Here's something most MEP contractors already feel but can't quite name: the difference between winning a bid and actually making money on it keeps getting harder to explain.
Labor costs are up. Finding qualified workers is harder than it's ever been — the AGC's 2025 Workforce Survey found that 92% of contractors report difficulty hiring qualified workers, and 45% say labor shortages are the leading cause of project delays. The industry needs to attract 349,000 net new workers in 2026 alone, rising to 456,000 in 2027, according to the Associated Builders and Contractors.
And yet the deeper problem isn't the one making headlines.
McKinsey has been documenting the industry's productivity story for years. Over the past two decades, construction productivity has grown at just 0.4% annually — roughly one-fifth the rate of the broader economy. In the United States specifically, it has actually declined since the 1960s, even as labor costs climbed faster than inflation. The U.S. MEP services market, meanwhile, is projected to grow from $32.55 billion in 2025 to $47.05 billion by 2031 — compressing timelines and further raising execution stakes.
But here's the part that rarely gets discussed: the productivity gap isn't just between construction and other industries. It's between you and the contractor down the street.
The Spread Your P&L Already Knows About
In MEP work specifically, the performance gap between a top-quartile crew and a median crew performing the same scope is 30 to 40 percent. Same drawings. Same materials. Same scope of work. One crew finishes an HVAC installation in 40 hours. Another finishes it in 55-60.
That's $1,300 in labor cost — on a single task.
Multiply that across 15 to 20 projects a year, and the math gets uncomfortable fast.
"A few years ago, when the economy was thriving, and everyone was flush with money, it was really easy to make money even if you had less-than-ideal execution," said Ara Mahdessian, CEO of ServiceTitan. "But now, we've got to be near perfect in our execution on every job to consistently make the healthy profit that I think all contractors deserve."
It's not that the work is getting harder. It's that every job starts from scratch.
Why Most Contractors Are Flying Blind
The frustrating reality is this: most MEP contractors don't have access to reliable productivity data. They operate on rules of thumb passed down from estimators who learned from other estimators — none of whom were systematically tracking actuals against estimates at the task level.
The 2025 State of the MEP Industry Report found that while financial outcomes are widely tracked, operational performance indicators tied to field productivity remain a significant blind spot — most companies know how projects turned out, but can't identify the drivers behind performance variance. The EVOLVE MEP 2025 recap echoed this: contractors who invested in digital workflows and connected data in 2025 are already pulling ahead of peers heading into 2026.⁷
The result is a business running on institutional memory instead of institutional knowledge. When a PM retires or moves on, the hard-won lessons about that downtown retrofit or the tight-ceiling hospital job walk out the door with them.
The best operators have cracked this. Not through some sophisticated analytics platform or data science team — but through the discipline of measuring what they do, closing the loop on every project, and letting the data compound over time.
As Tyler Edelman of Edelman Inc. puts it simply: "It's definitely easier for us doing it the second, third, and fourth time."
That sounds obvious. But it's only true if you're actually capturing what happened the first time.
2026 MEP Labor Productivity Benchmarks
What follows is a grounded baseline — derived from analysis of 200+ completed MEP projects across project types and geographies — that your estimating and operations teams can put to work today. These aren't theoretical. They reflect field conditions, variability in crew composition, and the kind of real-world complexity that shows up on actual jobsites.
Use them as a starting point. The goal is to replace them with your own data as fast as possible.
HVAC Systems
Ductwork Installation
The range here is wide because conditions vary enormously, and most estimating errors happen when contractors apply a single number across all of them.
Simple new construction, open ceilings, straight routing: 3.5–4.5 hours per 100 LF
Standard routing with moderate obstacles: 4.5–6.0 hours per 100 LF
Complex routing in existing building with tight spaces and ductwork conflicts: 6.5–8.5 hours per 100 LF
To put that in real terms: a 500 LF ductwork installation in simple new construction takes 17 to 22 crew hours. The same scope in a complex existing building takes 32 to 42 hours, nearly double. Bid both jobs the same way, and you've already lost one of them before a tool is lifted.
