom in the NPS fiber optic trench. The topic will also be discussed in the May 4, 2023 preproposal meeting. | 2 |
| 12 | Second paragraph in the general notes on sheet 23 of the “Replace Failing Water Distribution System” plans reference “unit price bid items” intended to compensate the contractor for an unknown number of “bollards” and such? Please provide a basis for the contractor to use to determine the number of “Type I” and “Type II” support structures, and provide clarification regarding the fact that the referenced “unit price bid items” are no longer on the bid form? | The NPS will be issuing an Amendment which will include an updated CPS with quantities and specification section 01 27 00 with CLIN descriptions that the offerors can use as a basis for cost. | 2 |
| 13 | Reference Specifications 02 41 16.13 - 6 to -9 (Page 23 to 26 of 508) |
It is likely that there are no current | feasible on-island options for recycling/reuse of wood, gypsum board/drywall, acoustic ceiling tile, structural steel, etc. Additionally, the labor and effort required for manual removal and onsite sorting of these building components often proves to be cost prohibitive (especially if a full analysis is performed to include shipping of debris off-island, mainland rehandling costs, full carbon footprint types of costs, etc.). Dismantling efforts required to achieve the degree of sorting and segregation as outlined in this Specifications section will drastically increase the required labor/manpower, substantially increase project costs and schedule duration, and present unnecessary worker hazards of structural collapse and injury due to increased manual handling/labor. Standard mechanical demolition will involve the top-down demolition of the structures utilizing an excavator equipped with a processor or bucket/thumb and can effectively sort scrap metal (including structural steel, piping, tanks, and ductwork) and concrete/CMU masonry for recycling. All other ‘soft’ building components (as outlined above) are non-recyclable and thus will need to be disposed of offsite. Please confirm that mechanical demolition operations as outlined above will be an acceptable alternative to dismantling. Additionally, please confirm that wood, drywall, acoustic ceiling tile, and other non-recyclables will be permitted to be disposed of at West Hawaii Sanitary Landfill as Construction & Demolition (C&D) debris.
| Structural steel and other recyclable scrap material is typically sorted offsite at a designated recycling facility. Given the logistics of the site, the staging, loading, and transport of full structural members in their entirety will involve substantial added cost for trucking, needed equipment, and space requirements. Please confirm that recyclable scrap can be mechanically processed onsite using a shear or other means to maximize loadout efficiency for transport to a recycling facility. | The NPS would like to divert as much material from a landfill as is practical and there are many ways this could be accomplished. Shipping material off island and similar approaches that result in a net increase to the carbon footprint are not desired. Materials considered no-recyclable on island can be disposed of in a local landfill. It is acceptable to mechanically process recyclable scrap on site. A preproposal meeting is scheduled on May 4, 2023. Any interested offerors will have the opportunity to review the project sites, including the interior of the facilities scheduled to be demolished in the Uēkahuna Bluff area. | 2 | ||
| 14 | Please address which State and County permits are required for this project; we are not aware of anything at this level other than the NPDES permitting administered by the State of Hawaii Department of Health, Clean Water Branch? | The NPDES permit is to be obtained by the contractor. Contractor also responsible for preparing and submitting the documents for the Nāmakanipaio Campground temporary potable water supply configuration to the State of Hawaii Department of Health for review and approval. | 4 | |
| 15 | Will contractors be allowed to work at night to reduce overall impact to NPS operations and park Visitors? | No night work will be allowed to protect dark skies and night-active species, such as the Hawaiian petrel. | 2 | |
| 16 | In accordance with FAR 9.6 will the NPS accept past project experience of our key subcontractor? | Yes | ||
| 17 | Reference Specifications 31.10 00 3.3 (Page 377 of 508); Plans Note 3 (Page 34-36) |
The plans do not specify the size and quantity of seedlings and ferns that need to be salvaged. It is hard to determine how much labor, time, and effort is required to carefully salvage the seedlings and ferns without knowing their sizes and quantities. In addition, specification section
31.10.00 para. 3.3.D states coordinate watering and care of salvaged plants with NPS. Please clarify if the intent is for the contractor to water and care for the salvaged plants. If so, there
