Abstract

The loading aspect of a building is one of the factors that varies the dimensions of building components. Differences in building site areas are also contributed to the load received by buildings, especially in terms of earthquake loads. For the Province of Aceh with relatively high levels of earthquake vulnerability, the problems of structure dimensions change that caused by earthquake need to be specified. Changes to dimensions will affect the quantity of works, and furthermore against the building price standard. This research conducted to analyze the change of material quantity caused by earthquake load changes based on indication of acceleration of spectral response. This study was conducted by developing a model of simple building structure design and load change analyzed in 8 earthquake zones. The analysis focused specifically on the structural components of reinforced concrete columns. The information obtained from the analysis explains the effect of earthquake load changes from each of the observed zones on the use of reinforcing steel materials. The same condition is also seen in the ratio of reinforcement usage per cubic meter of concrete. The changes begin to be seen when the building model is positioned on zone 14 with an acceleration of 1.19g spectrum response.

Abstract

The construction involves a series of activities that possibly face problems or risks. The risk probability is an uncertain condition that results in a negative impact on the project objectives. Threats can come from the resources factor in a construction project, such as labour, materials, and equipment. The handling of risks in construction work needs to be further reviewed. It is to find risk factors and risk variables contributing to high risk to achieve the quality objectives of construction implementation. The purpose of this study was to analyze the most significant risk towards the quality of construction associated with the condition of the Province of Aceh during 2000-2015. The situation is classified in three periods, namely political conflict (2000-2004 as Period I), rehabilitation and reconstruction (2005-2009 as Period II), and post-rehabilitation and reconstruction (2010-2015 as Period III). Dataset is collected using questionnaires to 15 large qualified contractor companies to capture construction quality information. The risk significance identified based on Risk Importance Index (RII) for frequency and severity of factors and variables. There are 7 variables for labour resources, 10 variables for material resources, and 17 variables for equipment resources. The quality of construction mostly affected by the labour resources factors in Period I and Period III. The risk comes from the variable discipline of workers who are not good (A3). For Period II, the lack of labour capacity (A2) variable become as the most significant risk.

Abstract

The construction cost as one of the most important project resources should be planned and use efficiently. Cost estimation can be analysed using standard of unit price analysis according to Indonesian National Standard (SNI 7394:2008). Related to unit price analysis for tie beam reinforced concrete, the standard mentioned a specific analysis that combine all materials requirement include reinforcement (unit price analysis No. 6.29). In such analysis, reinforcement requirement is stated as much as 200 kg/m3 of concrete. Considering the diversity of dimension design of building structure caused by geographical location and building function, a further study required to response these problems. This research is aimed to provide information to what extent the unit price analysis related to tie beam reinforced concrete can be enforced in cost estimating. Research process initiated with secondary data collection to building construction located in zone 10 and 15 based on earthquake zone map (SNI 1726:2012) in Province of Aceh. The results of analysis informed that the ratio of reinforcement requirement of tie beam in zone 10 is 198.03 kg/m3 to 217.26 kg/m3 of concrete with average ratio 209.83 kg/m3. For zone 15, reinforcement requirement ratio is 203.76 kg/m3 to 233.83 kg/m3 of concrete with average ratio 215.17 kg/m3. The Potential inaccurate of cost estimation appears in the two review zones. Such inaccuracies may have an impact on the insufficient costs for the work. Thus, the use of the standard unit price analysis needs further assessment for proper application.

Abstract

The success of a construction project is determined by a number of factors. One of the factors that play a direct role is a job  productivity. Productivity can be expressed as the ability to complete a job within a certain time. The productivity is directly determined by the amount of the volume of work, the amount of labor/equipment, and implementation time. The larger the value of productivity, the greater the chance of a job can be completed by the target date. Therefor, this study aimed to assess the value of productivity on the bored pile foundation work. The study was conducted at the Project Tanjung Priok Access Road Construction Project (Phase I) Package 2, Section E-2, Cilincing - Jampea, North Jakarta. The study was  initiated with field observations, by observing the completion of all stages of the process, andshall record the amount of labor / equipment and the turnaround time at each stage of thework. The volume of work is analyzed based on the design drawings. Productivity values for each phase of implementation of the work are: 1) the work of pre boring 46.71 m³/hr; 2) installation of casing 115.69 m/hr; 3) drilling by bucket 9.74 m³/hr; 4) ry by the bucket 81.70 m³/hr; 5) Cleaning by airlift 10.81 m³/hr; 6) test Koden 313.05 m/hr; 7) nstallation of rebar30.37 m/hr; 8) tremie pipe fitting 88.11 m/hr; and 9) casting concrete 89.56 m³/hr.

Abstract

Scheduling is one of the first steps undertaken by project owners and contractors before executing the project. In this planning, one of the factors that greatly affect the project schedule is weather, especially rainfall. High rainfall could potentially lead to disaster and construction projects carried out in an open environment is very sensitive to the influence of the weather. This study aimed to predict/forecast the pattern of rainy days that will generate working days calendar. The methodology of the study was conducted by collecting historical data of rainfall and the time schedule of the project. Forecasting of rainydays pattern was done with Markov chain theory and Monte Carlo simulation. Forecasting results show that the pattern of rainy days in February and December are the month with the lowest availability of working days. While March and Mayare the month that has the highest availability of working days. The level of availability of working days in a year is 88.8%, thus the forecasting results can be used for project scheduling. The forecasting programs will be integrated within the development of framework in forecasting rainy days of construction project scheduling models that effected by raining.
