The Impact

The growing use of professional construction management has been synonymous with the development of new project delivery systems such as the phased construction approach and the fast-tracking technique. This paper establishes the distinction between these two types of approach which have become increasingly popular for reducing project duration. The paper further illustrates, through a case study, the possible consequences of compressing and overlapping design activities in a fast-track program to expedite project delivery. A delay analysis shows the impact of this accelerated technique on construction activities. The far-reaching effect of mistakes during the early design/engineering phase in a fast-track program is usually underrated. Accelerating a project through fast-tracking is a major decision, and construction professionals often are not aware of its implications. Based on the case study examined in this paper and other fast-track constructions previously analyzed, trouble areas requiring special attention have been depicted and recommendations with regard to the effective use of this technique are presented. It has also been shown that if intensified effort on problem areas is lacking, such a popular accelerated technique could result in unexpected delays. Key words: fast-tracking, phased construction, professional construction management, design management.

Urban geology is a preliminary study for the construction and development of cities, which has been more prominent in recent decades in some countries despite its long application history. It assesses the impact of geological and natural phenomena on urban space and available structures. The earthquake on Nov. 21, 2017, inflicted a lot of damage to the city of Sarpol-e Zahab, west of Iran, including financial losses and casualties. Reconstruction of this city and planning for its sustainable development entail conducting urban geological studies. In the present study, the effect of natural phenomena on Sarpol-e Zahab County was studied by investigating its geology and geomorphology. The results showed that, in addition to the earthquake that habitually affected the city of Sarpol-e Zahab, the hazards of other phenomena are also significant. Recorded horizontal acceleration in the recent earthquake confirmed the high seismicity of Sarpol-e Zahab has.

Technique Comparison

Fast-tracking is an important process to speed the delivery of construction projects. To support optimum fast-tracking decisions, this paper introduces a generic schedule optimization framework that integrates four schedule acceleration dimensions: linear activity crashing; discrete activity modes of execution; alternative network paths; and flexible activity overlapping. Because excessive schedule compression can lead to space congestion and overstressed workers, the optimization formulation uses specific variables and constraints to prevent simultaneous use of overlapping and crashing at the same activity segment. To handle complex projects with a variety of milestones, resource limits, and constraints, the framework has been implemented using the constraint programming (CP) technique. Comparison with a literature case study and further experimentation demonstrated the flexibility and superior performance of the proposed model. The novelty of the model stems from its integrated multi-dimensional formulation, its CP engine, and its ability to provide alternative fast-track schedules to strictly constrained projects without overstressing the construction workers.

Paper and PowerPoint presentation format will describe process for much faster logistics and construction management of new high speed track construction and improvement of existing FRA track from FRA Class 4 to Class 5 and Class 6 standards on existing freight railway lines. This process involves an integration of the long materials supply chain together with rapid process state of the art construction machines. These machines have been used in both European and Chinese high speed construction projects. Huge gains in new track kilometers and miles per day have been made in the last decade on the machinery side of the equation. The authors will show several case studies. The critical key to these production rates has been in the integration of materials ordering and prepositioning. The economic advantage is that track time construction windows that delay other passing trains can be reduced at tremendous savings in service and operational costs to the operators already providing service in these new high speed corridors and construction zones. Examples and calculations are shown.

Pavement Layers

The Mississippi corridor of Interstate 269 (I-269) is located in northwest Mississippi and construction of this corridor encompassed approximately 27 miles of new Interstate. This study documents I-269 as a case study of the chemically stabilized soil pavement layers. The evaluation comprises pre-construction activities (material selection, mixture design, pavement design, contract information), construction activities (processes, specifications, as-built quality), and an assessment of three cement stabilized base sections. Detailed assessment included on-site specimen preparation using the plastic mold compaction device (PM Device), core drilling, and subsequent laboratory testing for density, unconfined compressive strength, and elastic modulus. This project was able to document and quantify density variability within current Proctor and nuclear gauge practices to the point where there was noticeable agency and contractor risk. Variability is known to exist in large construction projects, but quantifiable measurements over a large project, as presented in this paper, are more valuable than general expectations for basing future decisions. This paper provides evidence that a construction quality control program where nuclear gauge and Proctor compaction practices are interconnected with mechanical property measurements taken on specimens fabricated with the PM Device is worth considering for implementation. The PM Device fared well for construction, mixture design, and pavement design activities when benchmarked relative to the density, strength, and modulus of the several dozen cores taken and assessed from I-269.

The aim of this paper is to examine students’ performance in a computation-based course by evaluating the effects of key factors including sketching, visualization resources provided to them during the lectures, their attendance and tutors’ experience. A systematic review was conducted including 192 articles published during January 2010 to December 2019. Further, a case study has been conducted in which 633 students from non-engineering backgrounds were taught a core course of construction over three-yearly sessions from 2017 to 2019. The performance has been assessed through two quizzes of 10% weight each, assignment of 40% weight and a final exam with 30% weight in 2017-18 and 40% weight in 2019 were utilized with an attendance criterion of below 75% as low attendance. The statistical result highlights that a clear difference of 14% overall marks exist between the students with less than 75% attendance and the ones with 75% and above in 2017 and a 10% gap in 2018. Students with high marks in sketching secured higher overall marks as compared to others highlighting that the sketching skill is useful to construction students. The findings contribute to the body of education knowledge by evaluating key influential factors and provide a useful benchmark to other educators in the field.

The crisis in construction industry are deemed a negative event in the security, economic, political, materials, or natural affairs, especially when they occur abruptly, with little or no warning; and it has always caused damage, therefore crisis management is necessary to order not turn crisis into a disaster. The present study focuses on exploring the impact of the crisis in construction projects by offering a review of the literature to identify the various associated crisis and made a case study of ‟Khuzestan province (Iran). First, through a questionnaire survey with construction experts as respondents, the initial list of 222 sub-factors were confined to a list of 174 essential crisis sub factors and were grouped under 20 main crisis factors. Second, the shortlisted 174 essential crisis sub factors conduct a questionnaire-based survey with top experts from ‟Khuzestan province (Iran) construction organization as respondents to obtain the Importance of each sub factors based on the rating of its impact the second list and using CRITIC method to weighting crisis factors. Third, ranking the influential sub crisis factors from the all sub factor list and provide a single list without considering the initial list crisis through WASPAS model. Finally, The result of the crisis effects rating, seen that the most crisis effects rating in the Khuzestan construction industry is the economic crisis, followed by the market and real estate, and then insurance, maintenance, after that respectively, logistics, and materials crises. Identify the crisis is the main part of crisis management; the obtained results help construction crisis managers and all stakeholders to achieve sustainable development in construction projects. Identifying and prioritizing construction-specific crises allow sustainable crisis managers to concentrate to be successful projects.
