Developing long period models for improved concrete design

There are hidden costs associated with the recent surge in the use of fresh concrete supply to ongoing construction systems. As ignored as they often are, it is important to factor them when developing a financial model analysis when designing projects that involve their use. Benefits of this would include reduced total cost and improved operational efficiency.

Financial Estimates

Estimates for project investments are usually targeted at about 30 to 50 percent of actual project expenses.
Generally, the project being conceived is usually compared with existing projects of similar magnitude. The one closest in terms of manpower hours , electricity or gas consumption is then compared with and the costs used as a guide. These cost indices form the basis for many construction initiatives require huge capital outlay.

Let's analyze a situation where it costs 2 000 000 dollars to build a home in an area (in the year 2010) with historical cost index of 102.2.

This HCI is also estimated to become 114.3 by 2012.
With CCI estimated at 123.4 and 134.3 in different areas at the different years, building costs is estimated to become 2 430 000 dollars in value.

Formula for obtaining future cost is HCI ratio * CCI ratio * Building Cost.

Therefore, using fresh concrete technology (which have their setting times known and provided upon their delivery) can come in handy in preventing future expenses that could be incurred in construction.
