Project : 2335 N. Commonwealth St, Chicago, IL

Next Gen Services, Inc. was asked by the A/E to provide masonry contracting services to facilitate his investigation of a damaged window lintel at a 1920s vintage brick and limestone courtyard building in Lincoln Park. The stone needed repair because it had fractured in response to corrosion build up on the steel shelf angle located directly above it. The large limestone lintel, measuring 9-1/2” x 12” x 9’-6” posed difficulties due to its sheer size and weight. NGS removed adjacent masonry, affording the A/E a clear view of the subsurface conditions that caused the cracking.

NGS repaired the lintel at the request of the condominium association, using a motorized chain fall hoist mechanism to remove it from the wall. Repairs included steel staples and epoxy adhesive and the stone was replaced after a new section of steel shelf angle was installed including a full flashing to prevent future corrosion and resulting damage.

NGS’ expertise with vintage and historical masonry buildings assisted the A/E in designing a permanent repair that will be the model for lintel repair in the association’ s upcoming, multi-phased facafe maintenance plan.
