ISO 10845-2:2020

Overview

ISO 10845-2:2020 - Construction procurement: Formatting and compilation of procurement documentation defines a uniform framework for preparing procurement documentation for supply, services and construction contracts at main and subcontract levels. The standard prescribes a format for calls for expressions of interest, tender documents, and contract documents, and sets out general principles for compiling procurement documents to improve clarity, transparency and digitization.

Key topics and technical requirements

• Structured component documents: separation of conditions of tender, conditions of contract, specifications, and measurement/payment documents so each subject is addressed once and in one place.
• Component list and content: guidance on notices and invitations, tender data, lists of returnable documents, returnable schedules, pricing data, scope of work and site information.
• Standardized format: recommended organization to make documents consistent, reduce ambiguity and enable easier navigation and electronic processing.
• Scope of work: expanded and revised requirements and guidance for describing deliverables, measurable outcomes and constraints.
• Procurement process information: guidance for calls for expressions of interest and tendering procedures to support selection, evaluation and acceptance.
• Annexed guidance: informative annexes include commentary on clauses (Annex A), examples (form of offer and acceptance, Annex B), a scope-of-work checklist (Annex C) and standardized procurement document examples (Annex D).
• Terminology alignment: aligns definitions with the ISO 10845 series and references ISO 6707-2 terminology where appropriate.

Practical applications

ISO 10845-2:2020 supports practical improvements in construction procurement by:

• Enabling consistent tender packages across projects to simplify bidder comparison and evaluation.
• Facilitating digital procurement and e-tendering through standardized document structure.
• Reducing disputes and pricing errors by clarifying allocation of risks, contract administration procedures and payment/measurement systems.
• Being adaptable for concession, design-build-operate and disposal contracts with minor adjustments.

Who should use this standard

• Employers / clients preparing tender and contract documents
• Procurement officers and contract administrators managing bids and awards
• Contractors, subcontractors and suppliers responding to tenders
• Quantity surveyors, project managers and legal teams involved in contract drafting and risk allocation
