Construction projects are usually associated with several challenges owing to the varying process during the project lifetime. Hence, the final cost of any civil engineering project is influenced by many factors. There are numerous ways of determining the final cost of a project, however, the most essential approach is the Estimate at Completion (EAC) technique. This technique is mostly favored because it considers the probability of risks and project performance. Furthermore, EAC helps project managers in the definition and determination of the critical problems expected during the project period and the likely solutions toward these problems. In this review research, the basic empirical, regression and advanced soft computing methodologies adopted for the EAC computation, were surveyed and reported in detail. The review established on the base to recognize the modern advancement of the soft computing in computing the EAC with accurate, reliable and robust manner. The review was highlighted the main literature limitation, current status and possible future direction.

Purpose – Rework is an endemic problem in construction projects and has been identified as being a significant factor contributing cost and schedule overruns. Causal ascription is necessary to obtain knowledge about the underlying nature of rework so that appropriate prevention mechanisms can be put in place. The paper aims to discuss these issues. Design/methodology/approach – Using a supervised questionnaire survey and case-study interviews, data from 112 building and engineering projects about the sources and causes of rework in projects were obtained. A multivariate exploration was conducted to examine the underlying relationships between rework variables. Findings – The analysis revealed that there was a significant difference between rework causes for building and civil engineering projects. The set of associations explored in the analyses will be useful to develop a generic causal model to examine the quantitative impact of rework on project performance so that appropriate prevention strategies can be identified and developed. Research limitations/implications – The limitations include: small data set (112 projects), which include 75 from building and 37 from civil engineering projects. Practical implications – Meaningful insights into the rework occurrences in construction projects will pave pathways for rational mitigation and effective management measures. Originality/value – To date there has been limited empirical research that has sought to determine the causal ascription of rework, particularly in Hong Kong.

The continuous economic and social progress of our country has helped the rapid progress of civil engineering projects. However, the relatively improved civil engineering project creation also has many shortcomings, such as waste of resources, depletion, and pollution of the natural environment. The construction project itself is an item. The energy consumption is relatively high. Due to the shortage of resources and the more serious natural environment and ecological problems, the public pays more attention to the related problems of their own quality of life, and more and more people are adopting green building materials. Therefore, it is very important to explore the application of green building materials in civil engineering projects.

Significant Factors

Civil engineering projects trigger the economic growth by providing infrastructure facilities and job opportunities as well as attracting the attention of foreign investments. Due to their significant contributions toward the nation growth, the performance of civil engineering projects has become the upmost concern by the government. Unfortunately, many civil engineering projects in Malaysia are dominantly associated with unsatisfactory performance in terms of cost, time and quality of the delivered products. Therefore, this paper aims to identify the underlying causes which lead to unsatisfactory performance by determining the factors affecting civil engineering projects. The objective of this paper is to identify the civil engineering project characteristics and the quality of Standard Form of Contract (SFoC) adopted and the contractual behaviour of key participants of civil engineering project which affecting the performance. Questionnaires survey were conducted to undertake the research. 124 feedbacks received out of 300 questionnaires distributed to the G7 contractors registered under Construction Industry Development Board (CIDB) and consultant engineer registered under Board of Engineers Malaysia (BEM). The data was statistically analysed using SPSS 21 and descriptive analysis was used for rank assessment of factors. It was found that the top three (3) most significant factors affecting civil engineering project performance are delay in making payment, environment uncertainty and the clarity of SFoC. These factors belong to three categories i.e the contractual behaviour of key participants, project characteristics and the quality of SFoC category. Thus, these categories are paramount to be put more concern on the performance of civil engineering projects in Malaysia.

Engineering projects often face a great number of uncertainties which will lead projects to deviate from the anticipated objective. This paper carried out a detailed study on real-time monitoring of objective deviation in engineering projects, and it will help project managers monitor the state of engineering project better. A Grid Management (GM) method was used to set up a monitor structure, and the real-time monitor grid structure was constructed in level, milestone and objective dimensions. The buffer analysis method was designed to measure the level of objective deviation. The objective deviation level is based on the result of the grid cell buffer analysis. The principal part construction of Shenyang Olympic Tennis court was selected as the example to illustrate the real-time monitor process in detail. The results indicated that the proposed real-time objective monitor method makes it possible for project manager to real-time monitor all the main objectives in one model and carry out management, and decision-making in a more macro perspective.

Soil bioengineering includes the sustainable use of vegetation for civil engineering purposes, including addressing climate change challenges. Previous research in this area has been focused on determination of the strength and stability that vegetation provides for the soil it grows in. The industry, on the other hand, has concentrated on mainly empirical approaches in the design and construction of nature-based solutions. The aim of this paper is to attempt a reconciliation of the scientific and technical aspects of soil bioengineering with a view of proposing broad guidelines for management of soil bioengineering projects aimed at combatting climate change and achievement of the United Nations Sustainable Development Goals (UN SDGs). More than 20 case studies of civil engineering projects addressing climate change challenges, such as erosion, shallow landslides, and flooding, were critically reviewed against the different project stages and the UN SDGs. The gaps identified in the review are addressed from civil engineering and asset management perspectives, with a view of implementing the scientific and technical nexus in the future. Recommendations are formulated to help civil engineers embrace the multidisciplinary nature of soil bioengineering and effectively address climate change challenges in the future.

Works, constructions, and fabrications are examples of projects that in themselves are complex, especially for inexperienced project managers or other areas. The complexity classification of engineering projects is important to determine the necessary efforts for the management of this enterprise and also to analyze threats and opportunities. This chapter looks at how this categorization is done and the best practices in engineering and construction projects. At the end, it presents a proposal to classify the complexity of enterprises in energy, civil construction, mining, and other related business sectors. This is a conceptual and applied reading in engineering and construction projects.
