ACON Engineering helps developers, general contractors, and builders price multi-family projects with confidence. Multi-family construction carries costs that single-family work does not, including general conditions, overhead, and profit, and a contingency for a project of that scale. Our certified estimators read your plans, quantify every CSI trade across each unit, and price the materials and labor with RSMeans and live zip code rates.
We account for the factors that move a multi-family budget, from building size and site conditions to local codes and material grades. You receive a detailed takeoff in editable Excel that separates hard costs from soft costs, so you see exactly where the money goes before you bid.
We cover every scope your multi-family bid needs, from material takeoffs to bid management. Our estimators quantify each trade and unit, then price the work to your market. Each service below is managed by estimators who specialize in it.
We estimate apartment complexes, condominiums, townhouses, and mixed-use developments of any size. Our team quantifies every unit and shared space, so you get one complete cost basis whether you build low-rise, mid-rise, or high-rise.
We quantify your mechanical, electrical, and plumbing systems with detailed cost breakdowns. Our estimators measure HVAC and piping networks across every unit, so your MEP scope is priced accurately, and nothing gets missed in the bid.
We deliver detailed takeoffs across every CSI trade, including concrete, drywall, masonry, sitework, plumbing, HVAC, electrical, framing, metal, and rebar. Each quantity is measured from your plans and sorted by trade for a clean, bid-ready estimate.
We review your plans for cost-effective material and method alternatives. Our team finds the options that lower your cost without weakening quality or safety, so you submit a leaner multi-family bid and keep the project profitable.
We estimate the cost impact of every design change in real time. When an addition or modification shifts the scope, we measure how it moves your budget, so you stay in control of cost through each revision.
We support your full bid cycle, from the quotation package to bid evaluation and contractor outreach. We organize your takeoffs and prepare competitive proposals, so you bid on more multi-family projects and win a larger share of them.
We deliver a detailed cost estimate organized by CSI division, with material and labor quantities, man-hours, and color-coded marked-up plans. Every file includes general conditions, overhead and profit, and a contingency line, plus a clear list of inclusions and exclusions.

We quantify each trade across every unit and sort it by CSI division. This catches the repetition and scale that drive multi-family cost, so your numbers hold across the whole development.
We return most multi-family estimates within 24 hours. You meet tight bid deadlines without rushing your numbers, so you submit more bids each month and never lose work to a missed cutoff.
We price every line with RSMeans and live zip code rates. Your estimate reflects true local material and labor costs, so your multi-family bid stays competitive and your margin stays protected.

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.
Hard costs cover the physical build, including materials, labor, foundation and landscaping. Soft costs cover everything else, like permits, architectural fees, legal fees and loan interest. We separate the two in every estimate, so you see your full project cost clearly.
We estimate across all three phases of a multi-family project. We cover pre-construction planning and feasibility, the construction phase, and post-construction items like inspections and final finishes. This gives you a budget that follows the project from concept to handover.
We run code-compliance checks, identify hidden costs early, and build smart contingency planning into every estimate. A senior estimator reviews each trade against your plans before delivery. This catches the gaps that cause budget overruns later.
We estimate duplexes, triplexes, quadplexes, condominiums, apartments, garden apartments, and townhouses. We also cover small multi-story buildings, mid-rise and high-rise developments, and mixed-use projects. Each one is priced according to its own scope and scale.
