Class Activity 3: Ground floor framing and flooring
In this activity, the materials, labour and time requirements and labour rates of the various tasks
involved in constructing the ground floor framing and flooring of the proposed building are
determined.
Materials
It is important to note that the ground floor does not include the porch, garage and outdoor
living. The total ground floor area is 167.40m2. The ground floor framing comprises of the
following elements:
Joists
The joist system is comprised of parallel structural members running from one load-bearing wall
to another. The joists are made from 2 x 12 feet lumber and spaced 16 inches apart.

Take-Off and Calculations for Proposed Dwelling 9
The total ground floor area is 167.4m2 (which can be transformed into a rectangular shape of
18m by 9.3m) and the proposed spacing of the joists is 16 inches (0.4064m). Therefore the total
length of joists needed for the ground floor framing is:
18 m
0.4064 m =44.3+1=45.3 ≈ 46 pieces
The length per piece is 9.3m hence total length of joists is 46 x 9.3m = 427.8m
But the length of one piece is 12 feet = 3.6576m. Thus the total number of 2x12-foot lumber
needed is:
427.8 m
3.6578 m=116.96 ≈ 117 pieces
Subfloor
On top of the joists is the subfloor (strong structural layer) made of 4 x 12-foot, 0.75-inch-thick
plywood sheets screwed or nailed on the joists. The subfloor provides a stable surface for floor
coverings and heavy live loads in different spaces of the building. The subfloor also acts as an
additional bracing for controlling the joists’ lateral movement.
The total ground floor area is 167.4m2
The proposed plywood sheets to be used are 4 feet x12 feet = 48ft2 = 4.46m2
Total 4x12-foot plywood sheets needed for the subfloor = 167.4 m2
4.46 m2 =37.5 ≈ 38 pieces
Underlayment
Directly above the subfloor is the underlayment (a non-structural element), which smoothens the
subfloor thus providing a level surface on which the finished flooring surface will be placed. The

Take-Off and Calculations for Proposed Dwelling 10
underlayment material varies depending on the type of surface floor cover to be installed
(Wallender, 2019). Some of the underlayment materials used in this project include plywood (for
non-tiles) and troweled mortar (for tiles).
There are areas of the ground floor that are tiled while others are timber floored.
Titled floor area:
Ensuite= 7.35m2; laundry = 4.49m2; bath = 6.07m2; and WC = 1.88m2
Total = 19.79m2
Therefore mortar is needed to fix ceramic tiles to cover a floor area of 19.79m2
Timber floored (untiled) floor area:
Total ground floor area – total titled floor area = 167.4m2 – 19.79m2 = 147.61m2
The proposed underlayment material for this area is 4 x 8-foot, 0.5-inch-thick plywood sheets.
Total 4x8-foot plywood sheets needed for the untiled floor area = 147.61m2
2.97 m2 =49.7 ≈ 50 pieces
Floor covering
This is the topmost, visible surface of the floor. The floor coverings used in this project are
hardwood planks and tiles. Details of these are provided in floor finishes section.
The summary of prices of materials needed for the ground floor framing and flooring is provided
in Table 4 below.

Compliance with NCC and relevant Australian standards
The proposed building in this project is a detached house with a private garage. According to
NCC 2016 BCA Volume 2, the detached house falls under class 1a(i) – a single dwelling
(detached house) whereas the private garage falls under class 10a – a non-habitable building
(private garage) (Australian Building Codes Board, 2016). The design of the proposed building
has complied with all the necessary requirements of NCC 2016 BCA Volume 2. This includes
performance provisions, site preparation, masonry, timber framing, roof cladding, fire safety,
health & amenity, access & safe movement and energy efficiency. In general, the design of the
proposed building has met the performance requirements of NCC because it comprises both the
performance solution and deemed-to-satisfy solution.
The design of the proposed dwelling has also complied with the relevant BCA provisions and
Australian standards including AS 1170 (structural design actions), AS 1250 (steel structures
code), AS 1289 (methods of testing soils for engineering purposes), AS 1684 (residential timber-
framed construction), AS 1720 (timber structures), AS/NZS 1859 (reconstituted wood-based
panels), AS 2049 (roof tiles), AS 2050 (installation of roof tiles), AS/NZS 2269 (plywood –
structural specifications), AS 2870 (residential slabs and footings), AS 3600 (concrete

Take-Off and Calculations for Proposed Dwelling 14
structures), AS/NZS 4505 (garage doors and other larger access doors) and AS 4773 (masonry
for small buildings). The three activities covered in this task (ground floor framing and flooring,
finishes and roof framing & roof trusses) have complied with NCC and relevant Australian
standards mentioned above.
