2026 Sanitary Sewer Improvements Project - Sioux Falls, South Dakota

This is a comprehensive set of construction plans prepared by the City of Sioux Falls Public Works Department for sanitary sewer improvements spanning K Avenue, Blackhawk Street, M Avenue, and Cherokee Street. The project encompasses partial street reconstruction, removal of existing sanitary sewer mains, storm sewer improvements, asphalt pavement replacement, curb and gutter repairs, and landscaping. The work involves installation of new sanitary sewer piping ranging from 4 inches to 15 inches in diameter, water main relocation and installation (4 inches to 16 inches), and storm sewer improvements including removal and replacement of reinforced concrete pipe. Over 166 line items are identified, including excavation (2,210 cubic yards), aggregate base course (4,438 tons), asphalt concrete surfacing (1,745 tons), topsoil placement (394 cubic yards), seeding and fertilizing across disturbed areas, and manhole construction. The project is divided into multiple phases with specific completion deadlines: Phase 1 by June 1, 2026; Phase 2A by October 2, 2026; Phase 2B within 15 working days of security fence removal; and Phase 2C within 15 working days and by October 2, 2026. All work must achieve substantial completion by October 2, 2026, with final completion including punch list items by November 13, 2026. The project includes work within the South Dakota Air National Guard Airbase property, requiring background checks and security clearance verification for all personnel.

The estimated project cost is $1,733,672.60, funded through CIP No. 23001. Liquidated damages apply for non-compliance with phase and overall completion dates, ranging from $450 to $650 per working day depending on the phase. The contractor must obtain a South Dakota State Sewer and Water Plumbing Contractor's License prior to commencing work. Contractors are responsible for all utility locating and verification, with the City of Sioux Falls One Call system and private utility companies providing initial locates, though contractors must arrange specialized locates for the Airbase property. The project includes comprehensive erosion control and stormwater pollution prevention requirements, geotextile fabric installation for subgrade stabilization, traffic control management with maintained business access to adjacent commercial properties (Amcor and All American Towing), and temporary sanitary sewer bypass operations. Electronic design files are available upon request with signed disclaimer agreements. The contract terms include standard provisions for weather delays, inspection protocols, acceptance testing, and a 45-day maintenance period for permanent seeding and landscape restoration.
