Braintree, MA in the amount of $150,000.00. Funding will be through
Department: 160 Admin/Engineering; Fund: General; Activity Description:
Multi-Years Paving.

Stantec has been surveying the conditions of street pavement in the city and
updating the database. They recommend that more crack sealing be done in order
to keep up with the original goals of the program. Cracksealing as much done
prior to winter setting will be more beneficial. Streets will be chosen from
Stantec’s updated list. We are requesting a change order to the existing 2017
Pavement Preservation Maintenance Program.

The 2017 Pavement Preservation Maintenance Program, in the amount of
$327.423.94, was awarded to Sealcoating, Inc. of Braintree, MA in June 2017.
These streets that will be chosen for crack sealing will be from PCI Band#2 (93 —
87 PCI, which require routine maintenance. This will extend life of these streets
and maintain PCls in this range.

The total value of Change Order No. 1 is $150,000.00. With Change Order No. 1,
the total contract value is $477,423.94.

Main Street Vehicle Detection at Allds Street

To approve the contract with Electric Light in the amount of $17,880 for the
installation video vehicle detection at the intersection of Allds Street and Main
Street. Funding will be through Department: 161 Streets; Fund: General;
Activity: Street Infrastructure Improvements ($4,174) and Department: 161
Streets; Fund: Paving Trust; Account Category 81 - Infrastructure Improvements
($13,706).

Electric Light Company Quote

In preparation for the paving of Main St south of Allds St, the traffic detection loops
were cut by the milling operation and work being done by Pennichuck Water Works.
Pennichuck Water Works is contributing their share of the replacement cost to the
paving account since the paving project will replace all the loops at the same time.

Rather than replace the underground loops at a cost of $13,706, the City views this as
an opportunity to install above ground vehicle detection in the form of video cameras
at a cost of $17,880. The underground loops are constantly damaged or cut through
sometimes by snow plows or just wear and tear. Above ground detection avoids many
of the impacts associated with construction activities in the roadway.

Electric Light Company submitted a quote to perform the work at a cost of $17,880
(attached). They have recently installed several cameras along Daniel Webster
Highway in Nashua under similar circumstances where putting back loops was less
feasible. This will be paid for by the paving account ($13,706) and the DPW
infrastructure account ($4,174). Electric Light has done reputable work over the last
several years for the City of Nashua on several similar traffic signal improvement
projects. They have also been very competitive with their pricing.
