Prepared by the Engineers Joint Contract Documents Committee (EJCDC).

C-522 is intended to be used for smaller, less complex projects, such as small water and wastewater utilities, roads and paving, drainage improvements, and site development.

The U.S. Department of Agriculture, Rural Utilities Service (RUS) has preapproved the use of certain standard EJCDC engineering and construction series documents for use in projects funded under the RUS Water and Waste Disposal program as described in RUS Bulletin 1780-26. Please note that Bulletin 1780-26 was updated on 5/10/24 to incorporate the use of C-522 under certain limited circumstances. EJCDC® recommends that C-522 be used only where the construction cost is $500,000 or less, and the scheduled duration is less than 12 months. However projects funded under the RUS Water and Waste Disposal program further limit the use of C-522 to contracts with costs at or below the Simplified Acquisition Threshold, which is currently $250,000.

EJCDC includes the American Society of Civil Engineers, the American Council of Engineering Companies, the National Society of Professional Engineers, and the participation of more than fifteen other professional engineering design, construction, owner, legal, and risk management organizations.

EJCDC documents are delivered in Microsoft Word format (file extension *.docx). Microsoft Word is required if you wish to edit the files.
