Number Question Answer

Are there any American Iron and Steel or Build America, Buy America regulations for this project?

Contractors should review the provisions and clauses.

One-piece or two-piece shaft is acceptable. On-site replaceable seal is required.

3 Dezurik doesn't make a double offset butterfly valve Double-offset design required.

Stayflow isn't NSF certified to my knowledge, is that a requirement on this project? This is our first time hearing of this company, do you have any references for them?

NSF certification is not required

Clarify if it is electronic submission or in-person bid delivery to Reston, VA office

No liquidated damages clause is included in this contract. The Government retains its right to actual damages in the event of contract breach.

What are TERO requirements if any (taxes, employment of locals etc.)?

Special attention is called to FAR Clause 52.236-7, Permits and Responsibilities and FAR Clause 52.229-3, Federal, State, and Local Taxes.

There are no specifications for these roles. It is the responsiblity of the contractor to provide personnel who are qualified and experienced for their roles. The Site Superintendent, Site Safety and Heath Officer, and Quality Control Manager shall all be diffferent people. No dual- hatting will be permitted.

Spec 02 26 00 assumes presence of both lead-based paint and asbestos-containing materials. Since RFP didn’t provide the hazmat survey, how do you wish the contractor to proceed? Should we include the hazmat survey cost in the proposal and removal and disposal of all hazmat will be a change order or BIA will provide the bid allowances for all offerors?

Include hazmat survey costs to determine appropriate protection of employees from hazards in accordance with OSHA standards for construction for asbestos and lead-based paint provided within Section 02 26 00 - Hazard Materials Assessment. If found necessary for removal and disposal, notify BIA.
