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

The relevance of Alternative Dispute Resolution (ADR) in the Construction Industry in Nigeria

Written by  Moriam Akorede Bakare (MNIQS) The term “Alternative Dispute Resolution” (ADR), is used generally to describe the methods and procedures used in resolving disputes either as alternatives to the traditional dispute resolution mechanism of the court, litigation, or in some cases supplementary to such mechanisms. Consequently, this article highlights the relevance, effectiveness and popularity of ADR in the construction industry in Nigeria. 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 antagonism, re

 Hi, This exercise has been pending with me for some time now. It is a guide on estimation for modular ceiling finishes.  The breakdown below helps to; 1. Calculate required quantities of a modular ceiling tile with grids 2. Build up your material rate for the same ceiling type Be informed that prime cost of items changes over time; it will be appropriate you adopt the prevailing market rates in your rates build-up.
