COMMERCIAL BUILDINGS OF MULTIPLE TENANTS

Commercial buildings of multiple tenants is our first topic of conversation (Fig. 9.1). This type of building can include a number of uses. Look at the table in Figure 9.1. You can see headings for water closets, lavatories, drink­ing fountains, and bathing fixtures. At first glance, the table seems simple enough, and it is not too difficult. But it can be confusing, so let’s go through some sizing examples.

Подпись: been there done that As a young plumber, I thought the codebook was easy to deal with. Once I started being held responsible for my own code decisions, I found that the presentation of the code was not as clear as I once thought it was. Take some time to work with your codebook before you need it. Learn how to use the information in the code to your best ad-vantage. This is best done with practice. Set yourself up with hypothetical circumstances and use your codebook to solve problems and answer questions. Check with a master plumber, when needed, to see if your solutions are correct. This will make your field work much easier as you come to rely on your code skills. I want you to assume that there will be 62 people rated for the building that we are sizing. How many fixtures of each type will the building require? Take a mo­ment to work the numbers, and then read the following results to see if you arrive at the same number that I do.

if you look under the heading for wa­ter closets, you will see that you need three for men and four for women. Also note the number 3 next to the water closet heading. Refer to Figure 9.2 for an expla­nation of the number. if you look at the number 3 in Figure 9.2, you will see con­ditions for various types of buildings within the general group that we are working with. For example, the statement requires urinals in male restrooms of restaurants, clubs, lounges, and so forth.

How many lavatories are needed in the restroom for women? The correct answer is three. Two lavatories are needed in male restrooms. How many bathing units are required? None, but our building will need a drinking foun­tain. Also note that drinking fountains are required on each floor, so this might increase the number of fixtures needed, depending upon building de­sign. Pay attention to all details and footnotes when you use code charts and tables for sizing.

You probably already have a handle on this type of building, but let’s do one more quick exercise. Using the same type of building, change the occu­pancy number to 125 people. What are the fixture requirements? We need four toilets in the male restroom and five in the female restroom. Two lava­tories are required in the male restroom, and three are needed for the ladies. Drinking fountains are needed in the building. A minimum of two fountains is required.
