Building (General) (Cost of Building Work) Determination 2011 (No 1)
Notifiable Instrument NI 2011— 251
made under the
Building (General) Regulation 2008, Section 11 (1) (a)

1.	Name of instrument
This is the Building (General) (Cost of Building Work) Determination 2011 (No 1). 
2.	Commencement
This instrument commences on 1 July 2011.
3.	Instrument Revoked
I revoke instrument NI 2010-275. 
4.	Determination
I determine that, subject to the other sections of this instrument, the method that must be used under Building (General) Regulation 2008, section 11 (1) (a), to calculate the estimated cost of building work, which is required to be contained in an application for building approval under the Building Act 2004 is as follows—
(a)	for the building work described by combining columns 1 to 3 of the schedule, apply the relevant rate prescribed in column 4 of the schedule to give the estimated cost of the work in dollars; and
(b)	where units are described in column 4 as m2, the unit shall be applied as being is respect of the floor area of the building work measured to outside of walls; and
(c)	if column 4 stipulates a relevant variation to this method, this method as varied shall be applied: and
(d)	where the building work involves more than one category or type the rate for each category or type can be used.  For example where the building work involves a residence with verandah and attached carport the lower rate for the area of the verandah and carport can be used.
Note, section 5 provides for where certain tax amounts must also be applied to the estimate in the case of certain kinds of building work.
5.
In cases where an element of the building work does not correlate with a description in the schedule, the method to calculate the estimated cost may be varied as follows—
(a)	 the cost of building work specified in a relevant written contract, less goods and services tax (GST), may be used as the estimated cost of the work for the extent of the lack of correlation; or
(b)	if there is no relevant written contract, the cost of the work, net of GST, determined and certified by a qualified cost estimator or qualified quantity surveyor may be used as the estimated cost of the work for the extent of the lack of correlation; or
(c)	if the ACT construction occupations registrar is not satisfied that the cost set by a written contract or determined by a cost estimator or quantity surveyor is fair and reasonable, the estimated cost of the building work is an amount agreed to by the registrar and the applicant for the building work, or, if no agreement is reached, an amount that the registrar considers to be fair and reasonable.
The amounts mentioned in the schedule do not include an allowance for any GST payable.  In the case of a class 1, 2 or 10 building, the method mentioned in section 4 of this determination must be adjusted by adding the applicable rate of GST to the amount mentioned in schedule 1, column 4.
