Indonesia Construction Service Law Relating to MRT Development Contracts: A Legal Review with Fidic International Contract

This research was very important because of incomplete regulations related to Late Payment Arrangements and Variation Procedure Arrangements which are regulated in the Construction Services Law because this was very necessary considering the complexity of problems that occur in the construction world in Indonesia. The amendments to the Implementing Regulations also needed to be improved as regulated in Article 51 of Presidential Regulation N0. 54 of 2010 concerning lump sum contracts, there were no price adjustments and additional work, because in fact any construction work for price adjustment and additional work almost always occurred and almost impossible to avoid. So that these regulations could not be applied in the field and could hinder the implementation of construction project work in Indonesia. It was because most of the construction projects in Indonesia required cooperation with foreign investors.

Maturity of procurement units for public construction projects in Indonesia

Indonesia’s construction sector has been a driving force in its economic growth over the last five years, before COVID-19 pandemic, due to massive government spending on infrastructure development. One of the resulting concerns has been the capacity of public procurement for construction works to select builders capable of delivering quality infrastructures. To address this concern, this paper presents a study to measure the maturity of procurement units for public construction projects. This study aimed to provide information for the Indonesian government in mitigating the risks related to its procurement unit’s capability of delivering its demanding infrastructure projects. This research used the maturity model developed specifically for construction public procurement. There were 48 respondents from the Ministry of Public Works and Housings’ 16 procurement units in 15 provinces. The analyses were conducted using descriptive statistics based on location groupings, overall maturity index, dimensions, and elements. The maturity of procurement units for construction projects remains at the second level of five. The need for further capacity-building programmes for procurement units in Indonesia is still relevant, especially the improvement of procurement planning as the first and most important part of the procurement processes.

Implementation of Lean Construction to Eliminate Waste: A Case Study Construction Project in Indonesia

Lean Construction (LC) presented innovative practices to maximize the production value and minimize the production waste during construction. The problem that frequently occurs in the project is delaying the schedule, leading to time and cost overrun. This research aims to eliminate waste that causes delay and inefficiency. Several LC techniques were carried out to improve the efficiency of this project, namely: Value Stream Mapping (VSM) to discover wastes and determine Process Efficiency Cycle (PCE); Waste Assessment Model (WAM) to identify the inter-relationship among wastes; Fishbone (Ishikawa) diagram analysis to get the root cause of the waste. Research results showed the three highest wastes: defect 14.06%, over production 21.44%, and the highest rank was unnecessary inventories 31.73%. After implementing LC techniques, the PCE increased from 72 % to 79%. The implication of this research is to provide recommendations to the project’s stakeholders in running the building construction to avoid delay and inefficiency.

Causes of delays in construction projects in the Province of Aceh, Indonesia.

Implementations of construction projects in Indonesia, especially in Aceh Province, are often delayed. Time, quality, and cost are three important components of planning a construction project. The benchmark for a successful construction project is the project completion time being in accordance with the time period specified in the contract. In project implementation, there is often a risk of delays in completing construction projects that can cause losses and fines; therefore, it is necessary to know the risk factors potentially causing project delays. The purpose of this study was to identify the risk factors causing delays greatly affecting construction projects in Aceh Province. The data used in this study were questionnaire data distributed to 68 respondents. The data processing methods included validity tests, reliability tests, and the construction of descriptive statistics. Ultimately, 60 delay factors were obtained; of these, 30 risk indicators were included in the very influential category with a mode value of (= 5), 29 delay risk indicators were in the high influence category with a mode value of (= 4), and one indicator was included in the category of medium influence (= 3).

Causes of work accidents and its impact on the road and bridge construction projects

The work accident of road and bridge construction projects in Indonesia is quite severe. Every year there is always news about work accidents in the project. While the construction of roads and bridges, especially in Eastern Indonesia, continues to be carried out actively by the government. This research purpose of analyzing the causes of work accidents and their impact on the project. Data were collected at the research location, institutions related to the construction of projects, totaling 40 respondents. Based on the results of the analysis with a multiple linear regression method, it appears that 31 variables causing occupational accidents and 13 impact variables arising from accidents still occur and are very influential with high probability values. Four recommendations were made to prevent fatal accidents in the construction of roads and bridges, in Eastern Indonesia, to improve safety conditions in the construction industry.

