Carbon Emission Analysis of RC Core Wall-Steel Frame Structures

The development of super high-rise building projects has become crucial for mitigating land shortages in rapidly growing urban areas. Super high-rise steel structures, particularly RC core wall-steel frame systems, have become the preferred choice due to their superior performance, high prefabrication level, and construction efficiency. Despite their benefits, super high-rise buildings face challenges related to higher energy consumption and carbon emissions. Consequently, it is important to analyze the carbon emissions of these buildings throughout their lifecycle and propose low-carbon construction strategies. A carbon emission analysis focused on super high-rise buildings with RC core wall-steel frame structures is conducted in this study. A carbon emission analysis model is constructed based on BIM-enabled LCA through a real-world case study. The emission factor method is combined with the BIM model to calculate carbon emission. Furthermore, carbon emissions across various construction strategies are compared, with a particular focus on the manufacturing processes of the main materials. The results indicate that incorporating admixtures in concrete, along with adopting the electric arc furnace (EAF) method and utilizing recycled scrap steel in steel manufacturing, significantly reduces the carbon emissions of the buildings. Lastly, effective low-carbon approaches for these buildings are proposed.

A case study on early-age cracking of high-strength concrete construction by coupled thermal-mechanical analysis and field monitoring

The use of high-strength concrete (HSC) in constructing high-rise reinforced concrete buildings and their deep foundations is becoming more popular because of the significant reduction in member size and, thus, self-weight in structural members. However, the higher cement content in HSC may result in increased heat of hydration and autogenous shrinkage, growing concerns about forming early-age cracks in HSC structural members. This case study assessed the early-age cracking of HSC in bored pile construction of high-rise buildings. A nonlinear transient coupled thermal-mechanical response analysis was performed to evaluate the potential of early-age cracking caused by the heat of hydration generated in the HSC using ABAQUS and two subprograms, USDFLD and UEXPAN. A 3-D finite element model was developed considering thermal effects, time-dependent evolution of early-age strength and stiffness of HSC, crack strain development, autogenous shrinkage, and stress-relaxation in the analysis. Field measurements were carried out on a 3-m diameter bored pile constructed using Grade C50/60 HSC (fck,cube = 60 MPa) for a high-rise building project in Hong Kong to evaluate the validity of the numerical model. Optical fiber sensors were used to monitor the temperature changes of the pile for approximately 380 hours after casting. The temporal and spatial temperature distributions measured in the field measurements agree well with the simulations. Large thermal gradients and high tensile stress zones were observed across the horizontal cross-sections of the pile, resulting in the formation of vertical annular cracks. Based on the results of the analysis, the maximum crack widths were predicted and compared with the durability crack width limits.

Performance analysis of supply chain for construction materials at high rise building project based on Supply Chain Operations Reference Method: A case study

Abstract Supply chain management is an approach to implementing lean construction efforts to minimize construction project problems, such as cost overruns, project delays, and disputes. Implementation of supply chain management is necessary, especially in the procurement of materials. However, there is a need to measure performance during the implementation. Results of measurement can show the extent to which the project operates and use it as a benchmark to determine the end impact of a project. This study’s purpose is to measure of supply chain performance with the supply chain operation reference (SCOR) method and use the analytical hierarchy process (AHP). Compile data using an observation with scoring form based on standards adoption, categories, and SCOR metrics through key performance indicators (KPI) and structured interviews with the contractor to validate. Limited to the study is the supply chain of ready-mix concrete materials. The AHP method give the weight of the output value of the KPI. The results of the KPI measurements from the contractor’s perspective are that one indicator is still at a low value, which is a cycle time for fulfilling orders. An overall result of 84.83 from the measurement KPI suggests a “good” performance category.

Material Planning Analysis with Material Requirement Planning Method in High-rise Building Projects

Planning material supplies well is very important in implementing construction projects to ensure smoothness and efficiency. Smoothness includes thorough planning, including ensuring materials are met as planned, while efficiency aims to reduce time and cost. In this study, material planning will be carried out using the Material Requirement planning (MRP) method, using three different lot measurement techniques, namely Lot for Lot (LFL), Economic Order Quantity (EOQ), and Period Order Quantity (POQ). The MRP method is carried out to accurately calculate the amount of material needed to avoid excessive material inventory levels. After the MRP method, the most optimal number of orders and the total cost required for each lot measurement technique are obtained. The results of this study show that the LFL technique produces the optimum number of orders for gelam wood, plywood, reinforcement, bendrat wire, and ready mix concrete. Meanwhile, for materials such as lubricating oil, meranti wood, randu wood, and nails, it is optimal to order using the POQ technique.

Soil-cement columns for high-rise buildings: design–testing–construction–monitoring: A case study of green solution in Vietnam

Soil cement columns (SCCs) are commonly used to reinforce soft ground to support roads and railway embankments, or to withstand horizontal pressure for deep excavations. This study presents another application of SCCs as load-bearing foundations for high-rise building projects. SCCs with a diameter of 800 mm, length of 10 m, cement content of 350 kg/m3, and an unconfined compressive strength (UCS) of 3.6 MPa were applied. In this study, five single columns and one group constituting two columns were constructed, and core drilling and axial static load tests were conducted. The test results indicated that the SCC could achieve a load of 1,650 kN for a single pile and 3,300 kN for the group constituting two columns. In total, 1,123 columns were designed and constructed for this project. Compared with conventional reinforced concrete pile methods, a project using SCC could save 30 construction days and 20% of the total cost. Moreover, SCC can be considered a green and environmentally friendly foundation solution because it does not use concrete or steel materials and does not produce waste soil.

