Special Conditions – Add Clause 29 Landscaping and Aftercare

Clause 29 is added:

and locations for equipment and materials storage at appropriate times, as required to facilitate this work. Some specifics are provided here:

Athletic Field Lighting Installation. The park contractor will install all of the conduit to within two feet of the light pole and building locations, and shall plug and mark the locations of each conduit terminus. The lighting contractor will be responsible for supplying and installing the athletic field foundations, poles and fixtures, and panel installation and wiring, testing and commissioning.

Playground Installation. The park contractor will be responsible for grading the playground vicinity to subgrade. A grade tolerance and compaction test must be performed to demonstrate conformance to the specifications prior to the playground contractor beginning installation. Once the subgrade has been verified, the playground contractor will install the equipment. The park contractor shall then install the concrete edging and accessibility ramps after the playground equipment is installed. When that work is complete, the playground contractor will return to install the underdrain and mulch.

Synthetic Turf Field Installation. The park contractor is responsible for providing the stone base for the synthetic turf, which will be independently tested by FieldTurf for acceptance prior to installation of the synthetic turf.

Water Quality Monitoring. To meet the requirements of the Final Water Quality plan, which is included in the Appendix, M-NCPPC will have an agent to perform the required monitoring during the construction period, as defined on Pg 7 of 8 in the report. The contractor will need to facilitate this work. These efforts will include, but not be limited to:

o Facilitate the equipment installation, maintenance and sample collection for the testing at Sediment Basin No. 1, as shown on C-302. Make adjustments as needed to the sediment trap inflow arrangement to maintain a central inflow point and allow for proper functioning of the sediment sampling equipment, which is located at the inflow and outfall to the basin.

o Provide access for the data collection.

o Provide other coordination and work required to achieve the goals of the water quality monitoring plan not explicitly stated here.

29. LANDSCAPING AND AFTERCARE

The landscaping and aftercare technical specifications are unique to this project. The Contractor may install plant materials throughout the construction period and is required to provide aftercare of the planted materials until completion and acceptance of all punch list items for the project.

As outlined in the technical specifications, the M-NCPPC Construction Manager will conduct a final inspection of all plant materials at the time of punch list completion to ensure compliance with Plant Installation specifications (Section 722). Once the Contractor has completed all necessary work to meet the specification requirements to the M-NCPPC Construction Manager’s satisfaction, there is no additional warranty period or aftercare required.

__________________________________________________________________________________


January 2014 607-3

ASTM - F 569, cold rolled steel pipe for framework (SS 40)

ASTM - A 500, Grade B, steel square sections

ASTM - A 123, hot dip galvanizing

ASTM - F 1043, protective coatings

607.07 CONSTRUCTION

A. Fence lines specified in the Contract Documents are only guides. The exact location

of the fence will be determined in the field by M-NCPPC Construction Manager.

B. Install all posts plumb. Maintain, as uniform as practicable, the spacing specified.

C. Use post lengths that accommodate the fabricated width of the fence fabric without

stretching or compressing the fabric and that provide the required spacing below the

bottom of the fabric.

D. Install terminal posts at all ends, abrupt changes in grade, and as changes in

horizontal alignment greater than 15 degrees.

E. Install post caps on all round line, terminal, and corner posts.

F. Run a tension wire or rail continuously between terminal posts near the top and

bottom of the fabric (see details). Attach the tension wire to the fabric with hog ring

fasteners at 18 inch intervals.

G. Tie the fabric to the brace rails at intervals not exceeding 2 feet and to posts at

intervals not exceeding 12 inches. Attach stretcher bars to terminal posts by

connectors equally spaced at not more than 16 inch centers. Place top and bottom

connectors as close as possible to the ends of the fabric.

H. Anchorage for line posts and terminal posts: Where rock is encountered at a depth

less than that specified for the footing, drill a hole 1 inch larger than the greatest

dimension of the post to a depth of 12 inches or the planned footing depth, whichever

is less. After the post has been set, fill the remainder of the drilled hole with a non-

shrink grout as approved by the M-NCPPC Construction Manager. Fill the space

above the rock with concrete.
