ABSTRACT: Denpasar Centralized Waste Water Treatment System Project Phase II (Pedungan Waste Water Network) was conducted in Fiscal Year 2015. The project has been undertaken to improve the service of domestic waste water from households, boarding houses, restaurants, hotels, as well as villas. Processing system used is the centralized piping system and the management of the local system IPLT (Faecal Matter Processing Installation) as well as expanding the waste water pipe network in the city of Denpasar. IPLT development is a project that is claimed as the project's first stool processing engine technology in Bali. Based on this, there is a need to study of the risks that occur during the construction of the project. The research was conducted through interviews along with personnel experience and expertise, manufacture and distribution of the questionnaire, doing a test from the result of questionnaire with test the validity and reliability risks that arise in the implementation of this project. Risks are obtained in this study a number of 71. The distribution of risk acceptability in the project as much as 8 (11.27%) risk (less precise drawings, project specifications and addendum provided by the owner), including unacceptable, 50 (70.42%) risk ( quality concrete Pile Anchorge that does not comply with the specifications approved) including undesirable, 9 (12.68%) risk (operational and overhead costs are high) including acceptable, 4 (5.63%) risk (the use of the funds out of contract ) including negligible. Risk mitigation is only given to major risk include risk unacceptable and undesirable risk. Based on the results of the risk management, implemented regulations on ownership of risk (risk ownership) against perpetrators (project owners, consultants, planners, consultants and contractor supervision) involved in the implementation of Denpasar centralized wastewater treatment system project.

Abstract

Sistem Manajemen Keselamatan dan Kesehatan Kerja (SMK3) wajib dilaksanakan pada setiap proyek infrastruktur yang akan berdampak pada biaya konstruksi. Masalah yang dihadapi adalah berapa biaya yang akan dikeluarkan untuk melaksanakan SMK3. Berdasarkan pernyataan tersebut, perlu dilakukan penelitian yang bertujuan untuk mengetahui faktor-faktor yang mempengaruhi biaya SMK3 pada proyek jalan dan prosentase biaya untuk penerapan SMK3 terhadap biaya proyek. Pengumpulan data dilaksanakan dengan kuesioner yang melibatkan 70 orang responden/sampel. Item kuesioner disusun berdasarkan surat edaran Menteri Pekerjaan Umum dan Perumahan Rakyat tahun 2015 tentang Biaya Penyelenggaraan SMK3. Sampel menggunakan metode purposive sampling yang melibatkan site manajer, petugas K3, cost estimator, quantity surveyor, pelaksana lapangan dan konsultan pengawas. Besarnya estimasi biaya SMK3 diperoleh hasil survey pada 32 proyek. Data dianalisis dengan analisis relatif indeks dan analisis faktor. Persentase terhadap biaya proyek dianalisis dengan regresi. Ada 9 faktor yang berpengaruh terhadap biaya SMK3 diurut berdasarkan nilai tertinggi sampai terendah yaitu faktor asuransi dan perijinan, faktor sosialisasi dan promosi K3, faktor personil K3, faktor penyiapan RK3K, factor rambu-rambu, factor lain-lain terkait pengendalian risiko K3, faktor fasilitas sarana kesehatan, factor alat pelindung kerja dan factor alat pelindung diri. Subfaktor yang dominan mempengaruhi biaya SMK3 adalah pembuatan manual prosedur kerja, pengarahan K3, pembatas area, sepatu kesalamatan, surat ijin operator, ahli K3/petugas K3, peralatan P3K, rambu–rambu peringatan dan lampu darurat. Selanjutnya, persentase biaya SMK3 terhadap biaya proyek dapat diestimasi dengan persamaan y = 1 x 10-9x^2 – 6 x 10-5x + 1,3406 dan nilai R2 = 0,4586.

