What We Offer
From a first budget number to a fully itemized bid package, these are the mechanical estimating services we build estimates around.
A · FULL BID-DAY ESTIMATES
Complete mechanical bid estimating from your drawing set - equipment, ductwork, piping, insulation, and labor priced line by line and formatted to drop into your bid form.
B · QUANTITY TAKEOFFS
Sheet-metal, duct fittings, dampers, grilles, and terminal units counted and tracked by area, floor, or system so you know what's driving your ductwork cost.
C · PIPING SYSTEMS
Chilled water, hot water, steam, and refrigerant piping estimated with fittings, valves, and insulation broken out separately from equipment cost.
D · COORDINATED MEP SCOPE
When a project needs mechanical estimating alongside electrical and plumbing, our MEP estimating services keep quantities and assumptions consistent across trades on the same drawing set.
E · GC AND SUBCONTRACTOR SUPPORT
We support general contractors pulling a mechanical number for a GMP, and mechanical subcontractors preparing their own competitive or negotiated bid - our subcontractor estimating services match the detail each side needs.
F · MID-PROJECT PRICING
Fast add/deduct pricing on scope changes and RFIs, so a change order gets priced and submitted before it holds up the schedule.
Who We Serve
A general contractor, a mechanical subcontractor, and a developer all need a different level of detail from the same set of drawings - we build to match.
ID-01 · GC
Mechanical numbers formatted to sit alongside every other trade in a GMP or lump-sum bid.
ID-02 · SUB
A full mechanical bid estimating package so your team spends its time on relationships, not takeoff hours.
ID-03 · OWNER
An independent construction cost estimate to sanity-check contractor pricing before you sign a contract.
ID-04 · DESIGN-BUILD
Estimating support that tracks with drawings as they develop, from schematic budget through final bid documents.
ID-05 · PLANT
Process piping and plant-mechanical pricing for Michigan's manufacturing and automotive-supplier facilities.
ID-06 · GROWTH
Overflow estimating capacity during a busy bid season, without carrying a full-time in-house estimator.
Project Types
We estimate mechanical work across the project types most common to the Michigan construction market, including the state's manufacturing and automotive-facility base.

Single-family new construction and remodels, townhome and apartment HVAC, residential ductwork and piping, geothermal and heat pump systems.
Commercial
Office and retail tenant improvements, restaurants and hospitality, healthcare clinics, schools, warehouse and self-storage buildouts.
Industrial & manufacturing
Automotive and manufacturing facility mechanical systems, process piping, plant ventilation and refrigeration, motor and equipment room upgrades.
Institutional & specialized
Hospitals and healthcare systems, university and campus infrastructure, laboratories, data centers, and municipal buildings.
What's Included
Every estimate is built line by line from your drawings, not backed into from a square-footage average.
Equipment, ductwork, piping, insulation, and controls, counted directly from the mechanical drawings and specifications.
Hours by task and crew classification, based on productivity assumptions for the Michigan mechanical labor market.
Current supplier and distributor pricing on rooftop units, boilers, chillers, pumps, and specialty equipment.
A written list of what's included and excluded, and any assumptions made where drawings were unclear or incomplete.
Flags on scope affected by the current Michigan Mechanical Code edition or a state-specific amendment.
Delivered in Excel, PDF, or your preferred bid form, organized by CSI division and building area.
Pricing for owner-requested alternates and unit rates for anticipated change orders and RFIs.
A point of contact who worked the takeoff and is available to walk through the numbers before you submit.

How the Process Works
The same six steps whether it's a Detroit commercial package or a Grand Rapids plant mechanical scope.
01
Plans, specs, and addenda - PDF, CAD, or a plan-room link.
02
Full digital quantity takeoff, checked against the drawing set.
03
Material and labor priced against current Michigan data.
04
A second estimator checks quantities and pricing before delivery.
05
Estimate delivered in your format, with a short assumptions walkthrough.
06
Addenda and late changes priced as add/deduct items through bid day.
