CSI DISCUSSIONS OF THE WEEK
CONTRACTOR SELECTION ON GOVERNMENT-FUNDED PROJECTS
My client is about to advertise for bids on a building project, which in addition to meeting state purchasing requirements is partially funded with federal relief money. There is consideration for requesting competitive sealed proposals (best value) due to current challenges in the supply chain. Obviously, awarding this type of contract takes more time than a private owner would, which increases price risk. I’m interested in any common-sense solutions which satisfy the purchasing requirement without overburdening the budget or later being unprepared for dealing with a request for increases which could not be anticipated.

PRESERVING HISTORIC CONCRETE BALUSTRADE RAILS
I’m working on a unique project in which 100-year-old historic concrete balustrade rails are in need of repairs and refurbishment. Their surfaces are showing signs of wear and weathering, and I would like to clean the components, make repairs as necessary, and help protect them with some type of permeable coating. A petrographic evaluation has found the majority of the balusters and rails contain no course aggregate, and the binder is straight cement. There is a good amount of carbonation. The baluster grout had a relatively high water to cement (w/c) ration when cast, but 100 years of curing has resulted in a moderate hard paste. The sand has a slightly courser gradation than normally expected and consists almost entirely of quartz, with lesser amounts of quartzite, feldspars, and hematite/goethite. Any thoughts on what type of product(s) to use would be greatly appreciated.