DETERMINATION OF FINANCIAL FEASIBILITY OF INDONESIA'S NEW CAPITAL ROAD CONSTRUCTION PROJECT USING SCENARIO ANALYSIS

The plan to relocate the Indonesian capital from Jakarta to East Kalimantan Province in 2024 requires a significant amount of 442 trillion Rupiah to construct various new capital infrastructure such as roads for transportation. This study aims to analyze the funding scheme for new capital road construction projects in Indonesia using two alternative financing, namely the National Budget and Public-Private Partnership (PPP). This study used quantitative methods with a scenario analysis approach to determine the best funding scheme based on regional economic growth and financial viability. This study did not consider the project management factors during the construction period and the quality factors of the roads built during the concession period. The results showed that road construction projects in the new capital city can be implemented using two financing schemes. The National Budget financing scheme will increase the percentage of the budget deficit to GDP in the first five years of development. The financing scheme through PPP can help the government overcome the budget deficit but requires the resilience of the government's budget during the project concession period.

BIM Implementation in Public Construction Projects in Indonesia

The delayed of BIM advancement in Indonesia has proffered that Indonesian government awareness to generate an optimum knowledge and research in BIM implementation is frequently low. In order to catalyst some infrastructure projects which based government projects, the contractor companies should put their creativity and their improved knowledge to win the government projects. Regarding the existing challenges that frequently exist in several projects, BIM has been appeared as a sophisticated technology-based solution to overcome them. However, the level of BIM development in Indonesia nowadays has not been confirmed yet due to the BIM research evolvement is slowly. Even though, there are some companies which has utilised BIM either in their companies or their project such as the construction of Bakauheni - Terbanggi Besar toll road, the construction of Solo - Kertosolo toll road, etc. Nevertheless, the effectiveness and efficiency of BIM utilisation in a contractor company need to measure as an attempting to assist BIM research evaluation in Indonesia. By the questionnaire survey, this research is going to find out how BIM take the responsibility to reduce the complexity of diversity project. Moreover, the benefits and drawbacks which BIM contributes for several projects which have already through BIM’s role need to assembly as a further consideration for Indonesian government to arrange the convenience regulation regards to adopt BIM as the obligations later. Additionally, the assessment of the stakeholder’s role in BIM also necessary to evaluate since the optimum of BIM’s assignment in construction industry involving not only the contractor but also the consultant and the owner. Thus, the research is expected to endowment the further knowledge for BIM implementation in Indonesia.

Identify of Occupational Health and Safety (OHS) cost component for Flyover Project by developing of safety plan based on Work Breakdown Structure (Case study: Erection girder using tandem crane)

Occupational, Health, and Safety (OHS) issues in Indonesia are still often overlooked. It appears that the number of work accidents is still high. Therefore, in early 2018 the government has decided to suspend all the elevated construction projects in Indonesia including Flyover Project. It causes negative impacts such as casualties, material, time, cost, etc. Two factors that most hinder OHS implementation in the project based on the contractor’s point of view are the high cost of OHS implementation and the safety cost provided for OHS implementation by the owner is inadequate or even none at all. Safety cost planning can be done accurately if the activities based on the Work Breakdown Structure (WBS) on the project can be well defined. The Activity-Based Costing method provides more accurate information especially on complex structures while can provide information on cost items. This study aimed to identify the OHS cost component of the Flyover Project based on standardized Work Breakdown Structure in erection girders application using the tandem crane, which is supported with archival analysis, expert judgment, and survey to obtain a decent budget and specifically allocated for the implementation of OHS to improve working safety conditions.

The research finding land acquisition delay as the top of delay factors in construction project in Indonesia.

Analysis of safety cost structure for electrical work in rental apartements projects in special capital district of Jakarta based on Work Breakdown Structure (WBS)

With the lack of rental housing needs still very large, the need for building rental apartments in the future is still very high. In the implementation of construction projects in Indonesia in general the number of work accidents also increased. The construction industry is a dangerous industry that often takes its toll. Referring to the Manpower Social Service Provider (BPJS) data, nationally the number of occupational accidents in the construction sector is recorded as the highest national sector work accident rate. Especially in electrical work, there are many work accidents during electrical work that endanger electrical workers. For this reason, it is necessary to make a simulation of SMK3 cost modeling in order to estimate the costs needed with minimum project information at an early stage. Activity-based cost calculation has emerged as a new approach that connects costs directly related to business activities with manufactured products. To make activity-based cost calculations, making WBS and determining work items appropriately is a useful effort and is needed for effective activity-based risk assessment. So based on the above findings, given the high plan of building rental flats, the high number of occupational accidents and the lack of comprehensive OSH funding, this study focuses on developing OSH costs for the electrical component work in rental flats in DKI Province. Jakarta-based WBS.

