The aim of this paper is to present the design and specifications of an integrated Delay Analysis Framework (DAF), which could be used to quantify the delay caused by the Risk Factors (RFs) in Oil and Gas Pipelines (OGPs) projects in a simple and systematic way. The main inputs of the DAF are (i) the potential list of RFs in the projects and their impact levels on the projects and the estimated maximum and minimum duration of each task. Monte Carlo Simulation integrated within @Risk simulator was the key process algorithm that used to quantify the impact of delay caused by the associated RFs. The key output of the DAF is the amount of potential delay caused by RFs in the OGP project. The functionalities of the developed DAF were evaluated using a case study of newly developed OGP project, in the south of Iraq. It is found that the case study project might have delayed by 45 days if neglected the consideration of the RFs associated with the project at the construction stage. The paper concludes that identifying the associated RFs and analysing the potential delay in advance will help in reducing the construction delay and improving the effectiveness of the project delivery by taking suitable risk mitigation measures.
本文的目的是提出一个集成延迟分析框架(DAF)的设计和规范，该框架可用于以简单和系统的方式量化石油和天然气管道(ogp)项目中由风险因素(rf)引起的延迟。“发展规划框架”的主要输入是(i)工程项目中可能涉及的资源清单及其对工程项目的影响程度，以及每项工作的估计最长和最短工期。集成在@Risk模拟器中的Monte Carlo Simulation是用于量化相关RFs引起的延迟影响的关键过程算法。DAF的关键输出是OGP项目中由rf引起的潜在延迟的数量。通过对伊拉克南部新开发的OGP项目的案例研究，对已开发的DAF的功能进行了评价。研究发现，如果在施工阶段忽略了对与项目相关的RFs的考虑，案例研究项目可能会延迟45天。本文的结论是，识别相关的风险因素和提前分析潜在的延误，将有助于采取适当的风险缓解措施，减少施工延误，提高项目交付的效率。

There are frequent failures in the project delivery in time and increasing the waste in Oman construction industry. Lean Construction (LC) principles which is lean thinking in design and construction process may be a possible solution. Hence, the paper is aimed on exploring the status of the LC practices and its impact on Omani Construction Industry (OCI). The paper presents barriers, potential benefits, and the measures of suitability and acceptability of LC principles. A quantitative research approach was adopted and research data was collected using an online questionnaire survey in Oman. The data was analysed and results are presented in tables and charts followed by critical discussions. The survey found that one-third of the construction professionals have a good awareness and half of then having a higher level awareness about LC practices. More than one third of the construction organisations are adopting LC principles with a high consensus on the suitability and acceptability, and they recognised that time commitment are necessary for the successful implementation and achieve benefits. The study concludes that the reduction in project delivery time and construction at site waste is the key advantage of implementing LC priciples in design and construction stages in the omani construction industry.

Article history Received: 20 January 2021 Accepted: 2 March 2021 Published Online: 30 March 2021 3D printing with concrete is a promising new method for rapid, low cost construction. The flexural strengths for reinforced/unreinforced and 3D printed/cast concrete Warren trusses were tabulated and the failure mechanisms were reported. The types of reinforcement used were rebar(basalt and steel), and mesh (basalt and aramid). The effect of loading geometry and loading speed was measured for basalt mesh and aramid mesh composite, respectively. Due to the expected variation in flexure between samples, it cannot be said whether small differences for various tests are significant. Variation stems from a microscopically uneven surface and random inhomogeneities in the bulk of the tested material which act as a microcrack catalyst and propagator. Since the tested beams are short specimens the numerical findings of other studies will vary based on the intended design. This paper is intended to assess the performance of various reinforcements in a qualitative sense by comparing basalt reinforcement with other reinforcements. It was found that cast beams tolerated deflection better but had a similar flexure strength compared as the printed beams. The steel and basalt rebar reinforced beams had the highest flexure strengths where the traditional steel rebar reinforcement outperformed the basalt in flexure by 36% and the basalt outperformed the steel in deflection by 40%. The basalt mesh outperformed the cast and printed unreinforced bars by a small margin but had only 25% of steel rebars’ deflection at maximum flexure strength. The aramid mesh tolerated the biggest deflection out of any sample at 2.26 cm.

Design briefing plays a crucial role to the success of a building project. Some new methods of design briefing have been developed recently, but rarely integrated with Building Information Modelling (BIM). This paper presents a feasibility study of implementing BIM in the design briefing and develop a conceptual system framework to present possible functionalities and processes of BIM-based design briefing. This study started with a series of the interviews with professionals in the industry as well as academics in various universities in the UK. A thematic analysis has been carried out to analyse the interview transcripts. The development of conceptual system framework following the software engineering method presents the major functional modules and relevant datasets of an BIM-based design briefing system which identified in the interviews. The paper also discusses on both the benefit and the potential difficulties of BIM-based design briefing, although 93 % of the interviewees agree that BIM technology should be adopted in design briefing to improve the quality of design briefing process and to involve other stakeholders and POE data in design briefing.

