BIM Lean Waste Reduction Framework
Introduction:
The purpose of this analytical process is to incorporate a decision support system to aid in the decision making process involved in construction management to decide, which 4D BIM software application is best suited to a construction project established from a project specific set of requirements. This process involves the analysis of three 4D BIM software applications, with an aggregate score rating offered by a 4D BIM professional. Score ratings are offered for the person’s project involvement and their experiences in a professional capacity, with one of the three software applications, which corresponds to a specific project. Score ratings for each of nine 4D BIM attributes are scored on their ability to improve the CM process, the data will be used to populate and develop the computer program’s data base over a period of time. Containing relevant data, showing the evaluation of task specific capabilities and the proficiency to enable successful CM, through the use of 4D BIM technology.
It is the aim of this program to make a project specific recommendation derived from information taken from a number of 4D BIM professionals, the experience gained from the prior use of the 4D BIM software application and the relevant conclusions that were made. A series of back links will be shown that directs a person to the web site of the organisation and project for which the 4D BIM professional has based a recommendation. This information will provide others with a recommendation based on, which of the three 4D BIM software applications to use for a planned project, assessed from a number of project specific constraints and the subsequent planned 4D BIM requirements. To define a projects constraint a classification method has been developed to represent both a planned project and a completed project. To offer a greater understanding of project similarities a 4D BIM professional will offer opinions established from the ability of each 4D BIM attribute to enhance the improvement of CM, established through the use of the 4D BIM software application defined by a set of CM constraints. Both the user looking for a recommendation and the 4D professional offering a knowledge based recommendation are presented with a series of choices to define their requirements of a 4D BIM software application.
4D BIM Added Value:
Successful construction management is sometimes measured by the ability of a management team to complete a percentage of planned work to align with the project schedule. Project success can be measured upon the ability to classify, coordinate and intuitively manage three constraints known as the iron triangle, which includes time, cost and quality. Each one of these constraints having a direct influence on the other two constraints and the successful outcome of a project. Waste associated to each of the constraints can have an impact on a project, this can be wasted working hours, material waste or energy waste.
Construction projects are similar in that they all use and adapt stage planning procedures but each project is unique with its own set of problems and solutions. An organisation may have an archive of documented projects that will provide information to achieve timely solutions to similar issues, this information needs to be accessible and verifiable, which means an accurate and reliable means of storing and maintaining previous mistakes made and the lessons learnt. A strategy to reduce the risk involved with CM and provide a sustainable product that offers greater value may be achieved within a methodical and systematic approach, which promotes a collaborative environment through each stage of a project’s lifecycle.
Effective planning for a 4D BIM project in alignment with relevant industry standards can provide assurances to stakeholders that the use of 4D BIM enables a construction project with the ability to be completed through a collaborative network of project stakeholders. A collaboration process is an integral part of a BIM project, which requires informed decisions based on the employer’s information requirements. The EIR states a need for scheduled data exchanges and required 4D models from each architectural, engineering and construction discipline. Clash detection of a discipline specific 4D BIM models are merged together to update the reference file, along with review mark-ups, which are updated in a sequential process as stipulated in the EIR to correspond with the design changes that are made. This facilitates a means of sub-contractor discussions to alleviate clashes of model elements before the construction stage of a 4D BIM project.
A general understanding is that successful CM requires meticulous front-end planning to calculate the project duration through a continuous method of validation, where planned schedule productivity is compared against actual schedule productivity throughout the construction of the project. The planning process can provide a project with the ability to verify project objectives, assess possible risk factors and provide required solutions. 4D BIM is considered a powerful tool when used in CM planning, which presents the virtual construction of a federated model that incorporates each AEC discipline’s 4D BIM model, linked to the project schedule and are further defined by linking model elements to time specific tasks.
