Integration of Augmented Reality to BIM Model

Abstract

This study investigates how to seamlessly incorporate augmented reality (AR) with Building Information Modelling (BIM) and its impact on construction efficiency. By overlaying digital information onto physical environment, AR enhances on-site decision-making and spatial understanding. The project emphasizes the practical benefits, such as improves collaboration, reduced errors, and enhanced project outcomes, positioning the AR-BIM fusion as a key driver for construction excellence.

Introduction

I.  INTRODUCTION

A. BIM

Building information modelling BIM is a process supported by various tools technologies & contracts involving the generation & management of digital representation of physical & functional characteristics of place. BIM can also define as representation of 3D object or any object in digitalisation & visualization format.

B. Augmented Reality in Construction

AR has proved to be quite effective in the building sector as well. Using augmented reality effectively can enhance team collaboration, enable you to win more projects, and even increase safety., AR is having more advantages in construction field, risk of errors & delays reduces, AR also increase safety, reduces risk of accidents and it is more realistic. You can read more about augmented reality’s current and potential applications in building below. Additionally, business using AR effectively will be highlighted so that you can be motivated to continue with your own projects.

II.  LITERATURE REVIEW AND METHODOLOGY

The main methodology includes three steps to approach the augmented reality on physical environment. The steps include Analysis of structure Modelling and detailing and implementation. After successful implementation the model is executed through augmented reality in physical environment. Flow chart of methodology is shown in below flowchart.

A. Structural Analysis

i) Creating a structural model in staad pro using nodes that is calculated from the particular plan. In this example, the 3d frame model is produced using the choose option and structure wizard on the top. Select the frame model from the model type and click on the bare frame option. A new window will appear with the number of bays in length, breadth, and height. Enter the numbers for the number of bays as per the building design and the number of storeys. The values of each bay are then inputted in accordance with the building's plan view, and the model is imported to STAAD software using the structure wizard option.

ii) Applying various loads

After creating a structural model using staad the model is subjected to different loads i.e. live load, dead load, self-weight and all the requirements. After proper analysis of a model the required results like displacement, deflection, shear force, bending moment are obtained.

B. Creating Revit Model

1. Create Walls: Go to the architecture tab, choose a wall, then select the properties toolbar, click on edit type, duplicate, and then ok. Next click on edit, specify the wall's thickness and unconnected height, and then click apply. Include doors, windows, slides and all required components.
2. Designing Roof: Make a roof out of an extrusion or the footprint of the structure. Roofs may be designed in a variety of ways using Revit. Choose the strategy that best meets the requirements of your project design.
3. Create Floors: Choose Architecture. Choose the floor from the built panel, your floor level, the line from the draw panel, a value for the plinth offset, draw the line at the outer boundaries of the wall, and then choose Finish Edit Mode: Choose floor, then properties tool bar, now click on edit type, now choose duplicate, provide duplicate name, click on edit, then choose second row floor thickness, and finally click on ok and again on ok.

C. Details of Building

These are details of building that is given during implementation.

1. Height of the parapet wall - 1m
2. No. of storeys of building - G+1
3. Depth of the slab – 130.mm
4. Inner and outer wall thickness - 4 & 9 inches
5. Height of the floor – 3.5m
6. Depth of footing - 1.2m
7. Footing dimensions -12*12m
8. Plinth beam - 0.3*0.25m
9. Roof beam - 0.3*0.22m
10. Column size - 0.3*0.3m
11. Characteristic & yield strength -M25&Fe500.    

D. Plugin to Augin

Download the augin software into the mobile phone, login to the software using required credentials. Plugin the document to the software which generates a particular QR. Using tablet or smartphone by scanning the QR the augmented reality of the project is clearly visible on site before construction.
