An Integral Partner

With the ability to manage projects of virtually any size, W.E. O’Neil provides a reliable management team, cost-saving initiatives, and time management capabilities for clients. Our experience allows our clients to, in effect, retain an in-house construction management team while remaining in the driver’s seat at all times. Acting on behalf of the client, we become the Owner’s agent liaison and project point of control.

It is our goal to become an integral partner in achieving a successful project.

Time is Money - Experience Saves Both

Always cost-conscious, W.E. O’Neil can invest significant time and effort to explore available value options to help reduce construction costs. Our objective is to provide viable, cost-effective alternatives, allowing our clients to make the decisions that are in their best interest.

Working closely with the client’s project team of architects and engineers, we assist the project designers in choosing the most cost-effective course of construction while helping to maintain the essential character of a project. This enables each client to maintain the design intent of their project while reducing costs and maintaining efficiencies.


The team at W.E. O’Neil were professional and a pleasure to work with. The overall GMP process (which was open book and completely transparent) was a great asset as it allowed our team to properly manage the project on a financial basis. I highly recommend them as a partner when building Self Storage projects.

I have relied on W.E. O’Neil for many years on many projects totaling millions of dollars in construction and have always been more than pleased with their performance. Their team is easy to work with, listens well to challenges, and finishes their project on time and within budget.

One of their great strengths is communication and ensuring the project scope is well understood before initiating construction. I highly recommend them for consideration of any project size and complexity.
