INTER -OFFICE MEMORANDUM DEPARTMENT OF PUBLIC WORKS DIVISION OF ENGINEERING TO: Linda M. Martin, Clerk Board of Public Works FROM: Zach Hurst, Project Engineer SUBJECT: Change Order No. 1 - Project No. 119-064, Division B 315/319 W. Jefferson Exterior Renovations — Masonry Repair DATE: December 3, 2019 oiiwuwu.�urvrvwwwwwwmmmaw mumowm�uuwuw.wwwwuiwmwmwiwworvwwwrvuwniwwwwuwwwwwvew nn�rowooronrrworarr.mmomiamua On October 11, 2019, Ziolkowski Construction advised Cressy Commercial Real Estate and the City that upon power -washing the exterior brick at the subject property, it became apparent that grinding and tuck -pointing of the brick walls was required to ensure proper rehabilitation and sealing of the masonry and ensure adherence to the project specifications and anticipated service life of the repairs being funded by taxpayer dollars. The dollar amount of the added tuckpointing and grinding ($24,798) is 62.66% greater than the original contract value ($39,574). The extent of deterioration was not noticeable during project design, and was uncovered during construction, resulting in unforeseen conditions. As the conditions were unforeseen, and could not have been discovered before the power -washing of the brick, I am recommending approval of this change order. Please call with your questions (3057).
