Division 9 - Finishes 9.01 Wall Design and Finishes

A.   Sound abatement is an important consideration in the design of
     a project.  The wall design of the facility must ensure that
     all offices, classrooms, and labs will be insulated from
     unreasonable outside sources of noise.  Mechanical and
     electrical rooms, and other major noise and vibration sources,
     (including noise generated by vehicular traffic) should be
     separated from spaces that would be sensitive to such
     intrusion.  Whenever possible, walls should extend to the slab
     above, other interstitial spaces should be closed, and
     penetration of utilities should be sealed to provide the
     desired acoustic isolation.  The HVAC system should use ducted
     returns.  Relative to sound attenuation, plenum returns are
     undesirable.  Mechanical and electrical rooms are to be
     constructed of masonry walls with slab-to-slab construction.

     In addition, anticipated noise levels that will be generated
     by equipment and occupants of the building shall be determined
     and sound transmission coefficients (STC's) of walls, floors,
     and other elements of enclosure needed to maintain acceptable
     noise levels shall be specified.  The noise levels within a
     space should not exceed 40 dB for executive offices and
     conference rooms, 45 dB for general offices, 40 dB for
     classrooms, and 55 dB for laboratories.  The minimum Sound
     Transmission Coefficient (STC) levels must be 45 STC between
     offices, 35 STC between a laboratory and adjacent spaces, and
     45 STC between instructional space and all other spaces
     (measurements with doors closed).

B.   It is preferable for  partitions to be full height, floor to
     underside of pad or roof above, in areas requiring security,
     sound isolation and in compliance with code.  Fire-rated walls
     shall be specified in accordance with code requirements.

C.   Durable wall finishes shall be specified to minimize
     maintenance.  Painted drywall is the preferred finish for
     maintenance reasons.  Wall covering is strongly discouraged.

D.   Walls specified to receive wallcovering shall be sealed prior
     to application of wallcovering.  Adhesive used shall be as
     recommended by manufacturer of wallcovering.  Extra materials
     (minimum of 5%) shall be labeled and submitted to customer. 
     Cleaning and maintenance instructions shall also be submitted
     to customer.

E.   Masonry walls with bullnose corners are preferred for academic
     buildings.  Glazed CMU block is recommended for corridor walls
     with coved base and bullnose corners.


F.   Include corner guards on exterior corners in heavy traffic
     areas.

G.   Toilet room walls to have ceramic tile wainscot to a minimum
     height of four feet above finished floor.

9.02 Ceiling Finishes

A.   Acoustical 2' x 2' lay-in ceiling tiles shall be specified for
     all interior areas with the exception of restrooms, special
     use or public spaces.

B.   Non-directional fissured pattern acoustical tile such as Model
     #560-U.S.G. Auratone Fissured (Class A) is preferred.

9.03 Floor Finishes

A.   Durable as well as appropriate floor finishes throughout a
     building are a high priority for maintenance and safety
     reasons.

B.   Interior concrete floor areas, which are scheduled to receive
     paint, shall be painted and sealed with a non-slip epoxy
     finish. Concrete floors shall be cleaned and etched prior to
     painting using muriatic acid as required by manufacturer's
     recommendations.

C.   Resilient tile shall be acceptable for classrooms, offices,
     corridors, administrative areas, departmental/college areas,
     elevator cab interiors, fast food service areas, custodial
     storage rooms, and copy rooms for ease of maintenance. 
     Resilient tile floors shall be cleaned, sealed, and polished
     by the construction contractor in accordance with the
     manufacturers specifications.  Vinyl composition tile shall be
     asbestos free.  For any installation involving existing VAT,
     refer to Section 1, Environmental Health and Safety.

D.   Flex-tuff or equal, entrance and vestibule mats shall be
     installed in all public entrances.

E.   The use of carpet is strongly discouraged except for aisles of
     lecture halls and Dean's/Departmental Chairperson's
     offices/suites.  Provide molded nosing for steps and
     transition strips between carpet and adjacent material when
     carpet is specified.  



     The grade of carpet quality shall be determined by space
     needs.  Specify carpet with the following characteristics, as
     a minimum and unless project requirements dictate otherwise.

     1.   A minimum face weight of 24 ounces per yard of commercial
          quality nylon, type 6.6, solution dyed, with soil
          resistance.

     2.   100% synthetic backing with permanent moisture barrier to
          eliminate absorption (below grade  installations).

     3.   An electrostatic propensity of 1.5 KV or lower,
          anti-static.

     4.   Direct glue down installation using adhesive recommended
          by carpet manufacturer.   Where used, underpad to be
          either hair and jute or synthetic foam.

     5.   Fiber Colorfast.

     6.   10 year warranty on wear and edge ravel  (delamination)
          and color-fastness to light.

     7.   Conform to applicable code for flame/fuel/smoke rating
          requirements in accordance with latest ASTM  requirement.
          Carpet shall meet ADA minimum coefficient of friction of
          .6 for accessible ramps.

     8.   Concrete shall be sealed prior to carpet  installation.

     9.   Discontinued products or end-of-runs are  unacceptable.

     10.  Extra materials (5% or 50 square yards maximum) are
          required for each type and color of carpet specified and
          shall be delivered to the Department of Operations and
          Maintenance.

     11.  Each type of carpet shall be from one dye lot only.

F.   Vinyl or rubber rolled goods are acceptable for elevator cab
     interiors.  Preformed stair treads are preferred for stairs. 
     A diamond pattern provides a more maintainable surface and is
     preferred.

G.   Terrazzo is acceptable for vestibules/entrances/lobbies,
     corridors and food service areas.  Walk-off mats should be
     considered for entrance areas.

H.   Quarry tile with double abrasive grain, is acceptable for food
     preparation areas, serving areas behind counters, laundries,
     and dishwashing areas.  Grout should be sealed.

I.   Wood flooring is acceptable for dance floors, handball courts,
     basketball courts, racquetball courts, gymnasiums, and other
     sports activity areas and also where required for acoustical
     treatment.

J.   Seamless flooring and coved base shall be acceptable for
     animal care facilities and "clean" rooms.

K.   Coved Vinyl or rubber base are acceptable with resilient tile
     and/or carpet.
