SUBJECT: Proposal for Civil Engineering and Surveying Services for
Yavapai County Courthouse Roof Drain Connections
Dear Mr. Otwell:
Kelley-Wise Engineering, Inc. (KWE) is please to provide this proposal for civil engineering services
for the subject project. We understand our work scope would include: 1) conceptual layout; 2)
topographic survey; 3) construction plans and specifications; 4) design report; 5) construction
stalking; and 6) construction inspections. County personnel have discovered that the roof drains may
connect into the sanitary sewer system based on their recent camera work for the sanitary sewer
system. The City of Prescott does not allow storm water runoff to be connected into their sanitary
sewer system. Four roof drains exist – one at each corner of the courthouse building.
Last week we surveyed the flowline elevation of Montezuma Street on the west side of the
courthouse. West of the courthouse building the flowline elevation varies from about 5353.5 sloping
north to about 5351.0. The bathroom floor on the west side of the courthouse is 5358.4. Gravity flow
of the roof drain should be achieved if you can re-plumb these connections within the basement to
exit the building at about elevation 5355.5 (south side) and 5353.0 (north side) or higher. This would
provide about two feet of fall to the gutter flowline in Montezuma Street. Based on this scenario, we
offer the following work scope:
TASK 1: CONCEPTUAL LAYOUT – KWE will develop a conceptual layout for the new roof drain
connections. We anticipate two gravity storm drain connections from the west side of the courthouse
- one connection near each of the northwest and southwest corners of the building. These two pipe
routes would then extend westerly and discharge at the face of curb on the east side of Montezuma
Street.
TASK 2: TOPOGRAPHIC SURVEYING AND MAPPING - KWE will collect field topographic data of
the proposed storm drain alignment route, including mapping the existing land contours at 1-foot
interval, locating existing improvements; i.e., trees, service alignment, paving, and found aboveground utilities that exist at the time of survey. KWE will utilize the city’s vertical datum system.
The topographic limits will include the area of the proposed storm drain improvements.
TASK 3: CONSTRUCTION PLANS AND SPECIFICATIONS – KWE will prepare construction documents
for the new roof drain connections. The construction plans will include necessary call-outs for
hardscape repair and removals as necessary. The construction plans for the new storm roof drain

will include: 1) existing [per owner records] and proposed size of pipe; 2) construction key
description for design of the new building roof drain service with appropriate standard detail
callouts; and, 3) standard details and notes for construction. KWE will coordinate with the
architect to establish the building roof service size, location and pipe material. The location and
size will be based on the architect’s (or plumbing subconsultant’s) recommendation.
TASK 4: DESIGN REPORT – KWE will prepare a brief design report to support the design size of
storm drain pipe lateral. The private storm drain pipe will be maintained by Yavapai County.
TASK 5: CONSTRUCTION STAKING – Construction staking to include the following:
survey
calculations, clearing and match lines, and layout of the new storm drain pipe with offset and cut stakes
for the design invert.
TASK 6: CONSTRUCTION INSPECTIONS – KWE will assist the design team with contractors’ RFI’s,
COR’s and related matters to our work scope. During construction we will provide part-time
construction observation services and as-built trench alignment survey and subsequent as-built
plans. The final as-built plans will be furnished electronically to the architect for review and
submission to the Owner.
Project Schedule: KWE will coordinate this work with your project schedule. We can proceed
after our receipt of this signed contract, notice to proceed, and the client-furnished information
referenced herein.
