Planning and Estimating Flashcards
What is the first step in the electrical planning process?
Conducting a site survey and assessing the project requirements.
What should be included in a detailed electrical plan?
Floor plans, circuit layouts, load calculations, and specifications for materials.
How is the electrical load of a building calculated?
By adding the total wattage of all electrical devices and applying demand factors.
What is a cost estimate in electrical contracting?
An approximation of the total cost to complete an electrical project, including materials, labor, and overhead.
What is the purpose of a bill of materials (BOM) in estimating?
To list all materials and components needed for the project, along with their quantities and costs.
What factors should be considered when estimating labor costs?
The number of hours required, the skill level of workers, and prevailing wage rates.
What is a contingency in project estimating?
An additional amount added to the estimate to cover unexpected costs or changes.
How should overhead costs be factored into an estimate?
By calculating a percentage of the total direct costs to cover general business expenses.
What is the difference between a rough estimate and a detailed estimate?
A rough estimate is a preliminary approximation, while a detailed estimate includes precise calculations and itemized costs.
What role does a project schedule play in planning?
It outlines the timeline for each phase of the project, helping to ensure timely completion.
How can material wastage be minimized in an electrical project?
By accurately measuring and planning material usage and ordering the right quantities.
What is a change order in construction?
A document that outlines modifications to the original contract scope, cost, or schedule.
What should be included in a project bid submission?
The estimated cost, scope of work, timelines, and terms and conditions.
How is profit margin calculated in an estimate?
By determining the desired profit as a percentage of the total estimated costs.
What is value engineering in the context of electrical planning?
A process to optimize the project’s functionality and cost-effectiveness without compromising quality.
How can historical data be used in estimating?
By analyzing past project costs and outcomes to improve accuracy in future estimates.
What is the purpose of a site visit during the planning phase?
To gather accurate information about the project’s conditions and constraints.
How are indirect costs accounted for in an estimate?
By including expenses not directly tied to specific tasks, such as insurance, permits, and administration.
What is a Gantt chart and how is it used in project planning?
A visual tool that illustrates the project timeline, tasks, and milestones.
What is the role of a project manager in electrical contracting?
To oversee the planning, execution, and completion of the project, ensuring it stays on budget and schedule.
How are subcontractor costs incorporated into an estimate?
By obtaining quotes from subcontractors and adding their costs to the overall estimate.
What is a unit price estimate?
An estimate based on the cost per unit of work, such as per linear foot of conduit or per fixture.
Why is it important to obtain multiple quotes for materials?
To ensure competitive pricing and quality for the project’s materials.
What is a scope of work in a project plan?
A detailed description of the tasks and responsibilities involved in completing the project.
