Use a capacity-constrained portfolio process, not a first-come, first-served queue. First remove or re-scope projects that cannot be delivered with credible permits, designs, materials, site access and contractor capacity. Then rank the projects that pass that gate by deadline consequence, safety and public-service impact, readiness, scarce-trade demand, strategic value and delay risk. Plot every project’s crew and material demand by month, move lower-consequence work away from peaks, and phase separable work when the contract permits. Recheck the entire pipeline weekly for exceptions and monthly against actual starts, contractor loading, materials, permits, cost movement and schedule variance.
Why an overbooked contractor market requires portfolio prioritisation
When every contractor is busy, the decision is not simply which project has the earliest requested start date. It is which combination of projects can be delivered with the people, plant, materials, approvals and contract windows actually available, while protecting safety, statutory obligations and essential services.

A project that appears urgent but has an immature design, no permit, an unavailable specialist component or no credible crew slot is not ready to consume capacity. Starting it on paper can crowd out a project that is ready and consequential, then create claims, remobilisation costs and missed dates across the programme.

Infrastructure Australia reported a major public infrastructure pipeline worth $230 billion over five years in 2023, while identifying skills shortages, non-labour supply constraints and stagnant productivity as capacity constraints. That figure is Australia-specific and describes the reported public pipeline; it is not a forecast for every market or a productivity guarantee.
#1 Best Overall
US Federal Acquisition Regulation (FAR) 11.402 gives a defensible basis for the method. It says that, when setting a construction contract’s completion time, the contracting officer should consider the project’s nature and complexity, required completion date, material and equipment availability, contractor capacity and the use of multiple completion dates. That is a stronger foundation than rewarding whichever project entered the queue first.
Start with one pipeline register
Put every proposed, approved and active project in one register owned by a portfolio manager or programme office. Separate departmental lists hide collisions: two projects may each look reasonable in isolation while demanding the same roofing crew, crane, commissioning specialist or factory production slot in the same month.
| Register field | What to record | Decision it supports |
|---|---|---|
| Project and owner | Unique name, location, accountable sponsor and delivery manager | Prevents duplicate entries and makes escalation ownership clear |
| Safety and public-service impact | Life-safety exposure, regulatory risk, service interruption and affected users | Identifies consequences that should outweigh convenience or lobbying |
| Contractual or statutory deadline | Fixed date, event-linked date, liquidated-damages exposure and flexibility | Distinguishes a real deadline from an aspirational target |
| Scope, duration and separability | Estimated working duration, critical path, independent work packages and possible completion milestones | Shows whether work can be phased or packaged differently |
| Readiness status | Design maturity, approvals, survey information, site access, procurement status and contract route | Stops an unready project consuming a nominal contractor slot |
| Required trades and equipment | Trade types, specialist subcontractors, major plant and peak crew size | Enables trade-by-trade capacity loading |
| Long-lead items | Specification, supplier, order status, manufacturing and shipping window | Exposes material constraints before a start date is promised |
| Budget confidence | Estimate maturity, approved funding, contingency and likely price movement | Separates fundable work from a project likely to pause for money |
| Delay consequence | Service, revenue, safety, legal, reputational and interface effects of a late finish | Provides the basis for a consistent priority score |
| Contractor slot | Named contractor or market route, proposed start window, confirmed capacity and assumptions | Reveals whether the date is evidence-based or merely requested |
At minimum, record an approximate start and completion date for each pay item, the equipment expected to be used and the number of workers. That minimum schedule is recommended in CIAP guidance and gives an owner enough information to call a joint review when slippage appears. Use ranges when precision is not justified, but do not leave resource fields blank.

Do not let a high score compensate for a project that cannot start responsibly. Mark each project ready, conditionally ready or hold against the following checks.
Design and specification
- Required design packages are issued to a level that supports pricing and construction.
- Interfaces with utilities, adjacent projects and operations are understood.
- Any proposed design or technology change has been assessed for programme, cost and maintainability.
Approvals and access
- Planning, environmental, traffic, utility and building approvals are obtained or have a credible decision date.
- The owner controls the site or has a documented access agreement.
- Surveys, investigations, permits to work and enabling activities are complete enough to avoid an immediate stop.
Materials, plant and labour
- Long-lead components have a supplier, specification and realistic delivery window.
