What MEP coordination covers
MEP engineering coordination on Denver-metro projects means bringing design professionals into mechanical, electrical, and plumbing scopes: HVAC loads and duct layouts, electrical one-lines and panel schedules, plumbing risers, and energy-code documentation. The general contractor coordinates schedule, permitting, and construction around sealed drawings. A municipally licensed Denver general contractor does not replace the engineer of record; it coordinates design professionals and the build team. Cost is project-specific and depends on building type and system complexity.

When CPD wants engineered packages
City and County of Denver Community Planning and Development asks for engineered drawings, calculations, specifications, and energy-code information when commercial or multifamily work includes electrical, mechanical, or plumbing changes. Additions typically need building plus electrical, mechanical, plumbing, and Sewer Use and Drainage (SUDP) review through DOTI. Equipment replacements can trigger mechanical review for capacity, makeup air, and exhaust.
text
Permits and who coordinates the work
MEP packages are submitted through Denver CPD e-permits with the building permit. Colorado DORA regulates electrical and plumbing licensing. Cities and counties license general contractors. Colorado has no statewide general contractor license. Autotelic acts as a municipally licensed Denver general contractor and coordinates licensed specialty trades plus the design professionals required for the project.
text
What buyers should prepare
Project type (tenant finish, addition, equipment swap), any existing drawings, and known panel, HVAC, or plumbing capacity limits.
FAQ
Common questions
Do MEP changes need engineered drawings in Denver?
Often yes for commercial and multifamily work. CPD commercial plan review lists electrical, mechanical, and plumbing as drawing-review items when those systems change.
Who handles MEP permits and licensing?
A municipally licensed Denver general contractor coordinates the project, design professionals, and specialty trades. Colorado has no statewide general contractor license.
Is the GC the MEP engineer of record?
No. Sealed mechanical, electrical, and plumbing design is provided by design professionals who seal the documents. The GC coordinates construction around those documents.
When is an SUDP involved?
Denver DOTI reviews Sewer Use and Drainage with most building-permit packages, including many remodels, because fixture or drainage changes can affect sewer use.
What information helps define scope?
Desired system changes, existing drawings if any, photos of equipment and panels, and city or county.

DESIGN SERVICES
Discovery & Site Analysis
Needs + preference programming, site survey, as-built documentation, feasibility.
We walk, measure, and photograph your property — existing conditions, utilities, structure, and constraints. You get the as-built documentation and feasibility read that every later decision rests on.
Learn more →Concept Design & Space Planning
Schematic design, floor plan studies, layout options.
Your scope becomes schematic floor plans you can compare side by side — circulation, daylight, adjacencies, and what each option does to the budget. Layout decisions happen on paper, where changes are cheap.
Learn more →Architectural Design & 3D Renderings
Design development, materials + finishes, photorealistic visualization.
The chosen concept resolves into materials, finishes, fixtures, and lighting — with the automation layer drawn in. Photorealistic renderings let you walk the space and adjust before anything is priced.
Learn more →Construction Documents & Permitting
Full CD sets, structural + MEP engineering coordination, permit-ready drawings.
Approved designs become coordinated architectural, structural, and MEP sheets — the set your jurisdiction permits from and trades build from. We submit, track, and answer review comments.
Learn more →CONSTRUCTION
New Construction & Custom Homes
Ground-up homes and light commercial, dirt to keys.
Ground-up residential and light commercial builds — foundations through finishes, including modular and steel construction. One accountable builder from dirt to keys.