Analysis cost of safety on project irrigation/channel base on WBS (Work Breakdown Structure)

The implementation of construction projects in Indonesia in general the number of work accidents also increased. Referring from BPJS, nationally the number of work accident accidents in the construction sector was recorded as the national sector with the highest number of occupational accidents. The regulations regarding OHS financing in Indonesia have not been clearly and measurably regulated. Existing regulations regarding HSE financing are regulated in three regulations, namely, Permen PUPR No. 31/2015, SE Menteri PUPR No. 66/2015, Permen PUPR No. 28/2016, and the last in SE Menteri PUPR No. 11/2019. Activity-Based Costing (ABC) has emerged as a new approach that connects costs directly related to business activities with manufactured products. This study aims to identify any risks that are potentially hazardous in irrigation work, making a safety plan using risk-based WBS standards, and the results of this research can make Analysis cost of safety for irrigation works.

Working posture analysis of wall building activities in construction works using the OWAS method

Activities of construction works are carried out manually and continuously with critical and repetitive working postures. The poor working condition causes fatigue, musculoskeletal disorder, in the worst case could lead to working accident. The paper discussed critical working postures of construction works of house construction project in Indonesia. Three mains activities have been identified to be studied, namely building up the brick wall, plastering the wall, and casting the concrete column. The activities were video recorded, the dimension of the work place and its component were measured and further analyzed in ergonomics laboratory. The postures were studied using Ovako Working Posture Analysis System (OWAS) method to identify their critical levels. The improvements were proposed to remove the critical posture and reduce the risk of injury. Result of the study showed that building up the brick wall was the most critical task since it has 2 critical postures, while plastering the wall and casting the concrete column have 1 critical posture respectively. The propose improvement has successfully removed the critical posture and reduce the risk of injury.

STUDI EKSPLORASI FAKTOR-FAKTOR KESUKSESAN PROYEK KONSTRUKSI DI INDONESIA

The high rate of growth of the construction sector in Indonesia has not been matched by its level of success. Problems are still found in many construction projects that result in project unsuccessfulness, including time loss and bad quality work. In order to support the success of construction projects in Indonesia, the aim of this study is to determine the critical factors that influence the success of construction projects in Indonesia.

Development of risk-based standardized Work Breakdown Structure (WBS) to improve time performance on high-speed railway construction project

In Indonesia plans and studies for High Speed Railway (HSR) are not a new idea as they have been conducted before 2010. However, the plan to build HSR was just recently announced in 2015. Specifically, for the high-speed railway construction project in Indonesia, there is no standards that contains details of work activity packages and their methods for carrying out work in the field. This resulted in every railway-based construction project still using several methods from both overseas and Indonesian domestic experiences. Therefore, it is now necessary to standardize both the methods and work activities and suggested to be implemented for any highspeed railway project so that the work breakdown structure (WBS) can be standardized for any future rail and rail-based construction project. This can also minimize any potential risks and ensure the project is completed according to the targets in terms of quality, cost, and time. The methodology used in this study are to identify risks at construction project with a WBS matrix (observation and questionnaire). Analysis data in this study used statistical analysis. The result of this study is 15 risks selected from the 3 highest risks and 1 risk representing each category. The 3 (three) highest are Delay in issuing designs by the planner / designer, Delay in land acquisition by the project owner, Work activity has stopped due to weather factors. Risk representing each category are The subcontractor’s productivity does not match planning (Work packages), Delay in issuing designs by the planner / designer (Method/design), Work activity has stopped due to weather factors (Activity), Delay from suppliers in delivering material (Material resources), The planned productivity of equipment is not as needed (Equipment resources) and Human productivity is lower than demand (Human resources).

Cost Overrun in Construction Projects in Indonesia

Cost overrun is one of the problems faced by most construction projects in Indonesia. The unexpected budget in cost overrun can raise many problems in the project. Hence, it is important for every stakeholder in the project to have a good understanding of the factors causing cost overrun to avoid or to minimize the risk of it in the project. The aims of this study are to identify factors causing cost overrun in a project and to analyze factors that most influence the occurrence of cost overrun in construction projects in Indonesia as perceived by the owner and contractor. This research used a questionnaire to collect data. 15 factors were identified in this research i.e. site availability delay; site conditions; social site conditions; change order; rework; subcontractor and/or vendor performance; approval/permit delay; inaccuracy in budgeting; scheduling and resource planning; materials price fluctuations; rules and regulations; owner additional requirements; inflation; delay in payment; weak cash flow and bad weather. From a total of the 15 factors identified, both parties agreed on rework as the most factor causing cost overrun in construction projects in Indonesia.

