It is well established that the project cost, quality, safety, and duration are four critical elements contribute to success. Past literature has theoretical relationships between construction safety quality on basis of opinions industry experts. This first empirical inquiry into relationship testing null hypothesis there no statistical among performance indicators indicators. To test this hypothesis, data were collected from 32 building projects, ranging in scope $50,000 $300 million...
This paper presents the specification, design, and development of Visible Camera (VIS) on European Space Agency's mission. VIS is a large optical-band imager with field view 0.54 deg$^2$ sampled at an array 609 Megapixels spatial resolution . It will be used to survey approximately 14 000 extragalactic sky measure distortion galaxies in redshift range $z=0.1$--1.5 resulting from weak gravitational lensing, one two principal cosmology probes leveraged by With photometric redshifts,...
Traditional project design and construction delivery is segmental. Researchers practitioners often cite the separation, or "silo effect," as a reason for poor outcomes. In response, new forms of integrated contracts have emerged, fostering more collaborative efforts focus on successful outcomes, instead individual organizational Relational contract theory provides basis understanding these agreement through set relational contracting norms. This study operationalizes norms designed to...
From the relational contract approaches currently emphasized in construction, researchers have noted that there is enough evidence pointing toward social psychological theories of team formation. Building on a theoretical framework, this paper analyzes social, and formation literature through comprehensive review. Findings reveal construction teams form as small worlds out clusters emerge either contractual, professional, task, or trade relationships, which strongly supports proposed...
Concurrent engineering is the process of reducing total project delivery time by overlapping activities that normally occur sequentially. The benefits are a shortening and possible reduction in overall costs. However, there potential risks to dependent activities. interaction between an upstream activity downstream relies on how information evolves sensitive changing information. This implies if slow evolve highly information, risk these will be higher than fast not as can manifest rework,...
Determining an appropriate delivery method for highway projects is a complex process. This paper presents decision support approach to assist agencies in evaluating and selecting the most suitable their projects. The uses matrix consider three fundamental methods currently use by industry: design–bid–build, design–build, construction manager–general contractor. approach, which Colorado Department of Transportation (DOT), includes four primary selection factors (delivery schedule, complexity...
In highway construction, completing projects on time is critical. However, when are not completed time, one of the aspects that often neglected by state departments transportation (DOTs), which causes delays in project closeout. The closeout phase, if delayed, only has consequences for agencies and contractors, but also leads to substantial social costs public. Despite potential magnitude impact, there limited knowledge about factors cause or strategies timely construction closeouts. This...
The integration of cutting-edge technologies has become prevalent, promoting state departments transportation (DOTs) to progressively adopt an array digital tools and advanced improve their highway construction projects. There is a wide range remote sensing monitoring technologies, including light detection ranging (LIDAR)/3D laser scanning, radio frequency identification (RFID), sensors (RS), infrared (IS), unmanned aerial systems. However, the varying approaches adopted among DOTs can lead...
Economic changes impact the construction industry and associated stakeholders involved in projects. Construction companies are not immune to economic downturns, as evidenced by sharp decline long recovery period with Great Recession of 2007–2009. Therefore, need infuse specific strategies into their business operations. To determine effective for consider weathering risks a Delphi study methodology was employed. Three rounds were conducted qualified financial experts representing officers,...
The use of performance measures for evaluating projects or agencies as a whole is not new idea. Performance have been in many years the private and public highway construction sectors variety areas tasks. American Recovery Reinvestment Act 2009 (ARRA) federal transportation funding are now requiring state to develop document throughout their agency operations. However, few cost estimating. This study synthesizes, categorizes, validates existing estimating assist with improving accuracy. It...
Construction projects primarily use three conventional delivery methods: design-bid-build (DBB), design-build (DB), and construction manager/general contractor (CMGC). Integrated project (IPD) is an emerging method that emphasizes the relational aspect among multiple organizations. It defines success by outcomes of project, not individual organization's outcomes. This a culture change for industry as IPD attempts to assimilate organizations team focus on goals. study examines association...
Methodologies for conducting highway infrastructure inspection activities are experiencing a substantial change with the proliferation of technology. Instead relying on destructive testing methods to perform inspections, state departments transportation (DOTs) use wide range non-destructive (NDT) inspecting construction projects and assets. However, varying approaches adopted among DOTs can lead confusion inconsistency. Therefore, this study aims provide comprehensive systematic overview...
Ensuring the resiliency of a nation's transportation infrastructure network requires skilled and dependable workforce; this relies heavily on agency's ability to recruit retain their employees. Public agencies face unprecedented challenges in preserving workforce necessary function effectively need robust strategies maintain by recruiting retaining quality staff construct now into future. This study identified existing issues recruitment retention practices state Departments Transportation...
Working on construction projects can be complicated and challenging. There are many different entities individuals involved with a project, no two the same matter how similar design may be. Construction engineers today need to able competently communicate, address complexities, team parties that each project possesses. In addition, industry continues evolve advance use of new technologies, materials, practices. For new, inexperienced succeed in industry, they become well-educated core...
Energy usage continues to increase across the globe, which has resulted in increased methods for conserving energy. However, most of these decreasing energy consumption focus on political and economic policies, as well curtailing by promoting individual energy-efficient products practices such appliances, electronics, improved building envelope maintenance. To determine better policies conserve energy, habits perceptions need be considered. One consideration is a household's perception...
With the infusion of emerging technologies into highway construction practices, state departments transportation (DOTs) can make better informed decisions that positively influence cost, schedule, quality, and safety. DOTs are increasingly using instrumentation sensor for delivering projects across U.S.A. Instrumentation devices sensors include such as remote sensing, real-time kinematics, global positioning systems, digital handheld devices, ground penetrating radar, intelligent...
Project team integration is attracting interest in public projects due to the increasing success and popularity it has private sector of construction industry. Public transportation must follow state federal regulations for method procurement delivery a project. Many traditional methods invoke more competition rather than cooperation resulting adversarial relationships as oppose integrated teams. Team incorporates differentiable goals between major project participants into cohesive...
