1 August 9, 2016 Ms. Jennifer Spencer, AIA, NCARB Gary W. Anderson Architects 200 Prairie Street, Suite 201 Rockford, IL Subject: Structural Observations 227 North Wyman Street Rockford, IL Dear Ms. Spencer: Fehr Graham was requested to provide structural observations of the building at 227 North Wyman Street in Rockford, Illinois. We visited the site on July 27, 2016, and made the following observations. OBSERVATIONS General Observations The building is a two story masonry structure with a full basement. The exact age of the building is unknown, and it appears that the structure has had two additions, also at dates unknown. The structure is at the southeast corner of the intersection of Wyman Street and Jefferson Street, with the front of the building facing northwest onto Wyman Street. For the purposes of this report, the front of the building will be assumed to face west. The entire structure is approximately 145 feet along Jefferson Street and 50 feet along Wyman Street. Exterior Observations The east addition, approximately 32 feet long, provides a carport, and in addition, a staircase that was added, which wraps around the adjacent addition along the south elevation. No structural deficiencies were observed to the east exterior elevation. Along the north elevation, a narrow vertical crack was observed at the far east end in the masonry and into the concrete column at the end of the carport (see Photograph No. 1). Further west along the building an abandoned access structure from the building onto Jefferson Street was observed to be corroded, with holes through the members and floor (see Photograph No. 2). Under the walkway, there is a small area of missing brick and mortar (Photograph No. 3). Near the west end of the north elevation some minor efflorescence was observed near the roof elevation (Photograph No. 4). No structural deficiencies were observed to the west exterior elevation. The south exterior elevation could not be completely observed. Approximately the middle third of the elevation is covered in vegetation (see Photograph No. 5). For the areas which could be seen, no structural deficiencies were observed. 200 Prairie Street I Suite 208 I Rockford, IL I p: I f: I Insight. Experience. Results.

2 August 24, 2016 Ms. Jennifer Spencer/Gary W. Anderson Architects Structural Observations Report Page 2 Access to the roof is provided by a hatch along the north elevation in the center portion of the building. The roofing consists of a rubber membrane, and approximately 1 of rock ballast. The membrane is in good condition, with no tears or holes observed. At the southeast corner of the building the compression bar holding the roofing to the parapet was noted to be bent and disconnected for a short distance (see Photograph No. 6). There are HVAC units on the roof, and no roofing deficiencies were observed at these locations (Photographs No. 7 and No. 8). Interior Observations The roof framing is completely exposed and was observed from the second floor. The east portion of the building roof consists of steel bar joists and steel beams supporting a corrugated metal decking (see Photograph No. 9). The center portion of the building roof consists of steel beams and girders, encased in concrete, supporting a cast in place concrete deck (Photograph No. 10). The west portion of the building roof consists of steel trusses, at spaces varying between approximately 13 to 17, supporting concrete beams at the panel points, which support a cast in place concrete slab (Photograph No. 11). No structural deficiencies were observed to the roof framing. The stairway wall at the second floor exhibits some narrow stair step and vertical cracking emanating from the top of the west end of the door frame (see Photograph No. 12). The second floor framing is exposed and was observed from the first floor. The east portion of the second floor framing consists of steel girders and beams supporting a corrugated metal deck. The steel framing has had fireproofing applied (see Photograph No. 13). The east-center portion of the building consists of concrete girders and beams with a cast in place concrete deck, all of which has had plaster applied to the surface (Photograph No. 14). The west-center portion of the building consists of steel beams and corrugated metal deck, and appears to have been added as an infill (Photograph No. 15). The west portion of the second floor appears to be cast in place concrete beams and slab (Photograph No. 16). The openings between the center portion and the east portion are exposed and the lintels and brick are exposed (Photograph No. 17). No structural deficiencies were observed. The first floor framing is exposed and was observed from the lowest level. The framing consists of cast in place concrete girders, beams, slabs, and columns. The majority of the framing is in good condition, with the exception of one short beam near the south side of the east end of the center portion. The beam between the wall and the adjacent column exhibits a shear crack through the width of the beam (see Photographs No. 18 and No. 19). CONCLUSIONS AND RECOMMENDATIONS In my professional opinion, the existing building is in generally good structural condition. With the exception of the concrete beam supporting the first floor which exhibits cracking through its width, no items were observed which compromise the original structural capacity.

3 August 24, 2016 Ms. Jennifer Spencer/Gary W. Anderson Architects Structural Observations Report Page 3 In my professional opinion, at the second floor areas where the steel beam sizes and spaces can be determined, the floors in these areas are capable of supporting a Live Load of approximately 50 pounds per square foot, equivalent to the International Building Code requirement for office space. In the areas where the first floor and second floor framing consists of reinforced concrete beams and girders, no selective demolition was performed to determine the reinforcement. In my further professional opinion, for the given beam sizes and spaces and conventional reinforcement, those areas should also be capable of supporting a Live Load of approximately 50 pounds per square foot. In my professional opinion, the roofing is in generally good condition, with no obvious areas of distress. I recommend that the compression bar in the southeast corner be reattached to prevent the membrane from coming loose. I recommend that minor repairs be undertaken to the existing exterior of the building in the near future. Cracks, missing brick, and missing mortar in the exterior brick wythe, are avenues for moisture intrusion which will, in time, create structural deficiencies. Further, I recommend that the vegetation growth on the exterior be removed. The vegetation can weaken the mortar and eventually cause structural damage. I recommend that the walkway between the existing building and Jefferson Street be removed in its entirety and be replaced, if access is desired in the future. If future access is not desired, the walkway should be removed and access denied. In my professional opinion, the load carrying capacity of the short beam exhibiting shear cracking, which is part of the first floor framing, has been compromised. I recommend that shoring beneath the cracked end of the beam be installed and supported on the concrete floor below. Should you have any comments or questions, please do not hesitate to contact us.
