RFP N62742-22-R-1322

PAF 198127 TACMOR UTILITIES AND

INFRASTRUCTURE SUPPORT

NOTE: The following questions and answers are provided for INFORMATION ONLY.

The RFP remains unchanged unless it is amended in writing on a Standard Form 30.

RESPONSES REVISED FROM NOTICE NO. 4

207. Reference: Notice 2 – Answers to Question 59 a & d indicate that Topographic surveys and soil boring logs of SD1 and SD2 are not available.

Question:

RFP specs - Figure 6 is provided as a Reference Images of the Proposed Soil Disposal

RFP specs - Figure 11 is provided Slope of access route to proposed SD 1. One-meter contours are extrapolated from the 1980 USGS topographic map and are not precise.

RFP specs - Figure 23 indicates Location of SD 2.

Based on the above provided information:

a. SD1: Total Area is approximately 10 Acres site, with elevation difference more than 60 ft North -> South. In order to utilize the SD 1 site as stockpile to accommodate all surplus basalt & soil, major site grading and retaining walls (60 ft tall) will be required to provide safe flat area for trucks to access the site. In order to avoid constructing costly retaining walls @ SD 1, please advise if the government is able to expand SD1 area to allow sloping / daylighting cut / fill to encroach into adjacent property to SD1?

Otherwise, we respectfully request the project design team to provide design for the SD1 site preparation including permanent structures (retaining walls), drainage..etc this is a design bid build solicitation and bidders are not responsible for design.

Please be advised, this is a major cost (millions of dollars) that all bidders shall include in the bid and more information is required from designers to avoid costly assumptions.

RESP: Contractor is responsible for disposal of all spoils. Contractor is not obligated to use soil disposal site 1 (SD1) or soil disposal site 2 (SD2). Bid per section 01 57 19 Temporary Environmental Controls.

b. Assuming that existing SD 1 is flat or the wining contractor will make it flat, based on volume of surplus materials and in order to provide safe access and safe stockpile plan, please be advised that 10 Acres Area is not sufficient to accommodate two separate stockpile (basalt & soil). Please advise if all bidders shall assume that the government will be able to expand SD1 area to accommodate ALL generated surplus materials. Please provide clear directions regarding this matter to allow all bidders to fairly price same conditions.

RESP: See response to RFI 207a

c. SD2: Total Area is approximately 5 Acres site, assuming that existing SD 2 is flat, please be advised that based on volume of surplus materials and in order to provide safe access and safe stockpile plan, the 5 Acres Area is not sufficient to accommodate two separate stockpile (basalt & soil). The 5 Acres SD 2 site will accommodate small portion of surplus basalt / soil which does not justify the cost to prepare access, BMPs, grading ..etc. Please advise if all bidders shall assume that the government will be able to expand SD2 area to accommodate ALL generated surplus materials. Please provide clear directions regarding this matter to allow all bidders to fairly price same conditions.

d. In case SD1 & SD2 are inadequate to accommodate stockpiles of surplus soil and basalt rock, will the contractor be entitled for price modification / change order?

Please provide clear directions regarding this matter to allow all bidders to fairly price same conditions.

78. Reference: SPEC SECTION 01 32 17.00 20 Page 10 - Subpart 1.10.2.8 Adverse Weather Lost Work Days – last paragraph reads: “The Contracting Officer will issue a modification in accordance with the contract clauses, giving the Contractor a time only extension for the difference of days between the anticipated and actual adverse weather delay if the number of actual adverse weather delay days exceeds the number of days anticipated for the month in which the delay occurs and the adverse weather delayed activities are on the longest path to contract completion in the period when delay occurred. A lost workday due to weather conditions is defined as a day in which the Contractor cannot work at least 50 percent of the day on the impacted activity. Make changes to P6 project calendars to reflect as-built conditions where work occurred where originally anticipated as non-work days, and where work did not occur (lost work day).”