| is always the unknown when salvaging and relocating plants. The plants will go into shock, and there may be a lot of plants and seedlings that do not make it. The contractor should not be responsible for watering and care of the salvaged plants or to replace any seedlings or ferns that do not survive. | The only plants to be salvaged alive and relocated are the Hāpu’u ferns, which are very hardy. A total of 500 Hāpu’u are to be salvaged and staged. The salvaged ferns are to be stacked/staged by the contractor in the shade, coordinate exact location in the nearby forest with the Contracting Officer. The Park will replant the ferns. | 4 | ||
| 18 | Plan sheet C27 of Set 124/145330 references a slab detail (3/C27) for “steam vents”; though two (2) are called out in the plans and will be cover in the base pricing --- should others occur, how will the cost of such extras be paid for? | The referenced details on sheet C27 are related to plan note No. 10 on the plan & profile sheets C3 through C13 & note 7 on C14 - C17. The detail is also associated with CLIN 15, a unit cost CLIN with a quantity of 200 lf as the basis of cost. See updated specification section 01 27 00 and updated CPS issued in Amandment No. 2. Variations of actual quantities installed will be addressed through the variation of quantity clause in the contract. | 4 | |
| 19 | Seeing references to “steam vents” in the plans, the issue of safety seems critical considering such ground conditions; are there special protocols/etc. required prior to ground disturbance to locate such dangers or assess for such dangers? | The alignment of the new utilities are essentially in the same alignment of existing utilities. In addition, Park staff will be completing the necessary vegetation clearing for the new utlities. It will be the contractor's responsibility to emplement the appropriate protocols to safely install the new utlities. | 4 | |
| 20 | Responses to RFI001 indicate the contractor’s responsibility to supply potable water if its use of potable water exceeds 4,000 gallons per DAY; however, the contractor is being asked to maintain water availability to two (2) areas beyond the contractor’s control of consumption. How will the contractor know how much water to provide to these two (2) locations? Please let us know an estimated daily consumption for these locations that can be used as the basis for estimating the additional water cost in our estimate? | The two locations referenced in the question are unclear. It will be the contractor's responsibility to provide temporary water supply for the Namakanipaio campground. See plan note 2 on sheet 01-X101 in drawing set 124/175449: Temporary water supply is required at Namakanipaio campground during the duration of water tank demolition and installation. Refer to Amendment No. 2, specification section 01 50 00 Parts 2.1 and 3.2 for campground water demand and suggested temporary water tank size of 3000 gallons. The Park will provide the potable water for the tank, coordinate temporary connection to Park water supply with Park staff. In addition, per drawing set 124/145330, plan not No. 5 on sheets C3 through 14, the contractor is responsible to maintain continuous water service, the estimated demand is 17,000 gal/day.The Park will provide the potable water for the continuous water service, the contractor is to coordinate the method used to maintain the continuous water service with the Park. The contractor will be provided an additional 4,000 gal of potable water per day above and beyond what is described above for the campground and continuous water service. | 4 | |
| 21 | Will the contractor be allowed to stockpile aggregates for use on the project at the staging areas depicted on plan sheet C1 of Set 124/145330? | Yes | 4 | |
| 22 | Regarding the quarry area being provided: Will contractors be allowed to use the quarry area to crush and re-cycle concrete and asphalt for reuse on the project? If so, it will greatly benefit the project. | Yes. Excess material not utilized for the project to be removed and legally disposed of outside the park | 4 | |
| 23 | Since the project is a potential two (2) part selection and negotiation process, will the bid bond be exercised as outlined in the FAR? and if not, is it necessary? | We are uncertain what you are referring to in terms of a two part selection and negotiation process. Regardless, the bid bond is required to be submitted as part of your offer pursuant to the solicitation clause FAR 52.228-1. | 4 | |
| 24 | Please provide better clarify regarding whether project management, project engineers, and superintendents can perform the required safety and quality control roles? | In accordance with project specifications 01 40 00, the Contractor's Quality Control Supervisor may also perform other duties and there is nothing specifically stated in the contract that prohibits the dual roles for either the QC Supervisor or Safety Officer. | 4 | |
| 25 | Please address the following sub-questions from our fiberoptic team member: | |||
| a. | Please confirm fiber shown between bldg. 216 and 344 on telecom backbone schematic diagram alternate on sheet E70 is not in contract as shown on sheets E47 and E48. | |||
