My prices may be dated. Choices are:

1 Poured epoxy floor installtion cost is fairly fixed material cist depends on thickness (10 to 120 mils). A 40 mil floor will fill in the "milling" necessary to prepare the floor. This will runs about $3 a square installed in the US. Suppliers are:

2 Tile floor costs $5 a square installed and it lasts forever. Suppliers are:

3 Carpet tile costs about $8 a square installed, lasts forever, can be moved, and is very quiet. Two suppliers are:

5 Laminate sheet cost about $3 a square installed, lasts forever, and can be moved. Desco Industries 909.598.2753 is the only suppler I know.

Centimark 412.444.4585 Mark Harrison Static Control Products 800.356.2728 fax2729

7 Floor polish is cheap to install, doesn't last long in traffic areas, and is difficult to monitor. Suppliers are:

Go with the carpet tiles. They damp all the noises in the factory so you can speak at normal decibles, talk on the telephone without asking the other party to yell at you, and are lots more comfortable to work on, reducing operator fatigue.

Now, these seem like small, unquantifiable benefits for the premium you pay, but if you are just setting up a factory, it's a lot easier to go with the carpet up front than to try to justify it in two years.

IT'S WORTH EVERY CENT. You won't see all your operators sitting down near the end of the shift. And you won't be in your cube, either!
