City of Nashua, Public Works Division
Board of Public Works Meeting Date: November 21, 2016
Stephen Dookran, P.E., City Engineer
Engineering Department
Henri Burque Pedestrian Bridge
Engineering Services
To approve the contract for engineering services for repairs to the Henri Burque
Pedestrian Bridge to CLD Consulting Engineers of Manchester, NH in the amount of
$17,107. Funding will be through Department: 160 Admin/Engineering; Fund:
Capital; Activity: Bridge Rehabilitation.
The Henri Burque Pedestrian Bridge provides connectivity from the Pennichuck Middle
School to surrounding neighborhoods east of the school. Routine inspections by the
NHDOT stated the deck has a rating of 6 (satisfactory) and the superstructure has a
rating pf 7 (good). However, the substructure has a rating of 3 (serious) primarily due to
the deterioration of the pier caps at the point where it sustains the bridge bearing pads
over which the steel superstructure rests. The nature of the distresses requires
specialized technical expertise in bridge repairs. Engineering has negotiated a contract
for $17,107 with CLD Consulting Engineers of Manchester, NH, who recently provided
engineering services for the Manchester Street Bridge project, to provide the design for
bridge repairs. This includes development of the specialized detailed drawings and
contract documents, bidding assistance and construction engineering. Sole servicing
these services to CLD is preferred because of CLD’s experience with various bridges
and retaining walls in the city as well as their fee rates are reasonable.
Pending approvals, design would be carried on during the winter with construction
repairs in the spring.
