“…A cascade method was proposed which extracts required data (such as quantity take-off and construction phases) from the BIM model and uses them to design a formwork system for the project [5]. Industry Foundation Classes (IFC) schema was employed to optimize formwork design of concrete walls in building construction [11]. Later, a method was proposed to increase the proportion of the modular forms to increase formwork efficiency [12].…”

The type and quantities of formwork system are necessary information for construction process of a concrete-framed building and the solution to this problem usually lays on the shoulders of specialized consulting firms or contractor's engineering department. These calculations are generally performed using available procedures and guidelines. The conventional formwork design process is manual and time-consuming, which requires considerable experience and attention to details. The emergence of building information modeling (BIM) in the AEC industry has allowed automation of many time-consuming tasks through application of object-oriented 3D modeling. In this project, a system was developed to automate formwork design process for the concrete-framed buildings. This method first extracts required data for the formwork design from the building information model of the project, which includes concrete elements' dimensions, quantities, and spatial information. It then applies formwork design rules and a database of modular formworks to determine dimensions and type of the formwork for each element. This system demonstrated promising performance in automation of formwork design in two test models.

“…By employing Equation (1), the equivalent time t e24 was calculated for a normal day of the month. The times t 50% , t 70% , and t 85% were required for the concrete to gain 50%, 70%, and 85% of its designed compressive strength, respectively, at the reference temperature (i.e., 20 • C); these were calculated using Equation (2). The times t e50% , t e70% , and t e85% were required for the concrete to gain 50%, 70%, and 85% of its designed compressive strength, respectively, at the site temperature.…”

“…The formwork must remain in place to support a concrete structure during the construction. This process must consider factors such as the class of concrete, cement type or grade, humidity, temperature, and size/type of the structural components [1][2][3]. The formwork removal time is critical to the concrete gaining sufficient strength, as well as to the cost and time management of the entire construction project; this is because early removal leads to rework, which leads to project delays [4,5].…”

Extending BIM Interoperability for Real-Time Concrete Formwork Process Monitoring

The concrete formwork process is a critical component of construction project control because failing to gain the necessary concrete strength can lead to reworks and, consequently, project delays and cost overruns during the project’s execution. The goal of this study is to develop a novel method of monitoring the maturity of concrete and providing reduced formwork removal time with the strength ensured in real-time. This method addresses the wireless sensors and building information modeling (BIM) needed to help project management personnel monitor the concrete’s status and efficiently decide on the appropriate formwork removal timing. Previous studies have focused only on the monitoring of concrete’s status using sensor data or planning the formwork layout by integrating the BIM environment into the design process. This study contributes to extending BIM’s interoperability for monitoring concrete’s maturity in real-time during construction, as well as determining the formwork removal time for project control. A case study was conducted at a building construction project to validate the developed framework. It was concluded that BIM can interoperate with the data collected from sensors embedded in concrete, and that this system can reduce formwork removal time while retaining sufficient strength in the concrete, rather than adhering to the removal time given in building code standards.

“…Hitherto, pertinent studies on the applications of BIM for concrete work have been limited to either improving supply chain management or enhancing the quality of precast components on projects [48,49], or estimating the costs of production and reducing the carbon footprint of concrete structures [23,62]. Hyun et al [41] represented the only study with the closest alignment to the topic and sought to use BIM in designing cast-in-place concrete formwork. At present, there is a notable dearth of research that explores BIM's capabilities for controlling joints, and initial attempts to provide automated procedures still remain in their infancy stages [63,78].…”
