Abstract

Value Engineering is a function analysis approach that aims to reduce the cost of production or project. The amount of costs that will be needed both in the planning period and also the implementation and time saving process are sought not to increase the amount of cost itself. Gamil & Alhagar(2020) revealed that there are several impacts of Covid-19 in the construction sector, namely project suspensions, workers who lose their jobs, jobs that exceed the time limit, excessive costs, and financial impacts. Jallow et al (2020) stated the changes that must be made to the infrastructure sector in order to comply with health protocols and remain productive during lockdown. The problem in this study is how much the total cost savings can be obtained after Value Engineering method to the architectural work of the Facilities and Infrastructure Rehabilitation project at the Sungai Gelam Campground in the Hall Building. Through graphs and calculations is, the results of 4 work items with the highest percentage were obtained, namely on wall pair work, roofing work, floor formwork work, and frame, door and window work. At the creative stage, the idea of alternative replacements is given to the same quality, function and quality, but at a lower price. Then the analysis stage carries out the development of a comparison between the alternatives to be obtained. The recommendation stage is the result of the chosen alternative. At the recommendation stage, the result of applying the value engineering method is the Material used for the work of the red Masonry 5x11x22cm amounting to Rp.1,934,368.62 or 9.16% of the initial design cost. For Metal Tile Roofing Work of Rp.7,775,287.18 or 30.27% of the initial design cost. For Aluminum Frame, Door and Window Work, 8mm Glass is Rp.8,360,275 or 20% of the initial design cost. For Ceramic Floor Work measuring 40x40 cm (Plain) of Rp. 12,926,981.30 or 25.26% of the initial design cost. The cost efficiency that can be obtained using Rp. 30,996,912.10 or 6% of Rp. 514,217,599.92,- the total project

Abstract

One piece of infrastructure that has an important role in a road network is a bridge. Bridges are land transportation infrastructure that is useful for continuing roads through existing obstacles such as rivers, so the collapse of a bridge will reduce or hold up traffic, which means disrupting the smooth transportation of people and goods. A bridge is a structure that crosses a river or other traffic barrier, so the collapse of the bridge will reduce or hold back traffic, which as a result will disrupt the comfort of traffic and disrupt economic relations. The purpose of a bridge inspection is to ensure that the bridge is in a safe condition for road users and also to secure the investment value of the bridge. In this thesis, we will discuss the identification of bridge condition checks which are carried out directly by conducting field surveys.

Abstract

The use of heavy equipment in civil engineering, mining and large-scale earthmoving works is almost inevitable. In fact,this tool is a factor that really determines the successful completion of work on time in accordance with the required quality. When compared to human labor using simple conventional equipment such as hoes, shovels, baskets, pounding tools for compaction and so on, using heavy equipment has many advantages that promise benefits. Moreover, if a job requires technical requirements and high precision, then the choice of using heavy equipment is a very appropriate alternative. The advantage of using heavy equipment compared to manual tools is that you can complete construction work more quickly. Apart from optimizing working time, construction costs can also be adjusted. Tool productivity depens on the type of tool, worj method, work area conditions and the time needed to complete a job. So, an analysis of the calculation of the heavy equipment requirements required and an analysis of the implementation time required by each tool is required, taking into account the calculation steps, namely: calculating the production capacity of each heavy equipment in order to obtain the productivity value, so that the number of each tool required can be determined.

Abstract

To improve each quality of 60/70 penetration oil asphalt so that it becomes harder, has a high softening point, is more elastic, has good adhesion and is more durable, it is necessary to add other materials and in this research it was tried with Laston AC-WC using additional materials. liquid natural rubber (latex) This research is expected to determine the characteristics of adding liquid natural rubber to the Optimum Asphalt Content (KAO) based on Marshall parameters, so that it can provide good results for flexible pavements in the future. The aim of this research is to obtain optimum asphalt content values with asphalt percentage variations of 4.5%, 5%, 5.5%, 6%, 6.5%, and 7% from the Marshall Compressive Strength Test results and to obtain content values optimum asphalt with variations in the percentage of liquid natural rubber of 3%, 5%, 7% and 9% from the Marshall Compressive Strength Test results. The research method used was an experiment in the laboratory based on the 2018 Revision 2 Technical Specifications. From this research, the results were that KAO from test results with variations in standard asphalt was 5.9% and KAO from marshall test results with variations in liquid natural rubber content was 4.5%.

Abstract

Currently, the development of innovation regarding concrete mortar mix design technology is being widely researched. The innovation in making mortar is the use of additives. This research aims to determine the effect of adding additives on the workability and compressive strength of mortar. The additive used is a High Performance Superplasticizer with the trademark Sika Viscocrete 8670 MN. The fine aggregate used is ex sand. Batang Hari River. The sand category used is coarse sand, based on ASTM C33. The mortar test object is in the shape of a cube with dimensions of 5x5x5 cm. The test specimens consisted of Normal Mortar (MN), Mortar with 0.6% Sika Viscocrete (MS 0.6%), and Mortar with 1.4% Sika Viscocrete (MS 1.4%). The compressive strength testing method refers to SNI 03-6825-2002 concerning Testing Methods for Compressive Strength of Portland Cement Mortar. The results of testing organic dirt in the coarse sand of the Batanghari River are unwashed sand at number 3, and sand that has been washed and soaked with 3% NaOH at number 2 on the organic plate. The compressive strength test results at 8 hours of MN were 6.97 MPa, MS 0.6% was 6.70 MPa and MS 1.4% was 7.73 MPa. The compressive strength at 1 day of age for MN was 14.68 MPa, MS 0.6% was 16.27 MPa, and MS 1.4% decreased to 14.28 MPa. The compressive strength at 7 days of MN was 19.93 MPa, MS 0.6% was 25.33 MPa, and MS 1.4% was 26.95 MPa. Compressive strength at the age of 28 days, MN's compressive strength value is superior, namely 31.53 MPa, MS 0.6% is 28.72 MPa and MS 1.4% is 28.80 MPa. The research results show that to maintain the workability of mortar mixtures that use high performance superplasticizer additives, it is necessary to reduce water. At 28 days, normal mortar has superior compressive strength compared to mortar that uses high performance superplasticizer as added material.

Abstract

In the implementation of road construction projects, there are often various obstacles that arise due to the risks that occur which result in not achieving the expected performance, quality and achievement of work results. The purpose of this study was to determine the risk factors that affect the implementation of work in the field and to determine the application of risk management in road construction projects. In this study, risk identification, risk analysis and risk response were carried out in the construction of road construction projects, especially road construction in Jambi Province. The research method used was by way of a survey distributing risk factor questionnaires and actions on risk factors to consultants. The assessment method uses a risk matrix assessment sourced from AS/NZS 4360: 2004. From the results of this study, it is found that the risk level for road construction work in Jambi Province is very high risk (very high) of 8%, high risk (High) of 7%, and a moderate risk of (Medium) of 16%.
