Council authorizes staff to proceed with field directive on Colorado Boulevard sewer upsizing after encountering unexpected culvert

Council authorized staff to issue a field directive on the Colorado Boulevard Sewer Upsize Phase 2 project after staff reported an unexpected field condition in which a reinforced-concrete culvert shown on plans proved to be a larger box culvert in the field.

Adam Jones told the council the contractor must jack-and-bore a steel casing beneath the box culvert to install the upsized sewer and that contractors plan to honor bid pricing for the work. "The estimated dollar amount of this change is in that $125,000 range," Jones said; staff said a final dollar amount and a formal change order will be returned to council for final approval at a future meeting.

Staff noted the project was awarded previously, the base contract includes relevant work items, and that the project is partially funded with grants and an SRF loan requiring state approval of changes where applicable. Council approved authorization to proceed so work would not be delayed.
