The document is a reference form for bidders participating in a Job Order Contract (JOC) for General Construction. The form requires bidders to provide project references, including client names, contacts, project descriptions, and the value of work self-performed. Bidders are also asked to explain their approach to complying with the requirement to self-perform 25% of the work. The document also includes a rider clause regarding the use of the contract by members of the Northern Virginia Cooperative Purchasing Council and the Metropolitan Washington Council of Governments. The clause allows the successful vendor to offer the goods and services of the bid to other member jurisdictions, but participation is voluntary for both the bidder and the member jurisdictions. The document includes a list of member jurisdictions and requires the awarded vendor to notify them of the availability of the contract. It is mentioned that the vendor will utilize proprietary licensed documents and software provided by a consulting contract with Loudoun County, and any member jurisdictions utilizing the vendor will be liable for the licensing fee.
