  3. INTRODUCTION • Construction projects have a significant amount of Temporary Facilities. • Temporary Facilities on site requires safety and security.

  4. INTRODUCTION Temporary Facilities (TF) • Office Accommodations Reception, General Office, Engineers Office, Project Managers Office etc. • Welfare Facilities Accommodations Canteen, Toilets, Showers, Drying Rooms etc. • Storage Accommodation Valuable and Hazardous Materials storage

  5. GROWTH AND WASTE • Layout must be planned and executed before the start of construction works. • Conflicts must be avoided.

  6. GROWTH AND WASTE Benefits of Good Quality Planning • Travel time can be minimized • In order to ensure site safety and productive working chaotic sites must be avoided.

  7. CAD MODELLING • Construction sites can be modelled as a set of interrelated objects • The relationships between the temporary and permanent facilities becomes clear. • Feedback continuous and models can be updated

  8. CAD MODELLING Main components of construction set: • Site Objects (Existing buildings, structures, power lines) • Construction Objects (Temporary Facilities such as site accommodation, storage space, workrooms, plant rooms, parking facilities) • Constraint Objects

  9. 4-D LAYOUT AND SCHEDULING • 4D modelling system is an application that allows you to create and see the construction schedule of your project all at the same time. • Construction projects are complex, and modeling software helps project managers anticipate and plan for delays and miss calculations.

  10. 4-D LAYOUT AND SCHEDULING Importance of 4-D • This system allow the users to visualize the status of the project at any stage of construction process. • Allow an intelligent and interactive 4D visualization of space usage throughout the duration of the construction period.

  11. 4-D LAYOUT AND SCHEDULING Key Benefits of 4-D • Space utilization inside multi-storey buildings is enabled  and the efficiency of projects is greatly enhanced. • Schedule data is provided at much greater speeds than was previously available. • Consistency between schedules and 3-D models are achieved by ensuring that data exchange between the scheduling and CAD libraries.

  12. VISULIZATION Most construction projects still rely heavily on paper based communication of technical material in the form of working drawings.

  13. VISULIZATION • Planning staff of the construction contractor may be required to interpret this information and then, assuming unlimited resources (men, machines and materials) formulate some type of scheduling scheme for the project • The schedule is then refined using knowledge of working capacities and outputs and the site layout is decided at this stage and tends to be largely dependent on the project working schedule

  14. VISULIZATION • 3-D geometrical model of a construction project (inclusive of all Temporary Facilities) is prepared at the same time as the planning engineers construct the associated construction schedule and a 4-D site management model is implemented which then has the functionality of being able to perform site management functions over the spatial and temporal domains

  15. VISULIZATION • 4-D Site Management Model incorporates the whole spectrum of site management activities incorporating, construction planning, resource analysis, site layout generation and management, material allocation and cost control

  16. VISULIZATION Key Features of Visualization • Conventional site planning  • Representation of 3D geometrical model • 4D visualization • Integration of symbolic and graphical data • Linkage between geometrical model and schedule

  17. CONCLUSIONS • Commercially developed software that integrates management techniques with the ongoing progress of construction contracts is now becoming widely available • the planning of the layout of the construction village is now recognized as having a significant bearing on the profitability of construction contracts

  18. CONCLUSIONS • As margins have become ever tighter (2-3% is not considered unusual) focus has shifted to ensuring that every aspect of the construction contract is planned and executed efficiently • The planning systems would be of great benefit in achieving cost control and it would seem likely that the capital cost of implementing such a system, in a large organization, would be recouped very quickly
