Delay is one of the greatest challenges facing the implementation of construction projects. The completion project time is considered one of the measure indicators for assessing the success of any project. Delays usually have negative impacts of financial and social to all parties involved in the projects. The aim of the study is to find the most important causes of delay by evaluating the common causes of delays in terms of frequency, severity, and important indices in implementation of public construction projects in Erbil Governorate related to owners, contractors, consultants, and external factors. The data gathered through conducting a questionnaire for perception various parties involved in implementation of public construction projects. For these purpose, 104 forms of questionnaire were distributed to various parts to identify the delay causes in accordance with their opinions. It was concluded that the most significant factors causing the delay in construction of public project in Erbil Governorate related to the owner were “variation orders by owner during the construction” which came in the first rank, while the cause of delay related to the consultant that came in the first rank was “unclear and inadequate details in drawings,” whereas the factor related to the contractor which came in the first rank was “selecting incompetent contractor.”

Causes Of Delays

Variation order plays an important role in calculating the final cost and time. The paper aims to determine the causes of variation orders in projects performed between 2007-2014 in Erbil governorate projects. Data was collected from contract documents. Performed in the Erbil governorate projects from 2007-2014. The study seeks to identify the most significant causes of delays by assessing the common causes of delays in terms of frequency, severity and  important indices of owners, consultants and contractors related to the implementation of public construction projects in Erbil Governorate. The data acquired from the questionnaire given to the engineers involved in executing of these projects and 73 forms were returned. The results showed that the ranking of overall causes of variation order from highest  to lowest was  "Contractor's financial difficulties", " Change of plans or scope by owner", "The required labor skill are not available", "Differing site conditions", "Owner's financial problems", "Design change originated by owner", "Errors and omissions in design", " The required equipment and tools are not available", Inadequate working drawing details",  and " Change in design by the engineer or consultant". The source of   "Errors and omissions in design", "Inadequate working drawing details”, and Change in design by the engineer or consultant" is consultant.

The Comparative Study

Purpose One of the solutions to manage large public projects that are complex and difficult to manage is through relationship management. Although formal and relational approaches have been adopted in managing relationships, it is widely recognized that participants from developed and developing economies have different mindsets toward these two approaches. The purpose of this paper is hence to elucidate the more effective practices for managers to manage relationships in large public projects that are in countries of different sizes and stages of development. Design/methodology/approach A structured questionnaire survey was conducted. Multiple stakeholders involved in public construction projects in Singapore and China that include public sector clients and consultants, private sector contractors and conszultants, were approached for data collection to provide information on one of their completed large public project. Findings Both Singapore and China primarily adopt contractual governance by making rational decisions, pursuing profit and using the contract to guard against trouble. Participants in Singapore are more deeply committed and work more collaboratively than their counterparts in China. Project partners in China build stronger relationships, which may be due to the importance of “guanxi” to conduct business activities there. Originality/value The comparative study provides managers with different sets of governance practices to adopt to improve the relationships with public clients in large public projects under different environments. In large public projects in developed countries, participants should rely more on relational practices that show commitment and teamwork, while those in developing countries participate in activities that build up their social networks.

There has been a persistent reported increase in project failure in many Iraqi’s construction public project. This has resulted in project withdrawal from contractors, and revoking of companies licenses due to weak performance. This study investigated the effect of strategic and employee factors on the performance of construction public projects in Iraqi. The findings indicated that strategic and employee factors were statistically significant and they are important determinants for performance measurement. On the overall, the employee factors are more important than strategic factors and its component rewards is the most important variables. There is therefore a need for policy makers in Iraqi to focus on strengthening the role of strategic and employee factors in enhancing the project performance in construction projects.

Quality Assurance Scheme

Scope management in the form of reduction lists was integrated in the quality assurance scheme for Norwegian public projects in 2001. This article presents findings on the actual use of reduction lists for major public construction projects Project representatives were contacted to obtain information about the actual use of pre-defined potential scope reductions. Eight of the 14 studied projects did not implement any of the predefined reductions. Six projects implemented some of the reductions. The scope reductions on the reduction lists are very specific and detailed, unlike general theory on scope management and cost control. However, the findings from the study are in line with the general theory; it was the most general scope and cost reductions that where used in practice. The study subsequently looked into the relationship between scope reductions and sustainability. Although the most frequently observed reduction was of the category “reduced quality or functionality”, sustainability was rarely affected with the notable exception of the railway infrastructure projects.

<p>In Taiwan, the regional drainage is the system of two or more of urban, agricultural and enterprise drainages. Communities locate in or around the urban river, farmland or estuary are significantly involved in four services of ecosystem services. From 2016, central government forced each public construction project has to implement ecologic check work. However, these check work did not yet follow the idea of ecosystem services so that the operation of public construction projects in these two years could not reach the target completely. This study introduces the idea of ecosystem services into the ecologic check work of regional drainage projects to explore the feasibility of selected parameters in ecosystem services.          </p><p>This study refers to ecosystem service strategies such as the Millennium Ecosystem Assessment (MEA, 2005), the Economics of Ecosystems and Biodiversity (TEEB, 2010) and the Common International Classification of Ecosystem Services (CICES, 2017), considering the extensiveness, feasibility, and regional characteristics of regional drainage for ecosystem services. In addition, this study designs two checklist forms for master plan and project, respectively. After implementing ecologic check work for three cases in Taiwan, the result explores the feasibility of ecosystem services in regional drainage system.   </p>

