Capabilities · Masonry & building envelope
Masonry and building envelope work on occupied federal buildings.
Brick façades, steel lintels, glazed block and structural masonry, matched to historic requirements and built around building occupants.
What we do
For USDA in Peoria, SIS replaced three stories of radius-corner brick façade, glazed block and steel lintels on an occupied research building in a historic district, keeping the main entrance open the entire time.
We have also repaired structural masonry for the Missouri Air National Guard at Jefferson Barracks and column structure for the Illinois Air National Guard's 183rd Wing.

Masonry on occupied and historic federal buildings
Many federal buildings in the Midwest are masonry structures from the early and mid-20th century. Their façades, parapets and lintels eventually need repair or replacement, and the work happens with the building in use, the public walking past and, often, historic requirements on how the result must look.
SIS's USDA façade project in Peoria brought all three together: three stories of radius-corner brick on an occupied research building in a historic district, with the main entrance open every day and new brick matched to meet Peoria Historical Society requirements.

How we deliver it
How we protect the public and the building
- Step 1
Controlled access zone
A safety plan defines a controlled access zone that keeps the public clear while sidewalks and entrances stay usable.
- Step 2
Match the original
Brick, mortar color and joint profile are sampled and approved before work starts, especially in historic districts.
- Step 3
Work in sections
Façades are completed one elevation or corner at a time, replacing lintels and block as work progresses.
- Step 4
Lift and access
Tower lifts and radius platforms put crews safely at the work face on curved and tall walls.

Frequently asked questions
Can SIS match historic brick on a federal building?
Yes. On USDA's Peoria façade, new brick was selected to match the existing building and meet Peoria Historical Society requirements.
Can masonry work proceed while a building stays open?
Yes. SIS uses controlled access zones and phased work so entrances and sidewalks remain usable, as on the USDA project, where the main entrance stayed open throughout.