Please clarify how will the stated 50% of the day be calculated? Does it mean one period of several hours rain or sum of interrupted hours at different times of work day?

RESP: The 50% criteria applies to both continuous weather delay (i.e. typhoon) or a series of start, stop interruptions (i.e. off & on rain shows/ thunderstorms) that prevent 50% performance (e.g. 4+ hours) on any original work activity scheduled for the authorized work period (e.g 8-hr day) on the date the weather event occurred. To be a weather delay, the weather event has to delay or prevent performance of at least 50% (4hrs) of work on any one original work activity scheduled for the authorized work period (8-hr day) on the date the weather event occurred.

If it is calculated based on sum of total interrupted hours at different times of work day, please be advised that due nature of this project (major earthwork and site concrete work) if the calculated 50% of rainy weather happens in different times of the day will lead to non-work day, because once crews commence working, prepare the site to recover from storm then another rain shower took place, crews have to stop before performing any work. However, if rain is continuous for 50% of work day (takes place in one continuous period) then contractor is able to get 50% of continuous ½ work day without interruption, in this case contractor’s crew can be to some extent productive.

RESP: See above response.

Accordingly, we respectfully request to add a clause in the spec to entitle the contractor to claim for weather lost work days if 50% of rainy weather in certain days took place during different times of work day.

RESP: Entitlement for delays due to adverse weather conditions will be handled in accordance with FAR 52.249-10, Default (Fixed Price Construction).

155. Dwg CE503/B4. Please provide locations of Diversion swale Type B shown on Detail B4/CE503.

RESP: Diversion swale Type B will be deleted. See forthcoming amendment.

196. Spec. Section 31 23 00.00 20, Para. 2.1.7. The Rx site geotechnical report does not provide Liquid Limit or Plastic Index values to determine if Select Fill can be found on site or not? Section 31 23 00.00 20, Para. 2.1.7 requires a Plasticity Index less 12 and a Liquid Limit less than 35 in accordance with ASTM D4318. Can the Government provide additional geotechnical data or is it the intention of the government is for this material to be imported? Please provide full geotechnical report for both the Tx and Rx sites.

RESP: See response to Question No. 210.

210. Specification section 31 23 00.00 20, paragraph 2.1.1. Specification section 31 23

00.00 20, paragraph 2.1.1 defines the satisfactory materials as GW, GM, GW-GM, SW, SM or SW-SM. The geotechnical analysis shows that these types of materials are not existent within the project boundaries. The required conforming material will need to be selected and transported from outside of the project site/Palau. Can you please confirm the in-situ material cannot be reused by the Contractor?

RESP: Yes, for the Tx site, the best data available indicates that the in-situ material is not suitable to be reused. See response to Question No. 191. For the Rx site, according to the best data available, the on-site coralline limestone may be processed (crushed, screened and blended) to meet the fill specifications, and can be used as part of the mass fill to finished subgrade elevations in accordance with subsection 3.6.2, Section 31 23 00.00 20. Fill must be free of unsatisfactory and unsuitable material and expansive soils. See response to Question Nos. 125 and 192.

233. Plan Sheet B701 – B75. Per the boring logs on Plan Sheets B701 – B706, dry density is provided in metric units (g/cm3), while sheets B707-B757 show imperial dry density units (lb/ft3). Dry density values provided on sheets B701-B706 are unreasonably high, as 45-60 g/cm3 is equivalent to 2800-3750 lb/ft3. Please confirm the correct values and units for the dry density.

RESP: B-701 to B-704, Dry Density: change g/cc to lb./cu. ft. See forthcoming amendment.

238. Specifications 03 30 00 Section 1.6.7.2 and 3.13. Please confirm that 3rd Party inspection company hired ACI Concrete Field Testing Technician Grade 1 as stated in

1.6.7.2 required during all testing mentioned in 3.13. Please also confirm, if there is no concrete there is no requirement of 3rd party qualified inspector to be on site.

