Mortar is the consistency of powder and provides insufficient strength for shoring 2. Masonry was poorly installed and insufficient mortar was used 3. Masonry unit is a paver without core holes - not a brick. Bond between mortar and pavers is weak 4. The building does not have rigid sheathing. The brick is essentially free-standing outside of the structure 1. Mortar is the consistency of powder and provides insufficient strength for shoring The exterior is solid while the interior is a powder consistency. The drill easily penetrates the mortar with little resistance. There is very little material in the head joints. The material from the joint was collected as if fell out during drilling. The largest piece was removed by hand from the interior side of the wall. Most of the chunks are smaller than a nickel. 2. Masonry was poorly installed and insufficient mortar was used The interior side of the wall shows poor installation. The head joints are open, with only a face shell of mortar on the exterior. The bed joints were not completely filled. The mortar droppings can be broken o� by hand. For comparison we drilled holes at Swedish Hill to test the resistance of the mortar. The mortar has more consistency and was installed with better workmanship. This type of mortar is necessary to implement the shoring design we proposed for 1116. 3.

Salvageable materials will be reconstructed in a manner that matches the original façade as closely as possible. Any materials that need to be replaced will be in kind and match the existing material. • Original Brick. Use only original, salvaged bricks to rebuild the front facade. • Ornament, Etc. Salvage and reuse as much as possible the unique ornament, coping stones, canopy metalwork, etc. There are portions of the canopy structure that are either unstable or structurally unsound to be reused • Preservation Architect. Engage a preservation architect to consult on the restoration. 1116 West 6th Street 1. Existing structure 4’ 2.
