ATTN: Mark Finlinson RE: Park City MARC Locker Room Renovation - Addendum #1

Dear Mark, Please see below for mechanical modifications to the project listed above included in Addendum #1.

I. CHANGES/CLARIFICATIONS TO DRAWINGS:

a. MD101: All the demoed exhaust fan are changed back to existing. Couple of exhaust grilles to be demoed. See sheet MD101.

b. ME101: In an effort to reduce cost and reduce ceiling modifications, the plans have been updated to re-use the exhaust duct mains in areas where the ceilings are indicated to remain. See updated plans showing to re-use these existing exhaust ducts. A couple of new exhaust duct branches have been added in front of the infrared sauna room where the ceilings are still being replaced. Some exhaust cfm requirements have been updated based on what the existing ductwork can accommodate.

See ME101.

c. ME501: Exhaust fan schedule has been updated. Diffuser and Grille schedule has been updated. See ME501.

d. PD101: Some plumbing piping was updated to keep the existing pipe and reduce ceiling replacement. See PD101.

e. PE101: All shower domestic cold and hot water piping has been modified.

Trench drain in front of the men’s and women’s restroom will not be replaced as part of this project. See PE101.

f. PE404: Pipe sizing has been modified at the showers. See PE404.

We appreciate the opportunity to work with you on this project. If you need additional information or have any questions, please do not hesitate to contact our office. Thank you.

Sincerely, Saroj Sapkota WHW Engineering
