Tender Documentation and Cost Support

Preparing a comparable basis for bids

A tender package should describe the work clearly enough for bidders to understand the intended scope, identify assumptions, and prepare their offers. Drawings, specifications, schedules, and commercial instructions must be coordinated with the client’s procurement approach.

Questions raised during bidding should be recorded and answered consistently so that participating contractors price the same clarified information.

• Tender drawings and specifications
• Scope and package coordination
• Cost-estimate inputs
• Bidder questions and clarifications
• Review support for submitted information

Cost awareness through design

Cost is influenced long before bids are received. Area, form, structure, systems, materials, site conditions, logistics, schedule, and market conditions all shape the likely construction requirement.

Estimates are most useful when their assumptions, exclusions, date, and level of design information are clear. As design develops, cost information can be reviewed against current decisions and client priorities.

Connecting procurement to the design record

Tender clarifications and accepted changes should be incorporated into the project record before construction proceeds. This creates a more reliable basis for contract administration and later site review.
