If the scope of the work is not clear, always ask questions!
The only dumb question is one that did not get asked.
You cannot prepare a thorough electrical estimate without complete information.
Ask what is to be included by the electrical contractor and what is to be excluded or performed by others.
Here are some questions to consider asking at a job-walk:
• What’s the start date of the project?
• What is the project scheduled date of completion?
• What hours is the work to be performed?
• Is there any over time required?
• Is the owner furnishing any equipment or materials such as lighting fixtures or switch gear?
• During what hours is the work to be performed?
• Who will pay for parking costs of your or your employees' vehicles?
• Who will dispose of demolished (demo) materials?
If information is missing or not clear, by asking questions you will get the answers which will place you on a level playing field with the other bidders.
In other words when you ask questions your competitors will hear the answers and will bid the same scope of work as you.(hopefully!)

Take lots of pictures and videos

Take pictures or write down name plate informationon existing switchboards or power distribution equipment that are associated with your bid.
Example: Manufacturers name, amp rating of main breaker, serial number, amps, volts, and AIC rating.
It is necessary information to have if you have to match new breakers to existing panels or switch gear.
Take pictures of the switch gear as well. Sometimes it is nice to know how many conduits are coming out of the top or bottom of a panel or,
to have an idea of how much clearance there is between panels.
If you are adding circuits, confirm there is circuit breaker space in panels to allow adding circuit breakers.
Lookout for Other Items - Here are some to keep in mind:
1) Are the door openings large enough to get your equipment or man lifts through? Some switchgear or transformers have really large footprints and would not fit thorough a 3'0' door opening. OOPS!
2) How high are the ceilings or roof line of the existing structure?
3) How high of lift equipment or scaffolding is necessary or what size ladders?
4) Does large switch gear have to be installed in the basement or on a floor above ground floor? If so you may have to hire equipment movers to move heavy items
Also be on the lookout for job site conditions that will impact your price.
