Attachment C – Responses to RFI

1. Contract duration is 300 ccd. Per manufacturers, the drawing submittals take 8-10 weeks, and the pump fabrications and controls take 40 weeks after approval. Assuming approval is given on the 1st round, the shipment will be made to the site almost 380 days later figuring one month of review time. We require minimum six months for demolition, installation, start up and testing after receiving shipment. Please revise the time duration to a reasonable time frame of560ccd.

Contractor to seek alternate pump mnf. Contractor provides any options that would reduce the lead time.

2. The specifications calls for skid mounted pumping system assembled and shop tested in the manufacture’s shop.

The drawing shows otherwise. Meaning pumps, valves, headers assembled in the field by the contractor and piped

up. Should we follow the drawing since the manufacturer states shop assembly as shown is not practical.

The field assembly and testing of the pumps/piping is acceptable.

3. In the Amendment responses, including the recently issued Amendment 06 for 36C24224B0026 Replace Pump Station & Controls VA ST Albans, you identified the handling of rock excavation and dewatering to be the responsibility of contractor, however, you did not provide a geotechnical report for use by the bidders. Since we are bidding this without a geotechnical report, please create an allowance value on the bid form to cover the cost of rock excavation and dewatering costs so that all bidders can bid with a fair comparison between the contractors.

The Contractor shall include allowance of $5000 per manhole for unforeseen conditions (dewatering, rock, other structures, etc.) along the site communication routing and manholes.