| b. | Please confirm housing buildings to receive 6 50/125 mm fiber is as listed here: [11,15,5,22,16,7,3,4,19,6,8,9,18,23,54,37,17 and 20] | To be answered on next Amendment | ||
| 26 | Regarding the deconstruction and demolition of the Jaggar Museum area buildings --- we would like to suggest that breaking up and removing all the concrete and crushing it with the rock used for backfilling will be the best solution for cost, future storm water infiltration, and intuitively for the overall long-term stability of the embankment? Is it possible to have you consider this change? If not, is it possible to hydraulically hammer, breakup, and remove the basement floor area rather than drilling simple holes? We could saw cut the proposed section of basement floor to separate it from what you feel is needed to leave the basement walls structurally stable? | Offerors shall price per the demo plans. The NPS is willing to consiuder value engineering options proposed by the successful offeror after award. | 4 | |
| 27 | Amendment No. 2 provides additional notes that create a dilemma in pricing: The pricing for the relocation of the OH lines shown on Plan Sheet 02-C117 is to be included in the price for CLIN 5: Crater Rim Drive Realignment; however per Note 2 on the same sheet (02-C117) -- if the NPS exercises CLIN 12 / Option D, only the removal of the existing poles would be required since the lines will be buried with the fiberoptic lines; leaving the cost of relocation to be credited since it will not be needed. This creates a level of confusion that could result in bidders pricing each of referenced pricing line items (CLIN 5 and CLINE 12), please help clarify this potential area/item of confusion? | CLIN 12 Option D costs should consider a credit for the elimination of the above grade realignment associated with CLIN 5. | 4 | |
| 28 | Because the bid date was moved, will the RFI question deadline also be moved by reference to that portion of the original solicitation regarding 10-days prior to bid date? | Yes. The RFI question deadline moves relative to the offer due date. It is still 10 days prior to the bid submission date. | 4 | |
| 29 | Will the contractor be able to dispose excess excavated material on or near the work site? | Refer to specification section 31 20 00, Parts 3.4C and 3.4D. Contractor to retain excavated material to be reused on site to the greatest extent possible. Excess material that can be classified as structural fill per specification section 31 20 00 Part 2.1 may be stockpiled in the quarry area for future use by the Park. Excess crushed asphalt and concrete not utilized for the project to be removed and legally disposed of outside the park. | 4 | |
| 30 | Will the contractor be able to dispose excess excavated material in the basement backfill of the USGS Buildings/Jagger Museum complex? | Excess excavated material can be used in the basement backfill of the Uekahuna Bluff buildings if it meets the requirements in specification 31 20 00 part 2.1.A. or part 2.1.C. (except material will not be imported). Excess excavated material meeting the requirements in specification 31 20 00 part 2.1.B. can also be used in basement backfill of the Uekahuna Bluff buildings as long as it not used in the top 40 inches below proposed finish grade. | 4 | |
| 31 | In the basement of the Jagger Museum Complex buildings, there were overhead lines marked acid. (see attached photos) |
Do these lines contain acid?
Is there a holding tank or Pumps that contains acid - related to these lines?
What kind of acid?
What are the hazards associated with this acid?
Are there special disposal requirements for this acid?
| Are there special disposal requirements for these acid contaminated pipes? | The lines marked "acid" are from the old photographic labs. The acid was from the chemicals used to develop film back in the day. Our understanding is that the lines were decommissioned over 20 years ago. The pipes are dry and there are no holding tanks or pumps involved with these pipes. Attached is the SDS for a chemical compound most likely to have been used in the labs. | 4 | ||
| 32 | Please verify if any additional items will be removed from the buildings/structures by NPS prior to the turnover to the contractor for demolition (several comments were made at the site visit eluding to this possibility)? | The NPS will only remove a 160” x 30” piece of countertop that includes sink. Cabinets will remain. This will be completed prior to award of contract. | 4 | |
| 33 | Detail 6/01-L501 on page 77 of 92, in plan set 124-175449, sub sheet no. 01-L501 depicts landscape boulder placement; please provide photo examples and the expected frequency/density/size distribution for such boulder field areas or linear features? It is very hard to price such a broad level of subjectivity? | The locations of boulders to be relocated are shown on the demolition plans. For the Uekahuna facilitiies 01-X103, there are 4 at the north end of Okamura Bldg. Sheet 01-L101 shows the new locations within the footprint of Okamura Bldg to be filled and regraded. These are approx. three- to four-man boulders. Example photo is first one to the right. For the entrance area 02-X101, there are 18 around the existing gravel parking lot and 2 next to the existing road gate. The new locations are shown on Sheets 02-L101 around the roundabout & 103 along the roadside where existing road will be removed. These are approx. one- to two-man boulders. Example photo is second one to the right. | 4 | |
