The Impact

Abstract Road construction projects are characterized by multitasking and the influence of the correct implementation of one task on another. In the subject literature, we can encounter the analysis of risk factors throughout the project, and yet, we rarely find the distinction and characteristics of the impact of risk factors resulting from the implementation of planning and measurement tasks, the correctness and timeliness that have a huge impact on the performance of subsequent tasks, and the success of the project. Additionally, attention should be paid on the distinction between design work and the implementation of construction. During the implementation of construction works, we are more capable of detecting errors faster at the initial stage than at the stage of performing measurements, which suggests the need to focus on minimizing the occurrence of risk factors at the initial stage. Therefore, two questions have been asked. How to quantify the risk factors of geodetic works in road construction projects? How to allocate quantified risk factors of geodetic works in the schedule? The following article presents the description and the example of the practical use of the risk assessment procedure of geodetic works and risk allocation in the schedule based on the MORAG method (Method of Risk Analysis for Geodesy), which is the original method of risk analysis of geodetic works in road construction projects. As a result of these works, the risk values for the i-th risk factor and i-th geodetic task were determined, considering the increase in the duration of the work, the increase in the costs of the work, and all evaluation criteria. Then, the extension was described and calculated based on the data obtained from the actual implementation of the road construction project, the value, which in this case is 11.05 days, was entered into the modified schedule. The results of this study may help to better understand the scale of the impact of the correctness of the implementation of geodesy tasks on the implementation of construction tasks. Additionally, they may serve to increase the awareness of the scale of consequences of incorrectly performed measurement tasks (demolition is necessary) and greater attention on the cooperation between the entities implementing these activities.

The article is a continuation of the series of works on the method for risk analysis in surveying works in road construction projects. The paper presents the application of fuzzy logic to determine the nature and value of the risk of surveying works based on a database of rules and affiliation functions provided by experts. The fact that the issue of occurrence of risk factors in road construction works is not deterministic justifies the above. In such works, there are many uncertainties in establishing the value of their duration in the long term. The theoretical framework of the method is presented together with an example of its application. Moreover, research results are compared with previous publications using other research tools.

The Impact

The coastline of Western Pomerania has natural and cultural assets that have promoted the development of tourism, but also require additional measures to ensure the traditional features and characteristics are protected. This is to ensure that new developments conform to a more uniform set of spatial structures which are in line with the original culture. Today, seaside resorts are characterized by a rapid increase in development with a clear trend towards non-physiognomic architectural forms which continually expand and encroach on land closer to the coastline. This results in a blurring of the original concepts that characterized the founding seaside resort. This study evaluates 11 development projects (including a range of hotels, luxury residential buildings and hotel suites) built in 2009–2020 in the coastal area of Western Pomerania. An assessment of architecture-and-landscape integration for each development project was made, using four groups of evaluation criteria: aesthetic, socio-cultural, functional and locational factors. The study methodology included a historical and interpretative study (iconology, iconography, historiography) and an examination of architecture-and-landscape integration using a pre-prepared evaluation form. Each criterion was first assessed using both field surveys and desk research (including the analysis of construction plans and developer materials), and then compared with the original, traditional qualities of the town. This study demonstrates that it is possible to clearly identify the potential negative impact of tourism development on the cultural landscape of seaside resorts, and provides recommendations for future shaping, management and conservation of the landscape.

Construction projects in Iraq face many dangers that cause exceeding the estimated cost of the project and not completing the project on time, and since the risk management process in construction projects is of great importance in controlling and reducing the impact of risks in construction projects, so it is necessary to identify these risks and evaluate them correctly in order to increase accuracy and the health of the subsequent stages of the risk management process in construction projects. This paper aims to identify the most important risks in construction projects in Iraq and to conduct a qualitative assessment of the identified risks and arrange them according to their importance. The researcher adopted the questionnaire method as a tool to determine the risks and used the technique of probability and effect matrix to conduct the qualitative assessment of the identified risks. The study found that there are 48 risk factors that constitute the most dangerous factor in construction projects in Iraq, and 10 of the determining factors were within the high level of risk, and at the forefront of which was the inability of the owner to finance the project.

