Our Core

Let us show you why we are a valued partner in our Clients' success

W&A was established primarily to provide construction phase services. Our focus and expertise in this area is the true benefit of selecting our company for an assignment. Since we provide exclusively construction services, we are able to provide these services very cost effectively.


This singular focus allows us to focus on the relevant areas of training and employee development specific to our industry; this ultimately makes us more valuable to our clients.

Low Cost Structure


In times of increasing fiscal responsibility, both the public and private sector have been asked to reinvent themselves with a robust, cost effective approach to providing quality services and implementing capital programs for their citizens. Agencies must continually balance their decreasing revenue with the expenditures required to maintain a high quality of life for the people of our state.

W&A was founded to provide high quality, local expertise at a very cost-effective rate structure. We have been extremely successful in this approach with numerous cities and water districts in southern CA. Because of our low overhead and ability to streamline our operations, we can provide services at a significantly lower multiplier than our competitors. This also allows us to pay our team members higher wages and provide equal or better benefits than our competitors. In this way, we are assured to attract and retain the best team members for your projects.

Local Resources


We are centrally located in Corona for expedient coverage to all our Southern California clients. Our Project Managers, Construction Managers, Engineers and Inspectors can provide a wide array of technical expertise for our clients. Combined with our strong professional relationships with local survey, materials testing and design firms, we provide a full suite of Construction Management services. We currently provide full CM services to over 30 public agencies.

In addition to our full CM portfolio, we are only a phone call away to provide On-Call services to assist in all phases of the project development and implementation. Although we are a relatively small company, we have significant resources available throughout Southern California.
