Unit rates and rate analysis

A unit rate analysis is the only written proof of why a piece of work costs what it costs. Whether in an abnormally low tender explanation or a new rate determination, the question is the same: which published rate, from which period, does this figure come from?

Analyses are taken on their own: one item, one new rate or one list. If the whole response to an employer's query is needed, the file runs from Abnormally low tender explanation — the analyses there are the same analyses.

Scope

• Public and composite items — building unit rate analyses on institutional rates.
• Special items — analyses supported by supplier pro-forma invoices.
• New rates — analyses at current market prices for work outside the contract.
• Input tracking — material, labour and plant inputs recorded with their period.

Where we have done it

Trabzon–Artvin–Ovit Tunnels electromechanical and SCADA systems (TRY 437.5 million, 2024), Bingöl–Genç 9th Region Border Road (TRY 115.35 million), Malazgirt–Patnos State Road (TRY 42.05 million) and Karbala Refinery.

What is different

Input prices come from records, not memory: every material, labour and plant line is stored with the institution and month of the rate it was taken from. Even in a file opened years later, the basis of the analysis can be rebuilt.
