This type of failure could lead to catastrophic damages to the house, exponentially increasing the cost of remediation. These types of damages are typically not covered under many homeowners' insurance policies.    Structural Solution Shored up house and removed the existing foundation one section at a time. Once each section was shored and the section of foundation was removed, a new foundation footing was poured and a new steel reinforced foundation was installed complete with waterproofing.   Foundation Replacement Bowed foundation wall Bowed foundation wall Bowed foundation wall Removed bowed wall and shored section of house Preparing new foundation footing Laying CMU block to replace foundation Horizontally and vertically set rebar Steel reinforcement of CMU block Filled block with concrete and steel Masonry near completion Finished view Finished view   Wood Beams and Columns Replaced with Steel Customer Post Oak Property Management   Location Racine Ave, Chicago   Symptom Deflecting/bowing beams and deteriorated wooden columns.    Problem The deflecting wooden beams and deteriorated wooden columns created an unsafe condition and sagging and sloping floors in the 3 units above the basement.   Structural Solution Replaced failing beams, columns and footings in the basement of a 3-unit apartment building. Temporary shoring and jacking equipment was installed to support the structure while the old structural members were being replaced. The jacking equipment was used to incrementally jack up the floor joists at the beam location to a level position. Once the level position was achieved, new steel beams and columns were installed with the columns set in steel reinforced concrete footings. Any electrical, HVAC and gas lines attached to the existing structural members being replaced were removed and reinstalled once the new columns and beams were permanently installed.   Beam and Column Replacement   Beam, Column and Footing Replacement Customer Residential Customer   Location Mt. Prospect, IL.   Symptom Sagging Floors and Cracking Walls   Problem The existing structural members consisted of a combination of deteriorated 4” X 6” wood beams and columns and temporary shoring devices (non-conforming to building code) all of which were deemed to have footings that had insufficient load bearing capacities. These findings were found to be factors leading to unsafe conditions, sagging floors and cracking walls.   Structural Solution Replaced the inadequate beams, columns and footings. The installation procedure involved removing the wood beams and columns and replacing them with double Laminated Veneer Lumber (LVL) beams and steel columns that were set in steel reinforced concrete footings. Temporary shoring was installed to support the structure while the old structural members were being replaced. The shoring was also used to incrementally jack up the floor joists, at the beam location, to a level position. Once the level position was achieved, the new beams and columns were set in place as illustrated in the following photos. Any electrical, HVAC and gas lines attached to the existing structural members being replaced were removed and reinstalled once the new columns and beams were permanently set in place.   Prior to installation Shore and replace existing beams and columns Assemble steel reinforcing for footing Concrete poor for footing New beam, column and footing Completed beam line   Beam, Column and Footing Installation in Crawl Space Customer Residential Homeowner   Location Deerfield, IL   Symptom Sagging floors in living area over crawl space.    Problem Insufficient footings and wood beams and posts deteriorated over time from exposure to moisture.   Structural Solution Replaced failing wood beam, posts and footings in crawl space. Temporary shoring and jacking equipment was installed to support the structure while the old structural members were being replaced. The jacking equipment was used to incrementally jack up the floor joists at the beam location to a level position. Once the level position was achieved, a new steel beam and a steel reinforced concrete footing was installed. Installed Steel Beam in Crawl Installed concrete footing     Basement Digout to Increase Floor to Ceiling Height Customer Residential Customer   Location   Evanston, IL.   Alteration   Lower basement floor slab by 18”   Solution   Provide shoring (bracing to support house) to allow for the removal of the existing shorter columns to be replaced with longer steel columns as well as the installation of deeper foundation walls. Shoring used to Support the House While Replacing the Existing Beams & Columns Cribbing to Support the Shoring New Concrete Foundation Installed Under Exisitng Brick Foundation Walls Welder Welding the New Steel Columns   Basement Digout with Installation of Radiant Heat Customer Residential Customer   Location   Oak Park, IL.   Alteration   Shored entire beam line in basement, removed existing timber beams and columns and replaced with steel beams with longer columns and deeper footings to accomodate deeper basement floor, removed existing slab and dug basement deeper, installed vapor barrier and drainage system, tuckpointed stone foundation, and ran tubing for radiant heat in new slab.   Straightened and Reinforced Sagging Roof Rafters Customer Residential Homeowner   Location Winnetka, IL   Symptom Sagging roof line from ridge to eaves.   Problem Home was original built with undersized rafters and rafters were pulling away from walls.   Structural Solution Jacked up existing rafters to a level slope and sistered properly sized rafters along the full-length of existing rafters.  Installed collar ties at the upper end of rafters. Custom fabricated adjustable steel tie rods and fastened rods to bottom portion of rafters, running rods from one end of the width of the roof to the other to inhibit the bottoms of the rafters from pulling away from the walls of the house.   Jacked Up and Reinforced Rafters Rafter Retaining Bracket with Tie Rod Ran Steel Rods from Rafter to Rafter Coupled Rods at Center of Attic with Turnbuckels
