This paper considers the problem of predicting a supply chain cost for prefabricated building construction under an uncertain situation. Based on the Activity-Based Costing (ABC) method, we establish a computational model to estimate the total cost of the prefabricated supply chain. The model can assist in not only finding the critical areas for cost reduction of the whole supply chain but also analyzing other costs of prefabricated construction projects. Furthermore, we provide a numerical example of prefabricated building construction to validate the results.

Supply Chain Costs

The effect of ‘supply chain management’ can be leveraged when benefits of collaboration within and beyond the capacities of individual organizations are witnessed. One of the primary tasks in reducing total supply chain costs is to understand where the costs occur in a supply chain and how each activity impacts the total supply chain costs. Most supply chains in construction usually involve multiple entities, each one in a different process. A rebar supply chain is one example where many entities are involved in different processes. The supply chain coordinator needs a supply chain cost model, which shows how each activity impacts all supply chain costs to reduce the total costs. The research suggests a supply chain cost model using time-driven activity-based costing. The proposed cost model was applied to a building construction project, followed by sensitivity analysis identifying critical activities. This method can be adapted to analyze other fragmented material supply chains in the construction industry.

Background: The activity-based costing system allows organizations to estimate the exact cost of their services based on the consumed resources, which in turn translates into increased efficiency of healthcare organizations. Objectives: The current study aimed to estimate the cost of ultrasound and CT scan services using the activity-based costing (ABC) method. Methods: Following a descriptive-applied design, the total cost of the most commonly used ultrasound and CT scan services in Imam Khomeini Hospital of Ahvaz was calculated using the ABC method. Data were collected using special forms and a list of services’ costs. To estimate the costs for different hospital sectors, first, the principles of determining cost proportion per service were set, and then using the direct cost approach, costs were estimated. Results: The highest and lowest differences from government-approved medical tariffs were related to the facial (523,000 Rials) and lung (133,000 Rials) CT scans, respectively. Also, except for abdominal and pelvic CT scans, the estimated cost of services was higher than the tariffs. The highest and lowest share of costs were related to the depreciation of capital equipment (1,174,490,000 Rials) and energy consumed by activity centers (952,000 Rials), respectively. Conclusions: For most of the investigated services, the total cost was significantly higher than the approved tariffs. To make medical tariffs more realistic and to continuously improve the provision of healthcare services, it is necessary to use costing techniques like ABC.

Prefabricated Building

Supply chain management is an important challenge faced by prefabricated buildings. The transfer of prefabricated modules will inevitably be accompanied by the transmission and diffusion of risks. It is precisely because of the inherent characteristics of the prefabricated building supply chain risks that the current prefabricated building completion rate is low. Based on this, the Grounded Theory is used to identify the risks of prefabricated construction projects from the perspective of the supply chain, and build a full-stage risk system; and introduce the Interpretation Structure Model Theory to analyze the interrelationship between risk factors, and obtain different risk levels; finally, specific risk control measures are proposed for deep-seated factors, which provide new ideas for the development of prefabricated buildings.

Nowadays there are several kinds of products innovations in the construction industry, one of whom is a precast concrete slab. In fact, products of innovation are not necessarily fully able to provide a positive impact, both in terms of cost, quality, time, and waste on building construction projects. Moreover, what is offered by the manufacturer of precast concrete slab has not necessarily correspond with the needs of the customer. The purpose of this study is to analyze the comparison of products in terms of time, cost, quality, and waste between projects using precast concrete slab and the same projects that were simulated using floordeck concrete slab. This research will: (1) simulate the project if not using precast concrete slab product, (2) analyze the comparison of products in terms of time, cost, quality, and waste between the real project and the simulation project, (3) calculate the benefits obtained from the use of precast concrete slab product. The use of flyslab at Pertamina Parking Building Project (which consists of three floors and two floors using flyslab) when compared with the results of the simulation project that uses floordeck concrete slab: (1) in terms of time, it can provide a savings of 12.5% of the total duration of the simulation project, (2) in terms of costs, it can provide costs savings on the total cost structure reaches 23.13%, (3) in terms of quality, flyslab constituent materials are designed to have a higher quality when compared to floordeck concrete slab constituent materials, (4) in terms of waste, on a project that uses flyslab, the amount of waste generated is much less when compared to the results of the simulation project that uses a floordeck concrete slab.

Purpose While the adversarial nature of precast concrete (PC) building construction is frequently cited in the PC building construction press, only a few researchers have investigated construction supply chain management within the construction industry. Due to the interdisciplinary transportation environment, which inevitably results in disruption, the uses of construction supply chain and recovery from construction supply chain risk must be a subject of real interest, yet transportation management research in this area is scarce. Design/methodology/approach The purpose of this study is to discuss the weakness in system approaches and their application for managing precast concrete building in the context of construction supply chain practice and how to overcome it. As a precursor to this paper, the paper reviews current construction supply chain management occurrence on PC building construction and explores the hybrid intelligent vehicle tools and techniques currently being used on such management. This paper also presents the new hybrid intelligent vehicle-based approach to manage construction supply chain risk and reduce associated tension on PC building construction schemes. Findings The findings reveal the need for more sophisticated construction supply chain management solutions which accord with the needs of PC building construction schemes. Originality/value The paper concludes by presenting a research framework for developing such a system in the future.

Abstract: Contruction project is began by the necessity of the owner who than passed on to other parties such as consultant, contractor, sub-contractor, supplier, labour that are interlinked into a chain of construction project . The relationship between these parties put contractor as the chain in this relationship, known as construction supply chain (CSC).  In CSC there are  possibilities of risks that can increase the project cost, thus impact on the declining of the contractor’s profit. These source from three flows of supply chain system, that is flow of informations, flow of material and flow of funds. This  research  aims to analysis the supply chain risks on building construction project in Bali that affect on the declining of contractor’s profit.  Data was collected using a questionnaire survey. The respondents were selected  based on purposive sampling method, covers the experst on building construction projects. The method of analisys covers risk assement and linear regression analysis. The risk assement analysis shows that there are 26 major risks (6 risk in flow of information, 16 risks in flow of material and 4 risks in flow of fund). The regression analysis suggests that risks sourced from flow of informations is the most significant  factor that increase the projects cost, therefore mitigating focused on the flow of information with develop project’s administration as shop drawing, work permits, material’s approval, completeness of contract and daily coordination.
