Does the Government have an estimated construction magnitude, budget range, or independent cost estimate for this project?

No. Per FAR Overhaul, FAR 36.204 Disclosure of the magnitude of construction projects is no longer relevant.

https://www.acquisition.gov/far-overhaul/far-part-deviation-guide/far-overhaul-part-36

Please confirm whether all structural-backfill testing requirements, lift thicknesses, moisture requirements, compaction standards, and acceptance criteria are contained in the referenced drawings and specifications.

See page 7 of drawings, Drawing # 732721-020-M-CON-B, sheet 2&3 and FSSS 208, Structural excavation and backfill for select major structures. Aslo see section 208 of the FP-24, table 208-1 for testing requirements.

Will dewatering, water diversion, bypass pumping, or temporary stream-control measures be required during construction?

It is the contractors responsibility to come up with a safe workplan for executing the project. It depends on the time of the year. If work starts in the fall there may not be a need for dewatering while building the multi-plate.

Are reinforcing steel, forms, concrete embeds, and other materials required for the two concrete collars contractor-furnished, except for the Government-furnished hook bolts? Yes, that is correct.

Will Contech Engineered Solutions or a Government technical representative provide on-site guidance during assembly of the Government-furnished multi-plate culvert components, or is the contractor solely responsible for assembly and installation?

The contractor is solely responsible for assembly and installation of the multi-plate culvert components. Manufacturers instructions are included in the FS Special Specifications and Drawings.

The pre-quote road-use permit authorizes one pickup vehicle to the designated turnaround area. After award, will heavy construction equipment, haul trucks, concrete trucks, and material-delivery vehicles be permitted to access the project site? Yes, ther is limited space however

If access or construction is suspended because of fire restrictions, adverse weather, or Government-directed road closures, will the 90-calendar-day performance period be extended through an equitable time adjustment? Yes, a no cost-time extension will be negotiated.

May the prime offeror rely on and submit the relevant past performance, personnel qualifications, and technical experience of a proposed subcontractor as part of its quotation? No, past performance must be from the offeror submitting the quote

Please confirm how FAR 52.219-14, Limitations on Subcontracting, will be applied to this construction requirement, including the percentage of performance that must be completed by the prime and similarly situated small-business subcontractors. FAR 52.219-14(e)(3) applies

No, as long as any work hours that fall outside of normal work hours are coordinated with the Contracting Officer.

Yes, the contractor is Quality Control, the Govt. is Quality Assurance.

It is the intent of the Govt. to start the project this fall and take advantage of the low stream flows, however if an early winter hits the project will need to have a Stop Work Winter Shutdown until Spring.

Is there a range of engineered estimate for this project? No. Per FAR Overhaul, FAR 36.204 Disclosure of the magnitude of construction projects is no longer relevant.
