Diversified Project Management Inc. of Newton has been retained by the Holyoke Public Library to manage the design and construction to expand the building, which includes restoring the structure.

The library has been working to obtain a grant from the Massachusetts Board of Library Commissioners to assist with the cost of expanding the facility to include nearly 40,000 square feet, while preserving and restoring a large portion of the original structure. A construction grant application was accepted by the Commissioners on July 7, 2005 and a provisional grant was awarded on Aug. 14, 2008 for $4.4 million.

The project is expected to cost between $14 million and $17.5 million.

DPM will provide full project management services including the management of the budget, scope and schedule, bidding and the selection of consultants and the vendors including the general contractor or construction manager.

"It’s a thrill to be a part of a project that will combine the best of the last century with a facility that will reach far into the future with technology, information and education. We’re honored to be serving," said Frank Kennedy, who is leading the DPM effort serving as the project executive.
