Project Management for Trades Reference

Why this matters

Project management is what turns "we did some work" into "we delivered a project on time, on budget, to spec." The basic disciplines - schedule, budget, quality, communication, risk - apply at every scale: a residential bathroom remodel, a commercial new construction, or a multi-million-dollar industrial install. Knowing these disciplines lets a tech grow into a foreman, project manager, or business owner.

The five PM disciplines

1. Scope

What's included and what isn't. Scope creep (work added without compensation) kills profitability.

Define scope upfront:

• Written contract / proposal
• Detailed list of inclusions
• Explicit exclusions
• Drawings / plans referenced
• Materials specifications

Manage scope changes:

• Change order process - every change requires a written, signed change order with cost and schedule impact
• Don't do work "while you're here" without authorization
• Educate the customer that change orders aren't punishment; they're how scope is maintained

2. Schedule

Schedule fundamentals:

• Critical path: the sequence of dependent tasks that determines the project end date
• Float: how much slack a non-critical task has
• Milestones: key delivery dates (rough inspection passed, drywall hung, CO obtained)
• Buffer: contingency time built into the schedule

Scheduling tools:

• Microsoft Project / Smartsheet (large projects)
• Google Sheets with Gantt template (small projects)
• Procore / Buildertrend (residential construction)
• Whiteboard (very small projects, daily standup)

Common scheduling mistakes:

• Over-promising completion dates to "win" the job
• Not adding buffer for inspections, weather, material delays
• Assuming subs/trades arrive when scheduled (they don't always)
• Not adjusting schedule when scope changes

3. Budget

Budget categories:

• Direct materials (parts, fixtures, equipment)
• Direct labor (tech hours × burdened rate)
• Subcontractor costs (if applicable)
• Equipment rental
• Permits and fees
• Allowances (specific items priced as line items but selected later)
• Contingency (10-15% typical for residential remodel; less for new construction)
• Overhead allocation
• Profit margin

Tracking:

• Compare actual to estimated weekly
• Identify variances early
• Trigger change orders for scope-driven overruns
• Adjust forecast as actuals come in

Common budget mistakes:

• Treating allowance as "we can absorb a 20% overrun on this item" rather than "this is the budget for the item"
• Skipping contingency on uncertain-scope work
• Not tracking labor hours per task
• Not separating materials from labor
• Eating change-order costs to "be a nice guy" - kills the project

4. Quality

Quality standards:

• Code compliance (the minimum)
• Manufacturer specifications
• Industry best practices (ACCA QI, NECA, MCAA)
• Customer expectations (sometimes higher than code)

Quality control:

• Self-inspection before each AHJ inspection
• Punch list for finished work
• Photographic documentation
• Independent inspection at milestones
• Final commissioning of equipment

Common quality mistakes:

• Hurrying through punch-list items
• Not testing systems before closing walls
• Skipping documentation
• Failing to verify with the customer that the work matches expectations

5. Communication and risk

Communication patterns:

• Daily huddle / progress update on the job
• Weekly status meeting with stakeholders (GC, owner, architect)
• Written documentation of decisions
• Issue logs and resolution tracking

Risk identification:

• What could delay this project? (weather, materials, inspections, sub availability, customer indecision)
• What could blow the budget? (scope creep, hidden conditions, material price changes)
• What could compromise quality? (rushing to deadline, untrained labor, supply substitutions)

Risk mitigation:

• Buffer schedule for known risks
• Lock in material prices when possible
• Get permits early
• Coordinate with other trades

A simple project plan template

For a 4-week residential remodel project:

Week 1: Demolition + rough-in

• Day 1-2: Demo, debris removal
• Day 3-4: Plumbing rough
• Day 5: Electrical rough

Week 2: Inspections + insulation

• Day 1: Mechanical inspection
• Day 2: Plumbing inspection
• Day 3: Electrical inspection
• Day 4-5: Insulation, drywall start

Week 3: Drywall + initial finish

• Day 1-3: Drywall hang, tape, mud
• Day 4: First coat paint
• Day 5: Cabinet installation

Week 4: Finish + punchlist

• Day 1-2: Trim, fixtures, final plumbing
• Day 3: Final electrical, fixtures
• Day 4: Touch-up paint, cleanup
• Day 5: Final inspection, customer walk-through, punchlist

This is a high-level view. Each task breaks down further into daily activities.

Contract types

Lump-sum (fixed-price):

• One total price for defined scope
• Risk on the contractor - overrun comes out of profit
• Customer gets predictable cost
• Most residential remodel work

Cost-plus:

• Cost of work + agreed-upon percentage markup
• Risk on the customer
• Works for unclear-scope projects
• Often used in custom luxury or unusual situations

Time and materials (T&M):

• Hourly rate × hours + materials at markup
• Risk on the customer
• For unclear-scope service work

Guaranteed maximum price (GMP):

• Cost-plus up to a cap
• Risk shared
• Used in commercial construction

Pick contract type based on scope clarity, customer relationship, and risk tolerance.

Subcontractor management

If you're a GC managing trades, OR a tech reporting to a GC:

Pre-engagement:

• Verify license, insurance (general liability, workers' comp, vehicle)
• Reference checks
• Capability verification (have they done similar work?)
• Contract - written agreement, scope, schedule, payment terms

During work:

• Daily check-ins
• Quality review at completion of each task
• Coordination with other trades
• Issue resolution process

Payment:

• Progressive payments tied to milestones
• Retention (5-10% held until punchlist complete)
• Final payment after CO and lien waivers

Common project failure modes

Schedule slips:

• Overpromised start dates
• No buffer for inspections / weather
• Material delays not communicated to customer
• Subs / trades not arriving when scheduled

Budget overruns:

• Scope creep without change orders
• Hidden conditions (rotted framing, asbestos, etc.) eaten by contractor
• Material price increases
• Labor overruns (took longer than estimated)

Quality issues:

• Untrained labor
• Rushed work to hit deadline
• Skipped testing / inspection steps
• Substitute materials not approved

Customer relationship breakdown:

• Surprise charges
• Communication gaps
• Unmet expectations
• Bad punch list management

Closeout - finishing well
