Failure Factors

A poorly coordinated performance among stakeholders in the finishing phase can impair the performance of a high-rise building project. Therefore, it is necessary to analyze construction failure factors (CFFs) to stakeholder coordinating performance (SCP) in the finishing phase of high-rise building projects and to uncover their underlying relationships. CFFs to SCP in construction projects, especially in the finishing phase of high-rise building projects, have not yet been discovered. The study identified 30 CFFs to the SCP and ranked them according to the perspective of the stakeholders, including owners/consultants and contractors/subcontractors. Additionally, four factors of the CFFs, namely, traditional adversarial relationship, poor project planning and organization, incompetent parties, and delays of parties toward construction works were extracted by the factor analysis method. This study fills the gap in knowledge related to the coordination performance in construction projects. The findings could help stakeholders to enhance their coordinating performance in high-rise building projects.

Abstract. Aim. The aim of the study is to develop an environmental passport based on the structure of integrated environmental safety for construction projects. With each year that passes, environmental problems are coming increasingly to the fore. As part of mitigation efforts, an environmental passport is required to assess and control the environmental safety of construction areas and building sites.Method. The study is based on the development of a sound model of integrated environmental safety in construction projects and a methodology for calculating its indicators, in particular, the indicator of “degree of concentration”. The methodology of ranking the factors by importance is applied.Results. The structure of a building site's environmental passport is presented, taking the entire spectrum of its direct impact and environmental pollution into account, as well as the indirect impact, energy efficiency and autonomy of the site. The scope of the environmental passport comprises the entire building lifecycle, from design to operation and liquidation. An environmental passport en-ables the identification of problematic impacts on the geophraphical area from an environmental point of view, as well as giving recommendations for resolving problems. The threshold of environ-mental safety is set for each geographical area under assessment (i.e., for each building project and geographical area, it is determined by the composition of relevant factors) and the existing level of environmental pollution is determined along with the ecological reserve of the area and its steady state range, i.e., the acceptable level of deviation of environmental safety indicators, which depends on temporary factors and the objective reality of the functioning of the infrastructure of the evaluated territory. For the design and construction of building projects, indicators of environmental reserve and technogenic pressure of the facility are of fundamental importance when making decisions.Conclusion. The article presents a rational assessment of the main indicators of the environmental pass-port, providing the structure of a comprehensive assessment of environmental safety. The research results are presented and the scope of the environmental passport proposed in the assessment of geo-graphical areas and evaluation of facilities and design.

The delay of vast building projects is still a common problem. This situation is extraordinarily severe to steel reinforced concrete (SRC) building projects that keep going to promote a new structure system in Taiwan's construction industry. The aim of this study is to develop a feasible contract duration model based upon few SRC building cases. A logical approach is employed to select and assure the “good” regression model identified when project characteristics were known and external uncertainties were reasonably estimated. Different necessary diagnostics had been adopted to examine the aptness of the model before inference. The cross-validation is used to validate the appropriateness of the variables selected and magnitudes of the regression coefficients. The mean of the square prediction errors (MSPR) is selected to measure the predictive ability of the model proposed, and the result shows that the predictive ability of the selected regression model could be adequate. Finally, several cases are taken to test the predictive accuracy of the model proposed, and the result shows that the actually necessary construction duration is considerably closed to the duration predicted by the mode. It is concluded that the predictive duration model proposed could be applicable to the SRC construction projects with a reasonable reliability. Santrauka Vėlavimas realizuojant stambius statybų projektus tebėra dažna problema. Ši situacija ypač rimta dirbant su gelžbetoninių statybų projektais, kuriais populiarinama naujų konstrukcijų sistema Taivanio statybų sektoriuje. Šiuo tyrimu siekiama sukurti tinkamą sutarties trukmės modelį, pagrįstą keliais gelžbetoninės statybos atvejais. Atrenkant ir užtikrinant, kad būtų sudarytas ,,geras“ regresijos modelis, kai projekto savybės žinomos, o išoriniai neapibrėžtumai pakankamai įvertinti, taikytas loginis metodas. Prieš darant išvadas modelio tinkamumas buvo išnagrinėtas naudojant skirtingas būtinos diagnostikos priemones. Naudojant kryžminį patikrinimą pagrindžiamas pasirinktų kintamujų tinkamumas ir regresijos koeficientų vertės. Siekiant įvertinti siūlomo modelio tinkamumą prognozuoti, apskaičiuotos vidutinės kvadratinės prognozavimo paklaidos (angl. Mean of the Square Prediction Errors, MSPR). Rezultatas rodo, kad pasirinktasis regresijos modelis prognozuoja gana gerai. Pagaliau pasirinkus kelis atvejus išbandomas siūlomo modelio prognozių tikslumas. Rezultatas rodo, kad faktinė bū tina statybų trukmė gana artima modelio prognozuojamai trukmei. Daroma išvada, kad siūlomą trukmės prognozių modelį galima taikyti gelžbetoninės statybos projektuose, o jo rezultatai bus gana patikimi.

