Engineering 

Harriman has a proven track record of serving communities with a commitment to quality and client satisfaction. Our success is, in part, driven by our talented engineers who consistently design accurate, cost effective, and creative solutions while maintaining a practical mindset. We have organized our business to deliver integrated services through a variety of disciplines because cross-departmental collaboration provides more unified, inspired solutions, and reduces costs.

Our engineers are skilled at analyzing existing systems and determining how best to upgrade them to increase their performance and achieve optimal lifecycle costs. The metrics used in evaluating the implementation of new systems include energy efficiency, serviceability and indoor environmental conditions. Our daily design practices always considered energy efficiency and comfort of those who use the building as well the service techniques required to work on the systems.  We work closely with those who use and operate the building to identify their requirements and the source of specific issues so that solutions can be designed.

Using the latest in applied technologies we are able to design systems that can communicate and relate the differing building systems together and to track trends that allow adjustments to be made from a central building or campus automation center.  We have a proven track record in designing energy management systems with direct digital controls that provide cost-efficient operation and the means for tracking energy data. We have completed renovations that expanded existing systems, designed new systems that interface with existing systems, and designed all new systems for both new buildings and existing facilities.  Energy conservation, ease of operation, and the comfort of building occupants are primary considerations.

Team members have extensive experience with the various types of systems and know how they interface with different types of building equipment. We understand the strengths and weaknesses of the systems and can provide objective, non-biased feedback on their benefits in specific applications.  We are also adept at performing the field investigations needed to evaluate existing systems.

A unique skill our engineers practice is the engineering of the complete infrastructure utilities required to support the construction and renovation of buildings. This starts with a sustainable approach to analyzing and supporting the differing energy densities on campus and how to distribute the required utilities to support the campus in a holistic approach. This approach generally allows for more synergies between different systems. Exploring these options generally allows for lower energy production costs either in purchased fuel or at a central plant as well as reducing peak demands on all utilities.  The utilities commonly reviewed include high pressure campus steam, campus district hot water, domestic water, fire protection, and medium voltage distribution.

Harriman’s Structural Engineering team offers extensive experience in the evaluation and design of a variety of types of structures and structural systems, whether existing or new.  We tailor our creative solutions to every client and we invest in state of the art structural design software and building information modeling (BIM) software to ensure accuracy and constructability.

Harriman’s civil and environmental engineering staff has broad experience in site engineering, environmental engineering, regulatory agency permitting, site selection, site planning and site master planning. Public and private sector civil site design experience includes municipal facilities, educational institutions, healthcare facilities, commercial and industrial development, and parks and recreational facilities.
