Event Schedule

What you will learn

Become familiar with basic electrical quantities of voltage, power, amperage related to electrical estimating concepts.

Read electrical blueprints.

Know how electrical quantities are measured and priced in commercial and public projects.

Price and negotiate electrical scope of work.

About this Course

Electrical estimators estimate the cost of building and engineering electrical and special systems including power, electrical outlets, lighting, communication systems, fire alarm systems and security systems. They are hired by specialty electrical contractors, project managers, estimating organizations, and owner organizations. Some work as independent estimators providing their services to estimating firms, and project managers.

In this training, we provide participants and trainees with fundamentals and concepts in electrical estimating. We provide them with the tools, systems, and techniques to estimate and price electrical and special systems in commercial and public projects.

Prerequisite

None

Technical Requirements

Access to computer with internet access

Who Should Attend

Anyone interested in becoming an electrical estimator.

General construction estimators who want to deepen their understanding of electrical work.

Engineers, managers, and other professionals who are responsible for managing the electrical scope of work.

Course Details

Module 1- Introduction to Electrical and Special Systems Estimating

In this module, participants will be introduced to electrical estimating and thorough understanding of the electrical estimator’s scope of work in building and civil engineering projects. They will be introduced to basic electrical calculations, the relationships between power, voltage, amperage, and how they influence cable and conduit sizes. Participants will also be introduced to NEC.

Module 2: -Electrical Drawing and Documentation

In this module, participants will learn how to read electrical drawings and blueprints. They will also learn how to segment electrical and special systems work, and be introduced to cost breakdown structures in electrical estimating (Uniformat and the Master Format Electrical Divisions)

Module 3: -The Electrical Single Line Diagram

The Single Line Diagram is a representation of an electrical system including major electrical equipment, feeders, and major boxes in an electrical system. Participants will learn how to read and take-off the single line items including switch gears and major feeders.

Module 4: Branch Circuits, Outlets, and Electrical Circuits

Branch circuits and outlets in electrical systems deal with all the wiring and outlets found in building construction. Participants will learn how to measure branch circuits, including systems grounding, equipment connection, lighting, and other outlets in electrical systems.

Module 5. Special Systems

Special systems include communication systems and fire alarm systems. Participants will learn how to quantify and measure low voltage cables and equipment that make special systems including communications, electronic safety and security, access Control, and fire detection and alarm.

Module 6: Pricing Electrical Work

The NECA productivity manual is widely used in pricing and negotiating electrical work. Participants will be introduced to the NECA productivity manual and how to apply that in pricing and negotiating electrical work. We will explore electrical wages including that from unions and prevailing wages and the required crew mix for electrical work.