ABSTRACT Building Information Modeling (BIM) entered the construction industry and is permeating the commercial sector. Research is being performed to expand the capabilities and applications within the industry. However, research has historically been primarily focused on the commercial sector and has seen limited study in other sectors of the industry, specifically the residential sector. This study focuses on the custom home building segment of residential construction in the United States because of the unique and complex nature of each project. These project characteristics may assist in the realization of some purported benefits of BIM implementation, like those experienced in commercial applications. Utilizing the Delphi method, industry experts identified and achieved consensus on the most common uses, benefits, and challenges they faced in their implementation of BIM. The primary uses of BIM in residential construction identified by this expert panel were design and visualization, the creation of construction documents, and quantity takeoffs. The leading benefits identified were client visualization, plan accuracy, improved client communication, and ease of plan revisions. The leading challenges identified by the panel were high software costs, the steep learning curve when training employees, and the time-consuming nature of creating and maintaining models correctly.

ABSTRACT The implementation of alternative project delivery methods (APDMs) in the architecture, engineering, and construction (AEC) industry has increased in recent years. Yet implementation of these methods requires an organizational change effort. One of the challenges facing organizations that are implementing organizational change initiatives is employee resistance to change. The aim of this study was to investigate AEC employees’ reactions to the adoption of APDMs and to examine the methods used to communicate the APDM adoption to employees. To achieve the aim, survey responses were collected from 140 respondents across AEC owner organizations in the United States. Results indicate that employees in AEC owner organizations react favorably to adopting a change in their project delivery systems. Results further reveal that increasing the use of organizational change management (OCM) practices is related to decreased employee resistance to change. Surprisingly, employee reactions do not mediate the relationship between OCM practices and APDM adoption. The findings also indicate that the most effective ways to disseminate change messages to employees are presentations, on-the-job support, and meetings. The findings of this study may be useful for change practitioners in which employees’ reactions toward the changes in project delivery methods are more supportive than resistive to change.

Article history Received: 14 December 2020 Accepted: 30 December 2020 Published Online: 31 January 2021 In this study, an experimental study and numerical calculations using fiber model were conducted for four high-strength concrete shear walls with boundary columns under low cyclic load. The boundary column and shear wall were divided into fiber elements, and PERFORM-3D finite element analysis software was used to carry out push-over analysis on the test specimens. The results show that the finite element analysis results were in good agreement with the experimental results. The proposed analysis method could perform elasto-plastic analysis on the high-strength concrete shear wall with boundary columns without distinguishing the categories of frame column and shear wall. The seismic performance of high-strength concrete shear wall with boundary columns was analyzed using the following parameters: axis compression ratio, height to width ratio, ratio of vertical reinforcement, and ratio of longitudinal reinforcement in the boundary column. The results show that the increase in the axial compression ratio causes the bearing capacity of the shear wall to increase at first and then to decrease and causes the ductility to decrease. The increase in the height to width ratio causes the bearing capacity of the shear wall to decrease and its ductility to increase. The ratio of vertical reinforcement was found to have little effect on the bearing capacity and ductility. The increase in the ratio of longitudinal reinforcement in boundary column resulted in a significant increase in the bearing capacity and caused the ductility to decrease at first and then to slowly increase.

Article history Received: 25 December 2020 Accepted: 25 January 2020 Published Online: 31 January 2021 Over the past years, there has been an expanding intrigued in building refurbishment projects because of the alter in financial conditions and the accentuation on sustainable development. Increasing demand for building refurbishment projects will lead to an increase in organizational interactions in the construction works as building refurbishment works involve interactions among many different organizations and it can cause Inter-Organizational conflict (IOC) among organizations involved in projects. This paper adopted an Exploratory Factor Analysis (EFA) approach to analyses IOC in building refurbishment projects. For this study, a fivepoint Likert Scale was adopted to ensure the instruments of the study are reliable. The researcher ultimately sent questionnaires as a web-link and email invitation to 1050 construction firms and 733 architectural firms. The questionnaire sent to managers and professionals from construction and architectural firms in Malaysia. Finally, one-hundred-seventy-nine (179) refurbishment projects formed a database for this paper. The finding of this paper shows the IOC factors that contribute to the improve the performance of building refurbishment project can be conflict during the construction stage, conflict between the client and the consultant, task expectations, basic responsibilities, final duration, project’s goals, conflict between the client and the contractor, final cost, final quality, standards of behaviors, conflict between the contractor and the consultant, interference and conflict during the design stage.

According to the container recycling institute, nearly a million plastic beverage bottles are sold every minute around the world. Plastic bottles are considered as an urban junk, however, it has shape characteristics which make them usable in construction in lieu of conventional bricks. This research promotes the use of recycled plastic bottles as eco-bricks by substituting it with the typical construction bricks. It evaluates the thermal performance of sand filled plastic bottle-walls in a comparative analysis with traditional composite brick walls. The thermal performance of the plastic bottle walls was evaluated through COMSOL® Multi-physics and the results are noted.

This research promotes the use of recycled plastic bottles as eco-bricks by substituting it with the typical construction bricks. It evaluates the thermal performance of sand filled plastic bottle-walls in a comparative analysis with traditional composite brick walls. The thermal performance of the plastic bottle walls was evaluated through COMSOL® Multi-physics and the results are noted.","PeriodicalId":39782,"journal":{"name":"International Journal of Construction Education and Research","volume":"35 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-02-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72730543","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
