Create a Subcontractor Coordination Schedule

Generate a weekly subcontractor coordination schedule showing planned activities, access requirements, plant needs, and trade interdependencies.

IntermediateSite ManagerSubcontractor Management

Overview

This workflow helps Site Managers produce a structured weekly coordination schedule for managing multiple subcontractors on site. It maps out activities, resource requirements, and interdependencies to support effective short-term planning and daily briefings.

Prompt

You are a UK Site Manager preparing the weekly subcontractor coordination schedule for an active construction site. Generate a detailed coordination schedule using the following information:

Project Details:
- Project: [PROJECT NAME]
- Week Commencing: [DATE, e.g., Monday 10 March 2025]
- Current Phase: [PHASE, e.g., Superstructure to Blocks A & B, substructure to Block C]
- Site Working Hours: [HOURS, e.g., 07:30-17:30 Mon-Fri, 08:00-13:00 Sat]
- Tower Crane Available: [YES/NO, if yes note capacity and exclusion zones]

Subcontractors on Site This Week:
[LIST EACH SUBCONTRACTOR WITH DETAILS, e.g.,
- ABC Concrete Ltd — RC frame Block A Level 3 columns and slab pour, 8 operatives, requires crane, concrete pump Wed AM
- DEF Steel Ltd — Steelwork erection Block B, 6 operatives + 1 crane driver, requires crane priority Mon-Tue
- GHI M&E Services — First fix mechanical risers Block A Levels 1-2, 4 operatives, requires goods hoist access
- JKL Brickwork — External masonry Block A south elevation, 10 operatives + 2 labourers, scaffold required
- MNO Drylining — Metal stud partitions Block A Level 1, 6 operatives, materials delivery Tuesday
- PQR Groundworks — Drainage run Block C, 4 operatives + mini excavator, requires banksman]

Key Constraints:
[LIST, e.g., Concrete pour scheduled Wednesday requires road closure TMP in place, noise-sensitive school adjacent — no percussive works before 09:00, Block B crane out of service Thursday for maintenance]

Generate the coordination schedule as follows:

1. Weekly Overview Table — columns: Subcontractor, Package, Location/Zone, Planned Activity This Week, Labour Count, Key Plant/Equipment, Deliveries, Crane Time Required, Dependencies/Clashes

2. Daily Breakdown (Monday to Friday) — for each day show:
   - Crane allocation schedule (30-minute slots if applicable)
   - Goods hoist allocation
   - Concrete/material deliveries with times
   - Activities by zone to avoid clashes
   - Permit requirements (hot works, confined space, etc.)

3. Interdependencies & Sequencing — identify where one trade must complete before another can start and flag any potential clashes (e.g., "DEF Steel must complete Level 3 connections before ABC Concrete can fix slab reinforcement")

4. Access & Logistics — delivery vehicle schedule, road closure requirements, material storage allocation, skip/waste collection schedule

5. Safety Considerations — specific hazards this week, exclusion zones, any concurrent high-risk activities requiring additional supervision, toolbox talk topics

6. Key Decisions Required — items needing Site Manager or Project Manager decision this week

7. Look-Ahead (Following Week) — brief note on what is planned for the next week to enable advance coordination

Format each section clearly so it can be printed and used at the Monday morning subcontractor coordination meeting and updated daily.

Use Case

Use every Friday or Monday morning to prepare the weekly coordination schedule. Input the planned subcontractor activities and the AI will identify clashes, sequence activities, and produce a structured schedule for the coordination meeting.
