If a mechanical duct and a structural beam are designed to occupy the same space, there will be a significant amount of problem-solving before construction can begin. That’s not unusual. On complex projects, dozens — or even hundreds — of design conflicts can surface during the design phase, many of which may never be identified until construction is already underway.
“These decisions are expensive — not only in direct costs, but also in schedule delays. Clients end up paying for both the original work and the additional costs of rework, delays, and reduced productivity.”
What MEP Coordination Actually Involves
The acronym MEP stands for Mechanical, Electrical, and Plumbing. While each discipline involves multiple facets of design and construction, in large-scale facilities such as hospitals, high-rise towers, and airports, MEP systems occupy the greatest amount of vertical space within a building.
Ducts, pipes, raceways, sprinkler systems, and drain lines all run through the same ceiling spaces and risers. They cannot simply be stacked on top of one another, nor can they interfere with the building’s structural supports.
MEP coordination is the process of resolving conflicts between these systems before they arrive on-site. All discipline models — structural, architectural, and MEP — are combined into a single coordinated model. Automated clash detection is then performed on the integrated model to identify and log each conflict, along with its severity.
Once all conflicts have been identified, discipline leads meet in coordination workshops to discuss each issue and collectively resolve them before an updated construction model is issued.
At the conclusion of the MEP coordination process, a complete set of construction documents reflecting how the building will actually be constructed has been prepared — rather than separate design documents created by each discipline working in isolation.
Our MEP coordination and BIM services cover every stage of this process, from initial model federation through to final coordinated issue for construction.
The MEP Coordination Process — Step by Step
Structural, architectural, and MEP discipline models are combined into one federated BIM model.
Software identifies hard clashes, soft clashes, and clearance violations across all disciplines simultaneously.
Each conflict is recorded with a severity level and assigned to the responsible discipline lead for resolution.
Discipline leads collaborate in structured workshops to resolve conflicts and agree on routing solutions.
An updated, fully coordinated construction model replaces the isolated discipline-specific documents.
When Projects Fail — They Tend to Follow a Common Pattern
The design team often works separately, develops designs under a tight deadline, creates discipline-specific models, and fails to coordinate with other teams. Then the project goes to tender, and the structural contractor sets up equipment on the jobsite.
Six weeks later, when the project is in the fit-out stage, it becomes apparent that a pipe run was not coordinated with the beam grid and needs to be modified. By this point, modifying the structure would cost the contractor significant additional dollars; there would be little to no float remaining in the schedule; and resolving a variation order dispute could take months.
RFIs are generated when contractors discover design conflicts during construction that could not have been resolved earlier in the design phase — and each one represents cost, delay, and risk.
No coordination process can catch every conflict between trades prior to the beginning of construction. However, teams that use a structured, documented coordination process consistently face fewer surprises at the job site than those that do not.
The Distinction Between MEP Design and MEP Coordination
MEP design is an engineering process involving sizing equipment, calculating loads, and specifying components in mechanical, electrical, and plumbing systems.
MEP coordination, however, is an entirely separate process that verifies whether the design can physically fit within the building while accommodating all other disciplines.
Even a perfectly executed MEP design can result in an enormous number of challenges if the coordination of structural and architectural models with the MEP model is never accomplished properly. The two processes are fully interdependent and do not replace one another.
Understanding this distinction is critical for clients, project managers, and main contractors. Commissioning MEP design without committing to proper coordination is a risk that consistently manifests as cost overruns and delays during construction.
