Project: Building Envelope Evaluation & Wall Analysis - Energy Substation Facility
Location: Detroit, Michigan
Services: Building Evaluation, Roof Evaluation, In-Depth Exploratory Analysis, Recommendations
Summary: Detroit Edison, a part of DTE Energy, had been experiencing significant signs of problems at their Chandler Substation for many years. Because the problems had been evident for many years, DTE had become concerned about the structural integrity of the building. StructureTec performed a preliminary visual survey and determined that an exploratory analysis with wall openings was necessary to accurately determine the extent of the problem and develop recommendations for remediation. StructureTec was able to determine that the building was still structurally sound but unless the problems were addressed within the next few years, the building structure would be jeopardized. The problems included corroded, embedded steel, damaged masonry, degraded joints, staining, cracks in the concrete, etc. StructureTec developed recommendations and the affiliated budgets for addressing these multiple problems.

Project: Exterior Masonry and Below-Grade Restoration - Multistory Corrections Facility
Location: Toledo, Ohio
Services: Evaluation, Design Development, Guide Specifications
Summary: Lucas County was experiencing significant distress and leakage in the new corrections center. The leakage was occurring primarily below grade, particularly at the stairwells. Above grade, the walls were displaying masonry staining and efflorescence with minor stair-step cracking. StructureTec conducted a visual inspection and flood testing to determine the areas of water ingress and the path of water migration. Rilem tube testing, destructive testing, and boroscope analysis were also used to determine the porosity of the masonry and the existence and condition of through-wall counterflashing systems. StructureTec designed new flashings and terminations at the base of the walls. Removal and replacement of damaged masonry units, tuckpointing of deficient mortar joints, and application of a clear repellant sealer were also included in the restoration project. The original contractor was then contracted to correct all of these deficiencies.