- Required plant and specialist trades are available in the proposed period, not merely somewhere in the contractor’s annual plan.
- Substitutions, local alternatives or resequencing options have been assessed where supply is uncertain.
Commercial and funding readiness
- Funding, estimate confidence, contingency and procurement route are approved.
- The contract allocates design, inflation, supply and interface risks to parties able to manage them.
- The payment model does not create an avoidable cash-flow or mobilisation barrier.
Scottish Government guidance recommends assuring that pipeline projects remain deliverable in programme, cost and specification when materials, plant or labour are constrained. It specifically points to reviewing design and technology, material and component availability, procurement and risk-transfer strategy and payment model before proceeding. A hold is a control, not a failure: it preserves the option to improve readiness instead of consuming scarce capacity with a stop-start project.
Score the projects that pass the gate
Use a weighted score so that different projects are compared on the same facts. The following starting weights total 100 percent:
| Criterion | Weight | How to assess it |
|---|---|---|
| Deadline consequence | 25% | Score the effect of missing a fixed statutory, contractual, funding or event-linked date; distinguish severe consequences from a preferred date. |
| Safety and service impact | 20% | Score life-safety exposure, critical-service interruption and the number or vulnerability of people affected. |
| Readiness confidence | 15% | Score evidence that design, approvals, access, procurement and funding will remain ready through mobilisation. |
| Scarce-trade and equipment demand | 15% | Score how heavily the project uses trades, plant or suppliers that are already constrained in the portfolio. |
| Value or strategic importance | 15% | Score approved strategic, operational, economic or community value, using the owner’s published objectives. |
| Delay and price risk | 10% | Score the likelihood and consequence of escalation, disruption, rework, claims or further supply delay. |
Rate each criterion on a common scale, such as 0 to 5, multiply by its weight and add the results. Adjust the weights when the owner’s objectives require it, but document who approved the change, why it was made and which projects it affects. Never alter weights quietly to produce a preferred ranking.
Illustrative scoring example
The numbers below are an example of the method, not a market benchmark. Scores are on a 0–5 scale; the weighted result is the score divided by five and multiplied by the criterion weight.
| Project | Deadline | Safety/service | Readiness | Scarce resources | Value | Delay/price risk | Weighted result |
|---|---|---|---|---|---|---|---|
| Project A: critical facility repair | 5 | 5 | 4 | 4 | 3 | 3 | 4.20/5 |
| Project B: service expansion | 3 | 4 | 5 | 2 | 5 | 4 | 3.75/5 |
| Project C: discretionary upgrade | 2 | 2 | 3 | 5 | 3 | 2 | 2.65/5 |
Project A ranks first, but the ranking is not the final schedule. If A and C both need the same specialist crew in the same month, moving C may release a slot for A. If A lacks an approval, it remains on hold until that gate is cleared, even with the highest score.
Plot demand by trade, equipment and month
Convert each project’s schedule into a demand view. For every month or week, show peak workers and plant by trade, contractor, work package and location. Include manufacturing and delivery windows for materials that can stop the work.
Find collisions
- Mark months in which two or more projects require the same contractor or specialist subcontractor.
- Mark shared cranes, piling rigs, testing teams, commissioning engineers, traffic-management crews and other difficult-to-replace resources.
- Mark material windows in which projects compete for the same factory capacity or shipping route.
- Compare the requested start with the contractor’s confirmed workload, not with a sales estimate or an unapproved baseline.
The Victorian Auditor-General’s Office found that separate investment decisions produced “un-strategic scheduling” and that agencies did not use cross-pipeline scheduling to even out peaks and troughs or reduce competition for resources. The practical lesson is to manage one demand curve. A lower-consequence project shifted by a few weeks can sometimes remove a peak that would otherwise delay several projects.

A quiet site or a slow pay item does not automatically mean the contractor is under-resourced. FHWA guidance identifies weather limits, curing times, late materials, excessive contract time and poor contractor scheduling as different causes of apparent inactivity. Record the actual constraint, its evidence and the earliest credible recovery date before moving a project up or down the queue.
