Abstract

Construction projects have three targets that must be achieved, namely accuracy of cost, time and quality. These three targets are influenced by work productivity. However, in the implementation of construction projects there are often delays. So, contractors usually do various ways to catch up on project delays. One of the things that contractors do to speed up work is by adding working hours outside of regular working hours or overtime. When working during regular working hours, there will be different conditions during overtime, causing differences in productivity levels between the two. The amount of productivity produced is influenced by many factors. Factors, such as field conditions and supporting facilities, job skills, age, experience, and field management. This study was conducted using observation and questionnaire methods. The observation method is carried out by measuring the implementation of work during normal and overtime hours and recording activities. Questionnaires were distributed to workers to obtain factors that affect labor productivity. The results obtained were average productivity during normal hours of 2,018 m2/hour and overtime hours of 2,043 m2/hour. The average LUR value during normal working hours is 61.39% and overtime hours is 64.66%. In addition, factors that greatly influence are workers' wages, weather conditions, work area conditions, and lack of rest time.

Abstract

Determining the bid price in a construction project tender is faced with a trade-off between the optimum markup value, expected profit and the chance of winning the tender. This research aims to report the research results on the best offer price strategy model. This research was carried out by analyzing secondary data on building work tender package prices in DKI Jakarta Province. The data analysis used the Friedman and Gates method with a single and multiple normal distribution statistical approach. Friedman and Gates model calculations are discussed in this research. This paper also discusses the trade-off between markup and profit and the probability of winning a tender based on the project value category. This research shows that the Friedman Model is better used for project sizes of 1 - 10 billion Rupiah, while the Gates Model and Friedman Model produce the same output for project sizes of IDR 15 - 50 billion and greater than IDR 50 billion. Based on this, the results of this research can be used to determine the optimum bid price according to the amount of markup and probability of winning.

Abstract

Depending on the material's origin, fiber reinforcement might be classified as waste, synthetic, or natural. Reinforcements made of natural fibers, such plant roots, are biodegradable, environmentally friendly, and have a good impact. Moreover, these fibers are lightweight and extremely rigid, which makes them ideal for improving soil. This research aims to study the effect of plant root reinforcement on the shear strength properties of soils. Soil and root fibers were collected within Universiti Malaysia Sabah Campus before being classified using existing standard. Direct shear box tests were conducted to determine the shear strength of the samples upon mixing with different root types (grass, shrub) at different percentages (0%, 2%, 4%, 6%). Results found that highest cohesion improvement is observed in soil SW-SM and shrub (VH-type) combination. In almost all cases, only insignificance effect is observed in the angle of friction. In conclusion, it was determined that the inclusion of root fiber improves the adhesion and the shear strength properties of the soil.

Abstract

On the road section between Padang City and Padang Panjang City, the geometric conditions of the road are steep and winding, making it difficult for drivers when they are in a convoy of vehicles, thus allowing accidents to occur. Therefore, a headway value is needed to control the safe distance between vehicles so that there are no collisions between vehicles when convoying. This study aims to determine the distribution of traffic headway on steep roads with sharp bends. The study took traffic flow data at 2 observation posts on the Sutan Syahrir, Silaing Bawah road section. Primary data collection was carried out using a camera. Data processing used Avidemux and Microsoft Excel software. To obtain the best distribution model on steep roads with sharp bends, a Kolmogorov-Smirnov test was carried out using EasyFit Professional software. Based on the data analysis, the following results were obtained: Based on the z test, the results of the analysis of downhill and uphill flows on the first and second days of observation can be concluded that the headway of the vehicle population at Post I and Post II has the same population headway. The best distribution model (goodness of fit) from the results of the time headway test for Saturday at the first post is the Johnson SB model and Gen. Extreme Value on the incline. Then at the second observation post the best distribution model obtained was Pert on the descent, while on the ascent the Johnson SB distribution model was obtained. For the distribution model on Sunday, at the first post the Johnson SB model was obtained for the descent, and the Wakeby model on the ascent. Then at the second post the Power Function distribution model was obtained on the descent, and the Wakeby model on the ascent.

Abstract

Good highway construction depends on one factor, namely aggregate quality. Cubic, flaky and elongated aggregates are usually obtained from crushing large stones with a stone crusher. Cubic aggregates are the best form for their use because they have many sides to bind each other. This study aims to see the effect of using flat aggregates on flexible pavements of highways. This study uses a mixture of Hot Rolled Sheet Wearing Course (HRS-WC). This study compares standard mixtures that meet specifications (coarse aggregates using 10% flat aggregates) with several combinations of flat aggregate use in coarse aggregates. From the results of this study, the percentage of safe use of flat aggregates is 13.33%, which if the use of flat aggregates exceeds this value, the marshall parameters obtained are no longer in accordance with the specifications of the HRS-WC mixture.

Abstract

The Construction Industry is one of the sectors that has a strategic role in the development of information and technology in a country. There are various innovations in the construction industry, one of the most promising digital solutions in the construction sector is Building Information Modeling (BIM). Over time, the use of BIM alone in the construction industry is still considered inadequate to achieve the desired target, especially in the supervision of construction projects. Therefore, a new innovation was created by collaborating or utilizing existing technology, one of which is using Augmented Reality (AR) technology. In this study, 3D and 4D BIM modeling was carried out using Autodesk Revit, Ms. Project & Navisworks, and 5D software for project cost estimation, then demonstrating the model with Gamma AR software. Building modeling was carried out using Autodesk Revit software, then from the modeling the volume of work was calculated which would later be used to calculate the project budget. Furthermore, the model was integrated using the project plan schedule with Ms. Project & Navisworks software. Furthermore, modeling is demonstrated using Augmented Reality (AR) technology with Gamma AR software. The results of this study are in the form of 3D BIM modeling in the form of Autodesk Revit software and real-time presentation in the form of Augmented Reality (AR), then 4D BIM in the form of project scheduling that can display work progress using Augmented Reality (AR), then 5D BIM in the form of a project cost estimate of Rp 5,850,593,000.00 which is obtained from the results of multiplying the volume of work by the HSP of Padang City.