Accessing real-time data from the Automated Construction System (ACS) through diverse field sensors holds paramount importance in effective safety management. However, the challenge lies in overcoming inefficient data exchange and information integration. This study seeks to extend the Industry Foundation Class (IFC) standard to seamlessly integrate real-time safety information with the digital model. Our approach involves identifying the essential information required to describe ACS components and safety monitoring items, which is followed by an extension of the IFC schema to create comprehensive descriptions of safety-related data. Additionally, we devise an innovative parameter mapping technique to incorporate dynamic sensory data into corresponding ACS components within the BIM model. We present a case study of a construction project equipped with the ACS, which underscores the feasibility of our approach. Our findings hold substantial practical benefits and establish a robust foundation for future data-driven endeavors within the realm of ACS.

RISK LIST IDENTIFICATION ENCOMPASSING TACIT KNOWLEDGE FOR VIRTUAL REALITY IN BUILDING PROJECTS IN JAKARTA

A high-rise building project can be considered as a high-risk project because the work items are quite a lot and high in the structure being built, the occupational health and safety (OHS) of construction plays an important role in the smooth implementation of a construction project. Construction OHS conducts safety briefing to all construction workers when they enter the construction project environment and every morning before the construction begins. Two information systems are used to inform the workers about the conditions and hazards in the construction projects, namely tacit knowledge and explicit knowledge. Therefore, safety induction is less effective and hinders the implementation of construction project work, where construction workers do not know situations that occur when carrying out a job socialized by OHS officers. In this problem, a simulation must be carried out before workers do their work, to carry out this simulation can be done with virtual reality technology. The research was conducted by distributing questionnaires to the OHS staff of construction projects in Jakarta while the data from the questionnaires were calculated. This study aims to find out a list of risks that are still relevant including tacit knowledge and obtained 11 work risks including tacit knowledge from 38 work risks for building construction projects in Jakarta. Keywords: Construction, OHS, Risk, Knowledge management, Virtual reality.

Duration and Labor Resource Optimization for Construction Projects—A Conditional-Value-at-Risk-Based Analysis

The complexity and uncertainty of construction projects contribute to low efficiency in the construction industry. This research applied the Takt-time planning method to optimize the construction working process, and proposed a risk control framework based on Value at Risk (VaR) and Conditional Value at Risk (CVaR) approaches to explore and predict a project schedule and cost performance under different scenarios. This research selected a high-rise residential building project for a case study and collected 1672 productivity data samples. Arena Simulation models were established based on 90 combinations of labor assignments to assess Takt-time planning strategies’ impact on project performance in four scenarios. The VaR and CVaR evaluations at 75% and 90% confidence levels were compared to balance project benefits and risks. Without any overtime or additional workers, this research found a Takt-time planning method that can reduce the project duration by 20.2% and labor costs by 2.1% at the same time, using a labor assignment of 12 bar placers, 12 carpenters, and 5 pipefitters. The findings can assist construction managers to achieve a shorter duration, reduced cost, and safer work environment, which will be very effective and beneficial to improve project overall performance.

Spatio-temporal optimization of construction elevator planning in high-rise building projects

Appropriate construction elevator planning is beneficial for successfully completing high-rise building projects. Construction elevator planning typically remains unchanged throughout a high-rise building project or seldom involves the designation of service days, which causes such planning not to respond effectively to variable transportation demands and adversely affects the possibility of further optimization. Another limitation is that the installation and dismantlement dates of construction elevators, which are highly important when multiple construction elevators are used, cannot be explicitly determined in construction elevator planning. To solve these weaknesses, this paper proposes an approach to assign construction elevator cabs to serve designated days and floors based on actual transportation demands from the perspective of spatio-temporal optimization with mixed-integer programming. The experimental case study results show that the presented planning can significantly reduce the total cost when compared to other planning and can provide evidence and explanation for determining the installation and dismantlement dates of construction elevators.

Parametric Automated Design and Virtual Simulation of Building Machine Using BIM

With the continuous development of the construction technology of the main structure of high-rise buildings, traditional construction techniques have been widely used in high-rise building projects. However, these technologies have problems such as low safety, low intelligence, and poor integrity. In order to solve these challenges, the Third Engineering Bureau of China Construction independently developed a new type of construction technology—a high-rise building integrated work construction platform (referred to as a building machine). Building machines has been gradually applied to high-rise building projects due to its intelligence, integration, safety, and other advantages. However, with the increase in the number of high-rise building projects, the traditional way of designing building machine layout programs is inefficient and the design program is complicated to change. To solve these problems, this paper proposes a building machine parametric design and layout and virtual simulation method. This method uses Blender open-source software to model the building machine parametrically and quickly using its visual programming tool Geometry Nodes (GN) and simulates the building machine in the virtual scene through the Unity3D platform. The results show that, compared with the traditional design mode, the method proposed in this paper can quickly complete the scheme design in the design phase of the building machine and display it through the 3D model, which has a better visualization effect, improves the design efficiency, and reduces the design cost, and the Unity simulation platform can also provide the construction personnel with pre-shift education and simulation of the operation of the building machine. This method provides a theoretical basis and guidance for the digital construction of the building machine.
