The Best KPIs for General Contractors in 2027

Why General Contractors Report Differently

A SaaS company can run on ARR, NRR, and CAC payback. A general contractor cannot — and the operators who try usually blow up inside two fiscal years. Construction revenue is recognized over time under ASC 606 percentage-of-completion, which means the GL is essentially an estimate until the punch list closes. Cost of revenue is dominated by subcontractor pass-through (50-65%) and direct materials (15-25%), both exposed to commodity swings and tariff shocks that hit hard in 2025-2026 and are still reverberating through 2027 backlogs.

General contractors live and die on three things SaaS founders never think about: project schedule, change-order discipline, and bonding capacity. A two-week schedule slip on a $40M commercial build can cost the GC its general conditions float for the rest of the job. A sloppy change-order trail turns a profitable project into a fee-funded one. A damaged surety relationship caps bondable revenue and freezes growth even when demand is hot. The CFMA Construction Financial Benchmarks Report, the ABC Construction Backlog Indicator, and the AGC Workforce Survey are the three datasets every GC CFO must read every quarter, and the most important KPIs below derive from those three.

There is also a 2027-specific labor problem driving every one of these KPIs. ABC's Construction Workforce Demand Forecast projects the industry needs 456,000 net new workers in 2027, up from 349,000 in 2026. Every KPI below — particularly Revenue per Field Employee, PSV, and TRIR — has to be read with that labor scarcity in mind.

The Most Important KPIs, In Depth

1. Gross Margin (Project & Company)

Definition: Revenue minus direct cost of construction (subs + materials + direct labor + equipment + bond), divided by revenue. Tracked at job level monthly and company-wide quarterly.

Formula: (Revenue - Direct Job Cost) / Revenue

2027 Benchmark: CFMA reports industry average gross margin of 14.8% for general contractors. Residential GCs run 18-25%, commercial GCs 10-20%, public/infrastructure 8-14%. Top-quartile commercial GCs in 2027 are clawing back to 16%+ despite tariff drag on steel, copper, and aluminum.

Named operator: Turner Construction (Hochtief subsidiary) reports operating margins in the 1.5-2.5% range on $17B+ revenue — that is *operating* margin; gross is materially higher in the 7-10% band for mega-GCs. DPR Construction runs a fee-plus-GC model that pushes effective gross margin closer to 12-15%.

Failure mode: Reporting gross margin including unbilled change orders that have not been signed. When the CO gets rejected at closeout, the margin was never real and the year's earnings have to be restated.

2. Project Schedule Variance (PSV)

Definition: Difference between planned and actual schedule progress, expressed as a percentage of the planned schedule, derived from earned-value methodology.

Formula: (Earned Value - Planned Value) / Planned Value

2027 Benchmark: Top-quartile commercial GCs hold PSV within +/- 5%. Median is roughly +/- 12%. Anything worse than -15% typically triggers a liquidated-damages exposure and a margin write-down at the next WIP cut.

Named operator: Suffolk Construction publicly credits its Smart Labor AI platform with cutting average PSV by 30%+ on its Boston commercial portfolio. Skanska USA uses VDC clash-detection workflows that compress PSV variance during the structural phase.

Failure mode: Updating the schedule monthly instead of weekly. By the time a monthly PSV report flags a problem, the float is gone and the recovery plan costs 3x what it would have cost in week one.

3. Change-Order Revenue Percentage

Definition: Approved change-order revenue divided by original contract value, tracked per project and rolled up at the portfolio level.

Formula: Approved CO Revenue / Original Contract Value

2027 Benchmark: Healthy band is 5-10% of original contract value. Renovation, infrastructure, and design-build routinely run 10-25% because of unknown conditions. Over 15% on new commercial ground-up construction is a yellow flag that estimating, scope definition, or owner expectation management has broken down.

Named operator: AECOM discloses backlog and change-order pipeline as part of its segment reporting; renovation-heavy federal work shows CO ratios above 15% routinely. Mortenson Construction reports CO ratios in the 6-9% range on its sports and healthcare new-builds — a model of disciplined scope freezes.

Failure mode: Performing change-order work on a verbal directive without a signed PCO. The cost hits the job; the revenue never does.

4. Subcontractor Cost Ratio

Definition: Total subcontractor cost divided by total project cost. The single largest line item in most commercial GC P&Ls.

