Commercial Air Duct Cleaning Projects

Approximating business air duct cleaning jobs is different from approximating and pricing residential jobs. You can not count the number of vents or pass the square video footage of the building to approximate industrial projects. There is such a wide range of HVAC system types that an easy size fits all approximating method will certainly not function.

A convenient estimating plan/process needs to have the ability to deal with the wide variety of HVAC systems as well as parts found in today’s industrial buildings. Plus, you have to have a mutual understanding of the various parts that you will come across because each of these parts can supply its very own unique cleaning challenges. Your objective is to have a precise and repeatable estimating procedure so you can win a lot more jobs on a regular basis. Let’s take a look at the basic steps:

1. Testimonial and recognize the cleansing specification.

A lot of industrial jobs have a cleansing specification that tells you what requires to be cleaned, the degree of cleanliness that should be achieved, paperwork requirements, and so on. Cleaning up specs are figured out by the project designer or environmental specialist. The National Air Duct Cleaners Association (NADCA) cleansing specification is the basis for a lot of these specifications.

You must check out and also comprehend the cleansing spec if you are posting likely to prepare a correct proposal. If you have questions on a cleaning specification make certain to call the designer for an explanation. If there is no cleansing spec you can aid the structure proprietor by supplying one. The cleansing spec that you provide will certainly include products as well as needs that can prefer your companies’ capacities and offer you a bidding advantage.

2. Review and also recognize the mechanical blueprints.

Obtain a collection of blueprints for the project. You will certainly need to recognize how to read plans. Huge jobs can have many web pages of blueprints that can be very tough. The best method to technique something similar to this is to take a look at one air handler and also its associated ductwork at once. The mechanical prints can also have essential details about the scope of the duct cleansing demands as well as a routine of units. All of this information is extremely crucial due to the fact that it aids you to understand the heating and cooling system you are approximating.

3. Do a go-through of the job.

This will certainly aid you to understand the project as well as let you see anything that will certainly influence access to the cleansing of the cooling and heating system. Ease of access to the HVAC system and also parts will certainly help determine the production rate you will certainly utilize. Excellent accessibility usually means a quicker manufacturing price and also bad availability implies a slower manufacturing rate.

4. Do a takeoff of the HVAC system.

After you have checked out as well as got a mutual understanding of the mechanical plans and also have done a go through of the task you are ready to begin dealing with your quote. Based on the blueprints, you break down the HVAC system right into its part and locate the number of each element you have. For example:

– a variety of air trainers

– straight feet of supply duct

– linear feet of the return ductwork

– number of grills and registers

– number of VAV boxes

– number of coils

– etc.

It is really helpful to use various color markers to color in the various parts of the blueprint. Then it is simpler to count the number of each component and also get in that number on your take-off sheet. Also, you are much less most likely to miss out on something if you are coloring in each element.

5. Determining the variety of guy hrs called for.

When the take-off is complete, you determine the number of man-hours required to clean up each element. For instance:

– 2 air handlers at 6 man hrs each = 12 guy hours

– 500 square feet of ductwork at 15 feet per man-hour = 33 man hrs, etc.

You after that include all the man hrs for each and every component to get the complete guy hours for the project.

6. Establishing the cost per man hr

As soon as you have actually identified your complete man-hours needed to complete the task you use the labor rate that you will bill your client. As an example: if you have a total amount of 100 guy hrs on the job at $75.00 per guy hour labor rate = $7,500 labor estimate. You will certainly require to bill at least $75.00 per guy hour to have gross profits that range from 40% to 60%. Some parts of the country cost extra as well as some charge much less. You may need to do a little research in your location to determine what an affordable labor rate will certainly be.
