Division 9 — Construction Specifications
Legacy Playground at Labine Park
As Amended per Addendum # 2 issued March 24, 2016
ITEM ‘E’ — PROTECTIVE SURFACING (POURED-IN PLACE RUBBER)
A. SCOPE
This work shall consist of installation of a protective surface material at the location(s) shown
on the layout plan per the detail of the plan set provided or as ordered by the Engineer.
B. MATERIALS AND CONSTRUCTION
The Contractor shall supply all labor, materials, equipment and transportation necessary for the
required work. The depth of material may vary based on the fall height of the adjacent
playground equipment and shall consist of a poured-in-place rubber system.
Subgrade shall be crushed stone 6” thick and comply with the manufacturers specifications for
gradation and density. Manufacturer’s specifications are included with this document.
The Contractor shall hire a materials testing contractor to test the crushed stone subgrade. The
testing contractor shall be approved by the City. Testing will be for density (Proctor Test and
Nuclear Gauge Test) and Gradation (Sieve Analysis). The Sieve Analysis and Proctor Tests shall
be completed and acceptable to the City prior to placement of crushed stone. On site density
testing (Nuclear Gauge) will be required after the crushed stone has been placed and before
the poured in place surface has been installed. A minimum of 2 nuclear gauge density readings
shall be taken for every piece of playground equipment with a rubberized surface. Total
readings shall be no less than 20. Failing test results will be subject to material replacement or
other corrective actions deemed acceptable to the City.
