Subject: Proposal for Professional Engineering Services Relating to the Clara Avenue
Phase 2 Improvement Project
Amendment No. 1 Proposal – Additional Engineering Services
Dear Tim,
We are pleased to provide you with this amendment proposal for the additional
engineering design services for the Clara Ave Phase 2 Project relating to the water main
replacement.
Project Background
During the design process of this project we brought to the City’s attention that there was
a section of 40+ year old 6” ACP water main within the paving reconstruction limits that
they should consider replacing with new PVC pipe. This ACP section of water main is
approximately 690 feet in length (1978 vintage) that goes from 160’ west of the Sidnie
intersection to N. Orchard. All of the other water main within the paving reconstruction
limits was replaced with new 6” PVC pipe in 2010 with phase 1 of the Clara Avenue
improvements. Due to the age of the existing ACP water main and to prevent the need
to do future trenching in the newly placed pavement, the City elected to have this water
main replacement added to the project. As these improvements for the water main were
not part of the original scope of work, we are asking for an amendment to cover the
additional design efforts required to incorporate the water main improvements into the
final bid documents. Additional design efforts include plan and profile plans, construction
notes, research/coordination with City on the waterline background information and
miscellaneous construction details. Other additional efforts include preparation of the
water facility specifications and an engineer’s estimate of construction cost.
Based on the above understanding of the additional required services, we have prepared
the following scope of work and estimated fee for your consideration. For clarity, the tasks
below follow the original scope of work.
"55"$).&/5"
SCOPE OF SERVICES
Task 1 – Meetings with City Staff
No additional work under this task.
Task 2 – Background Information
Coastland will assemble all of the available City information pertaining to the existing
water main including as-built drawings, GIS files and any additional pertinent information.
Task 3 – Topographic Survey
No additional work under this task.
Task 4 – 100% Submittal
Preparation of water main plan and profiles plans, construction notes and miscellaneous
details. Preparation of technical specifications for water main and associated
appurtenances and an engineer’s estimate of construction cost.
Task 5 – Bid Support
No additional work under this task.
ESTIMATED COSTS
Based on our scope of work, we are proposing that the services associated with additional
design efforts be completed for a not-to-exceed amount of $4,615. The amount quoted
is assuming that all of the work for this project will fall under the scope of work as
previously described. If additional work is necessary that falls outside of this scope of
work, we can either re-negotiate a new scope of work or provide these services on a time
and materials basis per our adopted schedule of hourly rates.
Please let me know if you have any questions.
Sincerely,
COASTLAND
