Greiner provided pre-construction and construction services for renovations to the historic Guardian Building in Lowertown St. Paul.

The scope of work included:

  • Modifications throughout the building, per LEED design standards
  • Complete renovation of the 3rd and 4th floors to accommodate a new tenant
  • Construction of a staircase and skylight
  • Installation of a bio solar rooftop

Office amenities include:

  • Enclosed offices
  • Conference rooms
  • An open meeting space
  • Restrooms
  • A kitchen area

Greiner constructed a staircase connecting the 3rd and 4th floors with the installation of a skylight. The staircase installation involved the removal of slab on steel decking which required modification of the building structure to support the building’s structural integrity.

In addition to the tenant space, Greiner led the installation of a bio solar rooftop. As the first installation of a true bio solar roof in Minnesota, this included a green roof consisting of plants to reduce roof temperatures, manage stormwater, and produce pollinators, along with the integration of solar panels to generate electricity for the building.

Greiner’s work to increase the building efficiencies of the Guardian has started the progress of the building’s LEED Gold certification status.

This project was delivered by the successful partnership of Terry Leonard and Jim DeRocher.
