Watch out for

Corrosive soil conditions present — corrosion testing results in Exhibit 6-1 & 6-2
Expansive subgrade potential identified (Section 6.1)
Frost damage risk documented (Section 6.2)
Soft subgrade conditions possible (Section 4.2, 7.2.3)
Groundwater present on-site (Section 4.4)

Deep Document Summary

Key Scope Items

Access road reconstruction: single-lane, 0.2 miles long, 18 feet wide, leading from SD Highway 19 to visitor center
Parking lot reconstruction: approximately 7,000 square feet
Both surfaces currently asphalt concrete pavement (ACP) with documented distress (fatigue, block, longitudinal, and transverse cracking)
Pavement design recommendations based on subsurface exploration and lab testing
Site preparation, earthwork, subgrade preparation and compaction
Lime-treated subgrade (LTS) per construction recommendations
Full-depth reclamation (FDR) as an alternative option

Notable Requirements

None specified.

Critical Dates

Subsurface exploration conducted: June 11, 2025
Design report prepared: November 2025
Master Agreement with HDR Engineering dated: May 20, 2025

Red Flags

Corrosive soil identified at site — corrosion testing results documented (Exhibit 6-1); contractor must verify sulfate and water-soluble sulfate exposure ratings before material selection
Expansive subgrade potential and frost damage risk noted in design report — special construction sequencing and material controls may be required
Groundwater present on-site — subsurface variability documented; soft subgrade conditions may require specialized handling (Section 4.2–4.5)
