A Novel Approach for Estimation

Prof. Ch.Mahesh Kumar, Asst Professor, National Institute of Construction Management and Research, Hyderabad


We all know that one of the most crucial jobs of any construction project is to calculate quantities and arrive at appropriate cost before the project starts. Though there were different methodologies and software tools to do the process of estimation, candy takes care of everything and uses first principles of estimation. The various modules supported by candy were Estimation, Planning, Valuations, Cashflow, Forecasting, Materials and Drawings. In short, it can be called as a Mini ERP Tool which is specially designed for civil engineering fraternity as all in one. Candy (A Project Control and Estimation Software) will be a big boon and acts as a solution for Builders and Contractors for Quick and efficient "Quantity and Cost Estimation" along with planning. The various commercial estimation tools available in market are ProEst, BEST, Primus-dcf, Estimator, Quest, AutoQty, Atlas, Conquest, Pricelynx, Extreme Estimating, SSupal, Quoteit, Controls Estimate and Benchmarking etc.

Estimating Methods

Estimating is basically used for evaluation of the cost of various resources, we are going to use before a project begins. Construction estimators use four basic types of estimates (Order of Magnitude Estimate, Square Foot and Cubic Foot Estimate, Assemblies or Systems Estimate, Unit Price Estimate). These types may be referred to by different names and may not be recognized by all as definitive, but most estimators will agree that each type has its place in the construction estimating process. The following figure will draw a fair idea and differences between the four types of estimation.


Since 1978, Construction Computer Software (CCS) has focused on dedicated software solutions specifically designed for the Construction industry. In 2008, after years of working together for many clients, CCS merged with BuildSmart to join the strength of the Candy Project Control system with the BuildSmart Enterprise Accounting system providing an integrated solution from first estimate to final accounts.

CCS has over 5000 users located in over 50 countries including many of the world’s largest construction companies. It is being used in Great Britain, Australia, Germany, Hong Kong, New Zealand, Portugal, Singapore, South Africa, Thailand, and Dubai.

Literature Review

Candy is a single-package, project control system designed by construction professionals specifically for the construction industry. The use of Candy in more than 50+ countries attests to the fact that this is a powerful but practical product that brings real value to its users.
