This is a picture of the exterior of a strip mall with several suites. The loading dock on the left is flooded. The left side of the roof over the loading dock, appears to a have a missing downspout, that appears to be contributing to the water in the left side loading dock. There should be a drainage system in the loading dock to keep water dry. Vegetation along the edges of the loading dock area should be removed and the area should repaired to help control possible moisture intrusion into the building.

The article I read was Creating a Team of Expert Consultants for Your Commercial Property Inspection Business. Many commercial inspections require extra consultants or specialists, one person cannot preform, especially electrical inspections because they're not qualified to do them and it is a very dangerous to do it.
The most successful commercial property inspectors should as a project manager. Managing more then one project can only be done by a team of experts to inspect systems that he/she are not qualified to do, and may not be licensed or certified for certain types of commercial inspections.
The successful commercial inspector should have a team of experts picked out for large inspection jobs for clients who want a higher level of certainty about the property.

I selected this image from a jewelry store in Tampa, Florida. The store had a suspended ceiling with access through a back storage room. The picture is of the duct work suspended over the ceiling. There was no issues with the tubing, however there was mold growing on the HVAC vents in the store.

The article that I chose to read for the assignment in the course Inspecting Commercial Electrical Systems Course was Fire Alarm Systems by Nick Gromicko . I chose this as I am not overly familiar with fire alarm systems and will find them in all commercial properties that I inspect. It is good to know that I am not required to be an expert in fire alarms. I did find the article good for providing an overview of things that I can look for and inspect. I will print the article for future reference. Thanks, David Gonzalez, Florida Home Inspector.

The ladder is a necessary tool for any inspection, residential or comercial. I highly recommend a fiberglass multipurpose articulating ladder. You have a multiple size A-frame and extension ladder, with the ability to adjust each side of the A-frame separately to span over a staircase. It allows you to get on a roof, and into an attic in a small package that fits in almost any viehicle.

For this essay I found an article about common types of electrical conductors found in a home. Three types that were mentioned are non-metallic sheathed cable (NM and NMC), Armored cable (AC), and knob-and-tube (KT). NM is the most common also known as Romex has two or more insulated conductors within non-conducting, flame-resistant and moisture-resistant coating. AC also known as BX is very similar to NM, but is covered with a flexible metallic sheathing. KT is typically at least 50 years old, and the most hazardous. This type of wiring should be evaluated/replaced by a qualified electrician.

My Essay.
For inspecting a commercial electrical system course.
In this picture you will see a very old system that is in need of improvements. There are two disconects that have surface rust on the exterior and cabling that is not protected by conduit as well as a sticky note legend.

My Essay.
Inspecting commercial electrical systems course.
This comes from the nachi articles for aluminum wiring.
I found it useful in knowing and understanding how aluminum wiring will break down over time and heat up causing expansion and contraction thus weakening the wire and causing its connections to loosen.

The neutrals and grounds sharing the same bus bar on this panel need to be separated to prevent unintentional energizing of bonded materials such as copper water supply lines. Securing multiple conductors under single lugs can have loose connections which could be a fire hazard.

https://www.nachi.org/baghouse-inspection.htm

Understanding the overall function of a baghouse will give the inspector an understanding of what to look for when inspecting industrial warehouses. Rips, tears, and degraded filters will increase the pollutants that are entering the air. In other applications such as foundry's, these bags are used to collect dust from precious metals to minimize loss.

Air conditioning condensers on top of the warehouse roof in Doral, FL. Units were visually inspected for damage, missing or damaged copper line insulator. Also checked for possible water intrusion at the base where the units are fastened to the roof.

While viewing image labeled 'Commercial 26'. I noticed the roof mounted condenser on the right side of the picture was supported by 4"x4" dimensional lumber. Probably not a very good idea considering the wood will eventually rot and cause the unit to fall and damage the roof causing water intrusion.

Here we can see part of a multi-MVA 34.5KV to 4160V transformer with the feed into the building of the 4160V three phase lines. Each of the three phases has a triplet of cables. The service ampacity is 2000 Amperes.
