Intermediate Floor Structure The spacing of joists and span of beam are checked. Timber trusses are bolted on steel beams. The gap between ceiling and steel beam is 10 mm, refer to drawings. Bracing is used

1. SITE PREPARATION AND FOORING

1.1

The relevant permissions are required including building permit and demolition permit before starts constructing.

1.2

Site clearing to achieve good site condition, old existing landscapes and buildings are demolished.

1.3

Site survey is done by the surveyor to identify the building blocks and helps determining the proper site boundaries.

1.4

Designing the pipes and plumbing system and other fixtures.

1.5

Site soil condition is tested and summaried in soil report.

1.6

Excavation of earthwork in trenches for foundation footings.

2. GROUND FlOOR SLAB

2.1

Depending on the soil condition, choose appropriate foundation type and contruct footings underground.

2.2

Laying underground pipework for sewage, gas and electricity.

2.3

Formwork and installation of the spacers. This is to maintain the concrete cover and garantee the durability of the building.

2.4

The reinforced steel is installed before the concreting the floor slab.

2.5

In concreting step, exposed aggregate concrete is poured and dried usually around 20 days.

3. VERTICAL STRUCTURE ABOVE GROUND

3.1

Steel type is selected and painted with corrosion resistant paint.

3.2

The steel framing system is constructed both in vertical and horizontal direction. Beams and trusser are bolted onto steel columns.

3.3

Exposed finishings are dealt with covering material.

3.4

Scaffolds are constructed on the ground for workers.

3.5

Ground floor timber stud framing is installed.

3.6

Structural bracing are installed to stud frames to support the structural systems.

Construction stages 1-4, summary

4. INTERMEDIATE FLOOR STURCTURE

4.1

After the installation of the vertical structural systems, intermediate floor structure construction starts.

4.2

Joists spacing and beam span are checked refer to construction drawings.

4.3

Scaffolding extends to the first floor to achieve the construction of first floor.

4.4

Floor substrate is installed by nails.

4.5

Timber trusses are bolted on steel beams. Joist hanger are fiexed on the timber trusses.
