• The construction methods are determined by the contractor. The alternative method of mounting or breakers are to be determined by the contractor.

• Where can specifications for the new Distribution Board, Panelboard and Transformer be found.

• The electrical component details can be found in the drawings and specifications. The distribution board and panelboard can be found in these documents. The transformer for the electrical pole is handled by the local utility company. The Contractor is responsible for communication, logistics, and any cost associated with upgrading a transformer.

• Bid Schedule indicates for bid item 13 Division 28, the Table of Contents indicates not used, assumption this should be Division 40

• Correct

• Section L Factor 3 requests Past Performance. Is a Past performance questionnaire acceptable.

And if so, would FWS be able to provide the requisite form? Also are CPARS acceptable.

• There is no need to provide CPARS information, as this information will be gathered and reviewed internally for the responsibility determination.

• The bid schedule lists Division 2: Radon Mitigation, however, there is no Division 2 in the specifications. Is this bid schedule item no longer relevant as the radon fans are included in Division 23?

• The project still requires radon mitigation. Please submit the price to the bid schedule Division 2 knowing that the work is called out in a different division.
