PROJECT QUOTATION

Procurement & delivery

Project quotation and enquiry guide

Agree scope, materials and delivery conditions before comparing prices; a clear enquiry reduces repeated clarification.

PROJECT OVERVIEW

Understand the conditions before choosing a solution

Project quotations depend on design and site conditions. Similar areas of carports, landscape roofs, stands and tank covers can require different forms and works. This page helps organise enquiries, compare offers and manage changes; the pricing article explains individual cost components.

Use consistent measurements

State whether the price uses plan projection, developed membrane area or another basis.

List included works

Identify foundations, drainage, transport, lifting and taxes individually to reveal omissions.

Retain design revisions

Link each quote to its drawings and materials schedule, confirming cost and programme effects of changes.

Key considerations

Start with concise requirements

Without complete drawings, provide location, use, length, width, height and photographs, with budget range and desired delivery date.

Initial estimates guide decisions. Prices become more precise once dimensions, foundations and materials needing further work are confirmed.

  • Essential functions
  • Alternative appearance and material options
  • Works already completed by others
Key considerations

Use one scope schedule for all suppliers

Ask for separate design, materials, fabrication, foundations, transport and installation items, listing unknown conditions separately.

Check whether removal, reinstatement, night work or remote mobilisation actually apply. Unnecessary works need not be assumed, but conditions should be explicit.

Key considerations

Agree changes and handover before ordering

Column, material, colour and drainage changes can affect fabrication and site work. Record the approving person and drawing revision.

Compare payment stages, validity, delivery and acceptance as well as price. Distinguish material warranties, workmanship warranties and design life.

SCOPE & COORDINATION

Define each part of the work

Use the same scope for proposals, quotations and handover.

PROJECT JOURNEY

From requirements to an agreed scope

  1. Submit requirements

    Collect site, use, dimensions and expected scope.

  2. Review assumptions

    Confirm outstanding measurements, selections and external coordination.

  3. Obtain itemised quotations

    Compare cost and documents against equivalent scopes.

  4. Approve the final revision

    Align drawings, materials, changes and acceptance requirements.

START YOUR PROJECT

Prepare these details for your enquiry

Share the location and current requirement so we can review conditions and scope together.

  • Location and principal use
  • Photographs and available dimensions
  • Reference proposal or existing drawings
  • Foundations, removal and supporting scope
  • Budget range and desired delivery milestones

QUESTIONS & ANSWERS

Frequently asked questions

Why do square-metre prices differ so much?

First check measurement, structure, materials and installation boundaries. Identically named unit prices can represent different work.

Can we discuss budget before drawings exist?

Yes, with clearly stated assumptions and unresolved conditions. An estimate is not the final contract price.

Is the lowest quote the best value?

Compare complete costs after establishing equivalent requirements and documents, then review delivery, changes and maintenance conditions.

Is the original quote valid after design changes?

Have the supplier identify unchanged and revised items and issue a new version reflecting the effects.
