SLA provides Cost Management that consists of reviewing the available documentation and preparing a cost estimate of the total project at each of the following stages of design:
- Conceptual Design Estimate: Professional Quantity Surveyor will prepare analytical studies of a number of design solutions based on conceptional Design drawings showing the approximate shape and size of the proposed construction and brief outline specifications. The cost study at this stage will enable a choice to be made of the building size, shape, and possible construction materials and services systems.
- Schematic Design Estimate: Based on schematic design drawings and outline specifications, we will prepare the Schematic Design Estimate which will show the costs of each functional element of the project and their relationship to the whole. This estimate is the first cost plan and all subsequent cost planning and changes should relate to it.
- Design Development Estimate: At completion and approval of the Design Development phase, we will prepare a detailed elemental estimate which would include design information and outline specifications for all of the major systems and sub-systems. Each sub-element cost would be checked against the cost plan to confirm overall compliance with the project budget.
- 90 % Working Drawings Estimate: At 90 % completion of Working Drawings and Specifications, an estimate would be prepared for each proposed phase. This enables an overall review of the project prior to tendering and any final adjustments due to changing conditions taken into account.
In addition to the above, the cost consultant would normally monitor the drawings and specifications for the effect of changes on cost and the cost plan.
