Abstract

Almost all regions of Indonesia are geographically vulnerable to natural disasters, earthquake. One way to implement a very long and structurally stable building design in the event of an earthquake or other circumstances is to provide a dilation system for the building. This research was conducted in a multi-storey parking building project at Airlangga University Campus B which applies a cantilever beam dilatation system and will be compared with a two-column dilatation system in terms of cost and time. Cantilever beam dilatation is a structural separation that uses a beam structure with one end having a clamp and the other end is free, while two-column dilatation is a structural separation that uses two columns side by side with a certain distance. From the results of the study, it was found that the cost of structural work with cantilever beam dilatation was Rp. 76,755,100,000, - and for two-column dilatation is Rp. 76.063.550.000,- while the total project time with cantilever beam dilatation is 451 working days, and for two-column dilatation is 447 working days. The application of two-column dilatation is 0.9% more cheaper and four days earlier than the application of the cantilever beam dilatation system.

Abstract

The success of construction project is determined by the management of cost, quality, and time. Mismatches between the initial plan and field conditions often cause delays and cost overruns. Project X with a cost of IDR 4,144,190,311.75 with a planned implementation time of 180 days, experienced a delay with a deviation of -10.09% on the 91st day. This study aims to analyze project acceleration to delays solution by implementing the evaluation variance at schedule method, earned value and time cost trade off method. The results of the study using the evaluation variance at schedule method, that the delay manajement index was 0.36, and delay production index was 0,64. This delay caused by delay of material arrivals, low labor productivity, and low skilled workers in project. With the earned value, the estimated project completion time was 215 days, its mean 35 days late with an estimated project completion cost of IDR 4,775,028,805.39. The result time cost trade off method with the addition of work shifts, add cost IDR 780,771,895.34 and total cost is IDR 4,924,962,207.09 and 180 days. With the addition of working hours (overtime), add cost IDR 836,528,250.97 and total cost is IDR 4,980,718.562.72 and 188 days. The addition of work shifts is recommended for delay solution.
