EJCDC’s E‑500 is typically used to engage an engineer’s services for a single, specific project. It is drafted for the design-bid-build project delivery system. With minor revisions, it is appropriate for design-negotiate-build project delivery, and can be adapted easily to use in contracting for primary professional services on a variety of other project delivery systems.
Project owners and engineering firms have relied on E-500’s overall content, risk allocations, and philosophical approach over the years. The 2020 edition remains consistent with prior standards. In addition, the 2020 E-500 Agreement contains focused improvements, more options, better guidance and instructions, and an improved structure.
