This month’s B2B focuses on the conversion of an existing 1 million-square-foot commercial office building’s record computer-aided drawings (CAD) to building information modeling (BIM) drawings. The original CAD drawings were produced in the late 1980s, and the building’s shell and core was constructed between 1989 and 1991 with ongoing tenant fit-out, though well-documented record drawings of the tenant space are lacking.
At the recommendation of the owner representative consultant to the building owner, the project delivery method shall be integrated project delivery (IPD), referencing 2019 ASHRAE Handbook – HVAC Applications, Chapter 59, Integrated Building Design, as well as Chapter 3, Commercial and Public Buildings. The IPD team shall include the building owner’s office manager; the building facility manager; a third-party owner representative to facilitate the project; a commissioning agent; the architectural, structural, HVAC, plumbing, electrical, and security contractors; a communications technician; and a general contractor.
