📅 Schedule Management Guide

The schedule is your roadmap. If you're not managing it actively, you're just hoping the project finishes on time.

The Schedule Is a Tool

Use it or lose it. A schedule that sits in a drawer isn't managing anything.

Schedule Fundamentals

Types of Schedules

Type	Purpose	Update Frequency
Master Schedule	Overall project timeline	Monthly
Phase Schedule	Major phase detail	Bi-weekly
3-Week Lookahead	Near-term coordination	Weekly
Daily Plan	Day's activities	Daily

Schedule Elements

Activities:

• Discrete work tasks
• Defined duration
• Assigned resources
• Clear start/finish

Dependencies:

• Finish-to-Start (most common)
• Start-to-Start
• Finish-to-Finish
• Start-to-Finish (rare)

Milestones:

• Contract milestones
• Owner requirements
• Inspections
• Substantial completion

CPM Scheduling

Critical Path Method

The critical path is the longest sequence of dependent activities — it determines project duration.

Key terms:

• Float/Slack — Time an activity can slip without delaying project
• Critical Path — Activities with zero float
• Near-Critical — Activities with minimal float (watch closely)

Why Critical Path Matters

• Identifies what drives completion
• Shows where delays hurt most
• Focuses management attention
• Required for delay claims

Reading a CPM Schedule

Look for:

• Critical path (usually highlighted)
• Float on non-critical activities
• Logic ties between activities
• Milestones and constraints

3-Week Lookahead

The most useful day-to-day tool.

Creating a Lookahead

1. Pull activities from master schedule
2. Add detail for next 3 weeks
3. Break into daily/weekly tasks
4. Assign crews and resources
5. Identify constraints and prerequisites

Weekly Lookahead Meeting

Attendees: Super, foremen, key subs

Agenda:

• Review last week (planned vs. actual)
• Walk through next 3 weeks
• Identify constraints and blockers
• Assign responsibilities
• Document commitments

Making Lookaheads Work

✅ Do:

• Update every week
• Be realistic about durations
• Include procurement and inspections
• Track actual vs. planned
• Hold people accountable

❌ Don't:

• Copy master schedule verbatim
• Ignore prerequisites
• Over-commit resources
• Skip the meeting when busy

Schedule Updates

Monthly Update Process

1. Record actual start/finish dates
2. Assess remaining duration
3. Update logic if changed
4. Recalculate schedule
5. Compare to baseline
6. Report to owner

What to Update

• Actual dates for completed work
• Revised durations for in-progress
• New activities (change orders)
• Logic changes
• Resource adjustments

Baseline vs. Current

Baseline: Original approved schedule (frozen)

Current: Updated schedule with actuals

Variance: Difference between them (early/late)

Always maintain baseline for comparison.

Delay Management

Types of Delays

Type	Responsibility	Entitlement
Excusable-Compensable	Owner-caused	Time + money
Excusable-Non-Compensable	Neither party (weather)	Time only
Non-Excusable	Contractor-caused	Nothing
Concurrent	Both parties	Complex analysis

Documenting Delays

When a delay occurs:

1. Identify the cause
2. Document with photos and reports
3. Quantify the impact
4. Send written notice per contract
5. Update schedule to show impact

Notice Requirements

Most contracts require prompt notice:

• Read your contract's notice clause
• Send written notice immediately
• Don't wait to quantify cost
• Reserve rights in writing

Resource Management

Labor Loading

• Match crews to schedule
• Identify peaks and valleys
• Plan for overtime or double shifts
• Coordinate with subcontractors

Equipment Planning

• Major equipment tied to schedule
• Lead time for rentals
• Crane picks coordinated
• Mob/demob timing

Material Procurement

• Link submittals to schedule
• Long-lead items tracked
• Delivery coordinated with work
• Storage planned

Schedule Tools

Software Options

Tool	Best For
P6	Large/complex projects
MS Project	Mid-size projects
Smartsheet	Collaborative planning
Buildingconnected	Subcontractor scheduling
Excel	Simple schedules

Reporting

Weekly:

• 3-week lookahead
• Percent complete
• Issues and risks

Monthly:

• Schedule narrative
• Critical path status
• Variance analysis
• Recovery plan (if behind)

Common Mistakes

❌ Overly optimistic durations — Be realistic

❌ Ignoring float — Float belongs to the project

❌ Not updating regularly — Stale schedule is useless

❌ Missing logic ties — Activities float randomly

❌ No baseline — Can't measure variance

❌ Weather ignored — Build in realistic weather days