RESP: Confirmed, an ACI Concrete Field Testing Technician must perform testing stated in paragraph 3.13. The Concrete Field Testing Technician is only needed on site for work on concrete.

246. Drawing CS501, Detail : B1. Referring to the non-metal bollard detail provided in drawing CS501 detail B1, please provide material requirements such as the type of the post, will government allow contractor to craft this type of bollard using the removed trees?

RESP: See response to Question No. 32. See forthcoming amendment.

250. Section 32 05 33, Para. 3.2.7. Section 32 05 33, Para. 3.2.7, Final Inspection and Acceptance, states the following: “Final inspection will be made upon written request from the Contractor at least 10 days prior to the last day of the turf establishment period.” As landscaping (at least for portions of the site) will be one of the final activities, this establishment period essential reduces the period of performance from 1106 calendar days to 741 calendar days, which does not seem realistic to complete all work required under this contract. Request that the contract duration be increased to account for this establishment period, or establishment period be reduced.

RESP: Turf establishment period will be reduced to 60 days. See forthcoming amendment.

252. The manufacturers for the crash rating are saying that they need to know what "M" or "K" crash rating is required for Palau Island project per ASTM F2656? That is the ASTM standard for crash rated fencing and gates.

RESP: Follow Section 32 31 13.53 and DWGS CF503-CF507, in order of precedence, for fence fabric reinforcement.

269. Notice No. 3, Pre-Proposal Questions & Answers, RFI #125. The Government’s response to RFI #125, a question regarding manufactured on-site fill at the Rx Site, stated the following: “Base bids on the assumption that the crushed/manufactured onsite soil is suitable to meet fill specifications. See forthcoming amendment.” Is it the Government’s intention to allow manufactured onsite material for only common and select fill, or is it the Government’s intention to allow for onsite material to be used to manufacture surfacing aggregate, pipe and trench bedding and backfill, and crushed aggregate base course?

RESP: Yes, for common fill only in accordance with Section 31 23 00.00 20, paragraph 3.6.2.

270. Notice No. 3, Pre-Proposal Questions & Answers, RFI #206. The Government’s response to RFI #206, a question regarding the use of locally available aggregate materials at the Tx Site, stated the following: “Base bids on using local aggregates.

Contractor shall be responsible to perform the required testing in accordance with the specifications. Should the aggregate be found to be unacceptable, it will be handled as a changed condition.” Please clarify how this will be applied by answering the following questions:

a. Does this only apply to inherent aggregate quality source tests such as Magnesium or Sodium Sulfate Soundness specifications, LA Abrasion specifications, Resistivity and PH specifications?

RESP: Contractor shall be responsible to perform the required testing in accordance with Section 35 42 34.

b. Does this changed condition also apply to aggregate tests that can be manipulated by means and methods? It is very likely that the local aggregate suppliers do not have the equipment or the willingness to meet the other required specifications, such as fracture specifications, fine angularity, gradations, flat and elongated particles, plasticity index specifications, or liquid limit specifications. Can the proposer use the list price of the local aggregates and expect to be able to use them without modification regardless of specification(s)?

RESP: For the aggregates specified in Section 32 12 16, the Contractor shall base their bid on locally available imported aggregate that meets requirements of Section 32 12 16.

NOTICE NO. 5 QUESTIONS AND ANSWERS CONTINUE

272. Follow up to notice 4, Q/A 167, On site generated fill materials. Please confirm than on-site materials at TX site is suitable for use as fill and that the government’s response to Q/A 167 only applies to SURPLAS quantities or Basalt rock & soil. If this not be the case and the on-site soil is not suitable as common fill then it, follows that all fill material will need to be imported: There is approx. 85,000 cy of general fill and select fill below pavements and approx. 33,000 cy of MSE materials required for the work with a conservative price tag of over $XXX mil.

Please provide guidance on the correct interpretation of the government’s response to Q/A 167.

RESP: See response to Question No. 210