Rooftop HVAC Unit Installation
Single unit, new building: 14–18 hours per unit
Single unit, existing building: 18–24 hours per unit
Unit with new curb and structural modifications: 24–32 hours per unit
A practical example: two 5-ton units with new curbs on an existing building. Expect 40 to 50 hours under clean conditions, 48 to 60 hours if structural or access complications arise. The difference between those two numbers is a conversation worth having before you bid — not after you're on site.
Chiller Installation (includes unboxing, placement, piping, electrical, controls, and startup)
50–100 tons, new building: 60–80 hours
50–100 tons, existing building with existing piping/electrical: 80–120 hours
100+ tons with major structural work: 120–160 hours
Air Handler Installation
Small (2–5 tons), new building: 24–32 hours
Medium (5–15 tons), new building: 32–48 hours
Retrofit in existing building: add 40–60% for access constraints
Ductwork Sealing and Pressure Testing
Standard access: 6–8 hours per 1,000 CFM installed
Constrained access: 8–12 hours per 1,000 CFM
Plumbing Systems
Copper Piping Installation (measuring, cutting, sweating joints, securing, testing; materials staging not included)
Simple roughing, basement or minimal routing: 3.0–3.5 hours per 100 LF
Standard roughing through walls: 3.5–5.0 hours per 100 LF
Complex slab or overhead work: 5.0–7.0 hours per 100 LF
PVC and plastic piping run approximately 15% faster than copper. That spread adds up across a large job — and it's the kind of detail that lives in your crews' heads, not your estimates.
Water Heater Installation (includes removal of old unit, connections to water/gas/electrical, venting, and startup)
Tankless unit, standard conditions: 12–16 hours
Tank unit (gas): 10–14 hours
Tank unit (electric): 8–12 hours
Backflow Preventer
Installation and initial test: 4–6 hours
Annual recertification: 1–2 hours
Commercial Fixtures
Full bathroom (5–6 fixtures): 6–10 hours
Kitchen zone: 4–8 hours
Electrical Systems
Conduit Installation
New building, open ceilings: 2.5–3.5 hours per 100 LF
Walls or existing building: 3.5–5.0 hours per 100 LF
Underground or slab: 5.0–8.0 hours per 100 LF
Wire Pulling
Simple (4 conductors, straight runs): 4–6 hours per 1,000 LF
Complex (12+ conductors, routing constraints): 8–12 hours per 1,000 LF
Electrical Panel Installation (mounting, main and branch breakers, labeling; rough conduit estimated separately)
100–200A, simple: 20–28 hours
200–400A, standard: 28–40 hours
400A+ or complex feeder: 40–60+ hours
Lighting Installation
Recessed fixtures in drop ceiling: 1.5–2.0 hours per fixture
Surface-mount, existing building: 1.0–1.5 hours per fixture
Specialty (emergency, outdoor, high-bay): 2.0–3.0 hours per fixture
Fire Alarm Systems (device mounting, wire pulling, panel programming, system testing)
Basic (10–20 devices): 40–60 hours
Medium (20–40 devices): 60–100 hours
Large (40+ devices): 100–160+ hours
The Modifiers: Where Estimates Go Wrong
Base rates are only part of the story. The conditions on any given job can move your actual hours by 50% or more — and the most common estimating errors aren't in the base numbers. They're in the failure to apply adjustments consistently.
Building Conditions
Existing vs. new construction: +20–40%
Historic building with constraints: +30–50%
Occupied building with limited access: +15–30%
Environment
Cold weather below 40°F: +10–20% (especially soldering and controls work)
High altitude above 5,000 ft: +10–15%
High dust or contamination: +15–25%
Schedule and Coordination
Compressed or accelerated schedule: +15–30%
Poor trade sequencing: +10–20%
Intermittent work (not continuous): +20–40%
Crew Composition
All journeyworkers: baseline
Mixed journeyworker/apprentice: −10–15% productivity
All apprentices: −30–40% productivity
Learning Curve
Familiar equipment: baseline
New equipment type: +10–20%
Specialized or complex equipment: +20–40%
An important note on crew composition: with 92% of contractors struggling to hire and apprentice-heavy crews becoming the norm, the productivity hit from mixed crews is no longer a theoretical modifier. For many contractors right now, it's the base case. Construction employment reached approximately 8.31 million in early 2026, yet hiring difficulty remains widespread, and skill requirements continue to intensify.
