A build-to-suit transaction may use an offer, agreement to lease, development agreement, work letter, construction schedules, drawings and a long-form lease. The labels and sequence vary. What matters is that the documents form one controlled record of who must deliver what, by when, at whose cost, to what standard and with what consequence if delivery changes or fails.
This is general information, not legal, tax, environmental, engineering, accounting or investment advice. Obtain advice specific to the property and transaction.
1. Build a single document hierarchy
Index every agreement, schedule, drawing, specification, report, budget and amendment. State priority when documents conflict and identify which provisions survive completion or lease commencement.
Do not let proposal language silently override technical schedules or vice versa. Counsel should control interpretation and execution.
- Site control
- Conditions
- Scope
- Budget
- Milestones
- Changes
- Acceptance
2. Define site and approval conditions
Record title, control, diligence access, zoning, development, subdivision, servicing, environmental, financing and other conditions with responsible party, evidence, deadline, waiver authority and failure consequence.
Municipal approval cannot be guaranteed by the owner, tenant, broker or design team. State which approvals are conditions and which risks remain after waiver.
3. Freeze the design basis deliberately
Attach the approved program, site plan, floorplans, elevations, specifications, equipment loads, performance criteria and area method. Use a signed design-freeze record before pricing or construction milestones rely on it.
Define who approves design development and what silence means. Avoid deeming an incomplete or unreviewed package accepted merely because a calendar date passed without a controlled submission.
4. Separate base scope, allowances and tenant work
Create responsibility matrices for land, base building, site, services, fit-up, equipment, furniture, technology, signage, consultants, permits, commissioning and move. State taxes, markups, contingencies and unused-allowance treatment.
An allowance is a financial limit, not a complete specification. Document eligibility, approval, payment evidence and whether overruns change rent, require cash or reduce scope.
5. Control pricing and change orders
Define estimate stages, open-book evidence if applicable, tendering, owner contingency, tenant contingency and reconciliation. Every change should identify scope, cost, rent effect, tax, schedule, approvals and authorized signatories.
Do not approve a schedule-only or cost-only change when the same decision affects both. Preserve rejected and superseded versions to explain the final result.
6. Define milestones and delay consequences
Schedule design, submissions, permit release, procurement, construction, utilities, inspections, commissioning, substantial completion, fixturing, occupancy and rent commencement. Identify notice and update requirements.
Separate delay caused by the developer, tenant, authority, utility, hidden condition or force majeure. Counsel should draft extensions, outside dates, termination, cost allocation and any liquidated or other remedies.
7. Make completion evidence objective
Define substantial completion, legal occupancy, development completion, commissioning, testing, area certification, deficiency thresholds and required professional or municipal evidence. A usable building and a technically complete contract milestone may not be identical.
Calgary and Edmonton publish distinct municipal process information. The project team must confirm current location-specific requirements rather than reuse another municipality's checklist.
8. Reconcile commencement and long-term operation
Connect access, fixturing, possession, occupancy, opening, lease commencement and each rent stream to objective dates and notices. State utilities, insurance, security, maintenance and risk transfer during every transition period.
Deliver the executed lease, amendments, approved drawings, as-builts, permits, warranties, manuals, commissioning and deficiency record to operations. This guide is educational and is not a form agreement or legal, design, engineering, construction, tax, accounting or financing advice.
