We leave nothing to chance.


Haskell pioneered the design-build model more than 50 years ago and brought it to its rightful place within the AEC industry. We embraced our core strength and built upon it to serve as a trusted advisor to our clients in a manner that generates the greatest return on investment.

We believe in putting clients first, listening generously to understand their distinct situation, and responding with innovative solutions that emanate from their point of view.

Our breadth of expertise generates the certainty of outcome and minimization of risk demanded in today’s complex economy.

Success ultimately depends on the ability to effectively execute projects and control outcomes.

Others deliver projects, we transform environments.

This was a major $45 million project that included construction of 3 new digesters, gas collection system, FOG receiving station, co-generation facility and blower/aeration system enhancements. The professionalism and dedication of your construction team has resulted in a project that FWSA is very proud of and will provide energy savings for decades to come.
