The Impact

The article discusses the important applied problem dedicated to the theoretical and methodological justification for assessing the impact of business potential on the controllability of an investment-construction project. It is proved that the business potential of the investment-construction project characterizes its potential managing opportunities. In the article the terms of the theory of controlled development of investment-construction projects are formalized. Business potential of the project is considered as a set of four components: organizationally-technological, economic, financial and human resources. In order to determine the level of controllability of the investment-construction project business potential, an algorithm was developed for assessing the project. This algorithm involves four basic stages: preparation, application development, analytical and operational stages. The algorithm developed in the article was approved by an example of the project for the construction of a car showroom. The level of investment-construction project business potential sustainability is defined by a special scale. The results of the project business potential assessment allow to make target regulation solutions for the project development.

Abstract Construction Projects is one form of activity that takes place in a limited period of time, with certain resources, to achieve results in the form of buildings or infrastructure. Construction projects involve contractors, project owners, planning consultants and supervisory consultants that are interrelated in a work agreement called a contract. Project delays for contractors will experience a loss of time and costs, because the benefits expected by the contractor will decrease or even not get the expected benefits that they may not even benefit at all. The delay in the completion of the project work will cause a loss to the Owner to the operating time of the project results, so that the use of the project development results will be delayed or late. The success of a construction project is determined by the suitability of time, cost and quality stipulated in the contract document. In the implementation of construction projects delays often occur due to the parties involved. This research was conducted with the aim of finding out the factors causing delays in the implementation of construction projects according to contractors, project owners and supervisory consultants. Conducted by distributing questionnaires to contractors, supervisors and consultants, the results obtained were processed using the SPSS program. The results of the study revealed that the factors that caused the delay in construction projects were the 3 most dominant were the lack of skilled labor in the category of human resources Unexpected weather falls into the category of external aspects, and differences in interpretation of work codes fall into the categories of organization, coordination and communication aspects Abstrak Proyek Konstruksi merupakan salah satu bentuk kegiatan yang berlangsung dalam jangka waktu terbatas, dengan sumber daya tertentu, untuk mencapai hasil dalam bentuk bangunan atau infrastruktur. Proyek konstruksi melibatkan kontraktor, pemilik proyek, konsultan perencana dan konsultan pengawas yang saling terkait dalam sebuah perjanjian kerja yang disebut kontrak. Keterlambatan   proyek   bagi   kontraktor akan  mengalami  kerugian  waktu dan  biaya, karena keuntungan yang diharapkan oleh kontraktor  akan berkurang atau  bahkan tidak mendapatkan keuntungan yang diharapkan bahkan  bisa tidak mendapat keuntungan sama sekali. Keterlambatan penyelesaian  pekerjaan  proyek akan menyebabkan  kerugian bagi Owner  terhadap  waktu operasi hasil proyek, sehingga penggunaan hasi pembangunan proyek menjadi mundur atau terlambat. Keberhasilan suatu proyek konstruksi ditentukan dari kesesuaian waktu, biaya dan mutu yang ditetapkan dalam dokumen kontrak. Dalam pelaksanaan proyek konstruksi sering terjadi keterlambatan yang disebabkan oleh pihak- pihak yang terlibat.  Penelitian ini dilakukan dengan tujuan untuk mengetahui factor penyebab keterlambatan pelaksanaan proyek konstruksi menurut kontraktor, pemilik proyek dan konsultas pengawas. Dilakukan dengan menyebarkan kuisioner kepada kontraktor, pemilik dan konsultan pengawas, hasil yang diperoleh diolah menggunakan program SPSS, Hasil penelitian  tersebut diketahui bahwa factor penyebab keterlambatan pelaksanaan proyek konstrusi terdapat 3 yang paling dominan adalah Kurangnya tenaga kerja terampil masuk dalam kategori aspek sumber daya manusia, keadaan cuaca yang tak terduga masuk dalam kategori aspek eksternal, dan perbedaan intepretasi kode pekerjaan masuk dalam kategori aspek organisasi, koordinasi dan komunikasi.

The Impact

Risk is a condition caused by uncertainty. Risks will occur on any construction project, including bridge construction projects. Efforts that can be taken to minimize the impact of these risks are to engage in risk management activities. This research was conducted on bridge construction work on toll road procurement project in Pejagan-Pemalang, Pemalang-Batang and Salatiga-Kertasura. The purpose of this research is to analyze the risk of bridge development project in toll road project using Risk Breakdown Structure (RBS) method and then the result as database in discussing risk response strategy. The bridge construction project has 36 risks that are divided into six groups: materials and equipment, design, human resources, finance, management, nature and environmental conditions. Bad weather risks are the higest risk and seasonal risk causing temporary work stoppages. This risk-response strategy is avoidance. Short-term avoidance response strategy is to add shift workers, install tents and add additives in the acceleration of the process of maturation of concrete. The long-term avoidance response strategy is to evaluate and rearrange the work schedule by considering the weather forecast report.

