Abstract

Construction projects often suffer from poor performance in terms of execution time management. This is a problem that must be taken seriously. When a delay occurs in a project, there will be additional costs that must be incurred outside the contract and can cause losses for the parties involved, especially the construction contractor. Therefore, it is necessary to pay more attention to the delay in implementation time. The research method used in this research is descriptive quantitative by determining the research variables based on previous journals. Supported by the distribution of phase 1 questionnaires and phase 2 questionnaires which were distributed to 40 respondents related to the Facility Workshop development project located in Melak, East Kalimantan. The questionnaire analysis was assisted by the SPSS version 25 program. The analyzes used were Validity Test, Reality Test, Descriptive Statistical Analysis, Normality Test, Multiple Regression Test, T Test and F Test. From this study, the factors causing delays based on descriptive statistical analysis that meet the requirements of the T-test are material factors (X1), with the indicator "Incorrect material delivery schedule (X1.2)" then supported by the results of multiple linear regression analysis with coefficient positive regression, meaning that there is a significant effect between variables and project delays.

Abstract

To save energy, according to two aspects of the Sustainable Development Goals (SDGs), namely Sustainable Urban Development (SDG 11) and Climate Change (SDG 13), concrete efforts that can be made are increasing energy efficiency and conservation, reducing greenhouse gas emissions, and strengthening resource sustainability. One of the initial efforts that can be made to increase energy efficiency and conservation is by applying Building Information Modeling (BIM) for energy simulation in building structures. One of the BIM-supporting software that can be used in energy simulations is Autodesk Revit, which functions for architectural, structural, mechanical, electrical, and plumbing (MEP) modeling, and Autodesk Green Building Studio, which is a cloud-based media for conducting simple simulations of building performance so that various aspects of its energy can be analyzed for assessment. The Green Building aspect assessment of GBCI used is the GREENSHIP Existing Building Ver1.1 parameter, taken from the Energy Efficiency and Conservation (EEC) aspect, which is a quantitative assessment and can be modeled. The results of the EEC aspect assessment using a quantitative assessment tool obtained a value of 5 points from a total maximum value of 28 points. This value indicates that the 1 Park Residence Building is a building that has not implemented Green Building and requires actions that support the sustainability aspect of the building.