| 34 | Page 70 of 92, in plan set 124-175449, sub sheet no. 02-C301 depicts a number of cross sections with various pavement section configurations; Pages 54 – 56 of the same plan set depict (using hatch patterns) the various areas requiring the different types of pavement. Pages 62 – 65 of the same plan set provide cross section lines/symbols orienting the reviewer to the various cross sections depicted on page 70. With the greatest respect, the assortment of general reference sections with no clear/accurate delineation of length that such sections should be applied, the plans fail to properly communicate where note 7 (the grinding and overlay areas) is to be applied with enough precision to accurately quantify the area and associated cost for the subject work. Please provide a depiction (preferably with a hatch pattern) that clearly delineates, in plan view, the areas requiring cold planing (grinding) and AC overlay? | Station ranges have been added to the sections that previously didn't include station ranges. There is no asphalt concrete overlay on the project and note 7 is no longer used on sheet 02-C301. The asphalt concrete overlay area has been removed from Sections H and I. The limits of asphalt concrete pavement have been revised on sheet 02-C102. | 4 | |
| 35 | Detail 7/02-C505 on page 75 of 92, in plan set 124-175449, sub sheet no. 02-C505 depicts a 2” grinding depth and only a 1 ½” AC pavement wearing course overlay, please verify that indeed the design calls for a thinner replacement layer of pavement compared the thickness of the layer removed? | Detail 6/02-C505 on page 75 of 92 has been removed as asphalt concrete overlay is not proposed in the project. (The question incorrectly identified detail 7, the detail in question is detail 6) | 4 | |
| 36 | Please provide a backfill specification for the structure fill required at the Jaggar building area to fill in the basement area and surrounding areas to prepare for topsoil? | Structure fill required at the Uekahuna Bluff shall meet the requirements in specification 31 20 00 part 2.1.A. or part 2.1.C. (except material used at Uekahuna Bluff cannot not be imported per part 2.1.D.). Onsite structure rock fill meeting the requirements in specification 31 20 00 part 2.1.B. can also be used at the Uekahuna Bluff as long as it not used in the top 40 inches below proposed finish grade. | 4 | |
| 37 | Will erosion control matting (page 77 of 92, in plan set 124-175449, sub sheet no. 01-L501, detail 3/01-L501) be required on slopes made up of primarily lava rock and/or crushed lava rock? Normal this type of costly matting is unnecessary for such slopes and is extremely difficult to deploy properly when the slope is as rocky as is expected? Also, normally we would use a 10-mil thick polyethene sheeting surrounded by fiber logs and weighted with sandbags for temporary stockpiles, instead of erosion control matting? Is this approach acceptable for temporary stockpiles? | Matting would not be necessary on slopes made up of lava rock, but would be necessary on slopes with topsoil. These areas will be revegetated by the park and will require erosion control between the contractor replacing topsoil and when the park is able to plant. | 4 | |
| 38 | What types of backfill aggregates are available at the NPS quarry? If you do not have enough, will the contractor be allowed to excavate and crush the suitable backfill aggregates needed for the projects? If so, can the contractor extract and crush to manufacture the other aggregates needed for utility backfills, aggregate base course under pavements, and pathway surfacing? | Between the berm and quarry there is sufficient material to fill the Okamura building basement. The quarry has approximately 5,975 CY of material that can be used as fill at Uēkahuna Bluff. Regarding the questions related to excavating material at the quarry, the contractor may not excavate new material in the quarry. Only existing quarry stockpiled material may be used by the contractor. | 4 | |
| 39 | The NPS requires any/all outside aggregates hauled into the park from outside sources to be inspected; please provide an estimated time per load the inspection will take so we can determine an appropriate duration for each load? | 30 to 60 minutes depending on the number of vehicles present for inspection. The inspection site can accommodate up to 20 vehicles at a time. | 4 | |
| 40 | Detail 4/01-L501 on page 77 of 92, in plan set 124-175449, sub sheet no. 01-L501 it is noted that, “Mulch from outside the park shall not be permitted.” Will NPS be providing said mulch? If so, will the mulch be “ready to go” or will there be additional processing/mixing/augmentation needed to meet NPS standards? | The contractor is responsible for processing and placing the mulch per detail 4&5/01-L501. Per note 2 for Topsoil Replacement, mulch shall be sourced from on site. Mulch should be processed by the contractor from the green waste generated by clearing. Refer to Spec Section 01 74 19 - Construction Waste Management and Disposal for Green Waste procedures. | 4 | |
