Abstract

Nowadays, the minimization of project time and cost is an important issue. However, time and cost problems are difficult to solve. They are affected by the uncertain factor. Then, the construction project always fails to achieve the effectiveness of time and cost performance. It causes delays and cost overrun. In this research, SOS-NN-LSTM is required to establish the estimate schedule to completion (ESTC) and estimate cost to completion (ECTC) prediction model based on time now performance. Then, the prediction model will be integrated with MOSOS to obtain the optimal prediction value. The integration is needed because there is no direct equation to calculate the ESTC and ECTC. The Pareto curve identified based on the prediction values of MOSOS. The Pareto curve is used to determine the optimal trade-off between project duration and project cost. Then, the indifference curve is used to solve the trade-off problem between estimate schedule at completion (ESAC) dan estimate cost at completion (ECAC) which give the decision-maker preference.

Abstract

This research will discuss about contractors with concrete suppliers and formwork suppliers. The research is conducted to look for ranking criteria and sub-criteria used by contractors to selecting and evaluating concrete and formwork suppliers. The criteria and sub-criteria are refer to Ho et al., (2007) and three new sub-criteria are added, which are a guarantee, lowest price guarantee, and payment term. The contractor classification is divided into four namely general classification, NPK classification consisting of non-classification; individual; small business, medium business classification, and big business classification. Ranking for criteria and sub-criteria are sought based on the mean value for each classification material both in the context of selection and evaluation. After finding the ranking, it is sought whether there is a difference of importance between the NPK classification, middle, and large of the priority sub-criteria in general classification using the Kruskal Wallis test.

Abstract

This paper discusses the prefabricated construction method by taking a case study of Dian Sukolilo Regency housing construction, Surabaya. Prefabricated construction methods are able to provide faster construction times and better quality. Stages of research will be carried out by processing real data with a simulation calculation approach to obtain the calculation of the budget plan and estimated time of construction using the prefabrication method. The main variables that influence this prefabricated construction method are four namely cost, time, quality and number of units. The increasing number of units will reduce the cost of construction of the construction unit using the prefabrication method. The results of each research calculation will guide the interview to find out the response of the housing developer to the prefabricated construction method whose results will be the conclusion of the study.
