- **Buyer and project team**
  - Buyer: Board of Regents of the University of Minnesota; project at University of Minnesota–Morris, EcoCenter.
  - Engan Associates PA is the Architect/Engineer of Record.
- **Shelter and trellis products — OEMs highlighted**
  - **Scenic Shelters, LLC** approved equal: one 30-by-25-foot steel open-gable shelter, model **SOG3025-CUS**, and two 12-by-55-foot custom curved steel pergolas, model **SPE1255-CUS**. These are material-only products; unloading and installation are by others.
  - Basis of design: **Poligon (PorterCorp)** Kokomo Amphitheater shelter and Poligon Concord Trellis. The shelter includes a standing-seam steel roof over prefinished tongue-and-groove Hem Fir decking. Drawings also specify ALMA-style columns.
- **Construction scope and other specified products**
  - Base work includes site work, shelter and trellis construction, concrete foundations and slab, and conduit for future electrical. Concrete specifications include reinforcing steel, cast-in-place concrete, masonry units, architectural cast stone, and aluminum railings.
  - Additional specified products include **VPR RET-4** under-slab vapor retarder; low-gloss and high-gloss curing/sealing compounds (CONC SLR-1 and CONC SLR-2); and **Greenstreak Hydrotite CJ-0725-3D** cold-joint waterstop, or approved equal.

  - Construction budget is **$360,000**. Quantities for specification-section materials beyond the shelter and pergolas are not stated.
- **Notable project requirements**
  - Prevailing wages applicable to Otter Tail County apply. The contractor must provide temporary power by generator or batteries because owner power is unavailable.
  - The general contractor must obtain the building permit, and excavation requires a separate excavation permit. Shelter structural-frame and factory-finish warranties are each 10 years.
  - The project is tax-exempt for charges to the University, but the exemption is not transferable; the contractor remains responsible for taxes on third-party purchases.
