PRELIMINARY COST PLAN PRELIMINARY COST PLAN ESTIMATES for Property Development, Additions and Refurbishment: ......... Estimate Format may be designed to suit individual Project Needs. Typically, BDSA Quantity Surveyors estimates have two main components:1. Main Elemental Costs and 2. Sub Elemental Costs.

1. Main Elemental Costs (up to 14 Main Elements) – An element describes the functional performance of a building component. A building element, e.g. roof, always performs the same function regardless of the building type, quality or location. One of the main advantages of using elemental estimates is that they facilitate easier cost attribution and cost planning, particularly early in the design process when full design details are not available. BDSA uses the following Main cost elements for cost estimating:
* . Preliminaries
* . Substructure
* . Superstructure
* . External Fabric
* . Internal Fabric
* . Internal Finishes
* . Fittings
* . Internal Services
* . Site Works
. * External Services
* . Special Provisions

For a full list of Definitions, Elements and Sub Elements Refer to the AIQS Cost Control Manual Vol1-3 (2003)

2. Sub Elemental Costs (up to 46 Sub Elements)– Sub Elements are the individual building components that make up the Main Elements. There are between 3 and 10 Sub Elements per each Main Element. One of the main advantages of using Sub Elements is that they allow cost targets to be established and costs controlled for each individual component of the building. The Sub Elements used by BDSA Quantity Surveyors include the following:
* . Floors
* . Roof
* . Columns
* . Walls
* . Windows and Doors
*
* . Wall, Floor and Ceiling Finishes
*
. * Sanitary Fixtures and Plumbing
* . Water Supply
* . Gas Services
* . Air Conditioning
* . Fire Protection
* . Electric, Light and Power
* . Communications
. * Landscaping

 

 
BDSA Preliminary COST PLAN BDSA Preliminary COST PLAN ESTIMATES Allow YOU to Develop an Appropriate Budget and Optimise Spending for various building elements.

BDSA PROJECT COSTING ADVANTAGE!

  • Current Market Prices Applied
  • Comprehensive and Easy to Understand for Individuals, Developers, Architects, Builders, Financiers, Accountants
  • Prepared according to AIQS Cost Control Manual
  • Estimates Designed to Suit Individual Project Requirements
  • Detailed Site Inspection Undertaken for all Estimates
  • Construction Costs Estimated by Qualified Quantity Surveyors

Cost Control and Bills of Quantities:

Once the Cost Targets for each Element has been established, the overall project budget may be controlled. This process of cost checking the budget against elemental costs is constantly refined as the design develops towards full working drawings.

Upon completion of the design documentation BDSA is able to provide more detailed cost estimates in the form of priced Bills of Quantities based on full working drawing and specification.

Priced Bills of Quantities may be used in the evaluation of tenders and for the assessment of post contract matters such as progress claims and variations.
