Supply Chain Operations Reference (SCOR) is a supply chain performance measurement model that has been widely used in the manufacturing industry with the latest model version 12.0. This article presents the adoption and development of a construction supply chain performance measurement framework in Indonesia based on SCOR 12.0. The supply chain supply for ready mix concrete and steel as a case study consists of contracts, on-site inspection, material usage, and payment. Simulations were carried out on Project X with precast concrete supplied by ready mix concrete and steel with three suppliers each. Performance indicators from SCOR are analyzed and simulated to be implemented in the supply chain flow. The result is a contract phase with overall value at riks (OVAR), on-site inspection with perfect order fulfillment (POF) and order fulfillment cycle time (OFCT), use of materials with upside supply chain adaptability (USCA) and downside supply chain adaptability (DSCA), payment with total supply chain management costs (TSCMC) and the cost of goods sold (COGS), and overall flow with cash-to-cash cycle time (CCT), return on supply chain fixed assets (RSCFA), return on working capital (ROWC).

The 4.0 industrial revolution in all fields encouraged the construction industry to make technological-based innovations. Building Information Modeling (BIM) is one of the tools in advancing construction technology today. On the other hand, supply chain construction continues to grow and becomes important in project management. This study aims to identify the potential use of BIM in construction supply chain management. Preliminary studies on several projects in Indonesia were carried out as identification methods. The Delphi process was used to obtain the data described in the Strength, Weakness, Opportunity, and Threat (SWOT) analysis. As a result, BIM has the potential to be applied to the construction SCM with several considerations. There are 5 trends in strength, 4 trends in weakness, 5 trends in opportunity, and 3 trends in threat. Trends in strength and opportunity are used as indicators in the analysis of impacts. BIM as advanced technology is the highest indicator and the lowest trust between stakeholders in the application of BIM in the construction supply chain. In addition, harmonization between BIM actors is needed: the Ministry of Public Works, contractors, suppliers and academics in the supply chain.

Precast concrete has typically long lead time, starting from order placement, production stage, to delivery to project site, all of which requires good supply chain management. As a consequence, the risks of its supply chains are inevitable and must be anticipated to ensure the success of a project. The aim of this research is to assess the risks of the supply chain of precast concrete from production to delivery to projects. WKB, a government-owned company that produces precast concrete, has been used as the case study. Activities along the supply chain were mapped based on five dimensions of Supply Chain Operation Reference (SCOR), i.e. Plan – Source – Make – Deliver – Return, upon which risks were identified. Data was collected through in-depth interview and questionnaire survey to key persons of WKB. A 1-5 Likert scale was used to quantify the occurrence and severity of risks along the supply chain. The identified risks were classified into four levels based on the multiplication of the occurrence and the severity, i.e. critical, major, moderate, and minor. A total of nine critical risks were found along the supply chain, i.e. sales forecast and planning for production (Plan); production capacity of natural material vendors (Source); sudden change of production, shortage of skilled workers, additional cost for land stockyard rental, and renewal for industrial land lease license (Make); risk of non-standard transportation (Deliver); defective and failed products (Return). This research provides a valuable understanding of the risks of the precast concrete supply chain and the mitigation strategies.
