What structural coordination covers
Structural engineering coordination on Denver-metro projects means bringing design professionals into remodels and additions when load paths change—wall openings, additions, foundation work, and non-prescriptive framing. The general contractor coordinates schedule, permitting, and construction around those 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 complexity and site conditions.
text
When drawings are typically needed
CPD commonly expects engineered details for load-bearing alterations, underpinning, many second-story additions, and work beyond prescriptive code limits. Existing conditions may need field verification.
text
Permits and who coordinates the work
Engineered packages are submitted through City and County of Denver Community Planning and Development with the building permit. 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.

What buyers should prepare
Goals for openings or additions, any prior plans, and known foundation concerns.
FAQ
Common questions
Do I always need an engineer to open a wall?
Not always for simple partitions, but load-bearing changes typically need engineering and CPD permits. Assess the load path first.
Who handles 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 engineer of record?
No. Sealed structural design is provided by design professionals who seal the documents. The GC coordinates construction around those documents.
When are site visits needed?
Often for existing conditions, special inspections, or complex foundations. The engineer defines observation needs.
What information helps define scope?
Desired structural changes, photos, existing drawings if any, 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.

New Construction & Custom Homes
Ground-up homes and light commercial, dirt to keys.
