Professional Engineering Services
Category Description
871 7 Construction Management and Engineering Consulting Services Related to Real Property Services provided under this SIN include construction management, engineering consulting, project management, and related professional services specifically pertaining to real property. The construction management approach utilizes one or more firms with construction, design, and management expertise to expand the customer agency's capabilities, so that the agency can successfully accomplish its program or project. The contractor performing construction management services assumes the position of professional adviser to the customer agency. Customer agencies may utilize the construction manager as the principal agent to advise or manage the process over the project regardless of the project delivery method used. Construction management services include, but are not limited to, design phase support, procurement support, commissioning services, testing services, construction claims support, and post-construction engineering services.

The contractor performing engineering consulting services functions as an advisor to the government to assist with executing engineering tasks associated with real property. Engineering consulting services relating to real property include, but are not limited to, mechanical engineering, electrical engineering, fire protection engineering, forensic engineering, structural engineering, or any other specialized engineering consulting services that are utilized in regards to real property. Authorized engineering consulting tasks include design reviews, shop drawing reviews, submittal reviews, inspection and testing services, witnessing acceptance tests of equipment and systems, commissioning, modeling and analysis, loss investigation, facility surveys, safety evaluations, research studies, risk mitigation strategy development or reviews, and other related technical consulting services. The contractor performing engineering consulting services shall not perform the construction of real property, nor be a named party under the construction contract. Project management services relating to a construction management or engineering consulting effort are authorized.

NOTE 1: This Schedule does not include Architect-Engineer services as defined in the Brooks Act, and does not include certification of designs or construction services as defined in the Federal Acquisition Regulation Part 36 and Part 2.

NOTE 2: This Schedule does not include Davis-Bacon Act work as described in Federal Acquisition Regulation Subpart 22.4.

NOTE 3: Some of the terminology used, such as professional engineer and design review, have multiple meanings in the engineering services profession. Under no circumstances should those terms be interpreted to include performance of Brooks Act services Section 1102 of 40 U.S.C. Chapter 11.
