Canada infrastructure tenders often ask suppliers to deliver work while roads, buildings or essential services remain partly in use. The headline duration of an access window can hide several non-productive activities: setting up protection, obtaining permission to start, moving equipment and returning the area safely. A credible offer makes those activities visible in both the programme and the price instead of assuming that every available hour produces completed work.
A recent bridge notice illustrates the planning issue
On 11 September 2026, Public Services and Procurement Canada announced motorist closures of the Alexandra Bridge for inspection work on 14, 15 and 18 September, from 9:30 am to 2:30 pm. The notice kept the boardwalk accessible to pedestrians and cyclists and warned that weather could change the schedule. These dates have passed. This is a retrospective planning example, not a current tender or a claim that the work is available. Source: PSPC, 11 September 2026.
Translate access conditions into a delivery sequence
Begin with the actual tender documents for your opportunity. Identify who grants access, who controls public movement and what must be completed before an area can reopen. Check whether equipment can remain on site between shifts. A method that depends on overnight storage is not credible if the site must be fully cleared every day.
Draw a sequence for one representative shift. Show arrival, setup, authorisation, productive activity, checking and handback. The purpose is not to invent a detailed construction method before the scope is known. It is to test whether the promised output fits the available period and whether the estimate includes the resources required to make that period usable.
Give unresolved conditions a named owner. An access assumption should not disappear between the estimator and the person writing the technical response. If a clarification changes the permitted hours, revisit quantities, crew arrangements and price rather than altering the programme alone.
Connect each constraint to a priced activity
| Constraint to examine | Programme consequence | Pricing question |
|---|---|---|
| Daily setup and removal | Less time for the core task | Are repeated mobilisation costs included |
| Shared public access | Separate routes or staged work | Who provides and maintains the separation |
| Weather dependent activity | Possible rescheduling | What standby or remobilisation basis applies |
| Formal handback | Checking before the deadline | Are inspection and restoration resources allowed for |
Use the buyer's prescribed pricing format. An internal breakdown can be more detailed than the submitted schedule, but the totals must reconcile. Avoid disguising an uncertain cost inside an unrelated line simply because the returnable form has no obvious place for it. Ask a permitted clarification or obtain commercial review.
A fictional example of productive time
A fictional inspection contractor is considering a Canadian municipal opportunity with an assumed six-hour daily access period. Its planner initially allocates six productive hours. A joint review with the site supervisor identifies ninety minutes for setup, checks and handback, leaving four and a half hours for the inspection itself.
The estimator then recalculates the number of shifts and tests the proposed staffing arrangement. These figures are illustrative and are not taken from the Alexandra Bridge work. The lesson is to expose the assumptions early enough to make a reasoned bid decision, not to apply the same allowance to every site.
Review the offer as a single commitment
Read the technical method alongside the price schedule. If the method promises separate crews, extended supervision or continuous public access, identify where that commitment is resourced. Check whether subcontractor quotations use the same hours, quantities and access assumptions. Record material exclusions and confirm how the tender permits them to be handled.

Frequently asked questions
Is the Alexandra Bridge notice an open opportunity
No. It is a public traffic advisory for September dates that have already passed. Find the current notice and documents for any opportunity you intend to pursue.
Should every possible delay be added to the price
Assess the actual allocation of risk and the buyer's instructions. A blanket allowance can be as misleading as ignoring a material dependency. Seek appropriate commercial advice.
Who should approve the access assumptions
The estimator and operational lead should review them together, with specialist input where required. Both the written method and the cost model need to reflect the approved basis.
