#24 - BIM and Construction Management - 1

A digital illustration of the physical and functional characteristics of a facility is built, analyzed, documented, and assessed virtually by means of Building Information Modeling, then revised until the most effective and efficient model is finalized. BIM is not only a virtual model but also a virtual database for a facility. Thus, this data can be used by construction managers in realistic ways.

The most effective use of budget, effective project scheduling, the control over the scope of work, reducing delays, and enhancements, improving the design, reducing disputes, and construction quality are included in Construction Management. Project information is of higher value to any construction manager. This information is accessed by frequent meetings, reports, blueprints, and work schedules, and later, CMs coordinate the project based on this information. But, gathering and preparing the information can be time-consuming and this information may include human errors. Traditional methods fall behind when monitoring complicated projects. Improvements in Information Technology permit to access more precise and visual information for construction managers. Which results in ineffective monitoring of the project. This proves that development in the IT industry has affected the duties of AEC professionals. Automation has improved the speed and accuracy of management. Access to information and communication between parties is improved by the cloud-based system. A virtual representation of budget, schedule, risks, and constructability is made possible before execution is done. This permits construction managers to perform their duties more accurately and with great speed.

Budget Management

All project-related cost aspects are incorporated in Budget Management. It is the responsibility of the construction manager to generate, verify, track, and document all budgeted costs from the initial stage to the final stage of accounting. The planned budget prepared by the construction manager before design begins becomes the reference or financial guide as the process moves further to the bidding phase. After bidding is done, the finalized amount of the accepted contractor’s proposal becomes the construction phase budget. As construction progresses, all expenses are accounted for in detail.

Cost estimating is one of the critical parts of budget management which includes preparing an estimate of materials and various resources required to complete the project. Building Information Models can be used for cost estimates which can be further useful for Bill of Quantities. Cost estimating software can also be integrated into models, so if any changes are made in models, they can be viewed in the estimated cost lifecycle. Because of this integration construction manager can get precise cost-related information for any specific activities. BIM can integrate design cost and time effectively.

Decision Management

Decision Management comprises developing interrelationships between the construction and project teams. The construction manager has the responsibility to consistently take effective decisions without alienating any team members. And project team members should take decisions cooperatively, without disturbing anyone’s project functions.

By the use of BIM tools in the decision-making process, the construction manager can guide all the team members as there is information integrated with BIM. BIM can be used for generating reports, drawings, analysis, cost estimates, simulation, and facility management, and ultimately it enables project team members to make informed decisions.

Information Management

Information Management comprises the collection, distribution, documentation, and safekeeping of project-related information. For project accountability purposes, the quantum of information generated requires a multilevel reporting structure and information storage which is an efficient retrieval system. As BIM is a database of information, the construction managers can make use of digitized documents whenever and wherever required.

Material and Equipment Management

Procurement of material and equipment from specification to installation is encompassed Material and Equipment management. Management of materials means procuring materials, inventory management, fabrication, and installation on the field. Productivity can improve extensively if the right control and management of materials are done. A large portion of the project cost is made of material and equipment, therefore right control over these resources is very essential.

Virtual simulation can be used to find out the impacts of selected materials on time and cost. Also, construction planners can use 4D models to find out appropriate equipment based on requirements. These models are also utilized to optimize site layout and improve logistics.