Abstract

DEVELOPMENT OF COMPUTER BASED CONSTRUCTION PROJECT COST ESTIMATING SYSTEM ABSTRACT The process of calculating construction project cost estimates, especially detailed estimates, requires high accuracy and relatively long time depending on the size of the project, the number of estimators involved, the level of expertise and experience of the estimator. On the other hand, the advances in computer technology have not been fully optimized to aid cost estimation calculations. The objective of this research is to develop computer based cost estimation system of construction project. The system is designed to estimate project cost throughout the project life cycle both conceptual and detailed estimates. The method of development system used phased development which was modeled using Data Flow Diagrams (DFD) for process modeling, and Entity Relationship Diagram (ERD) for data modeling. Based on the results of weakness analysis on the old system, the proposed system architecture was using Client-Server Architecture model, with Microsoft SQL Server as database server. In the database server, it was created functions to serve requests for information sent by the client computer. To support the required information, the proposed concept integrated PBS (Product Breakdown Structure), WBS (Work Breakdown Structure) and RBS (Resource Breakdown Structure) to produce detailed cost estimation based on building components, work items and project resources. The cost estimation of the ongoing projects can be recorded as a database of cost estimation for future projects.

Abstract

Facilities in an airport requires maintenance activity in order to achieve excellent quality level and able to support activities at the airport to avoid negative impacts, which is the declining quality of the facility that can lead to lower levels of the productivity carried out in an airport. Maintenance facilities at Bali's Ngurah Rai airport need the maintenance costs planning. To get proper maintenance actions,  the maintenance costs early stages of planning phase needs to develop a model of facility maintenance costs that can provide the maintenance costs estimates quickly and accurately. To produce a maintenance costs model we should identify the maintenance activities that exist at Ngurah Rai airport. Maintenance costs data used is within the last 5 years (2007-2011). Using the Cost Significant Model methode and the linear regression equation it showed that several of the facility maintenace significantly affect the facility maintenance costs in the Ngurah Rai Airport which is the cost of passenger terminal building maintenance (X6), the cost of runway maintenance (X1), the cost of taxiway maintenance (X2), the cost of air conditioning installation maintenance (X14), the cost of road maintenance (X4), the cost of vehicle parking maintenance (X5), and the cost of navigation and communication equipment maintenance (X10). There is 3  linear regression equation model which is 1) Y = 11873745878,77 + 0,993 X1 + 0,826 X2 + 0,334 X4 + 1,181 X6, 2) Y = -698840481,94 + 1,327 X1 + 1,716 X2 + 5,516 X5+ 3,060 X14, and 3) Y = 82110363478,07 + 1,013 X1 - 17,223X5 + 22,406 X10 - 12,035 X14. After doing the Cost Model Factor (CMF) test to the three linear regression equation, the most accurate equation is linear regression equation Y = 82110363478,07 + 1,013 X1 - 17,223X5 + 22,406 X10 - 12,035 X14 that has the average ratio 0.006% of the actual cost, so it is the best facility maintenance cost model at Bali's Ngurah Rai Airport.

Abstract

Abstract: The construction procurement evaluation method using lowest price conforming methods often causes some quality problems for  owners and increases the probability of dispute and delay during the contract execution. On the other hand, merit point system evaluation method can provide quality assurance, but the procurement committees are often dificult to apply it, and to determaine mesurable criteria evaluation.Therefore, it is necessary for a more in-depth study to find out the criteria evaluation for construction procurement. The research conducted in Bali, and adopted inductive qualitative approach involving 45 experts participated in construction procurements using merit point system evaluation.Puposive sampling is applied to determine the respondents come from all actors included during procurement process. The data was collected through interviews, observation participant and questionnaires, and the Analytic Hierarchy Process (AHP) is choosed to analyse them. The result shows that : the merit point system evaluation for construction procurement can determine the contractor provides better quality than the lowest price conforming method when theevaluation criteria are clear, mesurable and transparant in the bidding document. There are two principle aspects that must be considered to assurethe quality that is: the technical aspect and the cost that weight consecutively 60% and 40%. The technical aspect comprises of : a) the existance of work plan (13.51%), comprising of construction methods (4.12%), supporting  equipment (4.05%), supporting material (3.46%), suporting workers (1.88%); b) competencies of human recources (19.91%), comprising of project management competencies(2.31%), existence of expert (7.92%) and certificated human resources (9.68%); c) existence of supporting equipments (15.54%) consisted of lifting support (4.79%), transportation support (6.17%), surveying support equipment(4.58%); d) the existing of time management (6.30%) consisted of network planning (4.13%), bar chart (1.03%), and S-curve (1.14%); and e) existence of quality assurance (2.14%) consisted of quality management system (1.95%), performance quality management (0.66%) and material management quality (2.14%). From price point of view, it must be evaluated the faireness of price and price offer that weighs consecutively 25.66% and 14.34%.

Abstract

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.
