Level Dimension Tolerance

The level & tolerance policy relates to the delivery of construction works how they are supposed to be to deliver the works to the quality required – the size, shape, surface finish, location and allowable variance from these documented requirem...

1.1 Supervision of concrete pours is essential to achieving the level tolerances required. 1.2 Concrete placement and finish is easily the most significant trade to regularly FAIL to provide the required finishes and are typically the first to...

Pre-Pour 2.1 Check the weather forecast to assist in the planning of the date/time for pouring. 2.2 The concrete foreman should have a plan of the slab with the required levels and finishes marked up clearly on the drawings. He should be a...

3.1 Formwork is determined by the code of practice (workplace health and safety) for design of the formwork support systems and the Australian standard 3610 which dictates the quality standards including surface finish and tolerance. 3.2 Commo...

4.1 The main issues with block work are: 4.1.1 Penetration sizes that are slightly different to block coursing sizes – makes it difficult to trim a block down 20mm to suit a size set by a mechanical contractor unnecessarily. When a penetration...

There are 3 main stages in the completion of structural steel where the tolerances of the work are affected; 5.1 Review of shop drawings 5.1.1 A lack of thorough review of the shop drawings against the (sometime) poorly co-ordinated architec...

6.1 It should be noted that in respect to surface finish tolerance, where there is no applied finishes – the concrete finish need to achieve the requirements of AS1428.1

7.1 If we can guarantee opening sizes up front significant time savings can be achieved by reducing the need to site measure. Frames can be fabricated in standard sizes which is a significant cost saving in the manufacture and fabrication of windo...
