BEGIN WITH

the end in mind

Our preconstruction team helps lay the foundation for a successful project by bringing together planning, collaboration, and cost certainty from the very beginning. 

Design-Assist & Planning

Detailed scheduling, budgeting and constructability reviews that keep projects aligned from day one.

Collaborative Partnerships

Working closely with owners, designers, vendors, subcontractors, and stakeholders to develop smart, efficient solutions.

Proactive Planning

Identifying challenges and opportunities early in the design phase to create a smoother project experience from concept to closeout.

ESTIMATING

Our estimating team helps set projects up for success by providing the insight, planning, and cost clarity needed to make confident decisions from the very beginning. Through conceptual budgeting, feasibility studies, constructability reviews, work package planning, and detailed scheduling, we work closely with project stakeholders to establish realistic expectations and align budgets with project goals. By combining proactive cost control, value engineering, best-value analysis, and transparent reporting with strong relationships across our vendor, supplier, and trade partner network, we help identify opportunities, manage risk, and deliver greater confidence throughout the planning process.

Our in-house electrical engineering team brings design and construction together from the very beginning, creating a more collaborative and efficient project experience. Working alongside our estimating, preconstruction, and field teams, our engineers develop practical solutions that improve constructability, support cost certainty, and keep projects moving forward. 

Using a Target Value Design approach, we evaluate options early and throughout the design process to keep budget, schedule, and performance aligned with your goals. The result is a smoother path from concept to completion, fewer surprises along the way, and greater value for your investment.

VIRTUAL DESIGN & CONSTRUCTION

Big State’s Virtual Design & Construction team brings together technology, planning, and hands-on field experience to help projects run smarter, safer, and more efficiently. Made up of experienced electricians, our team works closely with project stakeholders to improve coordination, solve challenges early, and keep projects moving smoothly from design through construction. 

As an industry leader in modeling and prefabrication, we invest in the latest tools and processes to support a LEAN approach from design through installation. By moving more work offsite, we’re able to improve quality, enhance safety, reduce waste, and keep projects running smoothly. We also have the ability to provide detailed product mockups that help clients visualize solutions, make confident decisions, and add real value before construction begins.
