Description

Oregon State University (OSU) issued a competitive one‑step RFP (2022‑007732) to retain a Construction Manager/General Contractor (CMGC) for the design‑build delivery of a new 4,500 sf research greenhouse and associated right‑of‑way (ROW) improvements on the Oak Creek campus. The scope includes demolition of existing raised‑bed structures, installation of a pre‑fabricated polycarbonate greenhouse supplied by Stonegate/Greenhouse Builders NW, site‑work (ADA‑accessible sidewalks, pedestrian lighting, street trees, concrete paving), and coordination of permits (building and PIPC). The contract is a CMGC arrangement with a GMP‑based fee structure; the agency intends to award the contract to Swinerton. Key deadlines were a mandatory pre‑proposal conference on 27 Jan 2022 and a proposal submission deadline of 8 Feb 2022. The project aims for greenhouse occupancy by 15 Jun 2022, with ROW work completing by the end of summer 2022. • Scope: greenhouse construction, demolition, site improvements, utility coordination, and compliance with OSU sustainability and safety policies. • Procurement: competitive one‑step RFP, full‑open competition, award to Swinerton (intent to award noted). • Schedule drivers: 12‑14 week greenhouse lead time, June 15 2022 occupancy target, no early excavation permit.

Contract value

$1,200,000

The greenhouse is 4,500 sf. Typical commercial greenhouse construction (polycarbonate panels, structural steel, foundations, MEP) in Oregon ranges from $180‑$250 per square foot when including design‑build management and site work. Using a midpoint of $215 sf yields roughly $967,500 for the greenhouse itself. Adding ROW improvements (sidewalks, lighting, trees, paving) and demolition could add $200 k‑$300 k. A reasonable ball‑park total contract value is therefore about $1.1 million to $1.3 million. Assuming a modest contingency and the CMGC fee, an estimate of $1.2 million is a defensible midpoint.
