Tender & Contract Documentation

Tender Documentation


Ri & Ri Associates can provide both accurate and detailed tender documentation including Bills of Quantities for our clients, which essentially provides a reliable basis on which to tender for proposed construction works.

Bills of Quantities prepared by our practice have the following uses, and these are borne in mind by the Quantity Surveyor during their preparation:


Valuations for interim certificates

Valuation of variations

Ordering of materials if used with caution and awareness of possible errors and future variations

Cost analysis for use in future approximate estimating

Planning and progressing by the contractor's site planner

Final accounting

Quality by reference to the trade preamble clauses

Domestic subcontractor & suppliers quotations

Cost information

Provides a good basis for cost planning

The practice uses the latest computer Quantity Surveying and Estimating software for all Cost Planning and Bills of Quantities production, thereby providing an efficient and quality service to all our clients. The practice uses Buildsoft Quantity Surveying & Estimating Software which is highly regarded as excellent software in the construction industry, and is used by many Quantity Surveyors & Estimators worldwide. Quantity surveyors, large building contractors and development companies use this system for BoQ production, estimating, cost planning, variations and valuations.


The Bill of Quantities is designed primarily as a tendering document, but it also provides a valuable aid to the pricing of variations, and computation of valuations for interim certificates. Each contractor tendering for the project is able to price the work on exactly the same information with a minimum of effort. This therefore avoids duplication in quantifying the work, and allows for the fairest type of competition.


The Bill of Quantities normally comprises preliminaries, preambles or descriptions of materials and workmanship, and the measured works section. The preliminaries define the scope and nature of the work, contain details of the contract conditions, list of drawings and any special instructions to the contractor on pricing the job.

Contract Documentation


In relation to the contract documentation, after the Client has made a decision of an award of the contract, Ri & Ri Contracts Managers would then prepare and collate the necessary Contract Documentation and incorporate any agreed alterations that may have been made post-tender. Standard or bespoke Forms of Contract would be completed and we would arrange for the Contract to be signed by the Client and the successful contractor.
