The Building Information Modelling (BIM) implementation is to create a centralised knowledge sharing resource that contains all the necessary design and operational information about the project. BIM is a collaborative approach and integrated project delivery to design and delivery embraced by various construction teams in the construction projects. In the context of the most suitable project delivery to be used, with regards to the use of BIM, the Integrated Project Delivery (IPD) approach is highlighted as the best method which correlates building procurement of the design-to-construction business process through literature review analysis. IPD is developed as project delivery system that integrates people in effective collaborative approach between the key players in the project. IPD is going to be particularly beneficial for BIM because the contracts relation between the contractor, designers, consultants, constructors, sub-contractors and suppliers were binded and expressly determined at earlier stage. This relationship between these two subjects will helped the project team to achieve the project goals in terms of timely schedule, life cycle costs, quality and sustainability in construction project. Therefore, this study investigates on the propensity of the best methodology of project delivery system which can correlate with procurement adoption for projects adapt BIM concept. This is a descriptive study and the method used is based on review of the literature in relation to BIM and IPD. The analysis revealed that propensity of adopting IPD project delivery and the adoption of BIM are based on these factors: improve the communication, closer collaboration; liability and legal relationships are specifically determined, the best quality outcome; and lastly with reductions in design and construction period, it provides a cost effectiveness and a saving in overall construction period.

Payment conflicts are never ending issue in Malaysian construction industry. This issue is a common scenario especially in public work project, which involves a conventional contract. The late payment and non-payment occur due to client inefficient payment administration caused by documentation and human factors. It commonly ended up causing delays in project completion. However, the revolution of Information Technology (IT) within construction industry has shown the development of various management systems, which transformed the way projects are administered. The introduction of Building Information Modelling (BIM) is one of the project management systems, which have been created to centralised knowledge sharing resource as an effective collaborative and integrated approach between inter-disciplines in construction industry. The development of digital technology of Intelligent Contracts brings great potential in BIM management to automate the contractual process and thus create possible solutions towards payment conflicts in the construction project. This paper discusses the process of payment in the conventional contractual procedure, which relate to the causes of delay in payment. It is believed that by integrating BIM and Intelligent Contract’s attributes may help to eliminate the unnecessary procedure, which prolong the payment processes. Therefore, this study is carried out to explore what are the effects of adopting BIM and Intelligent Contracts attributes in conventional payment process. This is a descriptive study and the methodology used is essentially on review of the literature in relation to payment processes in conventional contract, BIM management system and attributes of Intelligent Contract. The analysis revealed that the adoption of BIM and Intelligent Contracts attributes in payment conventional process could improve the efficiency; reduce the time by eliminating third party interference and manual signatory. In addition, the project performance is analysed intelligently as well as minimise the risks of losing information by keeping historical audit trails in automatic system repository.

Conflict caused by payment issues are common in construction industry.  A lengthy payment process issue is a common phenomenon especially in public work projects, which commonly opt for conventional contracts.  Delay in payment process have caused many contractors not being able to receive payment within the stipulated time.  In turn, it may affect the contractor’s cash flow and eventually ended up causing delays in project completion. The effect of technological advances has brought significant changes to the construction industry, which is year after year becoming increasingly complex.  Therefore, in the era of technology and digital, there are many management systems which have been established and introduced amongst construction players for the convenience of managing and administering construction projects.  The introduction of Building Information Modelling (BIM) is to establish a centralised information system, which improves the collaboration, communication and integration between interdisciplines in construction industry.  The development of digital technology of Intelligent Contracts will bring great potential as an automate support system in BIM management process.  These combinations create possible solutions towards payment conflicts in the construction project, through integration of BIM and Intelligent Contracts that may help to reduce the unnecessary procedure and interference that prolong the payment process. The analysis revealed that the adoption of BIM and Intelligent Contracts attributes in payment process under conventional procurement could improve the efficiency and reduce the time by eliminating unnecessary procedure and third parties interference along the process.

Building Information Modelling (BIM) has a high potential to assist in designing a green building. Integrating BIM and building rating tools can help designers design buildings that fit the minimum requirements of green certification. Without BIM, green certifications are performed manually and after project completion. Incorporating BIM and building rating tools in the early decision-making process of a project is more significant to enhance building sustainability. The study aims to review the extent of integration of building rating tools with BIM for green certification in the current research. Upon screening the relevant publications, it is discovered that only a small number of studies have been conducted that link BIM and green assessment tools. Only a total of 19 studies are eligible for the review process. The content analysis results of these studies point out that LEED is the most used building rating tool for integration with BIM. The integration is mostly made by using Autodesk Revit and Dynamo. The major focus for the integration is on the energy and atmosphere sub-category as the credit allocation is the highest. More studies integrating the BIM-building rating tool are needed to automate the green certification process.
