We understand that the scheduled pre-bid site visit took place on August 11.

Unfortunately, we were unable to attend the scheduled visit. Would the Government be willing to allow a prospective contractor to conduct a brief site visit at a mutually convenient time? The purpose would simply be to observe the existing lift station and surrounding conditions so that our contractor can accurately evaluate the work and prepare a responsible quotation.

The Government is not able to support a second site visit at this time.

With the replacement of the control’s cabinet is it the intent to replace the visible electrical piping and recking material as well?

Yes
