Subcontractor Coordination for General Contracting

Ask the project manager for the list of awarded subcontractors and any contact details already on file. Start your list with the company name, scope, and main contract number or identifier.

For each subcontractor, request the name, mobile number, and email for their on-site foreman, project manager, and at least one escalation contact (such as an operations manager). Confirm who should be called first for day-to-day issues.

Create a simple contact log or sheet with columns for trade, company, scope, and each contact’s details. Keep the format easy to scan quickly when you need a number on short notice.

Send the draft list to each subcontractor and ask them to confirm or correct the information. Make necessary updates so you are not relying on outdated numbers or names.

Save the contact list in a shared digital location and print a copy for the job trailer. Let superintendents, project engineers, and key foremen know where it is and that it should be used for all coordination.

Every few weeks, or when you hear about personnel changes, review the list and update any changed contacts. Remove people who are no longer on the project so you do not accidentally call the wrong person.

Create a one- or two-page document that summarizes working hours, check-in procedures, parking rules, laydown policies, safety PPE requirements, clean-up expectations, and any special rules (like noise restrictions). Use simple bullet points so it’s easy to read.

Before each new subcontractor mobilizes, hold a quick pre-start meeting or call with their project manager and foreman. Walk them through the site information sheet and answer questions.

Describe how materials will enter the site, where deliveries can park, how hoists or elevators are scheduled, and which areas are off limits. Make it clear how far in advance they must request special access or crane time.

Tell subcontractors exactly when they can start noisy work, when the site closes, and what approvals are needed for early, late, or weekend work. Confirm they will schedule their crews accordingly.

Be very direct about cleanup responsibilities, waste disposal locations, and safety rules that are non-negotiable. Explain what will happen if they do not follow these rules (for example, fines, backcharges, or work stoppage).

Email the site information sheet to subcontractor office contacts and foremen, and keep printed copies in the job trailer. Refer back to this document in future conversations when enforcing expectations.

Before the weekly meeting, generate or update a lookahead schedule that lists planned activities by trade and area for the next 2–3 weeks. Highlight critical path work and key milestones.

Email or otherwise distribute the lookahead to subcontractor foremen and project managers at least a day before the planning session. Ask them to review and think about crew sizes and constraints.

At a set time each week, meet with all active trade foremen (in person or virtually). Walk through the lookahead, area by area, and ask each trade what they can realistically complete each week.

For each trade and week, write down their specific commitments (for example, “frame 6 rooms on Level 2”) and any constraints they identify (missing materials, inspections, access issues). Challenge unrealistic promises gently until they are credible.

Discuss where one trade must finish before another starts. Agree on handoff dates and the minimum conditions that must be met (for example, “framing complete, inspected, and cleaned before rough-ins start”).

After the meeting, adjust the lookahead based on what was agreed. Distribute the updated lookahead and a summary of trade commitments to all participants so everyone sees the same plan.

Start with the daily work plan that outlines which trades should be working in which areas. Keep it handy as you check who actually arrived.

During or just after the morning huddle, ask each subcontractor foreman how many workers they have on site that day and when they expect any additional crew to arrive.

Check whether the number of workers present matches what was assumed in the weekly and daily plans. Note any big differences, especially for trades working on critical path tasks.

Have each foreman state their plan for the day in terms of specific areas and quantities (for example, “rough-in 3 apartments” rather than “keep roughing in”). This helps you see if their goals align with the project’s priorities.

If manpower is short, help foremen adjust their plan to focus on the most critical tasks. If manpower is higher than expected, see if you can pull work forward in coordination with other trades.

Write down daily headcounts and key tasks for each trade in a log or on the daily board. This log becomes useful for tracking performance and explaining schedule shifts later.

When a conflict arises, listen to each trade’s description of the problem. Clarify whether the issue is about space, access, noise, safety, or out-of-sequence work. Avoid reacting until you understand both sides.

Look at the current schedule, weekly lookahead, and any written commitments to see what was planned for that area and which trade has priority work there today.

Consider safety first: if one activity creates serious hazards for another, it may need to stop or be rescheduled. Also consider which sequence will best support overall productivity and quality.

Based on the plan and impacts, decide whether one trade should have exclusive access for a period, or whether a shared arrangement is possible (for example, morning vs. afternoon use of an area or hoist).

Explain your decision clearly to the affected foremen and why you chose that sequence. Reference the plan and safety considerations rather than personal preference to maintain fairness.

