Abstract

The issue currently being faced by the global community is the issue of global warming, which researchers believe is caused by development activities. Currently, every series of development activities has the potential for negative impacts on the environment, so that construction actors need to have awareness and knowledge in minimizing these negative impacts. One solution that can be done by construction actors in building is to apply the concept of Green Building. The writing of this study aims to determine the results of measuring green building criteria based on the Greenship-GBCI standard in buildings by conducting questionnaires and verification interviews. Based on the data collected and the calculations that have been made at the Harper Hotel Building against the 41 Greenship criteria, the building obtained a total of 64 points out of a maximum of 117 points. Thus, the building is considered to have met the criteria as a built building that applies the Green Building concept according to the GBCI assessment tool and has a minimum standard value of rating fulfillment of 58 points for the Gold rating

Abstract

Currently, the construction of toll roads in several regions of Indonesia is being carried out. One of them is the construction of the Tebing Tinggi-Inderapura Toll Road. In this project there are several bridge constructions as a link between roads or as a pedestrian bridge. This bridge uses prestressed beams in which there are steel wires. The steel wire is tensioned by pulling it using a hydraulic jack. When stress is applied, the beam loses its prestressing force. The purpose of this study was to determine the percentage loss of prestressing forces that occurred in the bridge beam. Loss of prestressing force must not exceed the maximum that has been determined. There is some loss of prestressing force which is taken into account. Short-term prestress losses include elastic shortening of the concrete, friction along the tendons and anchor slippage. Furthermore, the loss of long-term prestressing forces is creep in steel, shrinkage in concrete and relaxation of steel. After all the loss of prestressing force is calculated, the total loss of prestressing force is 21.62%. To find out the maximum percentage of loss of prestressing force using calculations from the book Design of Prestressed Concrete Structures by T. Y. Lin H. Burns with the formula Pe/Ac and the value is 8.98 MPa. Where 8.98 MPa is 25%, so 21.62% is smaller than 25%, so it is still safe. In addition, an implementation method for installing girders on bridges is introduced..

Abstract

Seeing the construction work of a complex project, a good project management is needed such as planning, implementing activities, controling activities and scheduling a project.Where a project is said to be successful if the financing/budget is right, quality is right, and on tme. If all three categories have been met, then the project becomes a benchmark for the success of a project. We can see in the contruction of the Medan-Binjai Railroad Which is experiencing problems in the implementation of delays in the work that has been determined by he schedule. Basically, delays can be caused by all parties participating in the operation of the contruction work. In a construction project, it is not always a project that is always on time in achieving success as sheduled. The purpose of this study was to determine the factors that affect the delay in the improvement project for the Medan-Binjai Railway. The method used in data processing n this study are seven factors that greatly affect project delays, including factors due to the Covid-19 virus with a mean value of 3,62, difficulty in accessing project locations with a mean value of 3,59, lack of workforce discipline with a mean value of 3,35, the number of additional jobs wiht a mean value of 3,21, lack of skilled labor with a mean value of 3,15.
