Hazen and Sawyer

Hazen and Sawyer is a New York environmental engineering firm that does one thing at scale: water. Drinking water, wastewater, reuse, stormwater and water resources make up the whole practice, run from offices across the country. Right now it’s the city’s engineering consultant on Phase 1 of the Sioux City, Iowa, Wastewater Treatment Plant Facility Plan Improvements. Hazen reviewed the three hard bids and recommended awarding the base contract to PKG Contracting of Fargo, N.D., at $292.4 million, about 10% under the $325 million engineer’s estimate, while rejecting every alternate. That’s a good outcome for a city that walked away from its CMAR price. It’s also a decent sign the estimate was honest.
