Cahill’s seasoned team of preconstruction executives and estimators assists clients and design teams with preconstruction services, from the earliest stages of project visioning to assembling final bids and contracts. We strongly believe that our involvement early in the preconstruction process is invaluable to delivering a high quality project and reducing overall project cost.



Cahill can develop cost estimates from conceptual designs to 100% Construction Documents. With over a century of experience, we have developed an extensive database and corporate memory to draw from. In addition, our subcontractor network and self-perform work keeps our finger on the pulse of current costs. As a local company, we are familiar with the unique requirements and current pricing for work on all sides of the Bay. 

Value Engineering

With our detailed estimates as a launching point, Cahill leverages experience, scenario analysis, and creativity to help clients identify and evaluate tradeoffs in design, materials, and construction phasing. This is how we ensure that each client receives the best value, meeting or exceeding project goals while staying within our client’s budget.

Constructability Reviews

Early review of drawings helps identify potential problems prior to the start of construction. Cahill involves experienced superintendents in evaluating complex scenarios, leveraging their building expertise and field perspective to resolve issues and avoid cost or schedule impacts.

Site Logistics Planning

Cahill has experience working on all types of project sites, including urban infill projects, steep hillsides, and occupied buildings. We take our clients’ needs into account to map out a plan that ensures that construction is completed safely, efficiently, and with minimal inconvenience for all involved.  

Design Build

Design Build projects allow Cahill the opportunity to drive the design process to best meet the client’s needs. Using our specialized knowledge, we can steer the design to shorten project durations, identify and resolve problems prior to construction, and transition into a smooth construction process. Cahill has deep experience spearheading design-build MEPS scopes of work and has conducted comprehensive design-build project delivery on numerous tenant improvement projects.
