Projavio is in private beta | applications now open for UK construction consultancies.

Module · Estimates

Two estimating modes. One source of truth.

Benchmark estimates for early-stage feasibility (sector × tier × GIA → cost). Detailed estimates with NRM2-structured BoQ, draft → submit → approve workflow. Both share rate libraries and feed the PCSR.

Why estimating breaks

Most consultancies estimate twice - and find out the answer differs.

Early-stage feasibility lives in one workbook with sector benchmarks. Detailed pricing lives in a different workbook with line items. They drift. The early estimate the client agreed to and the detailed estimate the team builds out diverge by 20%.

Two estimating tools, two answers

Feasibility £/m² in one tool, line-by-line BoQ in another. By the time the detailed estimate lands, the budget has shifted - and the client conversation gets uncomfortable.

Rate libraries that age silently

The benchmarking rate sheet was last updated in 2022. The latest QSR is being priced off three-year-old rates. Nobody noticed until the variation comes in.

No approval gate on detailed estimates

A junior team member emails the client a detailed estimate that hasn't been signed off. Three weeks later, the partner has to walk it back.

What's inside

Two modes, one stack.

Benchmark estimates

GIA × sector × tier (Bronze / Silver / Gold) → cost. Live rate library per sector. For early-stage feasibility and option appraisal.

Detailed estimates

NRM2-structured BoQ, line-by-line, with rate-item lookup. Categories roll up to packages; packages roll up to total.

Draft → submit → approve

Detailed estimates flow Draft → Awaiting Approval → Approved. Cost Coordinator drafts; Cost Manager approves. Notifications wire to the right reviewer.

Sector-aware rate libraries

Rates keyed to sector + tier. Rename a sector, the rates follow (FK-linked under the hood - see the sector linkage architecture).

Cost report integration

Approved detailed estimates feed the project cost report as the original budget basis. The PCSR you ship next month builds on the estimate signed today.

Estimate-to-procurement flow

Approved estimate packages can be sent through to procurement as tender pack starting points - no re-keying of the BoQ.

Who uses it

Built for the people pricing the work and the people checking the numbers.

Cost Coordinators

Draft a detailed estimate in the proper structure; submit for approval; the Cost Manager reviews it; client conversation follows.

Cost Managers

Review and approve estimates with full audit. Client never receives an unsigned estimate; partner is in the loop.

Quantity Surveyors

Benchmark for feasibility, detailed for pricing. Two views, one rate library, no drift.

Frequently asked questions

Does Projavio cover both feasibility and detailed estimates?

Yes - Benchmark Estimates handle early-stage feasibility (sector × tier × GIA), Detailed Estimates handle line-by-line BoQ pricing. Both share rate libraries and both feed downstream modules.

Are rates standardised or workspace-managed?

Workspace-managed. Each consultancy maintains its own benchmark and detailed rate libraries against its own sector taxonomy.

Can detailed estimates be locked once approved?

Yes - Approved estimates lock line items and stamp the approver. Re-opening for revision creates a new draft estimate; the prior remains the historical basis.

Do you support NRM2?

Detailed estimates structure to NRM2 categories (Substructure, Superstructure, Internal Finishes, etc.) so the package roll-up matches the standard your clients expect.

Stop estimating twice.

One rate library. Two estimating modes. The PCSR builds itself off the same numbers.
