New Construction

Structural Design for new buildings represents the Lion’s share of BTI’s projects. In our 37+ year history, we have completed many large projects, from state of the art fulfillment centers, to university buildings, freezers, medical office buildings, warehouses, industrial buildings, big retail, and more. We provide services from conceptual design through construction administration. We completed those projects with creativity in choosing the appropriate structural system, responsiveness to team members during all stages of the project and strong focus on clients’ goals and budget.

Due Diligence

Our expertise and full-scope of services allows us to assist clients from initial Seismic Risk Assessments, to in depth investigations involving complex computer analysis, and, when required, full Seismic Retrofit analysis and Construction Support services. We successfully assisted many of our clients in their building acquisition due diligence process by providing them with reports describing the conditions of the structural system of the buildings at time of purchase. We also provided them with PML (Probable Maximum Loss) / SUL (Scenario Upper Limit) to help them manage their risk.

Seismic Retrofit

At BTI, making buildings safe is an important part of our mission. We have retrofitted and upgraded hundreds of buildings since we started. We specialize in upgrading of industrial and warehouse buildings including tilt-up, CMU and steel buildings. We keep in mind the cost and the fact that some of these buildings must remain functional during the upgrade process.