Purpose The dynamics and effects of interconnected risks among construction organisations tend to be overlooked across the Malaysian public project supply chains, making them highly vulnerable to supply chain disruptions. This study aims to investigate this dynamism by assessing the supply chain’s critical vulnerabilities and capabilities that formulate the level of resilience in handling disruptive events in construction projects. Design/methodology/approach A comprehensive questionnaire survey was conducted with 105 construction professionals from two groups of respondents, the public and private organisations that work in public projects to identify their current vulnerabilities and capabilities. Data were analysed and compared using the Mann–Whitney U and Kruskal–Wallis tests. Findings The findings revealed that the top five critical vulnerability factors of the supply chain include political or regulatory changes, market pressures, management, financial and strategic vulnerability. Further comparisons highlighted that the public organisations faced significantly higher political threats compared to the private organisations whilst the private organisations faced significant market pressures. The survey also shows that despite the private organisations’ high capability in financial strength, the public organisations’ financial vulnerability has destabilised the entire supply chain. Originality/value This study presents the construction supply chain’s vulnerabilities in a layered framework approach that can provide managers a new perspective on the dynamics of the cascading impacts of these vulnerabilities when observed through several layers of supply chains.

Level 2

Building Information Modelling (BIM) is a technology and process that are transforming way of designing, constructing, operating and using the building or facility. In essence, BIM models is a platform for collaboration as it encourages intensive communication and interdependence among multidisciplinary project members. In Malaysia’s BIM Guide, this collaborative process can be seen in Level 2 BIM Maturity which all designers engaged in projects work together to create a single computer-generated 3D Model. From this process, many benefits that BIM promises such as clash free construction, quality of design and greater certainty could be achieved. Therefore, the Malaysian Government announced the implementation of at least 40% of Level 2 BIM for public projects costing RM100 million and above in 2019. However, despite mutual understanding between construction players, the full integration of BIM in the project lifecycle seems to be a daunting task. In the context of the Malaysian Public Sector, many uncertainties could arise pertaining to legal and contractual matters i.e. whether or not the existing contractual instruments are able to support the collaborative environment and digital information sharing that Level 2 BIM engenders. This paper presents a narrative review of published literature on the concept of Level 2 BIM and contractual consideration based on the utilisation of BIM within Malaysian Public construction projects, which includes books, government publications, conference presentation slides, newspaper articles and paper-based journal articles. This paper concludes that in order to legitimise multidisciplinary collaboration and integration of information in BIM within existing standard forms of contract, the development of a contract protocol and suitable procurement model are necessary.

The construction industry is a competitive high-risk industry with an unprecedented uncertainties in technology, budget, and development processes. It has become more dynamic in nature and the execution of projects have become more complex and difficult to manage. The need then evolved to develop a framework for project performance. This study investigates the factors affecting the project success and performance using a knowledge and resource-based approach. Data was collected from project managers, civil engineers, site managers, and architects. A total of 221 responses were collected. The data analysis was conducted using SPSS and Smart PLS. This results from this investigation revealed that knowledge transfer does not mediate the effect of strategic factors or employee factors on the project performance of Iraqi public construction projects. This finding indicated that the role of knowledge practices in Iraqi public project is still not matured. Top management are advised to effectively implement the knowledge management practices in public projects. Implementing knowledge management will avoid the organization the cost of repeating the same mistakes. Thus, it was concluded in this study that knowledge transfer is still in its infancy and currently it has no mediating effect between the variables of this study.

Saudi Arabia has been facing issues with completing construction projects on time and on budget. It has been documented that 70% of public construction projects are delayed. A case study was performed, at a University campus in northern Saudi Arabia, identifying the major causes of project delays. The University was experiencing delays from 50% to 150%. The delay factors were gathered from the University Projects Director and five engineers. The University delay factors were then compared to delay factors experienced on Saudi construction projects, identified by performing a literature research. The comparison identified nine causes of delays that both studies documented. The study also proposes a solution to minimize the nine major delay factors. A literature research identified one construction management method, the Performance Information Procurement System (PIPS), has documented multiple times its ability to improve project performance and minimize delays.

Purpose The high rate of rework that occurs in construction projects has a negative effect on the performance of the construction projects. Although several mechanisms have been implemented to control reworking, a comprehensive list of rework causes is yet to be provided to present the common causes that contribute to rework in construction contracts. This paper aims to investigate the most common rework causes that need to be addressed in construction contracts. Design/methodology/approach A mixed-method using both the qualitative and quantitative approach is used in this paper. First of all, the study adopted a four-step literature review to introduce the rework research trends and provide statistical reports using descriptive analysis. Next, a comprehensive review has been completed using content analysis to identify the common causes of rework in construction projects. Finally, the common causes in construction contracts are further investigated through a quantitative questionnaire survey to validate the initial results. Findings The results of the review showed an increasing trend of publications on rework over the last three decades. Most of the studies were conducted in Australia, the UK, Nigeria and Hong Kong. Based on further investigation in the study area of sources of rework, 37 causes of rework causes were identified and classified in five groups. Then, the most significant causes of rework in construction contracts were compiled in the list of 22 items. Research limitations/implications The paper’s reported result, contributes to the contract management body of knowledge by proposing a list of common rework causes that can be used by practitioners during the contract negotiation to prevent contractual issues. The result of the review can also be used for further investigation of the relationship between rework and contract conditions. Originality/value The proposed list of common causes of rework in construction contracts allows project parties to improve the terms of the contract in addressing rework, this could result in fewer contractual claims and disputes. The findings of this study will also guide the investigations into the contract conditions, thus the approach used is constructive.