The Development of Safety Plan Using Work Breakdown Structure (WBS) for Building Information Modeling (BIM)-Based Building Structure Work

One of the most influential factors on the project success in the construction industry is the safety management system. The rate of the occupational accidents in the construction sector is still very high according to the report of the Institution of Social Security Employment in Indonesia. One of the causes of the high rate of the occupational accidents that occur is due to the unnoticed work activities which is caused by the lack of control on the risks of the work activities. To discovered all of the activities on a work package, we can use a tool called WBS or Work Breakdown Structure. Besides that, by using the advancement of technology, it is expected to be used to improve safety performance on the construction projects effectively and efficiently. One of the advancements of technology which is already been used in the construction sector on this era is the BIM (Building Information Modeling). With using the BIM system on the construction projects, the quality of the work during the planning and construction phase will be increasing. Therefore, the development of a safety plan using WBS for BIM-based building structure work will be carried out in this study. The research method in this paper is a qualitative method and a case study will be presented on this paper to find out the effectiveness with using BIM in the safety management process. The results of this research are the occupational accident risks that are dominantly using the WBS and the development of the safety plan using WBS for BIM-based building structures work. The case study results the integrating of safety building information with the 4D model is very effective and efficient method to use on the safety management process. With the BIM system in the safety management process, the budget and the duration for safety inspection can be reduced because the hazardous of the occupational accidents can be identified faster according to the construction schedule. This research is expected to create a safety management strategy and can improve the safety performance on building construction projects in Indonesia.

Cost overrun and time delay of construction project in Indonesia

The success factors of project was completing the project without time delay and cost overrun. Time delay and cost overrun were arised due to uncertainty activity during the life cycle project. This may lead the problems to the project. The research aim was analysing cost overrun and time delay in construction project. Data were collected using questionnaire to 36 respondent. 15 factors have been identified in this research i.e land acquisition delay, location of site, support or protest from the local for the project, changes in design specifications, rework, subcontractors and vendors performance, delay in works approval, inaccurate budgeting and resource planning, price escalation of materials, rules and regulations of the government, owners additional required, inflation, payment delay, weak cash flow and bad weather. The result findings, owners and contractors have differences and similarty perception. In cost overrun factors, owner agreed the topmost factor causing was owner additional required while according to the contractors was rework. In delay factors, owner agreed the topmost factor causing delay was inaccurate budgeting and resource planning while according to the contractors was land acquisition delay. Nevertheless, both parties agreed the inflation has a least influent to construction project delay.

Study on Constraint on the Readiness of Using Building Information Modelling (BIM) for Construction Project in Indonesia

Building Information Modeling (BIM) is a paradigm shift that has many benefits, not only for those engaged in building construction but also for the wider community. The benefits of BIM include a more integrated design and construction process, resulting in better quality buildings, lower costs and lower duration. However, to master BIM in Indonesia, many factors have not been achieved. This study uses the Analytical Hierarchy Process (AHP) to get the constraint factors for the readiness of using BIM in Indonesia which consists of 3 criteria in which there are 19 sub-criteria. There are 5 (five) experts who have competence in the field of building Information Modeling with at least 10 years of experience carrying out the assessment. The results of expert research show that the most dominant factors on the readiness of using BIM are Maturity in Understanding BIM.

Development of Safety Cost for Architectural Works in Rental Apartments Building Construction Project Based on Work Breakdown Structure

The government of Indonesia is targeting a supply shortage or housing backlog in 2019 to be 5.4 million. With the shortage of rental housing needs that are still very large, the development needs of rental flats in the future are still very high. But on the other hand, the implementation of construction projects in Indonesia, in general, the number of work accidents also increased. Referring to Labor Social Service Agency (BPJS) data, nationally the number of occupational accidents in the construction sector is recorded as the most national sector of the number of occupational accidents. Managerial finance is important to assist the process of making decisions related to work safety. While the regulations and provisions concerning occupational, health, and safety (OHS) financing in Indonesia in the construction sector, especially in buildings, have not been clearly and measurably regulated. In its implementation, the existing regulations have not been fully followed by construction actors even within the Ministry of Public Works and Public Housing itself. Architectural works on building construction, in this case, the construction of rental apartments is a job that has the highest number of work items compared to other types of work items. This study resulted in standardized Work Breakdown Structure, safety risks identification, mitigation risks and the component of safety cost for Architectural Works in Rental Apartments Building Construction Project.
