By referencing this standard, architects and engineers can avoid the pitfalls of vague descriptions. Instead of reinventing the wheel for every project, they can cite specific clauses from the 2020 edition, ensuring that all stakeholders—from quantity surveyors to site supervisors—share a unified understanding of the technical requirements. This standardization streamlines the procurement process, allowing for "apples-to-apples" comparisons during tendering, as contractors bid based on identical quality parameters.
