Taking off Procedure Flashcards
Define “Taking Off Procedure”.
The systematic process of measuring and recording the quantities of materials and works required for a construction project.
Why is a systematic approach essential in the taking-off process?
To ensure accurate documentation and coordination, and to manage revisions and quantities effectively.
What should be done upon receipt of drawings?
Drawings should be stamped with the date, recorded on a list including drawing number, title, date of preparation, date received, and number of copies.
What is the preliminary study of drawings?
Reviewing the drawings to understand the general character of the building and ensuring all necessary details are included and consistent.
Why is it important to compare drawings from architects and engineers?
To ensure there are no discrepancies in layout or dimensions.
What should be checked if overall dimensions are shown?
Check them against the total of room and wall measurements.
Why is an initial site visit advisable?
To get a feel of the job and visualise site references encountered in the drawings.
What happens if design details are not completed?
Measurement may start from a different point, and incomplete sections will be measured later.
What should be done if drawings have different scales?
Special care must be taken to use the correct scale when measuring from different drawings.
What is the importance of the specification in taking-off?
It provides detailed information on materials and work required, ensuring nothing is missed during measurement.
Why should materials be thoroughly understood by the taker-off?
To ensure accurate measurement and proper description of the work involved.
How should waste be measured?
Generally, work is measured to ascertain net quantities; wastage is allowed for by the contractor in prices.
What is the benefit of measuring overall with adjustments later?
It simplifies work and ensures consistency, reducing the risk of serious errors.
What are prime cost items and provisional sums?
Items included in the bill where exact details are not finalised, allowing for adjustments based on actual costs.
Why is it important to use consistent wording in descriptions?
To avoid confusion and ensure the same item is recognised across different parts of the bill.
