Generative Design for Construction Site Layout Planning

Raj Pradip Birewar (10664183) 07 May 2021 (has links)
<p>The construction industry contributes significantly to the GDP of the United States, attributing to its growth at an unprecedented rate. Efficient planning on all stages of construction is the only way to combat dynamic obstructions and deliver projects on time. The first element involved in the planning phase deals with the layout of the Construction Site. It significantly regulates the pace at which construction operations function and directly affects the time, cost, and safety linked to the successful delivery of the target project. Hence, it is paramount to ensure that every component of the construction site maneuvers with the utmost productivity. One such equipment that occupies significant attention while carrying out the CSLP process is Tower Crane. Tower crane optimization is pivotal to ensure proper lifting and handling of materials, and warrant conflict-free work zones. This research, therefore, aims to optimize its position by maximizing the lift ability. To achieve the goals, Generative Design- a paradigm that integrates the constructive features of mathematical and visual optimization techniques, is used to develop a relatively comprehensible prototype. The first part of the research, thus, utilized Generative Design on two construction sites- one from the United States and one from India. After implementing the visual programming algorithm, an improvement of 40% was warranted in the lift score. A pool of potential alternatives was explored and supplemented by the trade-off illustrations. The concept of trade-off was substantiated by allowing a framework for prioritization of lift cycles, and facilitating a holistic decision-making process. To evaluate the usability, 12 participants were chosen based on their previous experience with tower crane operations. The participants witnessed a live demonstration of the algorithm, answered a Likert scale questionnaire, and appeared for an open-ended interview to provide feedback about the proposed Generative Design technique. After carrying out narrative analysis for the usability aspect- it has been unanimously observed that the technique has extreme efficiency of usage and can evidently prevent the occurrence of errors. The study concludes by providing recommendations to augment the significance and usability of Generative Design for tower crane position optimization. </p><br>

Parameterstyrd projektering av broar : Koppling mellan Rhinoceros-Grasshopper och Tekla Structures / Parametric design of bridges : Connection between Rhinoceros-Grasshopper and Tekla Structures

Abed, Mohamad Samir, Hosseinzade, Azita January 2017 (has links)
I byggbranschen har nya metoder för projektering utvecklats genom införandet av moderna och mer kraftfulla BIM-verktyg. Flera av dagens konstruktioner modelleras enligt tredimensionella principer.Tekla Structures är ett kraftfullt BIM-verktyg som klarar av att hantera både huskonstruktioner och anläggningskonstruktioner. Trots detta kan programmet inte hantera broar med dubbelkrökning på ett effektivt sätt. Projektörer behöver därför utgå från flera program för att kunna hantera komplexa brokonstruktioner.För att kunna utnyttja fördelar med Tekla Structures, behöver programmet att utvecklas eller kompletteras med andra tredjepartsprogram. Detta projekt syftar till att integrera nya arbetssätt och införa en metodik, i form av parametriserade modellering i Tekla Structures. En sådan form av modellering tillåter användaren att modifiera parametrar för en önskad modell.Ett skript är skapad genom ett visuellt programmeringstillägg, som genererar parametriskbaserade bromodeller. Brokonstruktionstyp som modellerades i detta projekt är en plattrambro.Resultatet av projektet pekar mot att parametriserad modellering är ett effektivt sätt att modellera och en lösning för att bland annat hantera broar med dubbelkrökningar. / New methods for project designing in the building construction industry have been developed by introducing modern and powerful BIM tools. Several of today’s constructions are designed according to three-dimensional principles.Tekla Structures is a powerful BIM tool that is capable of managing both house and infrastructure constructions. Despite this, the program cannot handle bridges with a horizontal and vertical curvature efficiently. The designers must instead rely on several other applications to manage complex bridge constructions.In order to use the advantages of Tekla Structures, the software needs to be evolved or complimented by other third party softwares. This project aims to integrate new working technics and introduce a method based on parametric design in Tekla Structures. Such form of modeling enables the modification of parameters to a desired model for the user.A script is created through a visual programming extension that generates a parametric based bridge models. The bridge type in this project was designed, is an integral bridge.The project has proved that parametric based design is more effectively and a solution to manage bridges with horizontal and vertical curvature.
