ProWest Constructors Case Study

How ProWest Constructors cut its estimating time by 50% — with Provision

The Challenge

Scoping was slow, manual, and a costly source of risk

ProWest Constructors is a California general contractor with more than 31 years of experience, specializing in public-sector projects, including K-12 schools, community colleges, universities, civic facilities, affordable housing, and healthcare. Founded as a construction management firm, the company transitioned to a bidding general contractor model about 25 years ago and today primarily delivers at-risk GC, design-build, and California lease-leaseback projects.

On an at-risk job, scope is where money is won or lost. ProWest’s previous process was costly and labor intensive.

Manual review

Manual review of specs and plan sets required substantial time and effort, impacting efficiency and scalability.

Off the bid clock

The short bidding window meant that deeper scope investigation frequently carried into the post-award phase.

Inconsistent

Part art, part science. Estimating relied heavily on the judgment and experience of each estimator.

Scope gaps

When scope ownership isn’t clearly defined, questions can persist throughout the life of a project, from mobilization through closeout.

“Disputes start when scopes are unclear and often continue long after the job is finished. Successful projects begin with clearly defined scopes before anyone breaks ground.”

— Michael DeMarie, President, ProWest Constructors

The Solution

Why ProWest turned to Provision

Michael found Provision while researching vendors for an industry conference. Intrigued by AI-driven scoping, he reached out, and instead of starting with a demo, the team put the platform to work on a live project:

Built for scoping. Provision identifies trade packages and surfaces scope straight from the specs and drawings.

Tested on a live bid. The first test was on an active project, where a senior estimator was already developing the scope while the team was balancing a demanding workload and limited resources.

Paid back immediately. It saved days on that first project and surfaced items the team had missed.

“It saved an estimated three to four days on a project of that size. The speed and level of detail were impressive, and it helped identify several items that might otherwise have been missed.”

ProWest’s New Process

Scoping as a fast, repeatable system

Provision now runs at the front of the scoping workflow, giving the team a consistent starting point on every project:

Runs the initial scope in a fraction of the time. Trade packages and scope are surfaced automatically, so the data is there without a page-by-page read.

Follows one shared protocol. A repeatable process replaces individual styles, giving a true standard operating procedure.

Catches costly, easy-to-miss items. On a library renovation, a seismic upgrade required shoring that was buried in an obscure note. Provision flagged it before the team reached it on their own checklist.

Works for the whole team. Veterans expected to resist were the most impressed. Younger, tech-savvy estimators took to it naturally.

“Experienced estimators know that critical scope requirements are sometimes hidden deep within the documentation. In this case, Provision surfaced a shoring requirement buried in an obscure note and ensured it was captured during the review process.”

Their ROI

Speeding up estimating, catching misses, and adding capacity

What ProWest has seen with Provision:

~50% less time on the scoping and estimating work behind each project.

3 to 4 days saved on the very first project scoped with Provision.

Several scope gaps identified on that same initial project.

For a bidding GC, the real prize is capacity. Bid opportunities are difficult to predict, and busy periods often force a trade-off between pursuing more work and thoroughly scoping it. With Provision, ProWest sees a path to achieving its growth goals without significantly expanding the estimating department.

“Provision has been a great value for ProWest, and I’m excited about where the partnership is headed. The team’s dedication to continuously improving the product and adapting it to our needs has helped us save time and work more efficiently.”
