In Chicago, every new building construction or remodeling project must have a design concept made by the building owner based on which the designer or architect can produce a set of building plans. The plans contain all the needed information which the Chicago inspection authority approves after which the construction or remodeling begins. Since all commercial or residential or industrial buildings in Chicago have a number of electrical systems, these plans also need to have an electrical design plan which makes sure the design follows all Chicago building codes.
The New Building Electrical Design Process
Every new building electrical design process goes through several important stages of development. The designer starts the design process by firstly understanding the scope of the project. After that, the designer designs and defines each component ( general office areas, special machinery, power distribution equipment) as per industry standards. After that, the specific parts are arranged together to form the final presentation of the electrical design.
Understanding Project Scope Of New Building Electrical Design
Any new building electrical design has its own unique requirements which depend on the scope of the project. The client's requirements and the structure type of the building determine the scope of the project. While old building renovation just requires the electrical design to fuse the new wiring into the existing wiring system, in case of a new proposed building the scope is much bigger. In this case, an entirely new electrical design is required.
Parts Of A New Building Electrical Design
Depending on the type of project, a new building electrical design can include:
- General electrical requirements (e.g., general purpose repositories)
- Electrical distribution systems
- Lighting systems
- Specialized electrical provisions
General Electrical Requirements
Every new building electrical design must define the general electrical requirements. General electrical requirements are items like 120v receptacle outlets located throughout the building. Although these receptacles are not meant for serving any specific loads they are meant for general use such as wall receptacles, desktops, and electrical equipment which don't have any special electrical requirement.
Specialized Electrical Requirement
Some new building projects may have special electrical types of equipment that need special electrical circuitry which serve only these types of equipment. These equipments can be:
- Vending Machines
- Network Servers
- Microwave Ovens
Due to their load requirements defined by the manufactures, these types of equipment may need individual wiring or dedicated grounding methods.
The complexity of the lighting systems makes them require the greatest development time while developing a new building electrical design.
All lighting fixtures and their controls are included in these systems. As per Chicago codes, these lighting systems require very detailed requirements and need documentation showing they follow the energy-saving technologies.
Electrical Distribution System
The electrical distribution system provides distribution of electrical wiring throughout the building facility. The EDS includes the main switchboard which receives power from the utility and the associated segments like panelboards which distributes all necessary branch circuits throughout the facility. Designing the electrical distribution system also includes measuring the building's amperage load and short-circuit values. These measurements calculate the total electricity demand of the facility based on the single parts of the EDS.
Creating the Electrical Design Plan
The plans should have the references of the design for each device with the appropriate electric symbol. The electrical symbols make recognition of parts easy by people working on the project to make cost estimation and construction easier. American National Standards Institute (ANSI) provides the standardized building plans to be used in building plans.
The building plans for a new building can have the electric design plans included in them as a separate document. In order to make identification of electrical plans easy the pages of the electrical design plan are labeled and number accordingly. They are labeled as E1, E2, E3 and so on. It is important to note that electrical sheets or E sheets are different than architectural E sheets which stand for a paper size. The electrical design plan is usually presented in a specific order:
- Exterior electrical site plan
- Interior electrical power plan
- Interior lighting plan
- Documentation (like electrical calculations,panel schedules, single line diagrams, and energy requirementsof lighting system)
