Is this a fixed price contract?
There is potential for the contract price to vary when the site is not level, there is not clear access for a 6 Mt concrete truck to reach the side of the slab area, and when there is no power and generators are required. Concrete floors costs are based on city supply costs and therefore may vary in country areas. In those areas a site inspection will be carried out and local supply costs determined, after which the concrete floor costs are fixed.
Do I need a building permit?
Any structure greater than 10Mt2 requires a building permit.
How do I calculate the cost of works?
It is the responsibility of the building surveyor to check that the cost of works includes the cost of the preparation of drawings, permit costs, site preparation, all materials, installation labour, concrete floors, and connections to the legal point of discharge.
What is a “Legal Position”?
A steel garage can be 0.15 or 1.0 Mt off the boundary but nothing in between (e.g. not 0.60). The building must also be 1.0 Mt away from the house or any building attached to the house. Other checks must also be made considering the easements and overshadowing rules.
Can I build over an easement?
A steel building can be built over an easement with the consent of the proper authorities. To build over a drainage and sewerage easement, permits approvals are required from the local sewer authority and the local council. A building permit cannot be issued until these permits are supplied to the registered building surveyor. In general a steel building is not allowed to cover more than 6.5 Mt of the pipes in the easement.
What approvals does an owner-builder need?
When an owner builder is nominated, a Certificate of Consent from the Building Practitioners Board is required to be issued when the domestic building work is greater than $12,000. An owner-builder will not be able to obtain a building permit without a Certificate of Consent.
What obligations do owner-builders have when selling?
If a property owner sells their house within six years of completing work as an owner-builder, they must provide warranty insurance cover to the purchaser of the property. They are also required to provide a technical inspection report that identifies defects. It is an offence to sell a building without the required report and insurance. Penalties of up to $10,000 apply.
Can owner-builders undertake demolition and removal work?
It is rare for a permit to demolish a building to be issued to an owner-builder. To obtain such a permit, the owner must demonstrate to the relevant building surveyor that he or she has the necessary knowledge, experience, equipment, and storage facilities to properly conduct the demolition operations as required by the Building Regulations.
Should I lay a concrete floor first or last?
Concrete is very corrosive. If a concrete floor is poured after competition of the building, there will be corrosion of the cladding around the bottom 300mm or so of the wall sheets. Bluescope Lysaght will also void their Colorbond warranty if any part of the wall cladding is stuck to concrete.
Our recommendation is that all steel buildings have the slab laid first. By laying the concrete floor first, the concreter is able to properly box the concrete and finish it to a professional standard. All our slabs are laid completely level. It is also easier for the concreter to deal with site fall and other customer requirements. The side wall cladding overlaps the concrete floor by 40mm and therefore will be waterproof. If required, “vermin flashings” are available to prevent dust and vermin coming into the building.
What warranty is there on the building?
All buildings have a 6.5 year structural warranty. Different components have varying warranty eg windows, rolladoors which we pass on as per the manufacturer’s warranty. Any installation works are backed by a 12 workmanship guarantee.
