Abstract

Debate both technically and economically in the use of road construction used often occurs.One of them is the lower foundation layer as a working floor and transfer of load from the topcover layer to the subgrade. The purpose of this study was to obtain the level of technicaleffectiveness and the level of cost and time efficiency in the use of thin concrete and aggregategrade foundation layers from the Mangkurawang-Rapak Lambur road improvement projectin Tenggarong District. Rigid hardening is determined as the closing pavement. Technicallythe pavement plan design uses the 1993 AASHTO method while the 2017 binary analysismethod is used to compare costs and time. The results show that for a road improvementproject of 1,151 km with a subgrade CBR of 5%, the lower grade aggregate foundation B is15 cm thick with a planned budget of Rp. 5,153,245,000.00 while the time required is 49 days.Meanwhile for thin concrete 10 cm thick. With a budget plan of Rp. 6,147,623,000.00 within43 days. Means the bottom foundation layer aggregate class B 16.18% more efficient with atime of 12.24% more efficiency compared to thin concrete.Keywords: lower foundation layer, thin concrete, AASHTO, binamarga analysis

Abstract

One of the value engineering innovations in supporting a million housing program from theGovernment which is supervised by the Ministry of Public Works and Public Housing onhousing or residential assistance for low-income people, PT Duta Cipta Pakarperkasa whichis engaged in the Steel Industry has issued a simple house product Rupak using the concept ofgrowing houses with knockable walls made from Expandable Polystrane (foam foam) coatedwith steel plates. The purpose of this study was to obtain a comparison of the cost and time ofimplementation in building a simple Rupak and conventional type 36 house, namely by usinga descriptive analysis method that was processed to determine the RAB and standards used inRupak houses and conventional houses. It turned out to be the result that for a modest houseit needed Rp. 80,898,797.52 while for conventional simple houses Rp. 92,471,372.31. And interms of time a simple house needs 16 days whereas a conventional simple house needs 29days.Keywords: shapely houses, conventional simple houses, styrofoam, knock down walls

Abstract

The Sangkulirang-Bontang road improvement project is in the form of delays on the seventhweek of December amounting to 6.21%. The cause of the delay in the execution of work wasthe problem of asphalt work and thermoplast road marking equipment. This research isintended to obtain optimal solutions in order to catch up on project delays. There are twoalternatives that can be assessed, namely the first addition to the time of workimplementation using the amount of equipment available, and the second by increasing theamount of equipment used. It turned out that the first alternative cost was Rp. 18,349,500.24with a period of 17 days. The second alternative is the implementation cost of Rp.36,699,234.86 but with a processing time of 9 days. Because the first alternative is cheaperwith time still permissible, the first alternative is chosen. In order to catch up on work delays,planning and scheduling are obtained and the acceleration of the duration of the projectcompletion is 1 day from the initial project planning of 59.0%. And in terms of costs there isa difference in the contract value of Rp.5,565,986,000.00 with a total cost of work of Rp.4,647,256,026.19 or Rp. 505,998,154.81 amounting to 0.165%Keywords: planning and scheduling project, delays, crashing time, road improvement

Abstract

The work contract for the Surabaya-Gempol toll road relocation project Porong-Gempolpackage 2 Porong-Kejapanan has been signed, namely in the form of a lump sum contract.Due to a request from BPJT to change the design from 2 x 4 lanes to 2 x 6 lanes on theSurabaya-Gempol toll road relocation project, Porong-Gempol 2 Porong-Kejapanan, thecontractor intends to propose a contract change from a lump sum to a unit price contract.This study aims to determine and determine the factors that influence changes in the contract.It turns out that by distributing questionnaires, it can be found that there are five mainvariables, namely service users (X1), service providers (X2), third parties (X3), contracts (X4)and environment (X5) that affect the final outcome of contract change (Y). By using factoranalysis and stepwise regression analysis aided by the SPSS program, it was found that onlythe service user variable (X1) and the service provider variable (X2), which significantlyaffected the contract change dependent variable (Y). And that influence is expressed by therelationship Y = -1,171 + 0,268 X1 + 0,529 X2.Keywords: lump sum contract, unit price contract,  factor analysis, multiple regressionanalysis

Abstract

The underground road construction project in the satellite roundabout area is a project witha risk level that is difficult to predict, so an in-depth risk management analysis is needed.With the approach of the quality, cost and time specs, the dominant risk factors and changesin costs and time will be sought due to the influence of these risk factors. By using 35respondents, it turns out that the final results of the analysis show that from the aspect ofquality, the factor of planning changes, material lacking in quality, low productivity of worktools becomes the dominant risk factor. While from the aspect of time, it turns out that thefailure factor of the team / project management, planning changes, and planning errors arethe dominant risk factors. Meanwhile, in terms of cost aspects of project management factorsand traffic safety, structural excavation, geotextile work, rigid pavement are the dominantrisk factors and from the natural aspect and planning aspects become the dominant source ofrisk in terms of time and scope of structure work, general scope of work of in terms of cost. Asa result of these risk factors, it results in changes in costs for structural works of 75 million or53%, while in public works amounting to 63 million or 11% with changes in time> 30 days. Keywords: Risk analysis, underpass, risk factors, sources of risk

Abstract

To obtain a better profit without ignoring work safety and quality of work, the acceleration ofthe implementation of the work of a construction project can be done using the Crashing andFast Track method. The research objective is to determine the amount of cost and timeincurred by the acceleration of implementation and determine the magnitude of the difference in budget and time spent with the Crashing and Fast Track methods. The Crashing method uses 2 types of variables, namely the addition of 1 hour, 2 hours and 3 hours overtime, andthe addition of heavy equipment and labor, while the Fast Track method uses 3 times theoverlapping application of work items. It turns out that the most optimal result is the additionof 2 hours of overtime work for 163 days so there is a reduction in costs of Rp. 156,358,936,while the Fast Track Method obtained the most efficient results are the results of operationswith a total duration of 130 calendar days, and with a total cost of Rp. 16,812,941,734,38,while the difference between the total plan and the cost after Fast Track is: Rp.340,933,265.63. The Fast Track method is cheaper than the Crashing method which usesovertime hours for 2 hours.Keywords: acceleration of project time and cost, Crashing method, Fast Track method.
