HIR Workshop

Objective

The objective of this workshop is to analyze and complete an incomplete house plan with an electrical plan, a plumbing plan, an extra story (floor), a roof, and additional utilities using Autodesk Revit.

Overview

Revit

Autodesk Revit is a Building Information Modeling (BIM) software used by architects, engineers, and contractors to plan, design, construct, and manage building and infrastructure designs. For architects, Revit is used to create floor plans, elevations, and 3D views in addition to rendering and animating the building design. For structural engineers, Revit is used to analyze and evaluate how well a building conforms to building and safety regulations. For mechanical, electrical, and plumbing (MEP) engineers, Revit allows coordination with architects and other engineers to design systems with all the architectural and structural components. For construction professionals, Revit is used to plan and understand construction methods, materials, and schedules.

Plumbing & Electrical Plans

In addition to other technical drawings, architects, engineers, and contractors require plumbing and electrical plans to accurately construct buildings. Plumbing plans show various plumbing fixtures, such as sinks, toilets, and showers, and the pipes connecting these fixtures to water sources and disposal systems. There are three main types of water systems: hot water, cold water, and sanitary water. Hot and cold water systems introduce filtered, ready-to-use water into the plumbing system while sanitary systems remove wastewater from the system and route this water to treatment facilities. Plumbing plans ensure that each component receives the right type of water and has adequate disposal of wastewater.

Electrical plans show the electrical components within a building. These schematics include the electrical circuits within the system. Each electrical circuit is routed to a centralized panel board that houses circuit breakers and fuses, one for each electrical circuit. Electrical plans also show electrical outlets that have two main types: default and ground fault circuit interrupters (GFCI). GFCI outlets are mainly used near water sources as they help prevent water damage to circuits that can cause fatal accidents where current can be inadvertently directed away from the outlet and cause shock. Electrical plans direct the wiring of outlets and other appliances.

LEED Accreditation

Leadership in Energy and Environmental Design (LEED) is an internationally used green building certification program developed by the U.S. Green Building Council. To receive LEED certification, building projects must satisfy prerequisites and earn points to achieve different levels of certification. The different categories for the LEED checklist correspond to principles of design, construction, and maintenance. The eight LEED categories with brief descriptions are:

Third-Party Revit Components

While Revit has a wide range of components, additional components can be downloaded from third-party websites and imported into existing Revit files. Common third-party websites include BIMObject, BIMSmith, and RevitCity. These websites are continuously updated with new components. Making an account with one of these sites will be extremely beneficial in the completion of both your project and this workshop.

Materials and Equipment

• Autodesk Revit 2025 or newer

Procedure

In this workshop, an electrical plan, a plumbing plan, designing and connecting multiple floors, and designing a roof will be completed. An incomplete two-floor house plan is provided to explore these skills. Download the incomplete two-floor house plan RVT file here. To avoid compatibility issues, use Autodesk Revit 2025 or a newer version. The file that is attached above is a .zip file. To extract the files you must download it, click on the folder once, then at the top ribbon click “Extract”. From there you will be able to open the relevant files to complete this workshop.

Plumbing Plan

In this part, a plumbing plan will be created for one bathroom on the first floor. Understanding the implementation of a plumbing plan will be important for the completion of Benchmark B for the Housing in Revit (HIR) semester-long design project (SLDP).

1. Open the file above.
2. In Hover the mouse over the design and left-click once a blue box surrounds the design. This will highlight every element in the design (Figure 1).
