Knowing how to read and interpret them are essential for planning and undertaking projects successfully. They are also an important means of communication between all parties involved in a building project – they help to ensure everyone has the same understanding of what the finished project is intended to be and how to achieve it. Plans, working drawing, and specifications are also needed to: → show compliance with the functional and performance requirements of the Building Code so that a building consent can be obtained under the terms of the Building Act → allow the work to be accurately priced/estimated → allow the work to be correctly constructed as envisaged by the designer → form part of the contractual agreement between the owner and the builder. You can apply the learning you do for this unit standard when when/if you get the opportunity to Demonstrate knowledge of and create sketches and drawings for BCATS projects (US 24353, 6 credits) and when you need to use project documentation to create cutting lists, complete order forms, and construct your BCATS projects. 4 22607 Plans & specifications How you will be assessed You need to show your teacher/tutor that you can: → identify plans, working drawings and specifications and describe what they are used for → identify and interpret abbreviations and symbols on plans, working drawings and specifications → identify any preliminary work from plans, working drawings and specifications → use plans, working drawings and specifications to determine the quality and types of materials required. Your teacher/tutor will give you a set of plans and specifications to read. You will need to use these to complete a Knowledge Assessment, which your teacher/tutor will mark.

FAQs

What is the main purpose of plans, working drawings, and specifications in BCATS projects?

They provide clear information for a proposed building project so all parties understand what is required, how it will meet requirements, and how it will be constructed. They also support communication and contractual agreement between owner and builder.

What do learners need to demonstrate to pass the assessment?

Learners must identify plans, working drawings, and specifications, interpret symbols and abbreviations, identify preliminary work from the documents, and use the documents to determine required material quality and types.

What does “drawing to scale” mean in working drawings?

Because full-size drawings are usually impossible, the building project or location is reduced proportionally to fit the drawing paper. This scaling process should be clearly recorded on the drawing.
