AIQS Forms adopted by the Department to reflect its project development processes. These amendments are shown in the DHS Cost Plan Proformas.
Other cost plan elements are generally required as detailed in the AIQS Cost Control Manual.
The amounts, shown below as percentages, should get adjusted during the development of a project. For example the design contingency may only be required during schematic design stage and be reduced by half at design development and disappear altogether by the time project documentation is complete.
The allocation set out below is to be used as a rough guide for Project Budgets at the time a project is initially considered:
|
Building Works (Net) |
|
|
Consultants (varies with type, size and complexity) |
12% |
|
Time Related Costs (prolongation and escalation) per annum |
3-5% |
|
I.T. and Communications |
5%+ |
|
FFE (lower refurbishment based on reuse of items) |
8-15% |
|
Contingency (see notes on Contingency) |
7-20% |
|
Energy & Existing Infrastructure Upgrade |
5% |
|
Management Support (agency in-house resource) |
0.5-1.5% |
|
TEC |
100% |
The nominated percentages in this section represent recommended maximum allowances and are generally expected to be lower. Where these recommendations are exceeded justification, is required.
The Quantity Surveyor determines the percentage value at the outset according to the nature and quality of information available. This allowance decreases with the progression of each stage of documentation and must disappear entirely at Design Development and the Documentation stage, which utilise Cost Plan D.
Design contingencies are subject to project specific requirements; normal allowances for relevant stages are as follows:
This allowance is expressed as a percentage of the previous elements and is added to take account of factors such as the cost of transporting materials and labour and/or the loss of competition that can occur in isolated areas or site-specific issues such as confirmed access.
This allowance is for adjustments or variations during construction and would not normally exceed five percent (5%) for new work and eight percent (8%) for refurbishment work. It is intended to cover all unknowns and is monitored respectively by the Project Manager , Governance Group and the Department of Human Services.
At all stages of cost planning, the Cost Manager shall make an allowance for time related costs in respect of authorised extensions of time under the General Conditions of Contract.
All bench-mounted, mobile or other special equipment, loose furniture and furnishings shall be allowed for separately and scheduled in conjunction with the Service Provider.
The Cost Manager shall include all fitments fixed to or connected to services within a building in the Cost Plan - Elements 15 and 16, Fittings. (Refer to the Example of Area Schedule)
Generally, a budget allowance for loose furniture and equipment is as follows:
|
|
New Service |
Existing Service (redevelopment) |
|
Hospitals |
8% |
4% |
|
Community Services |
7% |
3.5% |
|
Aged Care |
8% |
4% |
|
Residential / CCUs |
6% |
3% |
Professional design documentation and supervision fees vary according to the size, nature and location of a project. For budgetary purposes, these fees for standard projects with normal procurement models would normally not exceed 12 per cent. In projects involving the appointment of a Project Manager total fees may be up to 14 per cent. This may need to be reviewed on a project by project basis.
The Cost Manager should make an allowance in preparing cost plans to cover costs associated with site agreements and industrial conditions affecting the site and the project. These should be constantly revised to reflect industry trends.
Escalation is applied to the Base Cost in accordance with a recognised industry Building Price Index (BPI). The consultant shall clearly identify anticipated BPI to be used in consideration of future costs.
An estimate of the Rise and Fall component during construction, for cost planning purposes, can be calculated as follows:
The Project Base Cost should be used. In determining the anticipated Total End Cost (TEC), the cost at the time of submissions should be first indexed up to the proposed tender date. Subsequently, the Rise and Fall component is added to the value of contract works, based on the escalation calculated on the anticipated BPIs discounted by a factor of 0.6. As the actual BPIs are established, the Escalation and Rise and Fall components should be adjusted.
The following example indicates the use of BPI figures for estimation at an early stage of the project. When detailed cost plans are produced, separation of furniture and equipment allowances and fees component would occur to provide a more accurate reflection of the actual situation.
For Example:
|
Proposed Tender Estimate (Jan 96 BPI 115) |
$5.80M |
|
Anticipated completion date (Jan 98 BPI 135) |
$6.81M |
|
Anticipated Total (Increases During Construction) |
$1.01M |
|
Anticipated Rise and Fall (0.6 x $1.01M) |
$0.61M |
|
Anticipated TEC (Jan 98) |
$6.41M |
