Why MEP Engineers are Central to Every Building Project

Project Solutions Thought Leadership


You might be familiar with the general definition of engineer—technical professionals, also known as endearing nerds, who develop solutions to solve problems in nearly every facet of our lives.

Like specialists in any other industry, the MEP Engineer has a special skill-set focus on Mechanical, Electrical, and Plumbing (MEP) engineering. In residential and commercial buildings, these three elements are often designed by engineering firms that specialize in MEP.

MEP engineers belong to a professional classification with the responsibility for planning, designing and administering mechanical, electrical and plumbing systems which often encompasses development of standards, specifications, cost estimates and inspection procedures.

In today’s market, MEP engineering projects contribute to major trends that drive a process of change in the building industry. The construction of buildings or upgrade of new buildings and facilities involves the design and implementation of numerous sophisticated systems. MEP design projects and installation are complex and form part of the scope for design and construction of building and infrastructure projects. MEP projects are integrated systems which establish the nexus between the architect’s design and engineering tasks. Design for new buildings or building improvement projects is also typically integrated with other multidiscipline professional services such as architecture, electrical engineering, fire suppressant systems, HVAC systems (heating, ventilating and air conditioning), controls and other specialty fields. When each of MEP elements are designed in
isolation, it leads to misalignment of systems, project delays and escalated costs. The scope of MEP design has to define during the initial project analysis. The person who has the overall responsibility for successful initiation, planning, design, managing
scope, budget and schedule including execution, monitoring, controlling and final commissioning of the project is the project

What about the Core of the MEP Engineering?

Imagine walking into the building structures without mechanical systems, electrical connections and plumbing fixtures in residential or commercial projects. Without MEP design engineers, that scenario would look like living in a cave. To make sure that everything undergoes proper design, execution and delivery on time – especially projects with a high level of complexity – it’s a good idea to strengthen the project team with MEP engineers. Qualified MEP firms significantly enhance security, safety, human comfort, and functionality of the building. Experienced MEP engineers work very closely with the project manager to control project risk and ensure that high building performance with comfort are attained. The role MEP design consultants is critical in creating essential steps and this can help to mitigate inefficiencies and costly mistakes down the road. Their
overall goal in design and build projects is to ensure the safe, comfortable and environmentally friendly operations. MEP engineers bring about the functional “heart” of the building systems. Again, it’s always beneficial for MEP designers to be involved early in the pre-designing phase working closely with the architect in the design development process so as to plan and size equipment systems at the optimum performance level.

MEP Engineering services are typically delivered in three main phases in most building and facility design and construction projects. For quality control and professional integrity, MEP engineering design requires professional licensing regulated by states in the United States.

Phases of MEP Engineering Design and Build Project

The process by which
building projects is delivered to the project owner may be segmented into following five phases, referred to as the project
delivery phases. Although there is usually some overlap between adjacent phases, they generally follow these broad phase orders:

  1. Pre-design Phase
  2. Design Development Phase
  3. Pre-Construction Phase
  4. Construction Phase
  5. Post-Construction Phase

The coordination of these three main phases is usually done by construction manager.

9 Key Roles of MEP Engineers During Initial Pre-Design Phase

  1. Effective interaction with project manager, clients, architects, design team professionals depending on the complexity and scope of project, and other stakeholders.
  2. Work with project team to perform site assessment and selection and verification of the appropriateness of site.
  3. Examine jurisdiction regulatory constraints pertaining to mechanical, electrical and plumbing codes and design, and prepare project specification including early integration of materials, equipment and space with the design team.
  4. Perform cost estimate and perform conceptual design level constructability review with input from construction project manager
  5. In concert with project manager and architect (sometime), develop project proposal and work plan that ensure on-time and on-budget delivery of MEP scope of service.
  6. Draft and distribute project meeting agenda or the role may be assigned to a team member.
  7. Prepare design and construction delivery project schedule with coordination and input from construction project manager.
  8. Find out whether project owner would like the project to achieve sustainability rating, like the U.S. Green Building Council’s (USGBC’s) and Leadership in Energy and Environmental Design (LEED) scorecard and document impact of selected equipment systems to project stakeholders.
  9. Perform Life cycle cost analysis on large scale budget to obtain best value for the owner. This is given a due consideration to system alternatives that result in long-term least cost option.
