Building Information models are important to perform better job of collaboration between the many stakeholders involved in a particular construction project.
The advantage of using Building Information Models are:
The software that can be used for Construction Management are Revit, MS Project, Primevera, Hit Office (ERP), Navisworks (Simulation)
Collaboration in construction means proper work sharing and better communication between all the involved parties that helps in making an outstanding project.
When there is effective communication between all the contractors, sub-contractors, architects, designers, different trades then the work assigned to all can be performed in excellent way maintaining the superior quality.
Pre-planning is the most vital thing in the process of construction. With the effective pre-planning of tasks and work assignments we can achieve:
Small scale construction projects can make use of pre-planning methods to avoid the wastage of material, to select the appropriate sub-contractors for performing the various tasks. Thus, by using the pre-planning method the rework gets reduced and ultimately the cost is reduced and project is successful.
Building Information Modeling (BIM) is a digital representation of realistic infrastructure and facilities to support its decision-making process during its life cycle.
BIM is a building development tool that is based on a 3-d model of a building created in an object-oriented modeling software. Once the model is built, it can be used to assist with design, construction, and operational tasks and as the communication tool.
5-D refers to all of the current dimensions of BIM, where the 3rd dimension is considered space, the 4th dimension is considered time and the 5th dimension is considered cost. In the future, the reference will be modified to include 6-D (procurement applications) and 7-D (operational applications).
Most contractors are likely to start using BIM through “partial uses.” The list of partial uses of BIM seems almost infinite. For contractors already using BIM, the list seems to grow daily. For those getting started, the following list represents some of the more common “early” uses that most contractors experience in their experimentation with BIM:
• Scope Clarification
• Partial Trade Coordination
• Collision Detection/Avoidance
• Design Validation
• Construction Sequencing Planning/Phasing Plans/Logistics
• Marketing Presentations
• Options Analysis
• Walk-throughs and Fly-throughs
• Virtual Mock-Ups
• Sight Line Studies
Those who are using BIM will almost universally tell you that the number of new benefits they continue to discover seems endless. Here are a few:
• Assisting with scoping during bidding and purchasing
• Reviewing portions of the scope for analyses such as value engineering
• Coordinating construction sequencing (even if just for two trades)
• Demonstrating project approaches during marketing presentations
• The ability to identify collisions (e.g., identifying ductwork running into structural members).
• The ability to visualize what is to be built in a simulated environment
• Fewer errors and corrections in the field
• Higher reliability of expected field conditions, allowing for opportunity to do more prefabrication of materials offsite, which is usually a higher quality at a lower cost
• The ability to do more “what if” scenarios, such as looking at various sequencing options, site logistics, hoisting alternatives, cost, etc.
• The ability for non-technical people (clients, users, etc.) to visualize the end product
• Fewer callbacks and thus, lower warranty costs
