Work of this section includes:



.1

Precast concrete paver systems for slab on grade application and for

application on structural concrete slab above heated spaces.


.2

Work of this section shall include the specified

precast concre
te

pavers and all accessory materials required for complete and proper
installation of the pavers system shown on the drawings.


1.2

Quality Assurance


.1

Installer Qualifications: engage an installer who has successfully

completed within the last 3 yea
rs at least 3 concrete paver
applications similar in type and size to that of this project.


.2

Field Constructed Mock
-
up: Prior to beginning production work,

construct a mock
-
up approximately 4’ x 4’ for approval by Architect.
Mock
-
up may be located so

as to be incorporated in the work after
approval. Mock
-
up shall be located above a heated space and shall
include the specified waterproofing membrane and the precast paver
system.

Submittals


.1

Shop Drawings: Submit showing all components require
d for paver

application required. Shop drawings shall include plan drawings
showing layout of all paver areas and detail drawings showing how
the various components of the systems fit together. Include
manufacturer’s literature completely describing all

components of the
paver systems and giving detailed installation recommendations and
instructions.


.2

Submit samples made up of actual precast pavers for type, color and

texture required. Include in set of samples the full range of exposed
color and te
xture to be expected in the completed work.


1.4
