Step 1 – Marking out the Perimeter of the Carport
Mark and set-out the perimeter of the Carport with pegs and strings. In this example, the size of the
carport is 6.0m wide x 6.0m long. Refer to Engineering Plans for the actual size and specifications of
your specific job.
Step 2a – Footing Set-Out for Concrete Block Pad Footing
Mark and set-out the location of concrete pad footings to be excavated. The centre line of the posts
is equivalent to the centre line of the pad footings. Using the string set-out of the perimeter as a
guide, edge of the post is set in on the sidewall by the flange width of the Rafter. To determine the
centreline of the post, add 1/2 of the post size to the flange width of the Rafter.
Example: C150 Rafter has a 64mm flange width so the edge of the post is set in by 64mm from the
string set-out. The post size is 75mm x 75mm so half of 75mm is 37.5mm. The centreline of the post
is 64mm + 37.5 set in from the string set-out.
The posts are set in on the endwall by 1300mm to centre line of posts as shown in Diagram Ab.
Ensure that the diagonal measurements of the pad footings are equal, level and square. Refer to the
Engineering Plans for size and specifications of the concrete pad footing. Dig out and pour concrete
pad footings.
