CONSTRUCTION SEQUENCING GUIDE
Building design and construction is no small undertaking at any scale and every project comes with their own challenges having an
understanding of what might occur throughout the construction of your project can provide ease of mind and enable to you to be aware of
imminent issues before your project is delay. Effective project management through the construction stage mitigates construction cost risks and
ensures effective communication with consultants and the builder at every stage of project delivery.
TYPICAL CONSTRUCTION PROCESS
Each construction process is unique and will be influenced by different construction methods, builder and project manager preferences, project
scale, design requirement and site conditions. However a typical building sequence will be similar to the following:
Excavate site platform
Set-out the footings, excavate and pour
Form up and pour the floor slab
Set-out and construct house frame (timber, brick, block, steel)
Erect the roof framing/trusses
Fix roof cladding
Install external windows, plumbing and electrical (rough in)
Finish internal and external walls
Internal fit out, including services
Landscaping
NOTIFY CERTIFIER
Construction should always begin with the consultation of your certifier (this is done to ensure timeframes for the application process,
inspections are mutually understood to mitigate any issues that may hinder the progress of your project)
CLEAR SITE
Remove unwanted vegetation from the site
Level the site as per specifications (excavator may be required)
Erosion and sediment control devices installed
TEMPORARY POWER AND WATER
Prior to construction you will need temporary electricity, water supply and ablution facilities
SET OUT
Can be done by a surveyor, concretor, carpenter, bricklayer (accuracy is necessary to avoid expensive mistakes)
Accuracy with distances from boundaries to the building are crucial (these will be checked for compliance with building regulations by the
certifier)
EXCAVATION OF FOOTINGS
Site to be excavated for footings
Steel for the foundations is fixed into position
The engineer, certifier or both will inspect the footings prior to concrete being poured
FOOTING INSPECTION
Give notice (usually 24 to 48 hours) to the certifier
If used, the engineer, will also require notice
