THE IMPLEMENTATION OF VALUE ENGINEERING ON SCHOOL BUILDING CONSTRUCTION PROJECT(CASE OF STUDY SANUR INDEPENDENT SCHOOL)ABSTRACTIn a construction project, the cost is one of the factors that determine the sustainability of the project, especially in the case of study school building project at Sanur Independent School. Because of that, the austerity measures undertaken to produce an economical construction project. The selection of materials and construction methods can precisely determine the amount of savings to be gained in the implementation of the construction project, wherein the choice of materials and alternative methods will not necessarily reduce nor change the value of the function, quality and architectural value of the project itself. Therefore there is a need for job costing analysis to control these aspects. One of the methods that used for cost efficiency in a construction project especially on the building construction is Value Engineering Method that is a systematic way of defining the value of a subject to its function so that an innovative and structured approach can be adopted with the aim of reducing unnecessary costs. By using this method can obtained two alternative combinations of designs such as , the best combination of alternative designs and the cheapest combination of alternative design, and based by the result of the researched, by using a combination of the best alternative design on this construction project wherein the initial BoQ have a value of Rp 2,003,372,657.68 obtained savings of Rp 36.492.428,34 atau 1,82 %. While using a combination of the cheapest alternative designs obtained savings of Rp 248,161,362.38 or 12.39 %.

RISK MANAGEMENT DURING IMPLEMENTATION OF HOTEL CONSTRUCTION PROJECT AT SARBAGITA AREA ABSTRACT Construction project is an unique project and constrained by cost, quality and time. During construction project implementation, problems are frequently occur that affect toward cost, quality and time. Therefore according to such matter, it is considerably necessary to conduct research concerning risk management. Risk management include risk identification, risk analysis, risk acceptance distribution, risk mitigation and risk ownership. This research was conducted through interview with expert parties in hotel construction project implementation at Sarbagita (Denpasar, Badung, Gianyar, and Tabanan) region. This research aimed to identify and determine risk acceptance level, determine dominant risk, conduct mitigation action and risk ownership allocation. Total risks identified in this research were 37 risks that consist of 19 risks according to literature and 18 new finding risks. Dominant risk in this research were 28 risks, classified into 19 undesirable risks and 9 unacceptable risks. Both risks frequently occur in upper structure work. The most frequent risk sources occur in undesirable and unacceptable risks were technical risk. Technical risk in unacceptable risk were difference between picture and actual field, inaccurate scheduling, picture problems from planner and material specification discontinuation. Technical risk in undesirable risk were mainly tools mobilization delay, working hours limitation, quality and specification inconsistency and material discontinuation. Mitigation action mostly performed in technical risk were such as communication escalation between involved parties and organization structure improvement and project administration. Largest risk ownership allocation were in contractor side. These were due to contractor as the most responsible party in construction project implementation.

Pembangunan proyek jalan masih banyak mengalami kendala penerapan spesifikasi umum 2010 (revisi 3) oleh penyedia jasa, hasil yang diharapkan tidak sesuai dengan mutu pekerjaan yang di isyaratkan. Penelitian ini bertujuan mengevaluasi terhadap hasil pekerjaan dengan mengetahui penyimpangan dan kegagalan kontraktor untuk memenuhi ketentuan spesifikasi pada divisi 3 sampai dengan divisi 7 yang sering mengalami ketidak sesuaian pada spesifikasi umum 2010. Metode pada penelitian ini menggunakana survey dan kuesioner. Responden dipilih berdasarkan purvosive sampling kemudian dianalisa dengan metode sebab akibat (fishbone Analysis) dan Root Cause Analysis (RCA). pekerjaan yang mengalami kendala ketidasuaian didominasi pekerjaan galian lapis pondasi agregat (95,83%) diikuti dengan pekerjaan galian dan campuran beraspal panas (83,33%), pasangan batu (75%), pekerjaan pelebaran dan perkerasan (70,83%). Kendala yang terjadi karena kurang tegasnya team dari kotraktor untuk melakukan metode pekerjaan, kordinasi kepada masyarakat yang membutuhkan waktu lama, kurangnya pengawasan di base camp dan membeli dari supplier yang membuat campuran berbeda saat bahan sampai di lokasi proyek. Upaya pencegahan yang dilakukan yaitu kontraktor agar bekerja sesuai spesifikasi dan metode kerja untuk mencapai mutu, harus di lakukan kordinasi dan kesepakatan antara PDAM, Desa, dan kontraktor sebelum di lakukan galian, apabila terkena galian tidak meminta ganti rugi, pemilihan bahan harus tepat, dan peningkatan quality control di quarry, baik untuk material, komposisi untuk mencapai spesifikasi yang diminta (PI, CBR, abrasi, ukuran butir), kordinasi atau bersurat, melakukan sosialisasi dan membuat kesepakatan kerja sama.

Many countries have established implementation strategies for the use of BIM in construction projects which have resulted in the widespread adoption of BIM. To catch up, the Ministry of PUPR has launched the Indonesia Digital Construction Roadmap 2017-2024 through 4 stages, namely the Adoption, Digitalization, Collaboration, and Integration stages. However, currently at the Adoption stage of the Roadmap, it is still focused on only a few PUPR infrastructure projects. This is due to problems such as the unavailability of policies and regulations for implementing BIM for the entire PUPR infrastructure sector, the lack of mastery of BIM from both Users and Service Providers, the project scale is not yet massive so that the price of BIM software is felt to be still burdening the Provider. This study aims to investigate the mastery of BIM through a study of the level of use, implementation, and identification of the dominant barriers to BIM adoption, especially for construction project actors in Bali. This research is expected to help construction industry practitioners to understand the challenges of BIM adoption in Bali. Data collection was carried out by survey method using a questionnaire. Respondents were selected using the purposive sampling method, namely experts in construction projects in Bali. The method of analysis is descriptive statistics which includes central tendency measurement, variability measurement, and the Relative Importance Index (RII). The survey results from all respondents showed that the adoption rate of BIM for construction project actors in Bali was 19%. Level of BIM implementation of construction project actors in Bali were 89% at BIM level 1 and 11% were at BIM level 2. The dominant obstacles in BIM adoption are the high cost of adoption, lack of experts, lack of government role in encouraging BIM adoption, difficulty changing work processes and there is no standard and protocol in applying BIM in the project.
