INTER -OFFICE MEMORANDUM DEPARTMENT OF PUBLIC WORKS DIVISION OF ENGINEERING TO: Linda M. Martin, Clerk Board of Public Works FROM: Kyle Silveus SUBJECT: Change Order No. 1 — 119-042 Lafayette Building Drain Replacements DATE: August 8, 2019 The Lafayette building is being renovated to protect and secure the exterior of the building. Work on the building includes masonry, skylight, and roof drain repairs interior to the building. This drain replacement project has encountered an unforeseen condition that was not reasonably foreseen during the design phase and is going beyond 20% of the contract value. The sub floor drains were deteriorated to the extent that the top third of the metal pipe was gone,. There was no way to tie in the replaced roof drains interior to the building without having a good piece of pipe to attach to. The concrete floor needed to be cut and removed to chase the existing deteriorated piping to the east end of the building to find a good section of pipe to tie into. The trench was then backfilled with sand. Change order 1 is the last change order for the project and is an increase of $20,745.60, or a 55.88% increase from the original contract value. Please call with your questions,.
