## What is a Class D estimate?

Class ‘D’ (Indicative) Estimate: to be in unit cost analysis format (such as cost per m² or other measurement unit) based upon a comprehensive list of project requirements ( i.e. scope) and assumptions; the Class D estimate is evolved throughout the phases of the project identification stage, finally being incorporated …

## What is a Class 1 estimate?

Class 1 estimates are prepared in great detail, and thus are usually performed on only the most important or critical areas of the project. All items in the estimate are usually unit cost line items based on actual design quantities.

## What is a Class B estimate?

Class “B”: A class “B” estimate is prepared when a project is at the “Detailed Design” stage. Detailed design is defined as having a finalized space program, and having the drawings and specifications for all disciplines (architectural, mechanical, electrical and structural) complete to 99%.

## How do you find the center line method?

First, we need to calculate the total center line length of the building.
1. Total center line length = 2 x 5.3 + 2 x 4.3 = 19.2 m.
2. Earthwork in excavation = Total center line length x breadth x depth.
3. Concrete in foundation = 19.2 x 0.9 x 0.3 = 5.18 cu.m.
4. a) Brickwork in foundation for 1st footing = 19.2 x 0.6 x 0.3 cu.m.
