Hazardous Mitigation Grant
To approve the purchase of two Trimble RIO GNSS Network Rovers from Waypoint
Technology Group of Albany, NY in the amount of $54,168.20 Funding will be
through: Department: 169 - Wastewater; Fund: Wastewater, Activity: FEMA Hazard
Mitigation ($46,600); Department: 160 Admin & Engineering; Fund: General; Account
Classification: 61 Supplies & Materials ($2,000.20); Department: 169- Wastewater,
Fund: Wastewater, Activity: Sewer Structures.($5,568).
There is a need for Public Works to first accurately map certain features critical to
operations and then to quickly locate them during times of emergency. These features
include sewer and drain manholes on the interceptors and mains, that run through
properties as well as discharge points along the rivers and streams. These structures
can become covered with vegetative growth and debris making them difficult to find
during times of emergency. Examples of events within the past 18 months where
countless staff and consultant hours were spent trying to locate structures were the
flooding of the North Merrimack River interceptor and the failure of the Northgate
pump station force main.
The City is in receipt of a Hazardous Mitigation Grant and has determined that the best
use of these funds would be for the purchase of survey equipment to aid in locating
and/or recreating our vital infrastructure in the event of an emergency. Aside from the
sewer and drainage structures described above, these mobil GPS units will be used to
quickly locate other infrastructure such as fire hydrants if they become buried under
snow, water, or soil due to various natural disasters as well as re-establishing critical
signs that are displaced. The units will also allow the City to quickly identify various
manholes in close proximity within roadway intersections.
The Trimble R10 GNSS system was selected because it is designed to work more
effectively, no matter how extreme the environment. The new, lighter design is more
balanced, to allow the surveyor to travel farther, faster, and gather data more easily. It
has the advantage over traditional survey equipment in not having to set up in difficult
terrain.
Three quotes for two Trimble R10 GNSS systems were received with results as
follows:
Two Units
Waypoint Technology Group of Albany, NY $54,168.20
Keystone Precision Instruments of Allentown, PA $55,150.75
GPServ, Inc. of Orlando, FL $63,620.00
Waypoint Technology Group is the qualified, low bidder for this purchase.
