Bidding :

Estimate of Costs is one of the important facts for the owner. What will the Prebudget of this Construction Project be? What the owner, the consultants or the project groups generally first works on, what is prepared after the quantity surveying is finished, is the Cost Estimation. These estimates, generally prepared by the Project bureaus based on the construction diagrams and the technical specifications, are actually the Prebudget in terms of quantity and finance.

If we have the point of view of the construction company; a proposal should be prepared based on this cost estimation conforming the owner's standards. The projects should be investigated and the measurements should be checked, recalculated and classified. Based on the production Analysis, Unit Prices are calculated, market values should be checked. At the same time, with a speculative work schedule, you must foresee the effect of inflation and calculate the budget and draw the cash flow tables. This requires a collective work in the company. Some does the quantity surveying and create the Measurement Database, some does the market research and create the Unit Price Database, some makes the construction cost analysis with respect to the company standards and some prepares the work schedule and create the budget and cash flow tables. The databases have to be in contact. Each data produced in one group is needed by another group.

Imagine that there are many people working in a Project but they have no contact. Who gather the data? Who evaluates the data? How can you transfer the data? With meetings?

As seen, the data should be gathered together. This is possible if you have an ERP program.

When you prepare a proposal in an ERP program;

• You should be able to watch and select all official or private, unit prices, analysis, or current price lists on the screen.

• You should be able to evaluate your proposal with different profit margins again and again in seconds.

• You should be able to create monetary and quantity reports of the resources, material requirement and purchase lists of your proposal.
