Scoping a Project Management Engagement for a Facility Expansion

A facility expansion is harder to scope than a new building. The site is occupied, the existing structure carries constraints that were never designed for what you are about to add, and operations have to continue while the work proceeds. Scoping the project management engagement is the first control an owner puts in place, and getting it wrong is expensive in a way that is difficult to reverse once design money has been spent.

Define the business case and success criteria before you define the building

Every expansion starts as an operating problem. The racking is full, the line cannot be extended, a tenant needs contiguous space, or the loading configuration limits truck movement on site. Write that problem down in operating terms before anyone draws anything. The business case should state the capacity being added, the date that capacity is needed, the operating cost the expansion is meant to change, and the consequence of not proceeding at all.

Success criteria follow from the business case and belong in the project management agreement, because they are what the project manager is being paid to protect. Vague criteria produce vague accountability. A criterion that reads on time and on budget is not a criterion. A criterion that reads occupancy permit issued before the autumn inventory build, with no more than five days of disruption to shipping, can be managed, tested, and reported against every period.

• Capacity target stated in operating units: pallet positions, production output, leasable area, dock doors, or clear height.
• The date the new capacity must be in service, and the business event that date is tied to.
• Maximum tolerable disruption to existing operations, stated in shifts, shipping days, or tenant-notice windows.
• The approved capital envelope, and the name of the person inside the organization who can authorize a change to it.
• Performance requirements the finished space must meet: floor loading, electrical capacity, temperature, clear height, sprinkler density.
• Handover requirements: occupancy approval, commissioning records, warranties, as-built drawings, and operator training.

Split the scope between the project manager, the design team, and the builder

Most disputes on an expansion trace back to a deliverable nobody owned. The project manager, the consultants, and the contractor each hold a defensible view of where their responsibility ends, and the gap between those views is where cost sits. Resolve it on paper before the first agreement is signed by listing the deliverables and assigning each one to a single party. The table below is a workable starting point for a commercial or industrial expansion.

The scoping sequence, in order

Scoping is a sequence, not a document. Each step produces a decision that constrains the next one, which is why owners who begin by asking a contractor for a price so often end up rescoping halfway through. Work through the following order and the project management agreement largely writes itself, because by the end of it you know precisely what you are asking someone to manage.

1. 01Write the business case: capacity added, in-service date, operating impact, and the consequence of not proceeding.
2. 02Test the site: zoning and permitted use, setbacks and lot coverage, servicing capacity, geotechnical conditions, and whether the existing structure can accept the addition.
3. 03Set the success criteria and the maximum tolerable disruption to operations, and have them signed by whoever controls the capital.
4. 04Establish an order-of-magnitude budget and schedule that includes approvals, then decide whether the project proceeds on that basis.
5. 05Choose the delivery model. Stipulated price, construction management, and design-build each change when the builder joins and what the project manager administers.
6. 06Define the project management scope deliverable by deliverable, using a responsibility matrix rather than a narrative description.
7. 07Procure the consultant team against a written brief, with deliverables, review cycles, and fee basis fixed before design starts.
8. 08Build the control budget in four layers and prepare the cash-flow forecast against the anticipated draw schedule.
9. 09Open the risk register and the decision log, and record who holds approval authority at each threshold.
10. 10Fix the reporting cadence, the fee structure, and the commissioning and turnover requirements in the agreement before work begins.

Consultant procurement and municipal approvals set the real schedule

On an expansion the consultant team is usually architect, structural, mechanical, electrical, and civil, with a geotechnical engineer, a building envelope consultant, and a code consultant added where the addition ties into existing assemblies or changes the occupancy classification. Procure them against a written brief. The standard Canadian consultant agreement forms give a defensible starting point, but the deliverable list, the number of design review cycles, and the fee treatment of owner-driven changes should be negotiated project by project rather than accepted as issued.

In British Columbia the approvals path commonly runs through a development permit where the site sits within a development permit area designated under the Local Government Act, followed by a building permit administered under the BC Building Code, with the BC Energy Step Code applying to the new work. Municipalities across Metro Vancouver and the Fraser Valley run their own review cycles and submission standards. An expansion that triggers a rezoning, a variance, or a servicing upgrade adds months rather than weeks, and Fraser Valley industrial sites can also sit on land inside the Agricultural Land Reserve, which is a separate question best answered before design money is committed.

In Ontario the equivalent gate is site plan control under the Planning Act, administered by the municipality, with building permits following under the Ontario Building Code. The Planning Act sets decision timelines for site plan approval, and municipalities across the Greater Toronto Area and Peel Region publish their own pre-consultation requirements and submission checklists. Confirm current timelines at pre-consultation rather than relying on a published service standard, because the statutory clock generally runs from a complete application and completeness is the municipality’s determination, not the applicant’s.

