HomeMy WebLinkAboutauthorization of early workMorning Will,
Thank you for sending this.
The plan is acceptable from the perspective of physical improvements (cut/cap, demo, new main) to the water main, however, the plan does not appear to specify settlement monitoring.
Please update the plan to provide settlement monitoring, if acceptable I’ll stamp the plans for final approval.
Please note that since we are ok with the cut/cap, demo locations as depicted, Tom has coordinated with our shops for scheduling of the work later this week. He will be in contact with
the field crews regarding this and the associated needs.
Additionally, until the plans depict settlement monitoring and are signed by city staff, pile driving will not be allowed.
Thanks,

Subject: C22005747 - water main adjacent to viewing deck platform
Will,
As discussed, following a site visit today to discuss water main cut/caps/valve-cut-in’s/etc. with the City inspector, maintenance crews and contractor, installation of the viewing deck
platform was discussed. Given the method of construction is pile driving, along with other requirements indicated, the City is not comfortable with retaining the 12” water main immediately
adjacent to the deck. As such we’re requesting that the water main be cut/capped immediately to the south of the existing hydrant (see screen shot of C1.02 with location shown in blue)
in lieu of the current proposed location as shown on sheet C1.05 (screen shot with comment in blue for reference). That portion of the water main south of the hydrant would need to
be replaced in kind (see screen shot of C4.02 and C4.05 with comment in blue for reference) and the water main to remain shall be monitored for settlement (attached is a spec from a
recent capital project defining monitoring for reference). Can you please revise sheets C1.02, C1.05, C4.02 and C4.05 and send to me for review/approval?
From C1.02:
From C1.05:
C4.02
C4.05
Let me know if you have any questions,
Thank you,
