Dealing with Planners

“We need to figure out how to convince Planning that they can’t take six months to plan a nine month project.”

Pete Raschio, BPA

What should the Planners give you?

Solicitation for Bids

Data

Bidder’s List

Draft solicitation to potential bidders for comment

Cost saving suggestions from suppliers

Bidding period at least 120 days

Timing: How busy are the manufacturers?

Spare Parts – How to specify?

Warranty: RAM-is it worth it?

Specification Detailed vs. Performance

Second source for thyristors?

Schedule – Liquidated damages

Scope

Retain construction activities

Lots of arguments

Standards: IEC, IEEE, ASME, ASCE

RAM Guarantee Reliability – Outages

Availability - % Useful Time

Maintainability

Staff hours to maintain

Elaborate record keeping

Costly for both sides

Bidding
