The Integrated Project Delivery (IPD) in integration with Building Information Modelling/Management (BIM) is an optimal approach for delivering construction projects. This is, however fraught with complications, due to the inability of current cost management practices to determine fair risk/reward ratio in IPD arrangements. Previous research has established the advantages of Earned Value Management-based (EVM) method for risk/reward sharing, as well as, how Activity Based Costing (ABC) method can facilitate automating the sharing process. This study proposes an innovative approach to exploit the capabilities of these techniques coupled with BIM in automating/optimising the process of IPD risk/reward sharing. This includes providing mathematical equations for risk/reward sharing and developing a model that strengthens IPD parties' relationships. The process is enhanced through developing an EVM-Web grid that enables the participants to easily track their costs on computers and mobile devices. To demonstrate the applicability and validity of the proposed model, it is applied on a real-life case and displays promising results in terms of flexibility in allocating risk/reward for varying scenarios.

PurposeIn this study, a critical literature review was utilized in order to provide a clear review of the relevant existing studies. The literature was analyzed using the meta-synthesis technique to evaluate and integrate the findings in a single context.Design/methodology/approachDigital transformation in construction requires employing a wide range of various technologies. There is significant progress of research in adopting technologies such as unmanned aerial vehicles (UAVs), also known as drones, and immersive technologies in the construction industry over the last two decades. The purpose of this research is to assess the current status of employing UAVs and immersive technologies toward digitalizing the construction industry and highlighting the potential applications of these technologies, either individually or in combination and integration with each other.FindingsThe key findings are: (1) UAVs in conjunction with 4D building information modeling (BIM) can be used to assess the project progress and compliance checking of geometric design models, (2) immersive technologies can be used to enable controlling construction projects remotely, applying/checking end users’ requirements, construction education and team collaboration.Practical implicationsA detailed discussion around the application of UAVs and immersive technologies is provided. This is expected to support gaining an in-depth understanding of the practical applications of these technologies in the industry.Originality/valueThe review contributes a needed common basis for capturing progress made in UAVs and immersive technologies to date and assessing their impact on construction projects. Moreover, this paper opens a new horizon for novice researchers who will conduct research toward digitalized construction.

Cash Flow System Development Framework within Integrated Project Delivery (IPD) using BIM tools Integrated Project Delivery (IPD) endeavour to revamp AEC project outcomes through a collaborative method of regulating project stakeholders' goals through creation of a platform that provide early participants involvement and shared risk and rewards. IPD does not include a tender stage to select the optimal bid, therefore, this paper presents a methodology framework to develop a cash flow approach using BIM tools. This paper adopts Activity Based Costing (ABC), due to its ability to allocate different costs precisely to each construction process. Given that the BIM and IPD target is to achieve the best collaboration among project parties, the proposed framework backing this by displaying all estimated cost data of each package as minimum/maximum estimated cash inflow, during the buyout stage, for informed decision making. This paper extends the knowledge relating to IPD implementing process, as well as, improving cost management process based on BIM. Extant literature review highlights the gap of utilising BIM tools to develop cash flow curves, as well as the IPD cost structure requirements. To demonstrate the applicability and validity of the proposed model, it is applied to a real-life case study, which displays promising results in terms of developing IPD's cash flow management approach.
