Willdan Group, Inc. (“Willdan”) (NASDAQ:WLDN) today announced that its wholly-owned subsidiary, Willdan Engineering, was awarded a significant new contract with the City of Elk Grove, a community of more than 140,000 residents located near Sacramento, California, to provide the City’s Public Works services. The contract will commence January 1, 2011. The contract has a three-year base with three optional one-year extensions. Richard W. Shepard, Elk Grove’s Public Works Director, remarked that the new outsourcing contract with Willdan is expected to bring significant cost savings to the City which will allow for improved services. The City, which outsources a number of municipal services, selected Willdan for its depth of experience and cost efficiency. Where previously the City hired multiple firms to provide services, the City Council opted to consolidate all Public Works services under a single contract with Willdan. The services that Willdan will provide encompass three major areas—city engineering services, capital improvements, and operations and maintenance—including repair and improvements to city streets and lighting and drainage systems. Willdan will retain up to 40 employees from a previous service provider that worked for the City, as well as manage a group of subcontractors and subconsultants. Daniel Chow, Willdan Engineering’s Chief Executive Officer, remarked, “Willdan is pleased to have the opportunity to serve the City of Elk Grove and its residents by providing exemplary services to the Public Works Department.” “The outsourcing model that the City of Elk Grove has chosen, with senior city management staff oversight, can serve as a model that other municipalities may choose to adopt in order to optimize efficiency, enhance customer service, and minimize costs to their residents,” Mr. Chow added.
