1 TOA PG. 3 RFP Part 1 PoP

The current period of performance of 389 calendar days will not be adequate to satisfy the Government’s design submittal requirements, manage the procurement of long lead items and perform the construction works. To mitigate this risk to the Government, and to enable the offeror to complete the design and construction in accordance with the Government requirements, will the Government please consider increasing the overall period of performance to a minimum of 831 calendar days?

The period of performace has been extended to 783 days. 6/21/24 8/7/2024 Amenment

2 Contracting Task Order Announcement

Subcontractors and suppliers have notified us that preparations of quotations for this Design-Build project will take more time than projects that are already fully designed. Information obtained from the site visit last week is being analyzed and incorporated into project narratives and estimates. Please consider extending the proposal due date by two weeks to allow for development and submission of accurate and cost competitive proposals.

Original proposal due date was extended to 9 August 2024. Please monitor SAM.gov and email for amendments to orignal solicitation. 7/16/24 7/30/2024 Amenment

3 Contracting Task Order Announcement

The Contract performance period is identified as 389 calendar days.

This performance period is insufficient for a Design-Build project with significant long lead equipment such as transformers and generators.

Assuming nine months for design, 12 months for long lead equipment, and six months for contract completion beyond delivery of long lead equipment, please revise the contract performance period to 27 months / 821 calendar days.

The period of performace has been extended to 783 days. 7/16/24 8/7/2024 Amenment

4 Electrical E-601 For reconnection purposes, please provide the size/description of the existing electrical feeders (Sheet Key Note #2) that runs from SU-1 & SU-2 up to existing Pad Mounted Transformers (Housing Cluster)

Exisiting sizes will need to be investigated by the design builld contractor. A separate site visit can be arranged to confirm this information. 7/16/24 7/30/2024 Amenment

5 Electrical E-606 Is the Contractor required to conduct elecrical testing on the existing primary feeders (that will be reconnected) running from SU-1 & SU-2 up to the new Pad Mounted Transformers? Please advise.

No, testing the existing cables is not part of the scope, however this was discussed with the Government during RFP document phase. "High Pot" testing may damage the existing cables. IF the DB believes cables should be tested this will require further disucssions with the government.