Build the budget in four layers

A budget that shows a single number is not a budget. An expansion budget needs four separate layers, each tracked and reported on its own line, because they behave differently, are consumed at different points in the project, and answer to different approvals. Collapsing them into one figure is how owners lose the ability to explain where the money went.

• Hard cost: the construction work itself, including site work, structure, envelope, mechanical and electrical, and the tie-in to the existing building.
• Soft cost: consultant fees, permits and development charges, surveys and testing, legal, insurance, project management, and financing cost during construction.
• Contingency: a design contingency drawn down as documents mature, plus a construction contingency held by the owner and released only against approved change.
• Escalation: an allowance for cost movement between the estimate date and the date the work is bought, which matters most on structural steel and long-lead equipment.

Industry practice on commercial and industrial work is to carry a larger contingency at concept and step it down at each estimate milestone as the design resolves. Two rules keep the structure honest. Contingency is held by the owner rather than by the contractor, and it is not a funding source for scope the owner decides to add. Scope additions are funded by a formal budget increase carrying the same approval as the original commitment. Blurring those two lines is the most common way a well-built budget quietly fails.

Cash-flow forecasting

Cash flow is a separate exercise from the budget and is routinely skipped. Construction spend follows an S-curve: slow through mobilization and foundations, steep through structure, envelope, and mechanical rough-in, then tapering through finishing and commissioning. Overlay the consultant fee draw, the permit and development charge payments that usually fall early and in a lump, and the statutory holdback that accumulates and is not released until the applicable period expires. An owner financing the expansion needs that forecast month by month, because a lender’s draw schedule and a contractor’s progress claim rarely align without active management.

Risk register, decision authority, and reporting cadence

Open the risk register during scoping, not after the first problem. Each entry needs a description, a named owner, a probability, a cost and schedule impact, a mitigation action, and a review date. On an expansion the predictable entries are known before design starts: unknown subsurface conditions, existing structure capacity, hazardous materials in the area being tied into, utility service capacity and connection lead times, municipal review duration, long-lead equipment, and the disruption profile for ongoing operations. Fire protection deserves its own line, because adding area or changing the stored commodity can force a sprinkler redesign in the existing building as well as the new one.

Decision authority is a scoping question that owners routinely leave until it becomes urgent. Record who can approve a change at each threshold, how long they have to respond, and what happens if they do not. A project manager with no delegated authority becomes a message relay, and the site stops while an email waits for a signature. A workable structure gives the project manager authority to approve minor changes within a defined limit against the contingency, requires owner sign-off above it, and escalates anything that touches the in-service date regardless of cost.

Reporting cadence should match the pace of decisions rather than a calendar habit. Monthly reporting is appropriate through design and approvals. Weekly reporting, supported by a short site meeting and a written record, is appropriate once construction starts. The report itself should be brief and should always carry the same items: committed cost, forecast to completion, contingency position, schedule against baseline, open risks with mitigation status, and the decisions the owner must make before the next report is issued.

Fee structure, contract form, and turnover

Project management fees are structured three ways, and the right one depends on how well the scope is defined. A percentage of construction cost is simple and scales with the project, but it rewards a larger project rather than a leaner one. A fixed fee against a defined scope and duration gives the owner cost certainty and is the strongest structure once the project is well defined, provided the agreement states what happens if the schedule extends. Hourly with a not-to-exceed cap suits early feasibility and scoping work where the extent of effort is genuinely unknown. Industry practice places commercial project management fees in the low single digits as a percentage of construction value.

The construction contract form belongs in the scoping conversation because it determines what the project manager administers. CCDC 2 is the standard stipulated price contract, the CCDC construction management forms cover services-only and services-plus-construction arrangements, and CCDC 14 covers design-build. Whichever form is used, payment administration follows the province. Ontario’s Construction Act sets prompt payment timelines running from a proper invoice, provides access to interim adjudication, and fixes holdback and lien preservation periods. British Columbia’s Builders Lien Act governs holdback and lien filing on its own schedule. Confirm the current requirements for your project with your own legal counsel before the contract is executed.

Scope commissioning and turnover at the beginning, because it is the part of an expansion most often left to improvisation and it decides whether the operating team receives a working facility or inherits a list of problems. Define what commissioning covers, who witnesses it, and what evidence is accepted. Define the turnover package: as-built drawings, operating and maintenance manuals, equipment warranties dated from acceptance rather than delivery, spare parts, training for the maintenance staff who will actually run the systems, and a deficiency list with completion dates. Tie holdback release to that documented package rather than to the day the last trade leaves the site.