| 41 | Please be advised, the fiberglass epoxy conduits that are specified for above ground conduit runs are not moldable to follow the existing profile of the subject surface morphology. The fiberglass epoxy conduits need factory fittings to make any bends. Conduits will have some give being that they come in 20-foot lengths; but the manufacture will greatly limit such bends due the limitation of product strength and desired long-term performance. It is our opinion that the current planned profile does not consider the specified material’s design limitations as-well as the fiberoptic cable performance criteria such as the specified 2 90 TIA/EIA rule between boxes. If the straight sections of conduit can’t handle the planned vertical deviations and factory fittings are required; the number of fittings will jeopardize the specified 2 90 TIA/EIA rule between boxes. Please provide greater clarity and if needed please discuss with the design-engineer to see if they have coordinated with the manufacture of the conduit before planning the subject profile runs on this project?. | To be answered on next Amendment | ||
| 42 | Spec section 02 41 13 – 8 Para 3.7F. 4. a. 7) For bidding purposes does the National Park Service want to standardize bid quantity and anything above and beyond would be considered a change amount or provide a line-item fee for CY petroleum impacted soils? | If petroleum impacted soils are encountered, we will address in accordance with the contract's differing site conditions clause and via modification. | 4 | |
| 43 | Visitor center no longer being re-constructed verify coordination drawings on solicitation documents can be VE’ed out. | Coordination drawings for new VC are no longer required. | 4 | |
| 44 | Does NPS want a small business subcontracting plan if other small business subcontractors used. | NPS does not require a Small Business Plan (see Section L of the clauses for submission requirements), but one can be submitted as part of Factor 3, management approach. | 4 | |
| 45 | Per an onsite question could NPS provide an approximate amount of cy of material is available for use? | Question is unclear. Please clarify the material in question. | 4 | |
| 46 | Can a shared trailer be used with a private office for NPS or NPS prefers separate trailer? | Shared trailer with private, securable office is acceptable. | 4 | |
| 47 | Are the lights in the buildings to be demo’ed pcb containing ballasts or mercury bulbs? | Please refer to the Hazardous Materials Assessment Report provided with the solicitation. Approximately four hundred light fixtures were identified in the buildings. Ten representative light fixtures were examined. PCB ballasts were not identified in the fluorescent light fixtures examined. | 4 | |
| 48 | During the site visit it was mentioned that NPS will be clearing the vegetation from around the existing above ground water line path. Is NPS removing any trees as needed along the water line path too? | Yes | 4 | |
| 49 | How many weather days are allocated for this contract per month? | The contractor shall consider seasonal weather conditions in planning and scheduling work influenced by high and low ambient temperatures, wind, vog, or precipitation to ensure completion of work within contract time. | 4 | |
| 50 | Have the light ballasts been tested/verified for hazardous materials in buildings that are scheduled to be demolished? | Please refer to the Hazardous Materials Assessment Report provided with the solicitation. Approximately four hundred light fixtures were identified in the buildings. Ten representative light fixtures were examined. PCB ballasts were not identified in the fluorescent light fixtures examined. | 4 | |
| 51 | Has the existing electrical switch gear to be demolished been tested for hazardous materials? | Electrical switch gear was not tested. The contractor shall assume that any existing switchgears contain mercury. The Contractor shalll be responsible for handling, removal and disposal or recycling of the switchgears containing mercury. | 4 | |
| 52 | Can the existing building concrete be used as fill for the basement infill? | Existing building concrete can be used as fill for basement infill. Concrete meeting the particle size in specification 31 20 00 part 2.1.B. can be used as long as it not used in the top 40 inches below proposed finish grade. Concrete particles meeting the maximum particles size of 3 inches per specification 31 20 00 part 2.1.A.3. can be used with no depth restrictions. | 4 | |
| 53 | At the front entrance of the Jagger Building there are diamond steel covers on the floor. Is this a utility chase? What is in the chase? Have the existing materials in the chase been tested for hazardous materials? | The diamond plated steel plates are for the pex water supply system repair and old commutations between the main HVO building and the Annex building.
