Alvine Engineering provided engineering consulting services for the exterior restoration of the Oklahoma State Capitol. The project scope consisted of address exterior egress and emergency lighting, storm drainage and sump pumps, and renovating the existing east tunnel.

Most entrances to the Capitol had decorative bronze post-top luminaires original to the 102-year-old building that were in disrepair and, in one case, completely missing. Alvine Engineering collaborated with the project team and brought in a specialty antique lighting restoration company to ensure luminaires were restored to historically-accurate conditions.


  • Designed stormwater management around the exterior of the building, including stormwater collection systems and sump pump discharge assemblies that removed stormwater from basement level light wells to appropriate discharge locations.
  • Investigated water infiltration of the underground pedestrian tunnel and identified remedies with the project team.
  • Designed egress lighting at south portico entry, integrating recessed lights into the original coffered ceiling.
  • Designed egress lighting at stairwell entries on all sides of the Capitol by integrating LED lighting into custom handrails. Alvine worked with the project team and handrail manufacturer to develop mock-ups and shop drawings to confirm installation details for custom decorative illuminated handrails.
  • Facilitated design and construction process to remove surface mounted conduit and restore historic bronze post-top luminaires to original condition with retrofit LED lighting. The restoration process included a site visit to the antique lighting company’s factory to witness the restoration process.
  • Coordinated exterior lighting controls and circuiting with a separate project team for the executing interior renovation of the Oklahoma State Capitol.
