Exploiting Music and Dance Notation to Improve Visualization of Data in BIM

Suboptimal information sharing is a key a factor that negatively impacts the construction sector’s massive productivity gap when compared to other sectors of the economy. This is due to management difficulties, supply chain issues and rework. Building Information Modeling has been shown to improve dissemination of information but has not yet been exploited to its full potential. In this paper, we propose a new notation for visualizing project information in a BIM context. It is inspired by music and dance notation, and is designed to overcome current limitations that may cause the technology’s limited use during the construction phase. A proof of concept was implemented and tested in an experiment with stakeholders. The use of the proposed BIM notations appeared to make access to and interpretation of available data more effective and resulted in more correct responses

Cyclical construction workforce shortage : an evaluation of the current shortage in Western North Carolina

The inadequate supply of skilled construction craft workers is an issue that currently affects the performance of the construction industry. The performance of the construction industry has a significant influence on the growth of the national economy as well as citizens’ wellbeing. The challenges associated with the construction industry’s skilled worker shortage are cyclical. The cyclical nature is a result of the fact that the demand for construction in the U.S. depends on the performance of the overall U.S. economy. The current study evaluates the nature of the current shortage in the western region of North Carolina. Accordingly, the study examines the data collected by the Mountain Area Workforce Development Board, employing a survey that targeted construction firms. The authors have analyzed 46 completed surveys that were collected during the fall of 2018. Among other findings, the study reveals that the demand for laborers and licensed journeymen is higher than other construction positions such as supervisors and estimators. Also, the study shows that entry-level positions such as laborers have higher employee turnover rates compared to more experienced positions. The research could help develop a certified career pathway that provides short-term training and work-based learning opportunities for the raw construction workforce

Skill competency development strategies by a contractor

Construction skills are one of the vital aspects of construction work which is growing in importance due to skill gaps and skill shortages during different economic cycles. The aim of this study was to investigate competence development strategies by a traditional construction company within its own pool of skill resources and among its supply chain members. The study was carried out via literature review, empirical studies involving a focus study, analysis of documentary evidence supported by unstructured interviews and a report of skill development/supply chain conference. The study demonstrates how long-term skill development can be achieved through: (a) strategic capacity planning which allows high retention, continuous training, and balanced construction demand and contractor’s supply capacity over the long term; (b) updating and upgrading the knowledge base of the supply chain through conferences and training schemes; (c) strategic investment in the workforce through training, vocational and higher degrees; and (d) acquaintance with different sources of finance. This study will assist small traditional firms in building competencies in skill development and improvement. It will assist an international audience who may face similar issue with their construction firm

The changing nature of labour regulation: the distinctiveness of the National Agreement for the Engineering Construction Industry

The article addresses the changing nature of labour regulation through analysis of the National Agreement for the Engineering Construction Industry, originating in 1981. It shows how multiple spatial regulatory scales, the changing coalitions of actors involved, employer and client engagement and labour agency have been critical to National Agreement for the Engineering Construction Industry's survival

Enhancing off-site manufacturing through early contractor involvement (ECI) in New Zealand

Procurement strategies that enable early contractor involvement (ECI) in design may enhance off-site manufacturing (OSM) by overcoming previously identified barriers to its uptake. Involving constructors during the design stage can reduce the risk of design buildability issues, and standardising traditionally bespoke ECI processes may help overcome cultural resistance to unfamiliar OSM technology. Following literature review and using case studies, document analysis and legal doctrine, a two-stage ECI conceptual process model for New Zealand is proposed. This was tested and refined following feedback at a conference. The model comprises a first-stage pre-construction contract and a second-stage standard-form construction contract. Key process variables are considered with solutions to provide collaboration and transparency while maintaining competitive fixed pricing across the supply chain. Legal doctrine analysis is used to distinguish between design buildability obligations and design codes compliance. The model contributes towards the development of a standard form for pre-construction contracts

Structural Behaviour of Reinforced Concrete Continuous Deep Beams with Web Openings.

yesTen reinforced-concrete continuous deep beams with openings were tested to failure. The main variables investigated were the shear span-to-overall depth ratio, and the size and location of openings. Two failure modes influenced by the size and location of web openings regardless of the shear span-to-overall depth ratio were observed. The normalised load capacity of beams having a web opening area ratio of 0·025 within exterior shear spans was approximately similar to that of their companion solid beams. Continuous deep beams having web openings within interior shear spans exhibited a higher load capacity reduction with the increase of the opening size, similar to simply supported deep beams with web openings. Formulae based on the upper bound analysis of the plasticity theory were proposed to predict the load capacity of continuous deep beams with web openings. Comparisons between the measured and predicted load capacities showed a good agreement

Making the construction industry resilient to extreme weather:lessons from construction in hot weather conditions

The construction industry is susceptible to extreme weather events (EWEs) due to most of its activities being conducted by manual workers outdoors. Although research has been conducted on the effects of EWEs, such as flooding and snowfall, limited research has been conducted on the effects of heatwaves and hot weather conditions. Heatwaves present a somewhat different risk profile to construction, unlike EWEs such as flooding and heavy snowfall that present physical obstacles to work onsite. However, heatwaves have affected the construction industry in the UK, and construction claims have been made due to adverse weather conditions. With heatwaves being expected to occur more frequently in the coming years, the construction industry may suffer unlike any other industry during the summer months. This creates the need to investigate methods that would allow construction activities to progress during hot summer months with minimal effect on construction projects. Hence, the purpose of this paper. Regions such as the Middle East and the UAE in particular flourish with mega projects, although temperatures soar to above 40̊C in the summer months. Lessons could be learnt from such countries and adapted in the UK. Interviews have been conducted with a lead representative of a client, a consultant and a contractor, all of which currently operate on UAE projects. The key findings include one of the preliminary steps taken by international construction companies operating in the UAE. This involves restructuring their entire regional team by employing management staff from countries such as Lebanon, Palestine, Iraq, and their labour force from the sub-continent such as India and Pakistan. This is not only due to the cheap wage rate but also to the ability to cope and work in such extreme hot weather conditions. The experience of individuals working in the region allows for future planning, where the difference in labour productivity during the extreme hot weather conditions is known, allowing precautionary measures to be put in place

Inclined reinforcement around web opening in concrete beams

YesTwelve reinforced-concrete continuous deep beams having web openings within interior shear spans were tested to failure. The main variables investigated were the opening size and the amount of inclined reinforcement around openings. An effective inclined reinforcement factor combining the influence of the amount of inclined web reinforcement and opening size is proposed and used to analyse the structural behaviour of continuous deep beams tested. It was observed that the end support reaction, diagonal crack width and load capacity of beams tested were significantly dependent on the proposed effective inclined reinforcement factor. As this factor increased, the end support reaction and increasing rate of diagonal crack width were closer to those of companion solid deep beams. In addition, a higher load capacity was exhibited by beams having an effective inclined reinforcement factor above 0.077 than the companion solid deep beam. A numerical procedure based on the upper-bound analysis of the plasticity theory was proposed to estimate the load capacity of beams tested. Comparisons between the measured and predicted load capacities showed good agreement
