4.0 Before wall construction begins

You need to perform the following checks before construction begins to ensure wall frames are erected correctly.

4.1 Check that frame dimensions are compatible with the slab or subfloor 

You need to check that the layout generated from ENDUROCADD^® matches the building layout and that all setout dimensions and identification marks have been provided.

Measure your slab or floor platform to ensure the frame will sit within its dimensions. This will highlight any discrepancies between the two that must be catered for during setout.

4.1.1 Concrete specifications

You must ensure that the concrete slabs, exposed footings, and columns and walls are correct as per the following specifications.

4.1.1.1 Slabs

• Maximum deviation from any specified height, plan or cross-sectional dimension to be the greater of ¹/₂₀₀ times the specified dimension or 5mm in accordance with AS3600 - 2009: Concrete structures.

• Surface level to be within +/-5mm of specified level

• Exposed edges to be Class 3 in accordance with AS 3610.1: Formwork for concrete and surface finish.

• Flatness - Maximum deviation from a 3m straight edge placed anywhere on the surface: 5mm.

4.1.1.2 Footings - Exposed

• "As for 'concealed' above plus - Maximum deviation from plumb to be the greater of ¹/₂₀₀ times the specified dimension or 5mm in accordance with AS3600 - 2009: Concrete structures.

• Maximum deviation of any point on the surface from a straight line joining any two points on the surface to be the greater of ¹/₂₅₀ times the length of the line or 10mm in accordance with AS3600 - 2009: Concrete structures.

4.1.1.3 Concrete Columns & Walls

• Within +/-15mm of specified position and +/-5mm of plumb.

4.2 Check that frame setout is correct as per the architectural plans

You must complete setout using the architectural plans to ensure all relevant measurements are transferred to the slab or sub-floor.

4.3 Check that frames are installed the right way up and face the right direction

You must ensure that frames are installed the right way up and face the right direction.

4.4 Check any site modifications with the design engineer

Minor modifications to wall frames are easily made on-site if required. However, you must check with the design engineer for any structural implications.

4.5 Check compliance with statutory regulations

You must ensure that all statutory regulations are complied with during the construction process.

4.6 Check correct direction of ENDUROWALL® profile

The direction of the channel section used for the frame should be as depicted on Frame Assembly diagrams in Figure 6.2.

4.7 Check that frames are installed straight and square

Frames must be fixed plumb and straight during wall erection. Frames have not been installed correctly if there is a bow or tilt evident after fixing. You must rectify the problem before proceeding.

4.7.1 Straightness

Check the straightness of the wall frame using a long spirit level. Straight walls must not deviate by more than 5mm over a 3m length as shown below. Where wall panels join to form a continuous wall, the critical face or faces of the panel must not deviate by more than +/- 2mm at the joint.

4.7.2 Square the frames

Check the squareness of wall frames by either:

• taking diagonal measurements for equal dimensions

• performing a 3,4,5 (Pythagoras' Theorem) check

• clamping into a square jig.

Open

4.7.3 Plumb

Out of plumb at any point along the length of the wall frame from top to bottom, must not exceed the maximum of ^h/₆₀₀ or 3mm unless the frames are specifically designed to be installed out of plumb. Columns & Walls must be within +/-15mm of specified position and +/-5mm of plumb.