Formula: Subcontractor Cost / Total Job Cost

2027 Benchmark: 50-65% of total contract value is the industry norm for commercial GCs. Self-perform GCs run 30-45%. Construction management at-risk (CMAR) firms run 70-80%. A sudden shift of +/- 5 points quarter-over-quarter is usually a leading indicator of sub default risk or scope creep.

Named operator: Whiting-Turner publicly emphasizes its self-perform concrete, steel, and MEP capabilities, holding its sub ratio closer to 45% versus the 65% typical pure-CM peer.

Failure mode: Failing to monitor sub financial health. A sub default mid-project costs the GC 2-4x the original sub contract value to rebuy and remobilize.

5. Backlog in Months

Definition: Signed contract revenue not yet earned, divided by trailing-twelve-month revenue, expressed in months.

Formula: Unearned Signed Revenue / (TTM Revenue / 12)

2027 Benchmark: The ABC Construction Backlog Indicator stood at 8.8 months in April 2026 and has held the 8.5-9.0 month range entering 2027. Data-center-attached contractors carry 10.6-12.2 months. Healthy floor is 6 months; below 4 months indicates pipeline collapse.

Named operator: Clayco and DPR both publicly carry 10+ months thanks to data-center and life-sciences exposure. Granite Construction runs a heavier 12-15 month civil/infrastructure backlog under public funding (IIJA tail spend).

Failure mode: Counting LOI volume in backlog. Only signed contracts with notice-to-proceed count. Anything else inflates the surety story and triggers a credibility hit when bonded backlog falls.

6. Working Capital Days (DSO + DIO - DPO)

Definition: How many days of revenue are tied up in receivables, retainage, and unbilled WIP, net of trade payables.

Formula: (DSO + DIO) - DPO

2027 Benchmark: 60-90 days is healthy. Over 120 days typically forces a credit-line draw or a hard equity injection. Retainage alone is 5-10% of every billing, often held 60-180 days past substantial completion.

Named operator: Tutor Perini publicly discloses material retainage and unbilled WIP balances — over $1B at trailing year-ends — illustrating how working capital binds a public GC's cash flow.

Failure mode: Letting retainage pile beyond 90 days post-closeout. Unrecovered retainage is the single most common cause of GC bankruptcy outside material price shocks.

7. Safety Total Recordable Incident Rate (TRIR)

Definition: OSHA recordable incidents per 200,000 worker-hours. Drives insurance premiums, EMR, and bondability.

Formula: (Recordable Incidents x 200,000) / Total Hours Worked

2027 Benchmark: Industry average TRIR is 2.4 per BLS construction-sector data; best-in-class commercial GCs hold below 0.75. An EMR above 1.0 disqualifies bids on most Class-A commercial and federal work.

Named operator: The Beck Group publicly reports a TRIR consistently below 1.0. Mortenson publishes an annual zero-incident campaign with TRIR tracked at every job huddle.

Failure mode: Counting only OSHA-recordables and ignoring near-miss reports. Near-miss volume is the leading indicator; TRIR is the lagging one.

8. Cash Conversion Cycle (Project-Level)

Definition: Days between paying subs and suppliers and collecting from the owner on the same project.

Formula: DIO + DSO - DPO

2027 Benchmark: Target under 45 days. Median commercial GC runs 60-75 days. Public-works GCs run 90-120 days because of slow government payment cycles. Pay-when-paid contract clauses are critical here in 2027 given continuing supplier pressure.

Named operator: Holder Construction uses front-loaded schedules-of-values and aggressive billing-cycle discipline to keep CCC under 30 days on private-sector commercial.

Failure mode: Paying subs net-30 while owners pay net-60 with 10% retainage. The GC effectively becomes the project's bank.

9. Revenue per Field Employee

Definition: Annual revenue divided by total field headcount (foremen, journeymen, apprentices, laborers).

Formula: Annual Revenue / Field Headcount

2027 Benchmark: $425k-$650k per field employee for commercial GCs. Self-perform civil contractors run $300-400k. Pure-CM firms run $900k+ because most labor is subcontracted. With ABC forecasting demand for 456,000 net new workers in 2027, this KPI is the single best proxy for labor leverage.

Named operator: Hensel Phelps reports revenue-per-employee in the $1.1M range across all employees (a CM-heavy figure); broken down to field-only, it runs closer to $650k.

Failure mode: Mixing field and office headcount in the denominator. The metric loses its operational signal and labor planning falls apart.