Purpose This paper aims to enlighten the importance of the risk management process which is considered as a major procedure to effectively handle the potential inherent risks in the construction industry. However, most traditional risk analysis techniques are based on theories that deal with each risk factor as an independent, which does not take into consideration the causal relationships between risk factors. Design/methodology/approach This study aspires to identify the overall risk of the administrative construction projects in Egypt and to recognize the most influencing risk factors through the project life cycle by using Bayesian belief networks (BBN). Through a review of the literature, 27 risk factors were identified and categorized as the most common risk factors in the construction industry. A structured questionnaire was performed to estimate the probability and severity of these risks. Through site visits and interviews with experts in the construction field, 200 valid questionnaires were collected. A risk analysis model was developed using BBNs, then the applicability of this model was verified using a case study in Egypt. Findings However, the outcome showed that critical risks that manipulate administrative construction projects in Egypt were corruption and bribery, contractor financial difficulties, force majeure, damage to the structure and defective material installation. Practical implications The proposed study presents the possibilities available to the project parties to obtain a better forecast of the project objectives, including the project duration, total project cost and the target quality by examining the causal relationships between project risks and project objectives. Originality/value This study aspires to identify the overall risk of the administrative construction projects in Egypt and to recognize the most influencing risk factors through the project life cycle by using BBNs.

The Impact

Purpose – The allocation of risk among project participants is an important determinant of innovation success in construction projects. The purpose of this paper is to examine the capacity of risk allocation to encourage the implementation of environmental innovation, particularly sustainable energy innovation (SEI), within the private finance initiative (PFI) project delivery model. Design/methodology/approach – A four-case qualitative research methodology is adopted within the context of the UK government’s building schools for the future programme. Findings – The findings identify that SEIs are encouraged on the innovative projects by the perceived clarity, appropriateness, and manageability of the risks associated with the project’s energy performance on the PFI contract. The main SEIs were largely developed as strategies to manage long-term energy performance risks allocated to private sector actors and safeguard their long-term commitment to the project. However, the findings indicate that excessive perceived innovation-related risks, particularly capital cost risk, may restrict further SEIs to be implemented. Research limitations/implications – The qualitative case study approach adopted may limit the generalisability of the findings. Practical implications – The study and provides practical guidance to policymakers and project managers in developing strategies to support the implementation of SEI in PFI projects. Originality/value – The study attends to a significant gap in knowledge as there is a lack of conceptual and empirical work on managing innovative processes for sustainable energy in PFI projects.

The aim of the paper is to research and analyze the impact of the type of failure on economic risks in the bidding phase, as the most important part in the management of construction projects. The survey included the impact of risk on the process of determining unit prices from the perspective of a potential contractor. Also, the failure rate and repair rate of the 34 machines from the machine park of the company for road construction were researched. On the basis of obtained parameters and depreciation periods, the operational availability of components of construction production systems was determined. The proposed methodology for estimating impact of the availability function is a modified method of the frequency balancing. It has been tested on a concrete project from the practice in the process of harmonizing construction norms of time that preceded the final adoption of the unit prices. Differences in prices are results of the system failure of construction machinery and plants and have justified a hypothesis of obtaining more realistic costs that can occur in the projects.

Cost Of Construction

Construction projects are prone to a number of risks due to their complexity, dynamic nature, capital intensive nature and involvement of many stakeholders. These risks if left unmanaged will negatively influence the completion cost and other primary objectives of construction projects. Numerous studies have been conducted globally to determine the potential risks that negatively impacts construction projects; however, the risks aren’t alike across all the regions and the potential degree of impact may changes with time. This study assessed the impact of risk factors on completion cost of construction projects in Nigeria. Data was collected using structured questionnaires administered to 192 construction practitioners using convenience sampling technique. Descriptive statistics (mean and standard deviation) were used to analyse the data. The study found ‘inadequate cost estimate’ (MS = 4.39), ‘risk incurred due to bribery and corruption’ (4.30), ‘increase in prices of materials’ (4.25), ‘increase in cost of labour’’ (4.11), ‘poor cash flow management’ (4.04) ‘mistakes/errors in design’ (4.04) and ‘mistakes during construction’ to be the topmost risk factors that impact on project completion cost. The study concludes that ‘economic’, ‘financial’ and ‘contract administration and project management’ related factors group are those with high impact on project completion cost.
