Mechanical, Electrical, Plumbing, and Fire Protection Design

Tetra Tech’s High Performance Buildings Group specializes in sustainable design and delivery that meets client needs and budgets for every building type.

Aesthetic design might be what catches the attention of occupants, but mechanical, electrical, plumbing (MEP), and fire protection systems make a building perform. Our global team of more than 1,500 MEP and fire protection engineers is recognized across the globe for designing and delivering state-of-the-art systems that support the operation of best-in-class buildings and facilities.

Tetra Tech’s mechanical engineering team provides performance-oriented designs for all building types. We value simplicity of design and are well versed in all aspects of heating, ventilation, air conditioning (HVAC), and energy-efficient systems design. Clients come to Tetra Tech’s mechanical team because they want practical solutions that are easy to operate and maintain and are designed with a balance of innovation and functionality to create spaces that deliver on the triple bottom line of people, planet, and profit. The Tetra Tech team delivers engineering designs that are appropriate for the client’s goals, favoring value and utility.

We use computational fluid dynamics to accurately predict how facilities will behave in relation to air flow, temperature, and pollutant distribution before they are built. Our design experts conduct thermal modeling to predict the performance of all types of buildings, allowing designers to ensure optimum efficiency in energy use. We use system comparisons to identify the best HVAC systems for every project based on location, flexibility, energy efficiency, noise, cost, and maintenance.

Tetra Tech is well equipped to provide outstanding, safe, and reliable electrical solutions for any type of building or infrastructure project. We provide electrical engineering services focused on both individual buildings and community-wide systems. Our systems are well-suited to all client requirements and provide quality services for the full life of the building. From on-site energy generation and high voltage networks to switchboards and uninterruptible power supplies, Tetra Tech has the skills and experience to deliver best-in-class electrical designs on all project types—large and small.

Our diverse electrical expertise includes tasks ranging from straightforward lighting and power layouts to sophisticated fault discrimination analysis and microprocessor control of emergency power generation systems through to glare control from luminaries. We also have extensive experience with interior and exterior lighting, lightning protection, technical earthing, soft wiring systems and retail electricity procurement.

Our team uses sophisticated software analysis tools for the design and simulation of generation, transmission, and distribution systems and regularly prepares a range of electrical reports and audits on due diligence, fault rectification, power quality and energy management.
