PurposeModular integrated construction (MiC) is the most advanced off-site construction technology. However, the application of MiC for high-rise buildings is still limited and challenging. One critical issue is tower crane layout planning (TCLP) to guarantee safe and efficient multiple crane-lifts for module installation, which, however, has been insufficiently explored. For filling this knowledge gap, this paper aims to systematically explore the critical considerations on TCLP for high-rise MiC to support contractors in determining the optimal crane layout plan.Design/methodology/approachThis study employed a multimethod strategy. First, previous studies on TCLP and critical features of MiC were reviewed to develop a conceptual model of TCLP considerations. Second, expert interviews with 15 construction planners were conducted to identify the critical TCLP considerations for high-rise MiC. Third, a multicase study with three high-rise MiC projects was undertaken to demonstrate and verify the identified considerations.FindingsThe paper characterises critical considerations on TCLP as performance criteria and influencing factors and identifies 7 critical performance criteria and 25 influencing factors for high-rise MiC. Specifically, the features of MiC (e.g. various modularised layout design, heavyweight and large size of modules) were found to significantly affect the crane layout performance (i.e. technical feasibility, safety and economic efficiency).Originality/valueThe paper is the first-of-its-kind study on crane layout planning for high-rise modular buildings, which contributes a two-stage multicriteria decision-making framework integrated with systematic TCLP considerations. The findings should help contractors determine safe and efficient tower crane layout plans for high-rise MiC projects.

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.

Crane Selection

Modular construction, which involves unit production in factories and on-site work, has benefits such as low cost, high quality, and short duration, resulting from the controlled factory environment utilized. An efficient tower crane lifting plan ensures successful high-rise modular project completion. For improved efficiency, the lifting plan should minimize the reaching distance of the tower crane, because this distance directly affects the tower crane capacity, which is directly related to crane operation cost. In situations where units are lifted from trailers, the trailer-to-tower crane distance can have a significant impact on the tower crane operation efficiency. However, optimization of this distance to improve efficiency has not been sufficiently considered. This research proposes a genetic algorithm optimization model that suggests optimized tower crane and trailer locations. The case study results show that through the proposed model, the project manager can reflect the optimal location selection and optimal tower crane selection options with minimal cost.

Safety is essential for tower cranes in construction engineering, as the inner-climbing tower crane is widely used in the construction of high-rise structures, design safety, reliability and support system which can be turnover is an important prerequisite for protecting the safety of construction. By understanding the interrelationships between construction environment of Henglong Plaza Twin Towers in Shenyang city and ZSL2700 tower, the article will analyse the support system for the project. It mainly uses finite element analysis software ANSYS which can create mechanical status of modeling to analyzing the supporting structure. It can guarantee the structures rationality and the security reliability. Project Summary Shenyang municipal government square tower engineering which building height is 350.6m has the underground layer 4 and the ground 70 layer. The office building has used the frame core tube structure system. The outside frame is composed by the square shape section coagulation earth pyramid and the peripheral steel girder. The rectangular core tube was the reinforced concrete, while in the core tube outer wall has established some steel pole. This project adopt two boom tower cranes from Zhongsheng construct machine company (Nanjing).The first number tower crane is ZSL750, which maximum torque is 750tm; the second number tower cranes is ZSL2700. This paper takes the ZSL2700 tower crane as an object, studying this machines stressful condition of attachment system. The ZSL2700 tower cranes most high-torque is 2600tm, pitching arm angle ranges 85-65 .The maximum lifting load is 100t. The biggest hoisting up scope is 55m, which lifting load is 37.6t.When the crane surpasses the permission lifting load or the hoisting up moment of force, PLC can break the power implementation protection automatically. The tower machine need carry on 19 climbs in the construction process. Fig. 1 Two tower crane installation location diagram
