Mechanical Engineering Services

Our strength comes from the vast diversity of projects we have worked on throughout the decades that we’ve been in business.

Whether new construction or a renovation, we have successfully designed HVAC, plumbing, fire protection systems, and more for many commercial, education, healthcare, laboratory, ecclesiastical, and government projects.

Key projects include the PPL Center in Allentown (8 stories, 275,000SF, LEED Gold certified) , the Broughal Middle School in Bethlehem (4 stories, 175,000SF, LEED Gold certified), and multiple Lehigh Valley Hospital campuses.

HVAC Systems Design

We design most types of heating, ventilating, and air conditioning (HVAC) systems including: constant-volume air-handling, variable-air-volume air-handling, two-pipe hydronic heating & cooling, four-pipe hydronic heating & cooling, steam heating, enthalpy & sensible heat recovery, packaged rooftop & split-system air conditioning, geothermal, and water-source heat pumps.

Industrial Ventilation

Including: hazardous fume exhaust, dust collection, and paint spray booth ventilation.

Energy Analysis and Life Cycle Cost Studies

We evaluate mechanical system energy consumption as well as conduct life-cycle cost studies to determine long-term system economies. The scope of the studies can be very narrow, i.e. variable speed versus constant speed pumping, or very broad, i.e. centralized versus de-centralized HVAC systems.

Plumbing Systems

Including: domestic water distribution, rain water collection, sanitary waste collection, medical gas distribution, water conditioning, de-ionized water distribution, compressed air and vacuum systems, water pressure booster pump systems, fuel system storage and distribution, and domestic water heating.

Fire Protection Systems

We provide fire protection design services for: sprinkler systems, standpipe systems, fire pumps, dry pipe systems, clean agent systems, and chemical based systems.

Master Planning For Renovation And Expansion

We expand upon life-cycle cost studies and help our clientele develop a strategic plan for mechanical system renovations and/or expansions. We work with the client to develop long term budgeting and construction phasing schedules and tailor the design of mechanical systems to accommodate the long-term plan.

Indoor Air Quality Improvements

We work with facility managers and/or owners to correct indoor air quality problems associated with insufficient ventilation air, inadequate air distribution or filtration, and improper control of relative humidity.

Acoustical Analysis of Mechanical Systems

We perform acoustical analyses of mechanical systems during the building design phase to reduce potentially significant noise problems. We work with facility owners and operators to determine noise sources and corrective solutions in existing facilities.

Central Plant Design

We design both central heating plants and central cooling plants. We work closely with the owner/operator to evaluate and specify the proper equipment and develop a plant layout that enhances maintenance and operation.

Automatic Temperature Controls And Facility Management Systems

We are experienced with major manufacturers of automatic temperature controls and facility management systems; we are also familiar with several smaller but well-qualified controls contractors. We work with the owner/operator to specify control or management systems appropriate for their unique application.

Electrical Engineering Services

Working closely with facility operators, architects, and contractors to develop conceptual ideas into viable construction projects, LVE designs electrical and communications systems as part of our vast engineering skillset.

An example would be our work on the renovation of Northampton Community College’s Data Center, where we made modifications to increase reliability of the electrical system and generator service among numerous other mechanical and electrical engineering upgrades.

We work hard to ensure our clients are happy, and many become repeat customers. Case in point: we have happily collaborated on five other projects for Northampton Community College beyond the one mentioned above.

Electrical Power Distribution

We design and specify complete standard and specialized power distribution systems as dictated by facility requirements. These include: low voltage (120V-480V), medium voltage (5kV-35kV), backup generation, and uninterruptible power supply (UPS) systems.

Power System Studies

We provide power system studies which can be associated with master planning for expanding or renovating an existing facility, and can also include: diagnosing power quality problems and identifying power conservation and cost saving opportunities.

Lighting And Lighting Controls

We design and specify complete standard and specialized lighting systems according to the project architect’s design or our own design. We design indoor and outdoor architectural lighting, theatrical lighting, stadium and sports lighting, and street lighting.

Fire Alarm And Security Systems

We design and specify complete fire alarm and security systems to satisfy code requirements and facility needs. These include: manual and automatic fire alarm systems, perimeter and interior security, and video surveillance systems.

Traditional Communication Systems

We design and specify traditional communication systems which include telephone systems and intercom systems. We also design television origination and distribution systems.

Data Networking Systems

We design and specify data networking systems to the level required by the project, including VoIP. We design horizontal and backbone spaces and wiring using copper or optical fiber cable, as well as hubs, switches and routers.

Other Services

In addition to design services, we are happy to accommodate clients with other tasks related to engineering. These include:

CAD Services

We provide computer aided drafting (CAD) services to facility managers and contractors; we convert hand-drawn sketches or existing building drawings to versatile AutoCAD and REVIT electronic documents.

Construction Documentation And Administration

We prepare construction documents, drawings and specifications, for both the public and private sectors. Lehigh Valley Engineering can provide complete administrative services including: bid and contract review, shop drawing review, construction observation, and final construction close-out.

Existing Conditions And As-Built Documentation

We work with the facility owner/operator to develop highly accurate electronic drawings of existing mechanical and electrical systems. At the owner’s request, we can provide highlighted drawings depicting special service features such as isolation valves, control panels and valves, motor starters, and safety devices.

Code Compliance Review

We provide code review services for proposed mechanical and electrical designs as well as existing installations.

Expert Witness Services

We provide expert witness reports and testimony related to HVAC and electrical litigation.
