machines, or new staff with better skills and education can help project managers improve their planning of the project, scheduling and organizing during the work progress, cost control, quality management and co-ordination techniques helps in project performance.

6. Institutional influences: professional institutions can affect the conduct of their members through conditions of engagement, fee scales, etc. Professional codes of conduct and education regulations can affect project organization and decision-making processes.

7. Physical conditions: the external physical conditions may significantly affects the perform project performance. Factors to be considered here includes the infrastructure/transportation, degree of saturation, district …show more content…

Acts of god/force majeure: any uncertain activities such as the impact of Environmental forces such as flooding, earthquake and other weather conditions can have obvious ramifications.

2.3 Different Planning and Controlling Techniques in Dynamic Environment:

2.3.1 System Dynamics:

System dynamics is one of the method used for the modelling, analysing and to study the behaviour of complexity in the social systems that arise in construction industry. It has been used to study the various socio economic and environmental systems, where a feedback loops are vital to study the interrelationship between activities. The approach has attracted attention in now-a-days since the application of computer software has been widely used and readily available and helps in communicating the dynamics of systems with respect to the Project managers. Figure 4 illustrates the features of an influence core of the system of a dynamic model. The arrows in the figure represents the influences among the different factors; the “+” or “–” signs indicates whether the changes are positive or negative in the preceding factor has a positive or negative effect on the next activity. This example contains one main and two subsidiary balancing feedback loops, as emphasised by the "B-"loops. In practice the balance is not so easily achieved and there may be a number of disruptive Factors, as summarised in the boxes of Figure 4 systems, where a holistic view is important and feedback loops are critical …show more content…

Currently Construction industry is now focusing on application of IT (information technology) in the projects so as to overcome the different dynamic environment situations as discussed earlier in the chapter 1. Computer-assisted tools form two-dimensional diagrams, such as bar charts or critical path network charts, which lack in the proper visualization with respect to the actual construction and have been used to represent construction schedules and track the activities from time to time. The resource management and workspace requirements, which are not shown in detail on the two dimensional frames are usually coordinated mentally. The visual representation of construction site which includes the progress of the building works and status of the use of site space and requirements as time elapses, will not be available in 2 dimensional diagrams. Thus, planners have to rely on their experience and intuition, imagination and judgment to extract data from paper-based design documents and to decide upon the appropriate method of construction, its timings and the site usage layout. The main aim of application of IT in the construction industry is to overcome the above discussed factors and some of the IT applications that are being applied in the construction projects are discussed
