General Construction Process
A typical construction project should be based on the following steps to create your construction Gantt chart:
This section normally involves the project approvals; planning and formulation of existing facilities, capitals, schedules, scope and budgets etc; the design process of major components of the project; and the bidding process of the construction project.
The process is the most important part of an overall project. A project manager or team leader manages the implementation of the project according to the Contract Documents. Some other key issues and activities include the budget management, the regular meetings between parties, the follow-up notifications of all the key project milestones, the shutdowns of certain utilities, the clearance of chemical materials and so on.
In theory, this is usually the final step of a construction project when the constructor has done all remaining items and have completed all final invoice of the project. However, in reality, the customer may often review the construction Gantt chart with the team leader to check the whole project for unfinished items.
How Could I Effectively Estimate My Construction Project Cost?
The way you calculate your construction project cost and budget greatly influence the finishing date and profitability of your project. For a quicker and accurate result, you should do the following:
1. Develop your own database of costs and pricing based on the resources of your subcontractors according to specific task scopes;
2. Calculate based on the unit price for a certain period of time; for example, the weekly or monthly price times the given time schedule (without overlapped tasks). This method also works for multiple tasks or teams. However, don't calculate every piece of equipment or every hour of working labor to avoid inefficiency.
3. Consider potential influencing factors such as complex site conditions, delays in specific tasks and other difficulties that we may face during a construction project. In this case, try to put an estimated increase in percentages on your original cost or budget.
4. Regularly check and compare your data in the construction Gantt chart weekly, monthly or quarterly, and make adjustments if necessary.
