Lesson 28 : Cost Estimation Of The House

Factors To Be Considered During Preparation Of A Detailed Estimate

1. Quantity of materials: For a large construction, a large quantity of materials is required and this can be purchased at a rate cheaper than the rate of materials required for minor work. Therefore, rate of works should be framed considering the volume of work.
2. Availability of materials: Estimated cost of a particular item is higher than the scheduled rate if there is no assurance that the materials will be available as and when required, and it is detrimental to the progress of the work if the workers and maintenance staff remain idle for paucity of materials.
3. Transportation of Materials: If smaller quantity of materials is required to be transported to a considerable distance, the proportionate cost of transportation becomes higher in comparison with the cost of a large quantity transported at a time.
4. Location of site: If the site of work is located at an odd place for which loading, unloading, stacking and restacking of materials are necessary, several times, due to different kinds of journey, the point of damage or loss in transit should be considered carefully.
5. Local labour charges: Skill and daily wages of local labourer should be considered before preparation of a detailed estimate.