Choose the right delivery tactic
| Tactic | Use it when | Controls to require |
|---|---|---|
| Start now | The project passes the gate, has a credible contractor slot and its score and capacity fit justify immediate mobilisation. | Confirm labour, plant, materials, permits, baseline and reporting dates before issuing a promise. |
| Reserve a future slot | The project is ready enough to protect a contractor window but another project has a stronger immediate consequence. | Set a reservation expiry, required readiness milestones and a recheck date; do not describe the slot as a start. |
| Phase separable work | Enabling works, buildings, utilities or commissioning can finish independently without creating unsafe or unusable partial assets. | Define interfaces, acceptance criteria, payment points, temporary works and separate completion dates. |
| Re-scope or redesign | A specification, technology or finish is creating a scarce material, specialist-trade or long-lead bottleneck. | Assess whole-life performance, approvals, cost, procurement and future maintenance before approval. |
| Package differently | A single contract concentrates demand or a different trade package could use available capacity. | Check interface risk, design responsibility, insurance, warranties, safety coordination and procurement rules. |
| Defer | Delay has lower consequences than the disruption, cost or risk of forcing the project into an overloaded period. | Record the trigger for reconsideration, protect approvals and preserve critical information and materials. |
FAR 11.402 expressly recognises multiple completion dates for separable items. Use that flexibility only where each phase has a safe, usable outcome and the contract clearly states what constitutes completion. Phasing is not a way to hide an unworkable plan; it is a way to align independent outcomes with real capacity.
Resolve two-project conflicts consistently
When two projects compete for one slot, compare them in this order:
- Deadline and consequence: What happens, specifically, if each project finishes later?
- Safety and service: Which project reduces a greater life-safety exposure or protects a more critical service?
- Readiness: Which project can mobilise without creating a predictable stop for design, permits, access or materials?
- Scarce-resource intensity: Which project consumes the constrained trade, plant or supplier for longer, and can either demand be moved?
- Cost and duration confidence: Which baseline is supported by better information, and which is more exposed to escalation or rework?
- Phasing potential: Can one project deliver an independent benefit in stages?
- Released capacity: Would moving one project free a constrained slot for a higher-impact project elsewhere in the portfolio?
Use the weighted score as the default. An executive may override it for a documented legal, safety, funding or public-interest reason, but the override should state the decision-maker, evidence, duration and review date. A hidden override destroys confidence in the process and encourages every sponsor to escalate.
Rank #4
Run a weekly exception review
Do not re-rank every project from scratch every week. Review exceptions that could change a project’s gate, score or capacity position.
- Compare each active contractor’s reported workload with the agreed resource plan.
- Check material lead times, supplier notices, substitutions and delivery confirmations.
- Check permits, design releases, site access and utility interfaces.
- Compare planned and actual starts, pay-item progress, crew loading and forecast completion.
- Ask the contractor to identify the cause of slippage, current resource allocation, affected activities and a dated recovery plan.
- Decide whether to resequence, add resources, phase work, grant contractual relief or change portfolio priority.
- Record the decision, evidence, owner and next review date in the register.
CIAP guidance supports a joint review when slippage occurs and allows an owner, where the contract permits, to require a catch-up schedule. A catch-up request should be specific: activities to recover, additional or reallocated resources, revised dates, assumptions and the evidence that the plan is achievable. Do not grant schedule relief solely because a contractor says the market is busy; establish the actual cause and contractual entitlement.
Reforecast the whole portfolio each month
A weekly review controls exceptions; a monthly reforecast tests whether the portfolio still fits reality. Compare:
- planned versus actual starts and completions;
- planned versus actual peak crew loading by trade and contractor;
- material lead-time movement and unfilled purchase orders;
- estimate, approved budget, commitments, forecast final cost and contingency;
- permit and design milestone confidence;
- schedule variance, forecast completion and confidence in each date;
- the number of projects held, resequenced, phased, re-scoped or deferred.
Publish the assumptions behind every priority change. Include the old and new rank, the changed fact, the decision-maker and the next trigger for review. This creates an audit trail and lets sponsors distinguish a changed priority from poor delivery.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
Stop promising dates that capacity cannot support
Use date categories
- Target date: an internal objective used for planning, not a contractor commitment.
- Conditional date: achievable only if named approvals, materials, funding and contractor capacity are secured by stated dates.
- Committed date: supported by an executed contract, accepted baseline, confirmed resources and identified assumptions.
Every external date should show its basis and the conditions that could move it. Say which contractor slot was confirmed, which materials are ordered, which approvals remain open and how much float exists. If a date depends on a contractor completing another project, show that predecessor and its confidence rather than presenting the date as independent.
