PRELIMINARY COST ESTIMATION

Abstract cost estimate, approximate cost. Used in the early phases of a project

DETAILED ESTIMATE

involves breaking down the project scope into smaller unit prices that can be priced individually

QUANTITY COST ESTIMATE

Based on the actual number of units or amount of work that needs to be provided. is based on the count or measure of the amount of work and materials needed to complete the project

BID COST ESTIMATE

Cost estimate that is submitted to a potential client in hopes of winning the job

WALL AREA = LENGHT X HEIGHT

Compute the wall area

400mm x 200mm

The standard dimensions of CHB

CHB required = WALL AREA X 12.5

Compute the total number of CHB

5-10%

A typical allowance for CHB is

Area = Length x Height

Compute the plastering area

Total area = (Length x Height) x 2

Compute if plastering both sides of the wall

Volume = Area x Thickness

Compute the Volume of Plaster

approximate estimate

The _____ is prepared from the practical knowledge and cost of similar works.

estimate

The _____ is accompanied by a report duly explaining necessity and utility of the project and with a site or layout plan. A percentage 5 to 10% is allowed for contingencies

Area Method

The_____ of Estimate is a preliminary estimating technique in which the approximate cost of a building is determined by multiplying its total floor area by the average construction cost per square meter.

Cubic Meter Method

The _____ of Estimate determines the approximate construction cost by using the total volume of a building.

building volume

The_____ is calculated by multiplying the total floor area by the average height of the Page 1of 22 structure, and the result is multiplied by the unit cost percubic meter. This methodis moreappropriate for buildings with different floor heights because it considers the enclosed space rather than just the floor area.

Linear Meter Method

The _____ of Estimate is used when construction work is measured according to its length. It is commonly applied to projects such as fences, pipelines, canals, roads, drainage systems, and retaining walls.

Direct Counting Method

The_____ of Estimate is used for construction items that are counted individually instead of being measured by area, volume, or length. These include doors, windows, plumbing fixtures, lighting fixtures, and other equipment.

Earthwork

in construction refers to the process of moving and processing portions of the earth’s surface to create suitable conditions for construction. It involves the removal, moving, and addition of soil or rock to achieve desired ground levels for the foundation of buildings, roads, and other infrastructure projects.

Pyramids

What are the prime examples of early earthworks in Egypt

Great wall

What are the prime examples of early earthworks in China

EXCAVATION

is the process of removing soil or rock from a site to create space for foundations, basements, and other underground structures.
