Project Regulatory Approvals
Field renovation projects typically always require grading and drainage approval from the local jurisdiction
Grading with over 500 cubic yards typically triggers an environmental checklist and a grading permit
Project Regulatory Approvals
Drainage approvals may include: Turbidity monitoring plan during construction Drainage discharge rate control Storm water detention storage Water quality treatmentApproval typically requires plans and calculations prepared by a licensed design professional
Typical Synthetic Turf Selection Process
Form a committee with coaches, trainers, maintenance staff, administration, and user groups
Visit other synthetic turf fields, don’t just look at samples!
Research who you will be manufacturing, installing, and warranting your field

Synthetic Turf Procurement
Work with an independent consultant to prepare specifications for the turf system and the base design
Prepare bid and construction documents to reflect your turf selection criteria
Review budget relative to competitive bid or proprietary product specifications
Contract Administration
Contract development and execution
Bonds and insurance submission
Issue revised CD’s (if required)
CPM Schedule updated
Host pre-construction conference with all contractors and subcontractors.

10. Develop final punch list.
11. Attend final walk through and acceptance with Owner and Contractor or Construction Manager.
12. Secure all guarantees.
On-site observation
Construction Testing of: Sub-grade
Independent 3rd party testing – Owner obligation
Proof roll – visual
