Body
SUMMARY/KEY POINTS
• The Erie Lake Dam Seepage Rehabilitation Project is currently under construction.
• During construction it was discovered that the Lake’s outlet works needed to be repaired and renovated.
• HDR requires an amendment to their Professional Services Agreement in order to complete this additional design work.
BACKGROUND OF SUBJECT MATTER:
The Colorado Dam Safety Office of the State Engineer (SEO) performed the annual inspection for Erie Lake Dam on Sept. 26, 2022 and observed pooling water at the downstream toe of the dam, located along the southwest portion of the embankment. SEO instructed Town staff to institute a daily monitoring plan and to update data on a shared file with photographs and measurements. On Sept 27, 2022, the Utilities staff cleared vegetation from the wet area and identified the active source of seepage. The Town’s Utilities department contacted HDR for support on evaluating the seepage issue. HDR was to perform a data/records review of pertinent available documentation, perform an onsite dam examination, and deliver a technical memo of findings and recommendations. Subsequently HDR was engaged to perform design of the selected remedy, that work has been concluded and the project is under construction.
During construction it was discovered that the lake’s outlet works needed to be repaired and renovated. This amendment to HDR’s contract will allow them to complete the required work.
