If the phases of a construction is considered as; Initiation (Feasibility, design, bidding, initiating), Planning, Executing, Monitoring and Controlling, and Closing (creating lessons learned), the things that have to done for a proper progress:

Feasibility studies,
Design and quantity survey works,
Integrating the tender documents to the system,
Creating the Unit Price database
Creating the analysis,
Bidding calculations,
Master Plan studies,
Work schedule studies
Determining the resources needed
Procurement operations
Payment Plans
Cash flow calculations
Budget and the effects of execution to the budget
Stock control
Cost Accounting
Monitoring and controlling
Production plants (Concrete batching plant, asphalt plant, brick factory, pipe factory and etc)
Inventory operations, debit balance
Depreciation analysis and indirect costs
Time Keeping,
Equipment Maintenance cards
Payment certificates of company and subcontractors
Performance reports
Progress reports
Updating work schedule
Detailed Work orders classified acoording to responsible
Earned Value analysis
Personnel Cards,
All these mentioned items are infact the responsibilities of the staff working for the project. But with an ERP system the data created by the staff for the executed work have to be entered to the system for creating detailed reports for the managers instead of writing the data to a paper and putting it in a file on the shelf up to the date when somebody asks.
In construction sector specific ERP systems, the main aim of the system is to control the cost, schedule, and the scope of the project.
In construction specific ERP systems, it is not a way to select the data to input to the system and not to input to the system. It is only possible to separate the documents from the data to file with another system. The main function of the ERP systems is the easy access of the data from everywhere at any time without the help of anyone. This is why ERP is a centralized management tool for monitoring and controlling.

The organization established to finish a project within the defined period and budget with the desired level of quality is the "Project Management". The aim of the Prject Management is to use time, money, resources with the maximum efficiency to finish the project with the optimum budget, optimum schedule and optimum quality.
The basic principles for having a successful Project Management are:
Knowledge (Command of subject)
Experience (Command of Task)
ERP Systems (Command of Data)
Causes of Project Failures are Usually Similar:
Insufficient planning of resources, activities and time
Inaccurate anticipation of cost and duration
Difficulty accessing required data
Blockage on the channels of Measurement and Evaluation
In short;
Project failures are caused by problems in the Command, Transmission, and Management of Data.
ERP makes the construction projects to monitor and control very easily because of data management. ERP lets the team to finish the project successfully compared with the planned. In management without ERP, the data may also be under control but access to data, collecting them together for preparing a report for the executed works and for a projection to end of the project is very difficult, almost impossible.
In ERP Systems, all sites and all data are under control, more important in the computer of the managers. With the light of this information the reasons for the construction companies to desire an ERP system may be summarized:

Dissatisfaction with the current system,
The need to watch and direct operations efficiently,
To oversee activities and the efficiency of units,
To facilitate Integration between activities and units,
To allow the administration access to up-to-date reports and data in as much detail and as regularly as needed,
Future plans,
Entrepreneurial plans for increasing work capacity, hence more complex operations,
Aim for different actions.
