Compare hydroseeding bids on the same scope

Two hydroseeding quotations can show different totals because they describe different projects. One may include preparation and establishment visits; another may cover application only over an assumed area. A unit price becomes useful only after those differences are visible. This HAUSE workbook helps an owner compare the actual scope before selecting a proposal. It does not provide market rates, promise savings or establish legal contract terms. The goal is a clear comparison of inclusions, assumptions and unresolved decisions that each bidder can confirm.

Issue one common project brief

Give each bidder the same current drawing, intended use, measured treatment area, photographs and known constraints. Identify shade, slopes, difficult access, water availability and construction phases. State which information is confirmed and which remains an allowance or assumption. If one bidder visits the site and discovers a material difference, update the common brief so competing proposals do not rely on different facts.

Record any required specifications by exact edition and project applicability. The City of Calgary — current landscape specification editions index distinguishes current and superseded landscape editions, illustrating why “to city standard” is incomplete without an identified document and scope. Do not assume a municipal park specification automatically applies to a private yard. Ask the designer or responsible project representative to confirm what actually governs the work.

Separate the major cost-bearing operations

Create rows for investigation, clearing, soil work, grading interfaces, final seedbed preparation, application, water provision, establishment maintenance and inspections. Ask each bidder whether the row is included, excluded, provisional or performed by another party. FINN — preparing ground for grass seed treats preparation as a distinct part of establishment. That supports checking whether a quote includes it; it does not justify assuming the cheapest application-only bid includes all necessary ground work.

Include mobilization and phasing. A project released in three visits may differ from one continuous operation. Identify who bears the cost when another trade delays access or damages prepared ground. Do not silently add an estimated value to an exclusion and present the adjusted number as the bidder's offer. Request a priced clarification or keep the unresolved item visible until it can be compared honestly.

Compare identifiable materials and documentation

Ask for the intended seed mixture and product descriptions, with the level of detail appropriate to the project. “Premium seed” and “heavy mulch” are not comparable technical descriptions. Identify whether material rates and quantities are specified, proposed for review or left undefined. Keep any alternative product option separate from the base scope so a substitution does not disappear inside the total.

CFIA — seed testing, grading and labelling is the Canadian reference for seed testing, grading and labelling. Request appropriate seed identification and supporting information rather than treating a supplier's generic brochure as proof of the delivered lot. Do not demand irrelevant documents simply to make the tender look more sophisticated. Each requested record should support a selection, conformity or traceability decision.

Use a comparison matrix before comparing totals

The entries are illustrative, not real bids. They show why dividing both totals by the same assumed area can create false precision. Until the 100 m² area difference is resolved, even the denominator is uncertain. A lower quoted total may reflect less work, a different material plan or an unassigned maintenance obligation.

Evaluate care and acceptance as part of the purchase

Ask who provides water, changes settings, checks coverage and records concerns. Identify whether the proposal includes active establishment service or only an installation and handover. Neither arrangement should be misrepresented. The owner must know what time, equipment and competence remain their responsibility. Include first-mowing and access decisions in the discussion because they affect how the property can be used after application.

Review the proposed acceptance basis and any repair process before signing. Application completion, visible emergence and a durable lawn are different milestones. Ask how concerns will be documented, who reviews them and which conditions require a scope change. Avoid accepting a guaranteed finish date without understanding its assumptions, and avoid inventing a warranty where the proposal does not state one. Obtain appropriate contract advice where terms are material or unclear.

Keep the final clarification trail

Give every clarification a date and connect it to the final proposal revision. Before selection, check that accepted exclusions, alternatives and responsibilities appear in the actual contract documents rather than only in an email remembered by one person. Preserve the common brief and the chosen material schedule. When the project changes, that baseline makes it easier to identify what changed and why.

Give unresolved items their own decision column instead of assigning them a score that suggests certainty. For example, an unknown water connection should trigger a site check and a revised scope, not a guessed financial allowance that makes one bid appear comparable. Record the date by which each clarification is needed and whether it could change the selected material, schedule or maintenance arrangement. This keeps selection tied to a deliverable project.

Cost factors include access, area geometry, preparation condition, selected materials, water logistics, phasing and maintenance. Their effect is project-specific; this workbook intentionally supplies no invented local rates. Continue with scope boundaries, quantity reconciliation and maintenance budgeting.