Software & Pricing Sources
Takeoff software, cost databases, and Michigan supplier and wage data - not a flat national average applied blind.
PlanSwift / On-Screen Takeoff
Digital quantity takeoff from PDF and CAD drawing sets
Bluebeam Revu
Markup, measurement, and addenda tracking across the drawing set
Trimble
Detailed sheet-metal and piping takeoff on larger projects
RSMeans
Cross-check on unit pricing and labor productivity assumptions
Excel / custom templates
Final bid-day formatting matched to your bid form
Current equipment and material pricing from regional Michigan mechanical suppliers.
Applied on public and prevailing-wage-covered projects.
Matched to the project's labor agreement or local market.
Accuracy & Quality Control
An estimate only helps you if it still holds once the job starts. Every deliverable is quantity-checked by a second estimator who wasn't involved in the original takeoff, with every line item traced back to a specific drawing page or spec section - not a generic per-square-foot assumption. Material and labor pricing is refreshed against current supplier and wage data before anything is sent out, and every assumption or exclusion is written down rather than buried inside a spreadsheet formula.
01 - Second-estimator check
Independent review of quantities and pricing before delivery.
02 - Drawing-traced line items
Every quantity ties back to a specific sheet or spec section.
03 - Documented assumptions
Exclusions and assumptions written out, not hidden in a formula.
Why Choose Estimating Buddies
Michigan-specific pricing, coordinated MEP numbers, and a named estimator - built around how contractors actually bid in this market.
01
Labor and material costs reflect actual Detroit, Grand Rapids, and statewide Michigan rates, including the automotive and manufacturing sector.
02
We regularly pair mechanical estimating with electrical and plumbing scope, so numbers stay consistent when a project needs full MEP estimating services.
03
Standard estimates in 24–48 hours, with rush options for tight bid schedules - you know the timeline before you commit.
04
You know the cost of the estimate itself before we start, with no fee tied to your bid outcome.
05
You'll always know who built your number and can reach them directly with questions before you submit.
Service Area
We work statewide, with the deepest project volume across Southeast Michigan. If your project sits in Michigan, we can estimate it - including public and prevailing-wage work.
Codes & Compliance
Code editions change equipment selection, ventilation rates, and labeling requirements - and change what a job actually costs. We track the code your permit will be reviewed against.
Mechanical work in Michigan is governed by the Michigan Mechanical Code (Part 9A of the Construction Code), which currently adopts the 2021 International Mechanical Code with Michigan-specific amendments. LARA's Bureau of Construction Codes has proposed rulemaking to move the state to the 2024 IMC, so a project's applicable edition can depend on when it's permitted.
MI-01
State law (Public Act 230 of 1972) authorizes LARA's Bureau of Construction Codes to adopt and administer a single statewide construction code, including the mechanical code.
MI-02
Sets the adopted code edition, reviews proposed amendments through public rulemaking, and certifies local building officials and inspectors.
MI-03
Roughly 1,600 local units of government across Michigan hold authority to enforce the adopted code, with the Bureau serving as the authority in jurisdictions without local coverage.
What this means for your estimate
We note the applicable code edition and any Michigan amendments that affect equipment, ventilation, or labeling scope in your estimate's assumptions.
Cost & Pricing Factors
Every project is quoted individually. These are the factors that most often change the number.
01
Square footage, number of systems, and whether ductwork, piping, and controls are all included in the takeoff.
02
Fully detailed construction documents need less interpretation than early or schematic-level drawings, affecting both cost and turnaround.
03
Rates vary by region and by whether a project is prevailing-wage, union, or open-shop, changing the labor cost applied to identical scope.
04
Projects reviewed under the current Michigan Mechanical Code edition may need additional ventilation, labeling, or equipment scope reflected in pricing.
05
Rooftop unit availability and copper, steel, and aluminum pricing can shift a material budget between design phases.
06
Standard bid timelines are priced differently than rush requests with a compressed deadline.
07
A rough conceptual number costs less to produce than a fully itemized, bid-ready mechanical estimate broken out by CSI division.
