Are prime contractors to retain and include the cost of a VPIH in our proposals per 02 82 11 page 3? If so, can the VPIH and the CPIH be the same person?

See IMPORTANT NOTE in paragraph 1.1.2 C. of the referenced specification, and in the same location in spec 02 82 13.41 ASBESTOS ABATEMENT FOR TOTAL DEMOLITION PROJECTS. The VPIH shall be under the direct hire of the General Contractor. This responsibility to hire shall not be assigned to any sub-contractor, most particularly not to the asbestos abatement subcontractor. The VPIH may be either an employee of the General Contractor or may work for an independent firm sub-contracted by the General Contractor. It is not prohibited for the VPIH to also assume the duties and responsibilities of the CPIH if the General Contractor and the Asbestos Abatement Contractor agree to terms for this arrangement; however, the requirement stated in

1.1.2 C. shall govern, and the combined VPIH/CPIH shall be the direct hire of the General Contractor.

Do you have a plan holder’s list for the above referenced project you can send to me?

The process you are referring to is not applicable to Government contract bids, since plans are self-serve over the web.

We are a subcontractor for demo and were looking for a bidder list to contact for the Building Demo at the VA in Chillicothe, if you wouldn’t mind providing that.

Bidding for this project has been delayed due to current “social distancing” / health concerns.

Please check the solicitation for updates.

Looking for clarification if we’re to be mailing this bid or submitting electronically on the 14-May?

Please clarify.

Electronic bids will not be accepted at this time.
