1.2       RELATED WORK (BY OTHERS)

            1.2.1     Work related to the installation of the FLOATING CONCRETE JACK-UP FLOOR SYSTEM shall include but not be limited to the following:

1.3       THE SYSTEM

1.3.1.    The FLOATING CONCRETE JACK-UP FLOOR SYSTEM shall incorporate engineered isolators contained within a housing complete with jack-up bolt, perimeter isolation, 2 layers of bond breaker, reinforced concrete and perimeter caulking.

1.4       QUALITY ASSURANCE

1.4.1.    Retain the services of a qualified professional engineer to design the floating floor system.

1.4.2.    The FLOATING CONCRETE JACK-UP FLOOR SYSTEM to be by a proven supplier with not less than 5 years experience in similar specialized  systems. Single source responsibility of the JACK-UP FLOOR SYSTEM is required to ensure continuity and quality of installation. The supplier or their representative shall be responsible to furnish the engineered design, supply the materials and execute the installation. In addition, the supplier is to co-ordinate with other trades that their work has been conducted in accordance with the supplier's recommendations when this work impacts the JACK-UP FLOATING FLOOR SYSTEM.

             1.4.3.    Documents for approval:

The supplier shall submit shop drawings showing isolator placement for the Architects approval prior to commencement of work.

Also to be submitted upon request:

                          -   "quality certificate" showing material compliance with resonant frequency requirements.

-   "quality certificate" showing material compliance with static and dynamic load requirements.

-   "quality certificate" of the isolation material covering the project load requirements.

-       reference list of worldwide projects over a 25 year period.

2.0        PRODUCT/SYSTEM

2.1       APPROVED SUPPLIER

2.1.1.        All products and materials for work in this Section shall be supplied by Vibro-Acoustics as represented by:

2.2        MATERIALS

2.2.1.    Isolation pads: as distributed by Vibro-Acoustics

           Isolation pads shall be nominally 2" thick. Isolation placement to be engineered by supplier but not to exceed 48" o/c.

           The dynamic resonant frequency of the isolation pads shall not exceed 14 Hz at the operating deflection.

2.2.2.    Jack-up housing to be complete with lift bolt used to rain the floating slab. Temporary cap to prevent concrete seepage during pour will be supplied.

Jack-up housing will be designed to incorporate the use of reinforcing bars as recommended by the structural engineer.

2.2.3.    Perimeter Board: Perimeter isolation shall be 1” thick rigid fiberglass board placed on side walls and vertical surfaces to prevent contact with building structure.

2.2.4.    Perimeter Sealant: An acoustical sealant as recommended by the floating concrete floor supplier to be supplied and installed by this Section.

3.0        EXECUTION

3.1        INSTALLAT1ON

3.1.1.    The installation of the Floating Concrete JACK-UP Floor System and materials directly relating to the system will follow the approved procedures of the system supplier and as approved by the architect:

3.1.2.    Before placement of the isolators, as per approved shop drawings, two layers of 6 mil polyethylene shall be installed over the entire surface receiving the floating concrete slab. Two layers will be used to ensure bonding between the floating slab and the structural slab does not occur.

3.1.3.    Reinforcing bars for the floating concrete slab shall be placed and fastened to the housing in accordance with directions from a Structural Engineer.

3.1.4.        After installation of the perimeter isolation and isolator assemblies, the concrete may be poured and must be allowed to cure.

3.1.5.        The lifting bolts are turned in sequence, as per supplier's instructions, until the floor slab reaches the designed height.

3.1.6.        Bolt holes shall be grouted.

3.1.7.     Perimeter and all penetrations shall be caulked.

3.2       FIELD QUALITY CONTROL

3.2.1.    Prior to the start of work by this Section inspect the surfaces which are to receive the floating floor system. Report any  conditions which may be considered detrimental to the performance of the Floating Concrete Floor System

3.2.2.   After the isolator assemblies have been installed by this Section, inspect the installations conducted by other trades: including  (but not limited to) floor drains, floor penetrations (conduits, piping, ductwork etc.) to ensure installation is in accordance  with recommendations of the supplier of the Floating Concrete Floor system. Report any deficiencies for correction.

3.2.3.    Supervise the pouring of the concrete to ensure that the isolator assemblies have not been disturbed in any way that may be detrimental to the performance of the Floating Concrete Floor System.

3.2.4.    On completion submit a signed certificate that the Floating Concrete Floor System has been properly installed.
