Task – Footing and flooring systems

1.Determine the location of the building in relation to other buildings and boundaries, and place the pegs in the ground marking the four corners of the building. You must make sure that the pegs are square by making the following check:

The distance between peg AA and peg BB is the same distance between peg CC and peg DD The distance between peg AA and peg CC is the same as the distance between peg BB and peg DD The distance between peg AA and peg DD is the same as the distance between peg BB and peg CC

2.Structural integrity – study the drawings showing details of the footings for this project. Describe how the footings – piers, pad footings (these are really pile caps), strip footings (this is really a pier and beam type system) and slab – contribute to the structural integrity of the building. You will need to address the following in your answer:
a. the purpose of each type of footing (the specific loads that are supported; why this type of footing is used; how the loads are transferred to the ground) (approx. 100 words each)

b. specific requirements for each type of footing (why they are the size specified; why they have reinforcement in the configuration shown; types of joints if applicable) (50 -100 words each)

1.) Spread (pad) footings：Spread footings are usually square or round, and support a

3.) piers ：Where footings are used on fill, unstable soils (subject to slip), low bearing capacity

3.Once the layout of the footings has been accurately set out on the site, construction of the footings can begin:
c. outline the construction method and sequence to construct each of these footing types (approx. 100 words each)

d. what codes and/or Australian Standards are relevant to the compliance requirements for these footings? (briefly outline what each covers)

 Pour concrete in the piers. The concrete is poured to approximately 500 mm below the NGL or FGL. No reinforcement is required in the pier holes. The concrete would be 20 MPa compressive strength.

After three days, excavate concrete beams between the piers. These concrete beams will
be excavated around the entire perimeter of the house.

NCC Vol 2, Part 3.2.5 Footing and Slab Construction
AS 2870–2011 Residential slabs and footings
AS 2159 & 3600 Concrete Pile Design
Construction method/sequence
Pile caps are constructed by excavating an area around the group of piles to enable form-work to be inserted. The pile tops may be trimmed to ensure they are at the same height. A reinforcement cage is then built and positioned in the formwork cast box and fastened to the piles.

Strip footings

 Excavate the pier holes. The number, location and spacing will be shown on the design engineer's drawings.

Submission

Preparation

Information such as People-in-charge, inspection method, requirement reference, frequency, acceptance criteria, stages, and Records or status of every single work should be included in all the elements of each part.

4.Read about the different types of joints in ground slabs.

Isolation joints are common to road pavements to allow thermal expansion, in buildings it is

commonly placed between a column and a slab in the ground floor and in a factory temperature is

The first floor office floors are essentially also slabs, a structural member in pr-construction it

is supported by form-works and strengthened by reinforcement bars. In post construction it is

 Removing of forms

Detail the sequence of activities for the construction of the office floors(approx. 100 words)

 COLUMN CASTINGS

 SLAB CASTINGS
