Compare Connections, City Requirements and Total Scope

Provide the symptom timeline, existing-system dossier, route sketch, inspection footage, access measurements, tree and hardscape notes, known outlet records and relevant City correspondence. Use a common list of questions and require bidders to state which evidence supports the proposed boundary. If one contractor includes investigation that another assumes is complete, separate that cost before comparing totals. A consistent package reduces the risk that quotes reflect different facts, different foundation sides or different definitions of perimeter drain replacement.

Issue one dated property file

Require evidence-linked boundaries

Separate investigation from construction

Create a row for the proposed outlet, the document or observation supporting it, and the person responsible for confirming requirements. Victoria states that installing or altering a stormwater utility connection requires a plumbing permit and directs connection questions to Engineering, while site-drainage work can involve different circumstances. Do not turn that general page into a property-specific permit decision. Record the address, described work, dated City response, application or inspection owner, fees or deposits if confirmed, and any unresolved prerequisite.

Name the proposed outlet

Assign City confirmation

Retain dated responses and conditions

Compare included foundation sides or lengths, assumed depths, access method, utility locating, tree measures, spoil handling, temporary water control and protection of neighbouring surfaces. Ask for quantities, unit rates or clearly defined allowances where practical. Keep excavation safety with the responsible contractor and qualified reviewers. A lump sum with no mapped boundary cannot be fairly compared with a proposal that identifies each side, obstacle and restoration area. Mark conditions that could change the excavation method or price after exposure.

Map the excavation boundary

Compare quantities and allowances

Identify hidden-condition triggers

Place wall preparation, crack or penetration review, membrane or drainage layer, protection, pipe, fittings, cleanouts, sumps, pumps, aggregate, separation material and transitions in one table. Confirm that every item is actually included and supported by current product information where applicable. Keep structural work and professional design separate unless expressly reviewed and priced. Compare installation details and pre-cover hold points, not only product names. State who produces the photographs, measurements, inspection records and final route diagram.

List components line by line

Separate structural and drainage scope

Require pre-cover evidence

Compare soil, lawn, plantings, protected trees, irrigation, fences, decks, stairs, concrete, asphalt and pavers by area and finish. Identify what is restored, allowed for, excluded or assigned to another trade. Review settlement, plant survival and material-matching limitations. List other exclusions such as electrical supply, pump backup, hazardous material, structural repair or neighbour access only when relevant to the offered work. A lower drainage price can create a higher total property cost when access and surface restoration sit outside the contract.

Price restoration by surface

Separate allowances and exclusions

Compare total property cost

Require written authorization before added work, with photographs or measurements showing the condition that triggered it. Compare mobilization assumptions, weather contingencies, daily protection, inspection timing, payment milestones and responsibility for delays tied to approvals or hidden conditions. Then list closeout deliverables: permits or inspections, product documents, testing, route and component photographs, final drawings, maintenance information and remaining exclusions. Avoid unsupported warranties or dry-basement guarantees; compare only written terms that can be verified in the actual proposal.

Require written changes

Tie payments to evidence milestones

List closeout deliverables

Score proposals for evidence, defined boundaries, access planning, wall and drain components, outlet confirmation, City responsibility, testing, restoration, schedule, closeout and change control. Verify qualifications, insurance and contract terms through appropriate records rather than website claims. Resolve material differences in writing before selection. The wet-basement, older-system, inspection, tight-access and replacement pages supply the supporting checklists. Retain the comparison and all clarifications with the accepted agreement so changes can be measured against the scope that was actually approved.

Resolve differences before award

Compare total responsibility, not one number

Keep the matrix with closeout records
