Any construction project, even one that is excellently planned and organized, is prone to the risk of unforeseen events and problems, which in effect can cause late completion of works. The paper presents the results of the research conducted among Polish and Slovakian building contractors. One attempt was to identify and assess the potential causes of delays in the construction works resulting from the provisions of the contract. The knowledge of these factors can help contractors to take protective measures, reducing the risk of delays during the implementation of construction works.

The construction industry is sensitive to changing random conditions that determine the occurrence of various disturbances during the construction investment process. These disturbances are the source of numerous delays during realization of the construction project. The identification of the reasons for delays and their impact on the progress of construction works allows for the efficient management of the construction project and planning of protective measures, which reduce the risk of their occurrence. The purpose of this article is to identify and then to assess, on the basis of the conducted questionnaire survey, the impact of disturbances on delays in construction works. In addition, the factors were ranked in terms of the degree of impact on the construction project by calculating the rank of the factor.

The article presents the results of nationwide surveys on the causes of delays during the implementation of rail investments in Poland, carried out in the Design & Build formula for the design stage. The study did not examine typical causes of threats to general construction works, only those that result from the specifics of works at rail facilities. The survey was conducted with the participation of experts from various industries, representing all the key participants in the investment process. The selection of experts was limited to people who have extensive professional experience in implementing rail projects. Statistical analyzes were performed using the IBM SPSS Statistics 23 package. It was used to test χ2 and a one-way repeated measures ANOVA. The greatest threats to the deadlines for the implementation of rail investments in Poland, which were indicated by the respondents as the delay threats of a high importance are: negligence in the preparation of tender documents and problems with obtaining current maps for project purposes from rail geodesic centers. The research results can be helpful when planning future rail investments, calculating the necessary time reserves and increasing the reliability of the set dates of their completion.

ABSTRACT The Calaveras Dam Replacement Project, a major construction project completed in 2019, involved hundreds of workers using heavy earth-moving equipment and mining operations, including blasting, drilling, rock crushing, and other operations designed to move millions of cubic yards of earth. Much of the material was composed of serpentinite, blueschist, and other rocks that contain chrysotile and a variety of amphibole minerals, including glaucophane, winchite, actinolite, tremolite, and other asbestos-related amphiboles. This article explores the unique characteristics of the blueschist that required extensive protective measures to be undertaken by the contractor to protect workers and surrounding sensitive receptors. This article will provide an overall summary of the dimensional characteristics of the airborne blueschist elongate mineral particles encountered during construction activities to compare and contrast current understanding of cleavage fragments versus asbestiform mineral fibers.

Augmented reality is one of the innovative technologies that will provide significant benefits to construction project applications in the future. In this study, an augmented reality system is developed for improving construction project activities. By using this system, construction workers, equipment operators, engineers and managers can follow each step of the construction activities that they are responsible for. Users can access necessary information about training materials and construction methods related to the construction works. Thus, construction engineers and workers can learn the correct methods of project activities and prevent themselves to make wrong productions. The system is tested in ceramic tile installation. It has been proposed that the system can improve the quality and productivity of construction activities and therefore provide significant contributions to the construction industry.

Contractors are one of the important parties in completing a construction project as they directly involved in the construction works execution. Therefore, contractors’ performance should be monitored and assessed on a regular basis to ensure the success of the project, particularly by identifying the failures and shortfalls, as well as any delays and losses that might occur due to the poor productivity of the contractors. A systematic performance appraisal is one of the endeavours in ensuring that the contractors’ performance is as per the expectation of the stakeholders, particularly the client. Hence, this paper provides a review on the contractors’ performance appraisal practices in construction industry in Malaysia. Questionnaire survey on 214 respondents from construction industries, ranging from contractors to project managers, was undertaken where the results showed that contractors’ performance appraisal in a particular construction project is very essential as it drives the project towards better improvement and ultimate success.

Currently, many road projects are performing poorly for timely completion, an analysis of time road project implementation needs to be done on the contractor company, so that it can be known that the shortcomings and weaknesses done so far, which later can be an input for contractor, to be even better in the implementation of time management of a road construction project. In 2017 many packages of road construction works in Sawahlunto City. The purpose of this study is to determine the factors that affect the implementation of time management of road construction projects in Sawahlunto. The research method used is quantitative research method by spreading questionnaires to the respondents involved in road construction project in Sawahlunto City. Kata Kunci : Time Management, road, late