Write down what was agreed—who works where and when—and update the daily plan board if needed. This prevents confusion later in the day if people forget or new crew members arrive.

Identify which site elements are shared resources: man/material hoists, freight elevators, cranes, forklifts, stair towers, and major access corridors. Note who typically uses each.

Ask trades when they most need these resources (for example, morning material runs, afternoon trash removal). This helps you anticipate peak demand times and plan around them.

For each shared resource, set basic rules such as scheduled time blocks, “first hour for deliveries, second hour for trash,” or priority for certain trades at key times. Write these rules down.

Place a copy of the schedule and rules near the hoist, elevator, or other shared resource so operators and workers can see what is supposed to happen and when.

Designate a named person (often the superintendent or hoist operator) to manage real-time adjustments when conflicts occur. Make sure trades know who this is and that this person’s decision is final for that day.

If the same conflicts continue to happen, review the schedule and usage pattern. Adjust time windows, add more structure, or bring in additional equipment if justified by the workload.

Check your RFI log, change order log, and any architectural/engineer supplemental instructions issued since the prior day. Identify which trades and areas are affected.

For each change, write a short, plain-language summary (for example, “duct size increases from 16” to 20” on grid 4 between columns C and D”). Avoid relying only on technical language.

Talk directly with the foremen whose work is affected. Show them the official document (RFI answer, bulletin, sketch) and walk them through the summary of what is changing.

Ask specific questions to confirm they understand: what needs to change, what work must be stopped, and what needs to be reworked (if anything). Clarify any misunderstandings immediately.

Ensure that field drawings are updated or clearly marked with the change reference. Remove or mark old sheets as superseded so they are not accidentally used.

Make a short note in your daily log or coordination notes that you reviewed specific RFIs/changes with specific trades and when. This helps later if there is a dispute about who knew what and when.

During your regular site walks, specifically look at PPE use, fall protection, equipment operation, and cleanliness of work and access areas for each trade.

Mentally check what you see against the site rules and safety plan you communicated earlier. Note where a subcontractor is clearly meeting expectations and where they are falling short.

When you see a serious safety issue or very poor housekeeping, stop and correct it on the spot. Explain what is wrong and what must be done differently. Do not walk past it.

If the same trade repeatedly violates rules, start documenting dates, locations, and the specific conditions in a simple log. This record supports formal conversations later.

Share documented issues with the subcontractor’s project manager or higher-level contact. Explain that the problems are recurring and what outcomes you expect (for example, additional training, on-site supervision changes).

If a subcontractor continues to ignore safety or housekeeping requirements, consider adjusting their access, scheduling, or even temporarily stopping their work until issues are resolved, following company and contract procedures.

Over several weeks, note patterns for each subcontractor: do they staff appropriately, hit commitments, coordinate with others, and maintain quality? Record concrete examples rather than general impressions.

Review the original expectations discussed at pre-construction or kickoff meetings. See where the subcontractor is meeting, exceeding, or falling short compared to what was promised.

Write a brief summary (a few bullet points) highlighting strengths and concerns for each subcontractor. Focus on specific behaviors like “often late to hoist window” rather than personality.

Schedule a short meeting with the subcontractor’s foreman and, if performance issues are more serious, their project manager. Share your observations calmly, with examples and impact on the project.

Ask the subcontractor what they will change (crew size, supervision, planning, training) and agree on concrete actions and timeframes. Avoid vague commitments like “we’ll try harder.”

Monitor whether agreed changes actually happen and improve results. If not, escalate within your own company per standard procedures and with the subcontractor’s leadership, using your documented examples.

Create a log or use a shared document with columns for date, trade, topic, decision/commitment, responsible person, and due date. Keep it simple enough that you will actually use it.

After weekly lookahead meetings, conflict resolution talks, or major change discussions, enter the main decisions and commitments into the log while they are still fresh.

Write commitments as specific actions (for example, “ABC Mechanical to complete Level 2 rough-in by Friday 4/12”) instead of vague notes like “mechanical to push harder.”

When a decision affects multiple trades, send the relevant log entries or a brief summary to those trades so everyone has the same understanding of what was agreed.

At least weekly, filter the log for open commitments and follow up with the responsible subcontractors. Ask for status updates and adjust dates only if there is a clear, justified reason.

Bring the coordination log into monthly job reviews or post-project reviews as a reference. It will help explain schedule shifts, show where trades cooperated well, and highlight where processes need improvement.