How to Apply This: Three Scenarios Worth Examining
1. The Estimate That Looks Right — Until It Isn't
You're bidding on a 100-ton chiller retrofit in an existing, occupied historic building. Your crew is working with this chiller model for the first time.
Start with the benchmark: 120 hours for a 100-ton retrofit in an existing building.
Apply the modifiers:
Occupied building: +15% → +18 hours
Historic structure with limited floor space: +20% → +24 hours
First time with this specific chiller model: +15% → +18 hours
Adjusted estimate: 180 hours.
If you bid 120 hours and encounter 180, you've absorbed 60 hours of unplanned labor at $65/hour — a $3,900 hit on a single line item. Multiply that across three or four scope items on the same job, and you're not losing margin. You're losing the project.
The modifiers aren't a guess. They're the record of what happened last time.
2. The Schedule That Creates Its Own Problems
You're planning an HVAC retrofit: two 5-ton rooftop units, 400 LF of standard ductwork, connections, and startup.
Two rooftop units, existing building: 44 hours
400 LF ductwork, standard routing: 22 hours
Connections and startup: 8 hours
Total: 74 hours ≈ 18 crew-days at a four-person crew
Realistic schedule with weather, trade coordination, and inspections: 4.5 weeks.
A PM under pressure often compresses this to three weeks. What happens next is predictable: reduced efficiency, more rework, crew fatigue, and a schedule penalty that shows up in final labor cost, costing more than the time you thought you were saving. The data is the argument you need to have that conversation before it becomes a problem.
3. The Subcontractor Bid That Looks Too Good
Two contractors quote the same scope:
Contractor A: 40 hours labor
Contractor B: 58 hours labor
Benchmark range: 50–65 hours
Contractor A is meaningfully below benchmark. That's either extraordinary efficiency — possible, worth verifying — or underestimated scope. Unhappy subcontractors don't just cost you money on this job. They generate change orders, slow down, and damage relationships with GCs you've spent years building.
Contractor B is inside the window. That's a credible number.
Benchmarks give you a lens for evaluating quotes, not just producing them. That's an underused advantage.
Regional Reality Check
These benchmarks reflect national averages. Your market may look different.
High-cost markets (Bay Area, NYC, LA, Boston): Labor rates run 20–30% above the national average. Productivity tends to run 5–10% lower due to union requirements, regulatory complexity, and the challenges of older building stock. Plan for actuals at the higher end of every range.
Lower-cost markets (South, rural Midwest): Labor rates are 20–30% below average, and productivity is 5–10% higher. Actuals tend toward the lower end.
Union vs. non-union: Union shops typically carry 10–20% lower hours-per-dollar productivity due to work rules. Non-union shops are generally faster but may have less training depth on complex systems — a trade-off that matters more as project complexity increases.
Your actual productivity will land 10–20% better or worse than these benchmarks, depending on where you operate and how your crews are structured. The benchmarks tell you where to start. Your own data tells you where you actually are.

The Compounding Advantage Most Contractors Never Build
Industry benchmarks are a starting point. Your own data — properly tracked — is worth far more. And it's more achievable than most contractors think.
The mechanism is simple: track actual hours at the activity level, compare against your estimates, and close the loop after every project. After two to three years of consistent tracking, you have a proprietary database calibrated to your specific crews, your region, and your typical project profile.
"Be aware where our profitability is coming from," said Sheryl Creech of Creech's Plumbing and Septic. "I feel like now we've got a good year with the data to be able to look at, and now we can start comparing month over month, year over year — where before we didn't have anything to compare it to."
That's the shift. Not just having data, but having your data, in context, over time.
Each closed project makes the next estimate sharper. Your bids become more competitive on jobs you should win — and more accurate on jobs you'd otherwise underprice and lose margin on. Contractors who build this discipline are compounding knowledge every year.
If your current actuals run 20% worse than these benchmarks — common for contractors without systematic measurement — you're leaving $200,000 to $400,000 on the table annually, depending on volume. Closing that gap doesn't require new equipment or a larger crew. It requires better planning, better sequencing, the right crew composition for each task, and materials staged before the crew arrives.
Start with one project type. Track it. Close the loop. The compounding starts immediately.
