Building Project

Modular integrated construction of high-rise buildings has shown its potential in accelerating the speed of construction, improving safety, safeguarding quality and enhancing productivity. However, due to the disruptive change to the construction process, challenges are identified to effectively plan and handle multiple lifts for hoisting heavy modules. Research on lift planning includes the development of simulation tools. However, the previous tools provided either static simulations or pre-designed animations that did not address the interactions between planners and the tools. Virtual reality (VR) offers an opportunity to build an interactive and navigable 3D environment. This paper aims to develop a userfriendly VR-supported tool for achieving effective lift planning for constructing high-rise modular buildings. First, the module lifting process and tower crane operations were analysed. Second, a VR demonstration was developed using a real-life modular building project. Third, the demonstration was used during interviews with the project team to verify the effectiveness of the developed tool. Results suggest that the tool can help optimise the site layout and lift logistics through the provided functions of collision detection and construction simulation. The findings suggest that VR-supported lift planning will contribute to ensure site safety and enhance the productivity of modular high-rise building construction.

Various challenges should be considered in the development of an effective model for the planning and control of high-rise building construction. These challenges have been identified as results of the construction process. This paper discusses the engineering planning and management control in high-rise building construction. The methodology should also be able to address the concerns and considerations regularly faced in the industry and thus providing flexible modeling, which can be used by different levels of management

Preliminary Study

High-rise building construction demands precise planning prior to actual operation. High-rise building construction has widely been planned in urban area. Curtain wall operation is one of important and fundamental operations in high-rise building construction. Curtain wall operation is composed of various activities. Precise planning is required for the effective management of such operation. Construction simulation technique has been considered an appropriate methodology for estimating construction performance which is required for the effective management of the project. However, simulation technique revealed serious limitations. Simulation technique has difficulty in preliminary modeling and application of changed conditions. This paper suggests a preliminary study for the research that overcomes traditional simulation technique limitations focusing on curtain wall operations.

Time Interaction

Combining the techniques of discrete event simulation and virtual-reality, research on real-time interactive simulation for concrete dam construction process is conducted, under the virtual-reality environment. The key technologies are discussed, including the modeling of DEM, optimization for real-time displaying of 3D scene, collision checking, real-time interaction and so on. A framework for the system of virtual-reality simulation for concrete dam construction operations based on Vega is presented. Virtual-reality supplies for construction simulation with a real-time interactive 3D simulation environment to inspect the validity of simulation model, which improves the simulation credibility and becomes a helpful tool for real-time decision making of construction operations. An example is performed to illustrate the feasibility of the system.

High Rise

A virtual reality system was developed to simulate emergency evacuations during fires. The spreading of the flame and smoke in the virtual fire was modeled based on numerical fire simulations, so that the conditions are similar to real life. The paper investigates a number of evacuation strategies in high-rise buildings and the set of human factors affecting high-rise evacuations. It also discusses the challenges that building occupants and fire departments face during a fire emergency.

Tower cranes are popular and one of the predominant methods of material handling in high rise building construction. When there is a collapse of a tower crane in a city like New York, it is very visible, receives intense scrutiny, and becomes potentially political. This paper examines a 250-foot-tall tower crane collapse during the jumping phase of the crane to increase its height in support of a multi-level building construction. The author’s investigation examines the “defective sling” claim as the primary cause of the crane collapse along with some key findings and opinions regarding the slings used to rig the collar tie to the tower section of the crane.

The Impact

The construction sector as one of the parties using natural resources in the form of manufacturing or natural material needs to evaluate the activity of the construction process. Indonesia as a developing country requires various types of infrastructure, one of which is building construction. Various studies show that the impact of the construction process produces a large number of wastes and causes a decrease in the number of non-renewable materials. One of approaches to organize those impacts is by applying the principle of green construction. In Indonesia, this principle has not been clearly defined the meaning and the size that will be used. The purpose of this research is to develop green construction assessment model for building construction in Indonesia to improve the performance of contractor in the construction process. The scoring model is developed hierarchically composed of aspect, factor, and green construction indicator using additive model. The test model was carried out in three different project characteristics, reflecting the combination of planned green construction and green contractors. The result of green construction assessment model is able to represent the fact that occurred in the construction process.
