Request for Qualifications #43-19
Replacement of the Maplewood Avenue Bridge over North Mill Pond
NHDOT Bridge #231/103
Purpose and Background
In 2018, the City of Portsmouth began a citywide bridge evaluation and improvement master
plan. This effort identified the Maplewood Avenue Bridge over North Mill Pond as nearing the
end of its design life. The City has elected to move forward with selection of an engineering
consultant for bridge design engineering and permitting services for the replacement of this
bridge.
The existing bridge was constructed in 1940 and consists of a single masonry arch bounded by
200 feet of seawall to the north and 313 feet to the south. In 1976 the arch was lined with a
corrugated metal plate arch. The liner was grouted into place and rests on concrete footings.
The total span length of the arch is 25 feet. Maplewood Avenue carries two lanes of traffic over
a 32’ wide pavement section with granite curbing, 6 foot concrete sidewalks, and guard rail on
either side. The bridge carries water, sewer, and gas mains in addition to overhead utilities. This
stretch of road sees an approximate average annual daily traffic volume of 10,000 vehicles per
day.
The pertinent section of the draft 2018 City-Wide Bridge Evaluation Report is attached for
additional reference (see Appendix A).

Selection Process
The City of Portsmouth intends to proceed with a consultant selection utilizing a Qualifications
Based Selection (QBS) process in accordance with the NHDOT Municipal Bridge Aid Program.
A technical proposal including a project understanding and project approach is not required at this
time and will not be reviewed if submitted. The City will rank interested firms based on
qualifications and experience only.
Upon receipt and review of all qualifications, the City’s review committee may then choose to
interview firms or make a selection based solely on qualifications. The City will then enter into
negotiations with the top rated firm for a fee for services. If the City cannot reach agreement on a
scope and fee with that firm, the City will begin negotiations with the second rated firm, and so
on, until an agreement is reached.
The City reserves the right to negotiate additional scope of services with the selected firm.

Priority: 3
Introduction
The existing bridge was constructed in 1940 and,
and according to NHDOT records, rehabilitated in
1976. The structure consists of a single masonry
arch with a grouted corrugated metal plate arch
(CMPA) liner founded on concrete footings. The
1976 rehabilitation consisted of the installation of
the CMPA liner and construction of the concrete
footings. The bridge has a total span length of
West Elevation
T in both approaches.
25’ and carries two lanes of traffic on a 32’ wide
paved roadway. A 5’-11” wide sidewalk is located
on the west side of the bridge and a 6’-8”
sidewalk is located on the east. The bridge has
an ‘E2’ load restriction, and posting signs
properly identifying this restriction are installed
F According to the latest NHDOT Bridge Inspection Report, the condition rating of the culvert is
a 3, or ‘serious’, and has an AASHTO sufficiency rating of 43%. The bridge rail, rail transition,
bridge rail approach, and approach rail ends are substandard. The bridge is listed on the
NHDOT Municipal Bridge Redlist.
A For the purpose of this report, upstream is considered south for this bridge.
Observations
RThe pavement is in poor condition with cracking,
settlement, and potholes throughout the
D approaches and on the bridge; pavement repairs
have been completed in several locations. There
is poor stormwater drainage at the bridge as
evidenced by ponding on the west side and
vegetation growth on and around the curbs. The
sidewalks are rotating towards the road with
significant settlement along both the west and
east curb lines at the north and south ends. This
Northeast Seawall
settlement/rotation creates uneven walking
surfaces on the sidewalk (i.e. tripping hazards). A
section of the vertical granite curb is missing on the east side. The rail system, though
substandard, is in good condition with minor plow damage.
On the east side of the bridge there is an exposed out-of-service sewer main that is severely
deteriorated with extensive cracking and complete section loss along the invert. An active
