We think HEI is unique because of the level of experience we bring to each and every project we are associated with.  This experience applies to all market sectors we service.  We have had the good fortune of working with many great developers, consultants and contractors over the years.

HEI has considerable experience in the commercial development sector.  From master planning 1MSF retail shopping centers to developing industrial distribution facilities with rail spurs we have the knowledge and skills to deliver a success project.

Below are the general commercial uses we have planned, designed and permitted for.



Mixed Use

Mixed use developments combine two or more different types of land uses, such as residential, commercial, and entertainment, in close proximity. HEI has worked on several projects that have incorporated this concept into the site programming with success. Working closely with an overall development team we work towards maximizing the development potential of the property at the same time minimizing the impact to the surrounding area and environment. Mixed use developments provide it’s tenants and residents options and tend to create a more robust and fluid environment.

Life Science / Labs
HEI’s collective experience with life sciences/laboratory projects includes design and permitting support for private manufacturing/ biotechnology firms and higher education clients. This market sector often has unique planning criteria that require sensitive site/infrastructure designs to achieve operational protocols, environmental protection, and development of sustainable sites to promote employee well being in a corporate campus setting.

HEI has provided permitting, site design and civil engineering services for several hospitality uses.  We have worked with national restaurant chains, hotel chains, and local private developers.  Locations have been in urban and sub-urban environments.  

Institutional / Academic
HEI’s staff have experience with planning, design, and permitting for private higher education colleges and universities. Design experience includes campus/infrastructure planning, student/resident housing, academic buildings, campus center/recreation facilities, and athletics.

Public / Non Profit
Our most recent public sector experience was with the Department of Veteran Affairs and it involved a major expansion project for the Massachusetts National Cemetery including new burial areas, a new public information center, garage complex, environmentally sensitive wasbay facility and new columbaria.  Civil Engineering, MEP, Fire Protection, Landscape Architecture, Irrigation design, Architecture, Cost Estimate, Interior Design were directly under Mike’s control and management.