Adaptive reuse of buildings is considered a superior alternative for new construction in terms of sustainability and a disruptive practice in the current capital project delivery model for the renewal of today’s built environment. In comparison to green-field construction projects, adaptive reuse projects require distinct stages, definition of interfaces, decision gates, and planning methods in order to secure the success of the building project. Unfortunately, little research has been done regarding establishing feasible systems for the planning, assessment, and management of adaptive reuse projects, leading to underperforming building projects outcomes. Interface management (IM) can improve renovation projects outcomes by defining appropriate ways to identify, record, monitor, and track project interfaces. IM has the potential of bringing cost and time benefits during adaptive reuse projects execution. The aim of this study is to develop a reference framework for implementing IM for adaptive reuse projects. First, the inefficiencies of redevelopment projects are explained inside of a circular economy (CE) context. Second, an ontology of IM for adaptive reuse projects is defined based on the current barriers to adaptive reuse and the most common interface problems in construction projects. Third, the defined ontology is expanded through a case study by showing examples of adaptive reuse barriers on a case project, and how IM could have been part of the solution for these problems. Finally, this study concludes with the suggestions on interface management systems (IMS) implementation for future adaptive reuse projects.

Construction projects usually encompass numerous disciplines, requiring the integration of knowledge from civil, mechanical, electrical and other engineering domains. Some researchers contend that the integration of construction knowledge and experience at the early design phase would improve the overall project performance. Domination of tacit knowledge during design phase of building projects is the major source of knowledge flow problems between involved professionals. Therefore, this study intends to explicate the required mechanical and electrical knowledge which has to be considered during the conceptual design phase of a green building project. To fulfil this goal, a case study has been conducted to specify the entity of the required mechanical and electrical knowledge. The primary method for the data collection here is observation. Furthermore, this study employs the triangulation method in order to validate the collected data. The results contain the required mechanical and electrical knowledge which has to be considered during the conceptual design phase of a green building project.

Achieving and maintaining quality values are indispensable for attaining organizational and customer satisfaction. This research investigates different aspects of operationalize quality culture and factors affecting the quality of building construction in under developed countries like Pakistan. A qualitative and quantitative survey was circulated among different stakeholders including Clients, Consultants and Contractors to assess the level of the contractor’s performance, the project monitoring and controlling techniques, proper health and safety requirements, client satisfaction and workers experience in construction industry projects. The practice of professional quality management in building projects is increasing, however, many flaws and negligence are still found in local practices. This analysis also indicates that political and socio-economic factors play a significant role in maintaining the quality level in local industry. Therefore, the allocation of sufficient resources, proper training of workers, and recruitment of quality control staff and the use of advanced technologies are recommended for proper implementation of QMS (Quality Management System).

The most controversial trouble that happened in the construction projects is Delay. So, the specified research took part to investigate the basic causes in delaying the Kurdistan Region of Iraq. The study gathered information from the insight of contractors, consultants, and owners. A wide literature review has been discussed. The delay causes are recognized built on the identified literature review. These features are characterized into owner-related, consultant-related, contractor-related, material-related, labour and equipment-related, and external-related groups. Twenty- six experienced persons participated in doing the questionnaire surveys to control the relative importance of every cause. The work discovered that the highest five reasons for postponement in building projects are financial difficulties by contractors, variation in prices, postponement in making and appreciative shop diagrams, lack of labour, and mistakes in soil study. Lastly, the probable approaches of dropping plan postponements are suggested. This work helps as a helpful tool for construction experts and academics to prevent reasons for postponement in constructing schemes in Kurdistan.

The Impact

There have been many studies done on the causes of delay on construction projects and building projects all around the world. They use different methods, on different geographical areas, and they come up with different results. There are, however, few studies on industrial and building projects. This paper focuses on industrial/manufacturing projects in Saudi Arabia. The aim of this paper is to identify the major causes of delay in the manufacturing projects in Saudi Arabia. The top causes of delay have been identified through a literature survey and interviews with experts from the industrial field in Saudi Arabia. Twenty-two factors have been identified and listed in a survey that was distributed to professionals in the same field. Two categorizations were made: the first is based on the impact of the cause, and the second is based on the frequency of occurrence of the identified cause. It has been found that the top five impacted causes of delay in the delivery of industrial projects in Saudi Arabia are: difficulties in financing project by contractor/manufacturer, late procurement of materials, late delivery of materials, delay in progress payments, and delay in approving design documents, respectively. In terms of frequency, the top five identified causes are: delay in progress payments, difficulties in financing project by contractor/manufacturer, slowness in decision making, late procurement of materials, and delay in approving design documents, respectively. The diversity of the participants is an important point; therefore, the respondents were from different job positions (management, engineering, etc.), and different categories (contractor, owner, manufacturer, consultant, etc.). It is worth noting that this paper serves not only as an authentic study of the causes of delay in the delivery of industrial projects in Saudi Arabia which is a field that is not widely covered, but also as a fresh paper that gives an indication of the changes that happen to the business over time as compared to previous work.