Best Value
Use a reservation rather than a promise
For a project that is nearly ready but cannot start immediately, reserve a future window with an expiry date and readiness milestones. A reservation protects planning attention without creating the false expectation that work will begin regardless of permits, design or supply. Release the slot if the milestones are missed, then offer it to the next deliverable project under the documented rules.
Worked portfolio example
Assume three ready projects share one specialist contractor. Project A is a safety-critical repair with a fixed service deadline. Project B expands capacity and has complete design and approvals. Project C is a discretionary upgrade that uses the same specialist for a longer period but has a flexible completion date.
- Start A in the contractor’s next credible slot because its deadline and safety consequence dominate.
- Reserve B’s subsequent slot and release procurement for its long-lead items so the contractor can mobilise without a new delay.
- Move C outside the peak, or phase its independent enabling work with a different package if that does not create unsafe interfaces.
- Recheck the plan weekly. If A’s material delivery slips, do not automatically pull C forward; first test whether B is more ready and whether the shift would worsen the specialist-trade peak.
The point is not that safety-critical projects always win. The point is that the decision is visible: consequence, readiness, resource collision and phasing are compared together, and the schedule is changed when evidence changes.
Common failure modes and their fixes
| Failure mode | Why it fails | Fix |
|---|---|---|
| First-come, first-served queue | Rewards submission order rather than consequence, readiness or capacity fit. | Use the deliverability gate and weighted score. |
| Separate project schedules | Hides collisions for shared trades, plant and suppliers. | Maintain one portfolio register and a trade-by-month demand view. |
| Ranking before readiness | A high-value project consumes attention despite missing approvals or materials. | Hold it until the gate evidence is credible. |
| Nominal contractor availability | A contractor appears available because its schedule omits subcontractors, plant or manufacturing constraints. | Validate peak workers, equipment, subcontractors and material windows. |
| Moving work without diagnosing delay | Weather, curing, late materials or contract float may be mistaken for poor performance. | Establish the actual constraint and request evidence and a recovery plan. |
| Phasing without usable outcomes | Creates stranded assets, unsafe interfaces or duplicate mobilisation. | Define separable scope, acceptance criteria, interfaces and completion dates in the contract. |
| Unrecorded executive overrides | Encourages escalation and makes priorities impossible to defend. | Document the reason, evidence, approver and review date. |
| Fixed annual priorities | Ignores changes in contractor workload, supply and approvals. | Run weekly exception reviews and a monthly portfolio reforecast. |
What the process requires
This method does not require sophisticated software. It requires one authoritative register, a schedule that includes resources, a consistent scoring sheet, a demand view by trade and month, and decision rights that are understood by sponsors, procurement, delivery teams and contractors. A spreadsheet can work for a small portfolio if it is version-controlled and maintained; larger programmes need a shared capacity view so that changes are visible immediately.
Set the rules before projects compete: who owns the register, who can change weights, what evidence makes a project ready, who may approve an override, how contractor capacity is confirmed and how often the portfolio is reforecast. Local procurement rules, contract clauses and market conditions still govern the final decision. Contractor availability, material lead times, labour rates, software features and commercial terms can change quickly, so validate them again before applying a priority decision to a live project.
Official guidance explains why capacity and sequencing matter, but it does not establish a general percentage productivity uplift attributable to one prioritisation method. Measure your own results through start-date reliability, peak-resource reduction, schedule variance, cost movement, claims and completed service outcomes rather than promising an unsupported improvement.
A practical first-week checklist
- Export every proposed, approved and active project into one register.
- Add deadline consequence, safety and service impact, readiness, trades, peak workers, plant, materials, permits, budget confidence and delay consequence.
- Place every project behind a ready, conditional or hold gate.
- Score the ready set with the six weighted criteria and publish the assumptions.
- Plot contractor, trade, plant and material demand by month.
- Identify collisions and test start-now, reserve, phase, re-scope, repackage and defer options.
- Publish conditional and committed dates separately.
- Schedule the weekly exception review and monthly portfolio reforecast.
- Require evidence and a dated catch-up schedule before changing priority or granting relief.
- Keep a written record of every override and the trigger for revisiting it.
This creates a queue that contractors can actually deliver: readiness first, consequence next, and capacity visible throughout the decision.
