Waltham, Massachusetts

Class ‘AA’ Corporate Headquarter Office Campus – phased new construction at former VERIZON Property 



Project:       This 312,000 square foot three story headquarters building meeting achieved LEED GOLD Certification as to energy conservation requirements and a supporting new 420 space parking structure is part of an overall new corporate campus development.

GDHarley-Services:    GDHarley & Associates represented the equity investor – Prudential Real Estate Investors, working with its local Developer Partners / Davis Marcus Partners providing due diligence services and review of the proposed architectural designs prior to the loan closing; during following construction phase we provided monthly construction inspections, attendance at selected construction coordination meetings, review of monthly DRAW Package and project close-out reviews.


This property is the former GTE Sylvania Verizon Facility located on 54 Acres of wooded land in Waltham, Massachusetts (just west of Boston).  It is located within the mid-portion of Boston’s Route 128 Technology Corridor and the campus faces the Cambridge Reservoir.


This new headquarters building was the 1st LEED Platinum Certified Core and Steel building in the Commonwealth of Massachusetts and is now occupied by National Grid USA Service Company, Inc.  As part of National Grid’s energy conserving policies related to its electric and natural gas services and products, NATIONAL GRID added solar electric producing (photovoltaic) panels on the building’s roof and solar shading louvers on the south facing facades.  All roof rain water is stored in a large storage tank under the building for use in landscape irrigation and ‘grey water’ uses within the building.


All existing VERIZON buildings in the Phase One portion of the property received internal environmental abatement and demolition of all existing buildings except a small portion.  The remaining portion of the existing buildings were retained and renovated for use by VERIZON, this building is located adjacent to the new three story NATIONAL GRID Headquarters structure.


New off-site traffic improvements included major expansion of traffic capacity and new turning lanes along Winter Street along the Cambridge Reservoir and the main entrance into the new office campus.


For the Phase Two redevelopment of the overall campus an additional three story office building is planned supported by an increased parking garage structure; a new hotel site is also anticipated.


Project Status:   The property was purchased in partnership between Davis Marcus Partners (Developer) and Prudential Real Estate Investors (Equity Partner) to create a world-class headquarters campus.  The first phase of redevelopment, a 312,000 square foot office complex and new six-story parking garage was delivered using ‘Fast-track GMP’ procedures with the project scheduled for delivery within a demanding thirteen month period (‘Core & Shell’ delivered in February 2009).
