Lookahead schedules and weekly work plans serve different but connected purposes in construction planning. The rolling lookahead schedule provides the medium-term view and make-ready process; the weekly work plan captures specific commitments for immediate execution. Understanding how these connect—and using weekly work plan construction practices effectively—creates a complete planning system that delivers reliable execution.
Different Time Horizons
Each serves a different horizon:
Lookahead horizon: The 3 week lookahead schedule, 4 week lookahead schedule, or 6 week lookahead schedule shows work over multiple weeks.
Weekly horizon: Weekly work plan construction focuses on the immediate week's work.
Connection: This week's work plan draws from the lookahead schedule software near-term activities.
Make-Ready to Commitment
Activities flow from lookahead to weekly plan:
Make-ready: Activities in the rolling lookahead schedule make-ready weeks have constraints resolved.
Commitment eligibility: Only constraint-resolved activities from construction lookahead software become eligible for weekly commitment.
Weekly commitment: Weekly work plan construction selects from ready activities for this week's commitments.
Last Planner Context
Last planner system software connects these elements:
Phase scheduling: Milestone-driven overall planning.
Lookahead planning: Lookahead schedule software provides the make-ready window.
Weekly work planning: Weekly work plan construction captures specific commitments.
Daily coordination: Daily execution of weekly commitments.
Weekly Work Plan Content
Weekly work plans include:
Specific commitments: Last planner system software captures what will be completed this week.
Responsible parties: Construction software documents who commits to each activity.
Prerequisites confirmed: Lookahead schedule software verification that prerequisites are met.
Resources allocated: Crew scheduling software construction resources assigned.
Commitment Standards
Commitments must meet standards:
Constraint-free: Activities in weekly work plan construction must have constraints resolved.
Achievable scope: Construction schedule app commitments must be achievable in the week.
Clear completion: Lookahead schedule software commitments have clear completion criteria.
The Planning Meeting
Weekly planning meetings connect lookahead and work plan:
Lookahead review: Review rolling lookahead schedule status and make-ready progress.
Commitment review: Review last week's last planner system software commitments and completion.
New commitments: Make this week's weekly work plan construction commitments.
Constraint identification: Identify construction lookahead software constraints for upcoming activities.
Foreman Role
Foreman scheduling app connects foremen to both:
Lookahead input: Foremen provide input on construction schedule app activity planning.
Commitment making: Foremen make weekly work plan construction commitments for their crews.
Execution: Foremen execute using foreman scheduling app guidance.
Subcontractor Coordination
Subcontractor management software connects trades to both:
Lookahead visibility: Subcontractors see upcoming work in rolling lookahead schedule.
Commitment participation: Subcontractor foremen participate in weekly work plan construction.
Coordination: Subcontractor management software coordinates trade commitments.
PPC Measurement
Last planner system software measures commitment reliability:
Commitment tracking: Weekly work plan construction commitments are tracked.
Completion assessment: Construction software assesses whether commitments completed.
PPC calculation: Last planner system software calculates Percent Plan Complete.
Variance Analysis
When commitments fail, analyze why:
Reason categories: Construction lookahead software categorizes variance reasons.
Root cause: Was the lookahead schedule software make-ready process inadequate?
Improvement action: Weekly work plan construction process improves based on analysis.
Technology Integration
Integrate lookahead and weekly work plan in technology:
Single system: Construction schedule app should support both lookahead and weekly work plan.
Activity flow: Lookahead schedule software activities should flow to weekly work plan.
Status connection: Construction software weekly completion updates lookahead status.
Crew Scheduling Connection
Crew scheduling software construction connects to both:
Lookahead capacity: Rolling lookahead schedule shows upcoming crew needs.
Weekly assignment: Weekly work plan construction assigns specific crews.
Daily execution: Foreman scheduling app guides daily crew work.
Common Mistakes
Avoid these coordination errors:
Commitment without make-ready: Making weekly work plan construction commitments without lookahead schedule software constraint resolution.
Disconnected systems: Using separate systems for construction schedule app lookahead and weekly work plan.
Skipping analysis: Not analyzing last planner system software variances for improvement.
Field Management Integration
Field management software supports both:
Lookahead updates: Field management software captures lookahead progress.
Commitment tracking: Construction schedule app tracks weekly commitment completion.
Daily coordination: Field management software supports daily execution of weekly plan.
Implementation Steps
Connect lookahead and weekly work plan:
Establish make-ready: Implement lookahead schedule software constraint management.
Create weekly process: Establish weekly work plan construction meeting and commitment process.
Track PPC: Implement last planner system software PPC tracking.
Analyze and improve: Use construction lookahead software data to drive improvement.
Conclusion
The rolling lookahead schedule and weekly work plan construction are complementary elements of effective construction planning. Lookahead provides the make-ready window; weekly work plan captures commitments for execution.
Last planner system software connects these elements in a complete planning system. Lookahead schedule software ensures work is ready; weekly work plan construction creates reliable commitments; tracking and analysis drive improvement.
Implement both elements together for reliable construction execution.
