What is being bought

Published requirement description

The Crown Estate (TCE) is seeking to establish a contract with a single supplier to provide specific services to support the delivery of Ecological surveys for the next offshore wind leasing round.

The purpose of this tender is to provide TCE with an efficient way to call off future requirements for Ecological services. This will avoid individual tenders being issued as required and Tenderers having to invest time in bidding for multiple tenders.

When the contract is let to a single supplier, Individual Work Orders will be issued using structured call offs, with each detailing the specific scope, activities, deliverables and timelines.

What this means for your bid

Price carries 25 of 100 points: a 10% discount moves about 2.5 points. The method statement decides this lot, not the discount.
“Ecological Surveys Advisor ITT” is a framework: the contest is a place on its panel, up to 1 suppliers, not a single contract, and call-offs are awarded directly: getting appointed is the whole game.

Price arithmetic assumes straight proportional scoring; the tender pack may use another formula.
