Well done sir, I am a young qs looking for mentorship especially in cost estimating.

I am lost in two areas in this rate breakdown
First is where the quantity per cu.m of concrete is 5.36
Second is where the plaster sand us divided by 3

I look forward to hearing from you soonest

Thank

Cost Value Reconciliation (CVR)

Image
The goal of an organization in a business environment is profit-making. However, delivering and meeting the client's requirements and expectations are key to sustaining the firm business. Effective management of cost and value is the basis for the expected profit. The cost and value are the links between the contractor and 1. The paying party or client 2. Subcontractors and suppliers (allied professionals) The scenarios 1. The contractor presents a cost to the client/ project initiator/ paying party 2. The contractor arranges, manages, and supervises allied professionals to achieve value in the project Cost is achieved through the knowledge of estimating principle, that is developing rates through (a). first principle (b). Specialist cost (c). Past experience i.e., sum. Value is the careful disintegration of bill rates/amounts into different items, packages, and frameworks that will be executed by direct workmen, subcontractors, and suppliers. The difference between the cost and va...

Many researchers have found disputes as a major cause of cost overrun, time overrun, project abandonment and severed business relationships. The complex nature of construction project, characterized with the involvement of a large number of participant for its successful completion embeds disputes waiting to happen, hence the use of ADR in resolving construction disputes cannot be over emphasized. Dispute resolution through ADR avoids what can be best described as brinkmanship and acrimony, reduces hostility and antag...
