Requirements

160 Per response to PPI #29 included as part of Amendment No. 9, required occupant load to be supported for P1533 PMO is 348 occupants. Per

ICC 500

requirements, community shelters for hurricanes require a space for 20 sq.ft.

per occupant. For the PMO facility, accommodations for 348 occupants would then require a minimum usable floor area of 6,960 sq.

ft. (with no increase included for use or furniture type). This designated area comprises a significant portion of the overall facility. Our understanding of the 348 occupancy load for this building is that it would also include transient visitors and personnel who are present for

Occupant load for hurricane shelter shall be 248 persons.

training. During a hurricane event, it is presumed that visitors will not be allowed, training will not continue, thus such spaces to shelter these occupants would not apply. It may also be logical to assume a substantial reduction in permanent staff members for the duration of a hurricane. As a comparison, the occupant loads associated with the two fire stations that are part of Package 5 seem logical and reasonable and reflect a fraction of the total occupancy. Please confirm if it is the government’s intent to provide a shelter for such a high number of occupants for the P1533 PMO facility.

185 Amendment 0005 Bid Form

All CLIN 0005AC, 0006AC & 0007AC all say complete work for the facility inside the 5' line. This is the same description as

CLIN 0005AB,

0006AB & 0007AB.

Please confirm CLIN

0005AC, 0006AC &

0007AC should all say complete work for the facility outside the 5' line.

5AC, 6AC and 7AC should read "outside". See

Amendment 0014 for revised Price Proposal Form.

186 Amendment 0005 Bid Form

All The bid form requires soil samplings for Total Petroleum Hydrocarbons (TPH) diesel range and gasoline range organics (DRO & GRO), and Benzene, Toluene, Bid per RFP.

187 Part 6 Attachment B.9

P1203 & P1518

Attachment B.9 states that there was a suspected PFAS release and recommends a site invistigation at Building 18 (Hadnot Point Fire Station) and Building BB8 (Courthouse Bay Fire Station). Plese confirm that only a site investigation is required as part of the construction contract and that if PFAS is present and requires remediation it will be considered a changed condition. Please provide the required criteria for a site investigation (what contamanents should be tested for, # of samples, etc...).

Yes, bid per RFP.

188 Part 6 - Attachment B.8

P1312 Scope indicates a full archaeological report would be submitted (following current OSA reporting requirements). Would a full archaeological report be required if no cultural features are recorded or can an executive summary suffice?

Per current OSA reporting requirements, a full report will be required. If no features are found, there would be less info to report, but standard report format needs to be adhered to.

189 Part 6 - Attachment B.8

P1312 Can you please confirm that monitoring is for the purposes of recording intact archaeological features and human remains, not general artifact collection from the site (Section IIB: “…archaeologist shall record and be authorized to collect archaeological material as warranted for analysis”)?

If intact features are located within areas that would be disturbed during demolition, feature excavation and collection of artifacts for analysis from the features would be required. General artifact collection should be limited to minimum required by OSA reporting requirements. Sample size to be determined by archaeological field director based on OSA requirements. If human remains are encountered, all work in vicinity stops and OSA must be notified for consulting on treatment/recovery plan. Human remains may require excavation for standard analysis if avoidance is not feasible.

190 Part 6 - Attachment B.8

P1312 Under Section IIA:

“archaeologist shall be present…until it is determined that project construction activities could have no effects on significant archaeological resources.”

Determined by whom? The archaeological monitor? The base archaeologist?

Determined by archaeological project manager, Base Archaeologist, and the demolition contract manager through review of demo plans detailing level and extent of ground disturbance.

191 Part 6 - Attachment B.8

P1312 For intact non-burial features: “…the archaeologist shall, after making a reasonable effort to assess the identity, integrity, and significance of the encountered archaeological resource, present the findings of this assessment to PWD and ECON”. In this case, what constitutes

Burial features may not be evident from surface stain or artifact/shell concentrations on the surface until a feature is bisected. For intact non-posthole features- present findings to Base Archaeologist, record, map and bisect all non-posthole features; record and map all posthole features, but bisect only a representative sample of post-like features. If human remains are discovered during feature reasonable? Bisect each feature?

Although unlikely (given the previous disturbance in the area) what if multiple posthole features are recorded? Can a representative sample be recorded/excavated?

bisection excavations or noted at feature surface, stop work and consult with Base

Archaeologist and OSA.

192 Part 6 - Attachment B.8

P1312 The scope indicates that the archaeologist must be Secretary of Interior (SOI) qualified. If human remains and/or larger cultural features are encountered that need to be recorded and excavated, can we bring in additional archaeologists to assist? Can the scope be amended to “It is mandated that the supervising archaeologist hired meets the standards of the Secretary of the Interior…”?

Yes, and yes.

193 Part 6 - Attachment B.8

P1312 Can you please confirm that the scope of work does not include costs associated with the excavation of human remains (would need to scope separately/issue a change order) and that no skeletal analysis is included as part of this project (recovery only)?

The scope of work does not include costs associated with the excavation of human remains and no skeletal analysis is included as part of this project.

194 Part 6 - Attachment B.8

P1312 Can we put a limit to the number/types of materials collected and the level of analysis? For example: no collection of cultural materials from the general surface or disturbed soils and analysis limited to a representative sample of culturally diagnostic artifacts from excavated features.

No collection of cultural materials from the general surface or disturbed soils and analysis limited to a representative sample of culturally diagnostic artifacts from excavated features.

195 Attachment F All The bid form has individual CLINs for each project to Undercut of Geotechnically Unsuitable Subgrade Soils and Replacement with Imported Structural Fill material. Part

3.1.3.1 there are criteria for bidding that include removal of uncontrolled fill, over excavation at the parking lots, etc...

Please clarify if the Contractors are to include removal and replacement of unsuitable material in their proposal in addition to the unit prices required or are the unit prices intended to cover all removal and replacement of unsuitable material.

The removal and replacement of the uncontrolled fill materials noted in the Criteria for Bidding is included in the quantity provided in the Price
