Abstract

A good construction management can support the acceleration of the infrastructure construction and a low performance in implementation of the construction projects will lead to delay and cost overrun. This paper is intended to identify the risk factors which affect to performance of construction project. Gorontalo Hajj Dormitory construction project are not completed within the estimated scheduled and cost. Data in this research were collected through questionnaires from stakeholders. Regression model of an analysis result then simulated with Monte Carlo method and the variables in this model are the most dominant risk factor which influence on a performance. The most dominant risk for cost and schedule performance is bad condition during construction, incorrect of implementation methods, rework and equipment failure. The cost and schedule performance of the construction work are in poor condition. Generated statistical model is aligned with Earn Value Method and can be apply on the field.

Abstract

The exposure of high temperatures which exposed reinforced concrete beams will cause damage to the cement paste as a binding component of the materials and decrease the ability of the beam. The objective of the study is to identify the high temperatures effect which exposed reinforced concrete beams (10 x 15 x 100 cm), focusing on the bending stiffness, deflection and bending capacity. The tests were conducted in some temperature variations which are 400 ˚C, 600 ˚C and 800 ˚C with the heating concept based on the slow changes of surface temperature and the convective heat transfer, the normal beam specimens (27 ˚C) were also tested as control specimens. The results show that the bending capacity decreases as the heating temperature increases, followed by the decrease of bending stiffness and also the increase of deflection before the beam reaches the first yield, then there is an increase on the bending stiffness of the beam which have been exposed by high temperature at 400 ˚C after the first yield is reached.