Real Operators

• Turner Construction — Hochtief subsidiary, ~$17B revenue, ~8% gross margin, ~1.8% operating margin, 9-10 month backlog, TRIR consistently below 1.0.
• Whiting-Turner — Private, ~$10B revenue, ~45% sub-cost ratio (heavy self-perform), publicly reports zero-incident days.
• DPR Construction — Employee-owned, ~$10B revenue, 12+ month data-center-heavy backlog, fee-plus model pushes effective margin to 12-15%.
• Suffolk Construction — Boston-based, ~$4B revenue, AI-driven PSV reduction of 30%+ through Smart Labor platform.
• Clayco — ~$5B revenue, data-center and industrial mix, 10-12 month backlog through 2027.
• Mortenson Construction — ~$5B revenue, ~7% change-order ratio, target TRIR below 1.0, sports/healthcare new-build focus.
• Granite Construction — Public civil contractor, 12-15 month backlog under IIJA tail spend.
• Tutor Perini — Public, $1B+ retainage on books, illustrates working-capital binding common to public-works GCs.

Failure Modes

1. Reporting margin on unsigned change orders. The CO gets rejected at closeout and the project loses 200-400 bps of margin that was already shown to the board.
2. Monthly schedule updates instead of weekly. Float is gone by the time the variance shows on a monthly report.
3. Counting LOI in backlog. Inflates the runway story and surprises the surety when bonded backlog falls.
4. Ignoring sub financial health. A sub default mid-project costs 2-4x rebuy and remobilization.
5. Letting retainage age past 90 days. Single most common cause of GC bankruptcy outside material shocks.
6. Mixing office and field headcount in revenue-per-employee. Kills the operational signal needed for labor planning against the 456,000-worker 2027 shortfall.

Reporting Cadence

• Daily: Safety leading indicators (near-miss, JHA compliance), field labor hours by cost code, daily field reports.
• Weekly: PSV per active project, weekly cost-to-complete (CTC), change-order log, billings/collections pipeline, sub-payment status.
• Monthly: Project-level gross margin (WIP schedule), sub-cost ratio, change-order revenue %, working capital days, cash conversion cycle, AR aging.
• Quarterly: Company-wide gross margin, backlog months, TRIR, EMR, revenue per field employee, bonding capacity utilization, CFMA benchmark comparison.

30 / 60 / 90 Day Implementation

Days 1-30 (Foundation): Rebuild the WIP schedule from raw GL. Standardize cost codes to CSI MasterFormat. Assign one accountable owner per KPI (PM owns PSV, PX owns margin, CFO owns CCC). Pull the most recent CFMA benchmark report for comparison and identify the three KPIs furthest from peer median.

Days 31-60 (Operationalize): Move PSV and CTC reviews to weekly cadence with PM-led 30-minute sessions. Implement digital change-order log with PCO-to-CO conversion tracking. Set up subcontractor financial health monitoring (default-risk scoring, lien-history lookup, payment-velocity flag).

Days 61-90 (Optimize): Stand up the quarterly CFMA-comparison dashboard. Wire bonding-capacity utilization to backlog forecast. Build the labor-leverage forecast against ABC's 2027 worker-demand projection. Run the first quarterly board read-out using all key KPIs against peer median.

FAQ

What is a good gross margin target for general contractors in 2027? A healthy gross margin typically falls between 14% and 16%. Some firms may see slightly higher margins on specialized work, but margin compression from material and labor cost pressures keeps most in that range.

How can I tell if my change-order revenue percentage is a problem? Change-order revenue that makes up 5% to 10% of total contract value is considered healthy. If it exceeds 15%, it often signals poor preconstruction planning or scope gaps that can erode profitability.

What does the backlog in months metric really mean for my business? Backlog in months measures how many months of future work you have under contract. The ABC Construction Backlog Indicator averaged around 8.8 months in mid-2027, but a healthy range for most contractors is roughly 6 to 10 months, depending on project size and market focus.

Why is subcontractor cost ratio important, and what should it be? This ratio shows how much of your contract value goes to subs. A typical range is 50% to 65%. Staying within that band helps ensure you’re not over-relying on subs (which can reduce control) or under-using them (which may mean you’re self-performing too much risk).

How often should I track these KPIs to stay competitive? Track project-level KPIs like schedule variance and change-order percentage weekly. Company-level metrics such as gross margin, backlog, and cash conversion cycle should be reviewed monthly to catch trends early.

What is a realistic safety TRIR target for a general contractor in 2027? Best-in-class firms aim for a Total Recordable Incident Rate below 0.75. Many contractors consider anything under 1.0 as strong, but continuous improvement toward that lower benchmark is common in safety-focused organizations.
