West Suburban Hospital
Water Infiltration
Oak Park, Illinois

SEE was retained to evaluate and repair water infiltration at the professional building. This office building was built a few years ago and has had water infiltration at every level. SEE initially reviewed a limited number of window shop drawings and architectural drawings to understand the design, installation and anchorage details, and air and water weep system.

SEE performed water testing from swingstage scaffolding to determine approximate locations of water infiltration. A masonry contractor removed masonry at these locations in order to evaluate the hidden condition and detailing. SEE discovered that the flashing details were improper. We prepared a new flashing detail with new flashing material and anchorages. After completion of the repair we performed water tests to verify watertightness. Based upon successful repair SEE recommended allocating funds to repair water infiltration at the remaining areas of the building.

Cerestar USA, Inc.
Condition Assessment of Refinery Buildings
Hammond, Indiana

SEE was commissioned to assess the existing condition of four refinery buildings located within the Cerestar USA facility. The objective of our assessment survey was to identify visible structural and related deficiencies and make recommendations on the overall condition of each building. The buildings were constructed at different times ranging from 1907 to 1962. Based on the operational requirements and the extent of deterioration in each building, SEE concluded that only one building could be repaired cost effectively and it would be most cost effective to demolish and re-construct the other three buildings. Due to the severe deterioration observed, SEE made emergency recommendations that included immediate shoring and implementation of a monitoring program until repairs are made or the buildings are demolished. Our client hired SEE to oversee the installation of the emergency shoring and monitor the buildings until funds become available.

W.M. Construction, LP

Condominium Association
Pool Gutter Renovation and Lining
Chicago, Illinois

The existing steel pool gutter which incorporated an integral deck drain was severely deteriorated. In particular, the separation plate between the two gutter systems was extensively corroded. Hence, gallons of treated pool water was lost every day. Additionally, runoff water entering the deck drain was infiltrating and contaminating the pool water. No construction information was available on this unique 25 year old steel wall and concrete base pool. SEE developed an evaluation program to investigate and rehabilitate the pool. Our solution replaced the old steel gutter with an efficient self skimming stainless steel gutter and included installation of a 60-mil thick reinforced PVC pool liner.

Exterior reinforced concrete walkways provided access to the second floor stores. The walkways were cantilevered from the building and exhibited concrete deterioration. Our client wanted to know if the walkways and stairs could be repaired or need to be replaced. They also wanted to know if the construction work could be performed without closing access to the second floor especially to the restaurants which are open for breakfast, lunch and dinner. After reviewing field conditions and considering ADA requirements, SEE concluded that it was most cost effective to replace the walkways and stairs. Several different options were studied and it was determined that precast concrete walkways serve our client’s needs best and access to the second floor will be maintained at all times during construction.

Royal Glen Condominium Association
Swimming Pool Rehabilitation
Glen Ellyn, Illinois

When the existing pool supply piping was no longer functioning properly, our client retained the services of SEE to design a rehabilitation program to allow use of the pool. The pool supply piping buried under the concrete pool was severely corroded and had to be replaced. To access the deteriorated piping, a trench was cut through the concrete down the center of the entire pool. SEE designed a new PVC buried piping system as well as the necessary reinforcing to structurally tie the pool back together. Other concrete repairs and sealant replacement was specified. The pool was back in operation and functioning properly after rehabilitation.

Existing Condition Assessment
Joliet, Illinois

SEE was retained to assess existing conditions of the floor and precast wall panels at this 480,000 square feet warehouse building. The new warehouse building showed wall panels movement and floor settlement that hindered the forklift traffic. Hence a grouting contractor was retained to mud jack the floor slab. After mud jacking the floor slab exhibited cracking and precast wall panels showed movement. SEE was asked to review existing conditions and make corrective recommendations. After assessing the existing condition and reviewing the designed documents SEE determined that the precast wall panels were not anchored to the foundation properly and mud jacking made the conditions much worst. Many of the precast wall panels were moved out at the bottom by more two inches. We recommended a comprehensive repair program along with cost estimate.
