What are my building costs?! The #1 burning question on everyone&#;s mind, when building a commercial or industrial develeopment.
Along with, what is the price of tilt-up per square meter? And how long will it take to build my project?
For more information regarding building timeframe, click here.
The question of how much will a building cost, is a bit like the question &#;How long is a bit of string?&#;
That is until you/we know certain parameters such as;
1) How big is the building?
2) How tall is the building?
3) Is there an office component or is it all open warehouse or factory?
4) Are there multiple storeys or just a single storey?
5) Are there any special requirements (cranes, floor loads), large or heavy-duty external hard standing
areas?
6) What size lot is it on and what is the plot ratio (or external works area component to the building
floor area works component)?
7) If they are factory units, the individual unit size can be important as you could build the same overall
building area with 5 larger units.
As opposed to 10 smaller units and have a vastly different cost outcome.
8) Which local government area is it being built in?
As development requirements and constraints can vary greatly between local government areas.
9) Whether the design work is included in that cost, or whether a fully specified consultant design will
be provided.
If so, what level of spec the building has been designed to?
These are just some of the considerations when you are thinking of building. Not everything you put into a building will necessarily increase its floor area.
If you increase cost without changing the floor area, the cost per m2 will inevitably go up.
The next question by most of our clients is generally along the lines of &#;ok so, what is the cost of a standard build that you do?&#;
The short answer is, there is no such thing as a standard build. Each one of our builds is different.
However, if we picked some parameters such as:
&#; Design costs and approvals fees included;
&#; A standard 125mm thick wall panel;
&#; A 7.5m maximum parapet height;
&#; A unit development of 2 units at approx. 55% plot ratio on the site, each just under 500m2;
&#; A single basic disabled toilet with no shower and floor tiling with 200mm skirting tile, in each unit;
&#; With bare minimum electrical
&#; switchboard, power point for tea bench, 1 hi-bay light, emergency and exit lights;
&#; Manually (chain) operated roller door (or doors);
&#; Instantaneous electric hot water unit;
&#; Minimal shopfront glazing; and
&#; No landscaping or fencing included
Then, we are we can start to give you somewhat, of an idea of building costs.
In the past, we have built a similar project to this recently, for around $550 (+ GST) per m2.
However, we built a similar project with one change &#; the average unit size was 120m2, in lieu of 500m2 and the price went up to closer to $1,000 per m2.
As you can tell, it is very difficult to put a rough metre rate budget on such a build. We need to know the without complete parameters of what the client wants, in order to give a close to an accurate estimate.
We would ask a few questions and quote a range along the lines of;
1) $650 &#; $750 per m2 for factory units (depending on size and spec);
2) $550 &#; $650 per m2 for general larger warehouse spaces with no office component and no
sprinklers and not over height;
3) $1,250 to $1,750 for office space built as an adjunct to the above warehouse development but as a
bare shell with wall linings, ceilings, no A/C or floor treatments; and
4) $75 &#; $100 per m2 for sealed drained concrete or bitumen carpark built at the same time as the remainder of the project.
There are some factors that are going to change those prices fairly drastically.
For example;
&#; if a warehouse needs sprinkler, is of a steel frame, full concrete construction or is intended to be
higher than a standard 125mm (7.5m high) panel might permit, this will increase the costs; or
&#; if the warehouse was a workshop and required a heavy capacity craneage to be installed;
&#; Where an office is for consulting rooms, and are fully fitted out with partitions, carpets, air-
conditioning etc. With additional plumbing and finishes &#; this can run to in excess of $3,000 per m2
depending on the final design.
&#; Any part of the above project is being done as a standalone project or stages (not getting the benefit
of shared walls/supervision and site/job costs etc.
&#; Where the design consultants have been heavy-handed, on the design work in building additional
cost in the fixed cost side of construction (material and labour components) which the builder
generally has no control over.
We are always reluctant to quote our clients budgets based on arbitrary metre rates. This could lead to a disaster, where a client will take the step to buy land (based on a meter rate budget) only to find that there are significant cost and budget issues in the future.
In lieu of quoting metre rates, we offer a no-obligation budgeting exercise &#; where we will provide a sketch of the development proposal, on a lot and prepare a budgeting estimate. We will perform a take-off of, the work we expect to be necessary to complete the remaining design and construction of the development.
