Abstract

The progress of construction work has different deviations at a certain point in time. Various factors cause inequality. A positive progress deviation indicates that construction work is completed faster where the progress of the plan is lower than the actual one, otherwise it is said to be late if it is negative. The uncertain nature of construction work causes there are 3 (three) scenarios of possible progress deviation values, so that these three values ​​form one expected progress deviation value. A deviation of value greater than negative 10% for a duration from 0 to 70% is categorized as a critical contract. The purpose of this study was to determine the deviation of the progress of 29 construction works. Data collection was carried out on 29 construction works that had been carried out. The data is taken directly from the contractor. The results of data analysis showed that at 10% D, 11 construction works with poor performance were obtained. Information was also obtained that the construction work No. 12 have critical contracts (-11,773). Furthermore for the current construction work 30%D. 50% D and 70% D number of poorly performing construction works 12; 10; and 9. The value of the largest positive progress deviation is 15,362 at the 70% time point D. The expected value of the largest positive progress deviation is positive 1.763. By knowing the expected negative progress value, the contractor must exercise control as soon as possible before the contract expires. Acceleration can be done on activities that are on the critical path

Abstract

The development process requires relationships between the parties involved in a project, generally differentiated into functional relationships, namely patterns of relationships related to these parties’ functions and formal working relationships, namely patterns of relationships related to cooperation between the parties. parties involved in a construction project confirmed by a contract document. The method in this research is qualitative. The results in this study increased the duration of the work and several days of the project there was no work because the foundation work was on a critical trajectory and there was a need for cooperation and communication within the Police. If one job has experienced delays, to catch up on delays so that the project does not experience delays as a whole is to speed up the superstructure work. One way is to provide formwork for more floors, so that the superstructure work can be completed more quickly with good management at the National Police level.

Abstract

In a project, it is necessary to have a work between owners and contractors that are used as a legal basis, in the form of construction contracts. One of these contracts is a contract for the procurement of goods and services based on the charge of its fiscal year consisting of a single-year contract which is the execution of a contract of work binding funds for 1 year while the contract of the plural year is a contract for the execution of work for a period of more than one fiscal year on the budget. Project delays almost occur every year and this results in huge losses for service users and service providers both in terms of finance and time. Project delays are divided into several types, namely: excusable delays, unforgivable delays, and delays that get compensation. Project delays are caused by several factors such as late payments and design changes. This factor greatly affects the performance of implementation in the field. The research process is carried out by conducting a survey. Starting with disseminating questionnaires to Owners, Contracts and outside parties as well as through literature studies, it is carried out to find out the comparison of the causes of project delays

Abstract

Pondasi dalam merupakan struktur bawah suatu konstruksi yang berfungsi untuk meneruskan beban konstruksi ke lapisan tanah keras yang berada jauh dari permukaan tanah. Penelitian ini bertujuan untuk memberikan gambaran respon daya dukung aksial tiang bor tunggal diameter 1000mm melalui pendekatan matematis berdasarkan hasil pengujian yang dilakukan. Daya dukung aksial rencana diperkirakan melalui analisis hasil penyelidikan tanah (hasil uji N-SPT, hasil uji DCPT, dan hasil pemeriksaan laboratorium), daya dukung aksial aktual diperoleh melalui interpretasi hasil Uji Beban Statis (SLT) dengan metode Davisson, Mazurkiewicz, dan Chin, sedangkan hasil uji beban PDA (Pile Driving Analyzer) dianalisis menggunakan aplikasi CAP-WAP. Daya dukung aksial direncanakan sebesar 250ton, sedangkan daya dukung aksial rata-rata berdasarkan hasil interpretasi SLT pada tiga tiang pancang yang diuji dengan metode Davisson, Mazurkiewicz, dan Chin berturut-turut sebesar 385; 448; dan 216ton. Nilai daya dukung aktual berdasarkan hasil pengujian PDA adalah sebesar 565ton. Hasil analisa tersebut diperbandingkan dengan nilai daya dukung rencana dan daya dukung uji SLT, sehingga diperoleh nilai Bearing Capacity Ratio (BCR). Berdasarkan interpretasi uji PDA dan CAP-WAP nilai BCR berturut-turut adalah sebesar 62.8% dan 67.8%. Nilai BCR berdasarkan interpretasi hasil uji SLT sebesar 42.8%, 48,0%, dan 25,5%. Dengan demikian, tiang bor tersebut berada dalam kondisi kinerja yang buruk. Dengan membandingkan nilai BCR terhadap beban uji rencana, diperoleh nilai rasio daya dukung (BCR) berdasarkan interpretasi uji PDA dan CAP-WAP berturut-turut sebesar 226.0% dan 244.4%. Nilai BCR berdasarkan interpretasi hasil uji SLT dengan metode Davisson, Mazurkiewicz, dan Chin berturut-turut sebesar 154.0%, 172.8%, dan 91.9%. Dengan demikian, interpretasi menggunakan metode Davisson dan Mazurkiewicz menunjukkan nilai BCR lebih dari 1,5 yang berarti pemilihan beban rencana pada saat SLT cenderung konservatif. Namun, mengingat nilai faktor keamanan yang memadai diperlukan, maka pondasi tersebut dianggap berfungsi dengan baik. Sedangkan berbeda dengan metode Chin yang nilai BCR-nya kurang dari 1, artinya pondasi menerima beban melebihi daya dukungnya. Hal ini perlu menjadi pertimbangan, apakah terdapat ketidaksesuaian metode yang diterapkan, kesalahan dalam proses penafsiran data, atau jika dan hanya jika analisis dengan metode Chin lebih akurat, maka perlu dilakukan perkuatan pada sistem pondasi.
