Effect of Delay on Profitability of Building Construction Projects

In construction, delay could be defined as the time overrun either beyond completion date specified in a contract, or beyond the date that the parties agreed upon for delivery of a project. It is a project slipping over its planned schedule and is considered as common problem in construction projects. The Indian construction sector has acted as an engine of growth for the Indian economy for over the past five-decades and becoming a basic input for the socio-economic development of the country. Construction is the second largest economic activity after agriculture, and has contributed around 6 to 9% of India's GDP over the past five years while registering 8 to 10% growth per annum. This paper refers to study effect of delay in construction industry particularly in profitability or economic factors. Keywords: Construction, Delay, Profitability, GDP, Economic factor

Agustian, Daden Metode Pelaksanaan Pekerjaan Strauss Pile Proyek Gedung Kejaksaan Negeri Majalengka

Construction work is divided into different scopes of work, including structural, architectural, MEP and others. The structure is a means that functions to distribute live loads and dead loads into the ground. One part of the structure is the foundation which is a part of the building construction whose task is to place and transmit the load of the upper part of the building to the subgrade. The selection of the type of foundation structure is carried out by taking into account the condition of the soil, the limitations imposed by the structure above it, the limitations of the surrounding environment, the cost and time of carrying out the work. For example, the Majalengka District Attorney's building construction project uses a Strauss Pile foundation as the lower. Strauss foundation is a type of foundation that is used to carry loads when hard soil that has a strong bearing capacity is located very deep from the ground surface. In this project, the implementation of the Strauss Pile work refers to the provisions that must have the ASTM D 1143-81 standard regarding static compressive loading, using concrete quality K300 and reinforcing steel Ø ≥ 10 BJTD 40 and Ø≤ 10 BJTP 24. The work process starts from a series of works Preparation includes administrative equipment, land clearing and measurements, then carrying out work starting from drilling using a mini crane auger to casting, and finally testing as a technical report.

Optimal Location for Tower Crane and Dynamic Trailer Parking in High-Rise Modular Building Construction Project

Optimization of tower crane positioning is essential in precast building construction to ensure that a crane is in the right position to offer the best value for placing precast elements. The first goal is the optimization of transportation distances made by tower cranes, which will address the issues of efficiency and cost. This is done in a way that provides for minimization of the distances that lie between the trailer parking where elements are parked, the tower crane, and the construction installation point. However, current research fails to address the dynamic movement efficiency of trailers, especially when handling multiple trailers and several models of tower cranes, making this scenario an optimization problem that is classified as NP-hard due to the likelihood of causing a combinatorial explosion. This work endeavors to present a new mathematical model that has been applied to the Genetic Algorithm (GA). The ideal demand-generated model is designed to solve the optimal model and position of tower cranes and the prospective positioning of trailers for parking. The feasibility and applicability of the method exploited in the study are also established through a project case study. When adopting the proposed planning model compared to the earlier planning scale, comparisons highlight a small yet significant saving of 6% in time and cost when lifting elements instead of providing them from the trailers by setting up a new on-site stockyard. In addition, a great deal of enhancement is also observed in the final solution aspects, where the developed GA has even reduced the operational time and cost by half a percent each. The results of this research offer best-practice approaches to the position analysis of tower cranes in precast building construction to bring scalability and cost optimization to bear on the construction business.

Assessment of Concrete Formwork Practices in Bahir Dar City, Ethiopia

Formwork is among the most determinant factors affecting the cost and completion time of construction projects. In this study, the erection practices, challenges, types, quality and cost of formwork on active building construction projects in Bahir Dar were assessed. The study uses, Questionnaires, site observations and oral interviews with project managers, office and site Engineers, construction managers and carpenters were used to organize and analyse data. From assessment, most of the contractors have given less attention to formwork erection and safety issues. Since the principal criteria for formwork selection are cost and traditional formwork erection, it impacts construction safety and reduces the concrete finishing and quality. Formwork erection is left as the task of carpenters and labourers. There is no proper supervision of the quality of formworks that guarantees construction workers' safety so it is vulnerable to physical injuries and affects employee’s health. From the study, timber formwork is the most dominant type of formwork used for the construction of slabs, beams, columns and stairs due to its availability and low cost. Burnt oil is used as a releasing agent in all construction projects that causes undesirable outputs in concrete surfaces.