The budget roughly calculated through this process will be very close to the final cost of the development &#; barring any scope changes.
This process had the added benefit of allowing us to shape the development, to a budget that you may have that will work for your development cost plan, financial capacity and/or business. This works best when, you are prepared to share your project budget and ideal outcomes for the development with us at this early stage.
Once you have your completed budgets and if the development stacks up, we can discuss what further steps we can take to lock down a final price for the work and proceed further.
If you are interested in enquiring in relation to a potential commercial or industrial construction project, we would be happy to assist.

The idea of building upwards not outwards, particularly in city centres, can be highly attractive. But doing your calculations before digging into the ground can save digging deep into your funds.
You&#;ll also need to factor in crucial points such as the location above and below ground, the weather and infrastructure.
It&#;s virtually impossible to calculate the cost of building a skyscraper, due to differences in building sizes and their overall weight as well as their location, just to name a few.
But a very basic way to calculate the cost is by multiplying the intended building&#;s entire floor plan area by a per square metre figure.
This figure is based on the building&#;s suburb and location with the latter in particular having the potential to change, depending on the geography and geology according to the Australian Institute of Quantity Surveyors president, Mark Chappé.
Using the example of a 25-storey CBD building, the costs would differ according to which capital city it&#;s built in:
between $3,500-$4,50 per sqm
However, Mr Chappé warned this calculation was a basic benchmark, and other factors needed to be taken into account to discern final costings.
&#;We tend to work on some very simple principles of buildings, which we call elemental cost planning or cost estimating,&#; he said.
Solid substructures will allow for the vast weight, or mass, of high-rise buildings.
Building on sand or on a water table will mean digging deeper &#; and expending more funds &#; to reach firm bedrock.
This was the case in one of Australia&#;s tallest properties, Australia 108, which was recently competed at Southbank, on Melbourne&#;s Yarra River by architecture firm Fender Katsalidis.
Director James Pearce of Fender Katsalidis said the riverfront site&#;s sludge and silt meant the tower&#;s piles &#; otherwise known as below-ground, support-bearing structures &#; had to delve far lower than usual to reach a solid foundation.
&#;We also had to be very careful to avoid basements &#; because you&#;d have waterproofing issues,&#; he said.
Mr Chappé said such digs couldn&#;t always be completed, due to potential damage to surrounding buildings, while finding suitable foundations below a water table could be unachievable.
If digging below a site isn&#;t possible, constructing car parks can also be an issue or require extra funds and forethought.
While car parks can be built above ground or similar, Mr Pearce said such areas were best constructed out of sight, or at least off the street; however, even above-ground car parks could be cleverly and stylishly hidden.
&#;We&#;ve hidden Australia 108&#;s 10 levels of above-ground car parks by designing screening balconies of canary palms that project outwards,&#; he said.
According to Mr Chappé, super-sized buildings such as Australia 108 can easily be affected by strong winds or wind loading.
He said such weather pressure could see the top of high-rise properties swaying like a sail.
&#;You have to take this into account in terms of the property&#;s structure, as this can raise additional costs,&#; he said.
&#;With any tall building, you&#;re going to have to consider the facade too and what it&#;s made of because, at that (wind) speed, water can get into a building quite easily.&#;
Mr Chappé explained lifts&#; construction had to be considered carefully particularly with extremely tall properties as they needed extra space for additional, and faster, lifts along with a very strong, central building core.
&#;This core will need to be a lot bigger than it is for another type of building, so that is going to need to be considered in the costs,&#; he said.
Then there&#;s the sewerage and hydraulics needed for water installation while a skyscraper&#;s walls and columns need to be wider and stronger due to the massive total weight of the building.
While they may not take increase skyscraper costs, obtaining approvals can definitely escalate construction times.
Mr Pearce explained that due to its 319-metre height, Australia 108 needed both council and Civil Aviation Safety Authority (CASA) approvals.
He said CASA allowed the cranes of the high-rise project to work just beyond the limit of its Procedures for Air Navigational Services &#; Aircraft Operations (PANS-OPS) point, but only for a short time.
&#;CASA gets involved in almost all of the tall buildings these days,&#; he said.
&#;You can build buildings taller (than their limits) &#; but you just need to get CASA approval for it.
&#;This is a formality really but it does require extra work to be done.&#;