Craft Worker

Purpose This paper aims to quantify the impact of craft worker shortage on construction project safety performance. Design/methodology/approach A database of 50 North American construction projects completed between 2001 and 2014 was compiled by taking information from a research project survey and the Construction Industry Institute Benchmarking and Metrics Database. The t-test and Mann-Whitney test were used to determine whether there was a significant difference in construction project safety performance on projects with craft worker recruiting difficulty. Poisson regression analysis was then used to examine the relationship between craft worker recruiting difficulty and Occupational Safety and Health Administration Total Number of Recordable Incident Cases per 200,000 Actual Direct Work Hours (TRIR) on construction projects. Findings The result showed that the TRIR distribution of a group of projects that reported craft worker recruiting difficulty tended to be higher than the TRIR distribution of a group of projects with no craft worker recruiting difficulty (p-value = 0.004). Moreover, the average TRIR of the projects that reported craft worker recruiting difficulty was more than two times the average TRIR of projects that experienced no craft recruiting difficulty (p-value = 0.035). Furthermore, the Poisson regression analysis demonstrated that there was a positive exponential relationship between craft worker recruiting difficulty and TRIR in construction projects (p-value = 0.004). Research limitations/implications The projects used to construct the database are heavily weighted towards industrial construction. Practical implications There have been significant long-term gains in construction safety within the USA. However, if recent craft shortages continue, the quantitative analyses presented herein indicate a strong possibility that more safety incidents will occur unless the shortages are reversed. Innovative construction means and methods should be developed and adopted to work in a safe manner with a less qualified workforce. Originality/value The Poisson regression model is the first model that quantifiably links project craft worker availability to construction project safety performance.

Construction projects in all regions continues to be developed for the creation of facilities that can be utilized by the community. One of them is the construction of apartments which are now being intensively carried out to meet residential needs for the community. Making a construction project plan always refers to estimates that exist at the time development plan is made, therefore problems can arise if there is a discrepancy between the plans that have been made and the actual reality. So the impact that often occurs is the delay in the time of project implementation which can also be accompanied by an increase in the cost of implementing the project. In the construction project of Cinere Terrace Suites Apartemen & Citywalk, Jakarta there was a delay resulting in a late payment of monthly bill progress by the owner. Based on the above reasons, this research was conducted to find out how the project performance was seen from the cost and time period of the review period. how is the estimated cost and time to complete the overall project work. The method used in the analysis of this study is the Earned Value Method. Based on the results of the analysis carried out for 29 weeks the project performance on schedule has been delayed and cost shows a positive value. For the estimated completion time of the project there is an increase in time whose duration increases from the planned 98 weeks or 685 days to 109,624 weeks or 768 days. While the estimated cost of completing the project from the results of the analysis obtained a value of Rp. 270,147,448,569.16 smaller than the planned cost of Rp. 315,272,727,272.73. With the difference VAC of Rp. 45,125,278,703.57 this shows that there are benefits obtained by the contractor.

The Impact

According to the concept of a system-based approach, a construction project can be treated as a complex system composed of various elements, such as human, equipment and material resources, as well as knowledge and tasks that are mutually interlinked. In the classical approach to construction project risk assessment, the impact of the “system” in the analysis of relationships between risk sources and their consequences has so far been neglected. The concept of construction project vulnerability and its adaptability has appeared in literature in recent years. It is analysed on the basis of a project’s vulnerability to the impact of risk factors and its adaptive capacity is seen an answer to project perturbations caused by adverse random events. As a part of developing the system-based approach to analysing construction project schedule, the author further developed the concept of modelling planned construction projects with relationship meta-networks composed of four types of nodes: agents (human resources), knowledge, equipment and material resources and tasks. The author included possible deviations from the planned project’s budget in the schedule vulnerability and adaptability analysis, instead of only focusing on deviations from its completion deadline. An analysis of the occurrence of additional and replacement work was introduced by the author, which further developed the concept of the simulated evolution of such networks to include the capacity to introduce new nodes and links into their structure. Furthermore, the author used the potential of weighted meta-networks to model certain dependencies within the planned project. A simulation-based approach as a part of DNA (dynamic network analysis) was used to analyse the vulnerability and adaptability of such networks. The proposed approach was presented on the example of a renovation project performed on a historical structure. The conclusions drawn from the author’s analyses can be used to formulate construction project schedules that are less vulnerable to perturbations and are characterised by greater adaptability. In the future, the author plans to expand the analysis presented above to include dependencies in single-mode networks (e.g. in agent, resource or knowledge networks) on the meta-network of a project.
