Seattle Biotech and Life Sciences General Contractor
Seattle is one of the top life sciences markets in the country, anchored by Fred Hutch, UW Medicine, the Allen Institute, and a dense cluster of biotech companies in South Lake Union and along the I-5 corridor. Research-grade construction here is exacting: precise airflow, containment, redundancy, and vibration control are not optional, and the cost of getting them wrong is measured in ruined experiments and failed inspections.
TCG delivers design-build life sciences construction with in-house MEP engineering, structural engineering, and architecture. We build BSL-1 and BSL-2 labs, cleanrooms, vivariums, and GMP space, and self-perform the specialty flooring (ESD, seamless resinous) that lab and clean environments require. See our national life sciences practice.
How Much Does Lab Construction Cost in Seattle?
Seattle life sciences construction carries a premium over standard commercial work because of intensive mechanical systems, containment, and redundancy, layered on top of the region's prevailing wage and seismic costs. Lab fit-outs in particular are mechanical-dominated budgets.
| Project Type | Seattle Cost Range |
|---|---|
| Office to lab conversion (TI) | $230-$580/SF |
| Wet lab (BSL-1/BSL-2) | $400-$750/SF |
| Cleanroom (ISO 7/8) | $500-$1,100/SF |
| GMP manufacturing space | $600-$1,200/SF |
| Vivarium | $550-$1,000/SF |
Mechanical, electrical, and plumbing routinely make up 45 to 60% of a lab budget. Early MEP design is where the savings live. Use our AI estimator above or schedule a call.
Why TCG for Seattle Life Sciences
Lab construction is an MEP problem first and a building problem second, and TCG keeps that engineering in-house. Our MEP team designs the 100% outside-air systems, pressure cascades, and redundancy that containment and cleanroom work demand, and our structural engineers address both Seismic Design Category D and the vibration control that sensitive instruments require.
Because design and construction sit under one design-build contract, we catch the conflicts between architecture, structure, and mechanical before they reach the field, where they would otherwise become expensive change orders. We also self-perform the ESD and seamless resinous flooring that lab environments need, removing a common schedule bottleneck.
Seattle Life Sciences Construction FAQ
Common questions about life sciences and lab construction in the Puget Sound region. See our full FAQ page for more.
Seattle lab construction ranges from $230-$580/SF for an office-to-lab TI, $400-$750/SF for a BSL wet lab, $500-$1,100/SF for an ISO cleanroom, and $600-$1,200/SF for GMP space. Mechanical systems drive the budget.
Seattle is anchored by Fred Hutch, UW Medicine, the Allen Institute, and a dense biotech cluster in South Lake Union. This concentration of research institutions and companies makes it one of the top life sciences markets in the country.
Mechanical, electrical, and plumbing typically make up 45 to 60% of a lab budget due to 100% outside-air systems, pressure control, exhaust, and redundancy. This is why early MEP design is the most important cost lever.
Yes. TCG provides in-house MEP engineering, which is critical for labs where airflow, containment, and redundancy define the project. Keeping MEP in-house under a design-build contract prevents the coordination failures that drive change orders.
Labs in Seattle must meet Seismic Design Category D, including equipment anchorage and, for sensitive instruments, vibration control. TCG's structural engineers design for both seismic performance and vibration on every lab project.
Yes. TCG builds ISO cleanrooms, BSL-1 and BSL-2 labs, vivariums, and GMP manufacturing space, and self-performs ESD and seamless resinous flooring required in these environments.
