Freeform buildings are now designed and constructed globally because of digital design trend, advance construction technology, and landmark value. However, due to the lack of freeform building engineering and construction management experience, it has become a high risk project for construction companies. During construction stage; many design changes, fabrication defects and construction quality issues are being raise, which results project cost increase and schedule delays. This study proposes freeform optimization process to mitigate the risk from happening at construction stage. Using BIM, visualization, parametric model and automation functions, various design alternatives are made to apply curvature analysis, panelization, panelization evaluation, and panel optimization for most efficient solution.

The issue of continual poor project performance in the construction industry remains unresolved and there is need for improvement. In view of improving project performance, the study aims at investigating the frequent causes of errors in construction contract documents. The survey research design and mixed research methods were used for the study. The respondents for the study consist of 86 consulting and 98 contracting firms that have been engaged on building projects that is above one floor between 2012 and 2015. Fifty one (51) interviews were also conducted on contractors, project managers and consultants on the projects they were involved and can equally provide necessary information for the study. Statistical Package for Social Sciences (SPSS 20) was used for the analysis of the study. The study found that the frequent causes of the errors in contract documents are frequent design changes by clients, lack of adequate time to prepare documents and design management experience among others. Based on the findings, it was concluded that the causes of errors in contract documents vary from one state to the other. It was also concluded that there is difference in the causes of errors in contract documents based on types of building, services rendered by construction organisations and states in South West, Nigeria. However, there is no significant difference in the causes of errors in contract documents based on procurement method except where there is incomplete documentation or contracting organisations have overlapping activities. The study recommends that the frequent errors identified should always be prevented from occurring if cost and time overrun are to be minimized. Also since most of the causes identified are related to consultants, it was recommended as suggested by interviewees that all designs must go through quality assurance process.Keywords: Building projects, Construction, Contract documents, Errors, project performance

Reducing Energy

The duration of an object construction is considered as a parameter expressing the concentrated influence of all stages of its formation, including design, preconstruction, construction, etc. It is shown that the construction stage, as the final stage, is the most flexible and its components that include organization of construction, technology and mechanization of construction and installation works promptly implement solutions from all previous stages, consisting of a large number of various methods and ways of influencing the construction duration. These activities allow reducing energy costs and making production less energy intensive. The decisions on combining the work of the preconstruction and the main periods of construction are given as an example.

The Uk

PurposeThe UK construction industry produces up to one third of all waste to landfill. This study aims to identify specific project practices impeding the reduction of waste in construction projects as well as uncovering potential waste solutions throughout the project delivery process. The rationale being that for such a drastic reduction in waste to landfill, holistic and extensive measures would be required.Design/methodology/approachA two‐way methodological approach was used. This comprised qualitative unstructured interviews and a quantitative questionnaire survey of three major stakeholders in the UK construction industry: clients, architects and contractors.FindingsDesign factors remain the major cause of impediments to waste reduction to landfill. Critical impediments include clients making waste prevention a top priority in projects, overly complex designs, waste taking a low priority compared to project time and costs, lack of concerns by designers for buildability, among others. Critical solutions include early supply chain involvement in design process, choosing materials for their durability, early communication of design changes to all parties, longer project programmes and better lead times, among others.Practical implicationsIn all, the target of halving construction waste to landfill based on the 2008 benchmark is achievable but would require construction companies to take it upon themselves to implement the proposed solutions suggested by this study.Originality/valueThe value of this research is to provide UK construction companies with solutions to reduce waste and aid the reaching of the landfill target, as landfill is decreasing as a solution to waste. In addition the cost savings on reducing waste could be crucial for companies in this current economic climate.

With the in-depth reform of our country's economic system, the demand for professional talents is increasing in economic development. As a main position for cultivating skilled and application-oriented talents, higher vocational colleges are self-evident in the importance. As a major feature of higher vocational colleges, practical training courses play an irreplaceable role in improving the quality and level of talents. This paper takes the intelligent buildings in higher vocational colleges as an example to discuss the teaching of practical courses. With the rapid development of modern intelligent buildings and smart homes in our country, the demand for intelligent talents has increased dramatically. In the early 21st century, China approved the establishment of the " intelligent building engineering technology" major in higher vocational colleges. This major integrates computer communication technology, construction technology and automatic control technology. This major is very applicable and practical, but many higher vocational colleges were weak in practical training. Next, I will discuss some reflections on the teaching of training courses for intelligent buildings in higher vocational colleges.

Due to the complexity, high-risk, and conservative character of construction companies, advanced digital technologies do not become widely adopted in the short term, while vendors make determined efforts to overcome this and disseminate their technologies. This paper presents the methods of an investigation addressing the extremely complex issues related to the current practices of digital technology adoption in construction. It discusses how construction companies follow a specific logical process linked to need, project objectives, characteristics of the adopting organization, and the characteristics of the new technology to be adopted. The study aims to demonstrate a novel method of data collection and analysis including data and methodological triangulation techniques including the use of NVivo and AHP to explore how companies make the decision to uptake a new technology (e.g. advanced crane, tunnel boring machine or drones) by focusing on customer and vendor activities, their interactions, contributing factors, and people involved in the process. The major original contribution of this paper is to develop an innovative methodological Cube for investigating the Construction Technology Adoption Process (CTAP) covering technology adoption, acceptance, diffusion and implementation concepts. CTAP is a framework that delineates the phases of the process that customer organizations use when deciding to adopt a new digital technology and the parallel vendor activities. The significance of these contributions is that they enable vendors to understand how to match their strategies with customer expectations in each phase of the CTAP. It also provides a benchmark for new construction companies to use the current best practice of decision making. Future research is warranted to more clearly delineate any differences with developing nations or related industries such as mining and property management.
