Denver projects often cost more than the drawings suggest. Much of the Front Range sits on expansive clay that requires over-excavation, structural fill and specialized foundation work. Current energy codes also add scope through higher-performing building envelopes and electrified building systems, while snow load requirements can increase structural costs. These factors are easy to underestimate when using generic pricing or outdated cost data. ACON Engineering builds each estimate around the project's geotechnical report, current Denver market rates and the applicable code requirements. A senior estimator reviews the completed estimate before delivery, giving contractors a reliable number they can bid with.
Quantities are taken directly from your drawings and priced using current local market rates. You receive a detailed estimate that is ready for budgeting, bidding and cost planning.
We prepare estimates for custom homes, multifamily developments and residential communities. Foundation quantities reflect the project's geotechnical report, including over excavation, structural fill and drilled piers where required, so the estimate matches actual site conditions.
Commercial estimates cover offices, retail buildings, healthcare facilities and mixed-use developments across every CSI division. Current energy code requirements, building envelope assemblies and mechanical systems are included from the beginning instead of being added later.
We estimate warehouses, manufacturing plants and distribution facilities by trade, including concrete, structural steel, roofing and MEP systems. Roof framing, loading requirements and structural components are priced to local design standards for accurate budgeting.
Schools, municipal buildings, transportation facilities and other public projects are prepared in the format required by the bidding agency. Alternate pricing, bid schedules and unit prices are organized to support the public procurement process.
We support developers and private owners with accurate construction budgets during planning and design. Cost-saving opportunities are identified where practical, helping control project costs without affecting performance or quality.
Federal and state projects are prepared with prevailing wage requirements, bonding costs and agency specific documentation already considered. Estimates are organized by CSI division to match procurement requirements and simplify bid submission.

Your estimate is delivered in editable Excel, organized by CSI division with material, labor, and equipment broken out separately. You'll also receive marked up drawings showing exactly what was measured, along with clear inclusions and exclusions.
Get 3 redacted full sample sets covering takeoff, estimate, and schedule. No call required.
We keep the process straightforward. One estimator manages your project from the time you send the drawings until the completed estimate is delivered.
Upload your plans, specifications, addenda, and geotechnical report in PDF, CAD, or DWG format. We review the documents, identify any missing information, and provide a fixed price quote.
Our team measures quantities directly from your drawings and organizes them by CSI division, making the estimate easy for subcontractors and project teams to review and price accurately.
Material, labor, equipment costs are based on Denver pricing. Requirements for over excavation, structural fill, and energy code scope are included where required.
A senior estimator performs a final quality check before the estimate is delivered in Excel and PDF, complete with marked up drawings for reference.
We prepare takeoffs using PlanSwift and On Screen Takeoff, review drawings in Bluebeam, and price estimates with current RSMeans cost data. Earthwork quantities are measured directly from the plans, and your files arrive in formats your team can review, edit, and use immediately.






Accurate estimates come from careful quantity takeoffs, current pricing, and experienced review. Here's what goes into every estimate we prepare.
Expansive soils can significantly affect foundation costs. We quantify over-excavation, structural fill, and related earthwork directly from the geotechnical report and project drawings instead of relying on allowances.
Denver's energy code adds cost in areas many estimates overlook. We include the required building envelope, insulation, and system upgrades so your estimate reflects today's construction requirements.
Labor, material, and equipment costs are based on current Front Range market conditions. That gives you pricing that reflects where the project is being built instead of relying on national averages.
Our estimates cover the full project scope, from sitework and concrete through structural steel, framing, MEP, and finishes. Everything is organized into one clear file for easier pricing and review.
Our estimating team follows AACE and ASPE estimating standards. Every estimate is reviewed by a senior estimator before delivery to help improve consistency and accuracy.
Most estimates are completed within 24 to 48 hours. If drawings change or an addendum is issued before bidding, we'll revise the estimate at no additional cost.
Answer the three questions below to get a rough idea of your estimating cost. When you're ready for an exact quote, simply send us your drawings.
Tell us whether you're pricing a residential, commercial, industrial, or public project. The project type determines the trades and level of detail required.
Enter the building's square footage or estimated contract value. Larger and more detailed projects typically require additional takeoff and estimating time.
Select the work you need priced, whether it's sitework, earthwork, structural work, MEP systems, finishes, or a complete CSI estimate. We'll prepare the estimate based on the scope you choose.

ACON Engineering is great to work with. The team is hardworking, professional, and takes pride in their work. They respond quickly, communicate clearly, and keep every project moving smoothly from start to finish.

Acon Engineering is a trustworthy and professional firm. They consistently deliver on time and are excellent to work with throughout the process. Their estimates are clear, organized, and supported by detailed documentation.

It was a pleasure working with them. The team was professional, responsive, and easy to communicate with throughout the project. Their service was reliable, efficient, and delivered exactly what was promised.
Expansive clay across the Front Range swells and shrinks with moisture, so foundations often call for over excavation and moisture-conditioned structural fill. That puts thousands of cubic yards of earthwork into a project that looks straightforward on the plans, and it is priced off the geotechnical report rather than a rule of thumb.
It helps considerably. The soil report sets the foundation approach and the depth of over excavation, which are two of the largest variables in a Denver bid. Without it we price against a stated assumption and flag it clearly, so you know what the number rests on.
They add envelope scope and push mechanical systems toward electrification. Insulation, air sealing, glazing performance and equipment selection all shift, and published cost tables trail the code by a year or more. We count that work with the building rather than treating it as an allowance.
Yes, in ways that reach the mechanical scope. Heating loads, equipment sizing and roof framing for snow all run above what a national benchmark assumes. Those quantities are calculated for the conditions rather than carried over from a lower-altitude project.
Yes. Public and government projects are estimated to the format the agency asks for, with alternates, unit pricing, bid schedules, prevailing wage and bonding accounted for. The file is organized by CSI division so it lines up with the solicitation.
Labor and subcontractor rates change between the urban core, the surrounding suburbs and the mountain corridor, and haul distance moves material cost. Pricing follows the location of the project, not a metro average.
Quantities are measured in takeoff software off your drawings, not scaled by hand, and priced to current local rates. A senior estimator rechecks the file before release, and most estimates come back within 24 to 48 hours.
Send us your drawings, specifications, and geotechnical report, and we'll prepare a detailed estimate based on current Denver pricing and your project's actual site conditions.
