Title
CONSIDERATION AND AWARDING OF BID 2021-32 FOR THE PURCHASE OF PORTLAND CEMENT CONCRETE FOR USE BY THE STREET AND STORMWATER DIVISIONS.
Body
BACKGROUND: The City of Norman Street and Storm Water Maintenance Programs utilize on a frequent basis the following types of Portland Cement Concrete:
• Class A Concrete is used in pavement slabs, sidewalks, retaining walls, culverts, and all areas where reinforced concrete is needed. Calcium is used as an accelerating admixture to increase the strength of the concrete more quickly during curing. It is used in cold weather application; however, it is not an anti-freezing agent.
• High Early Strength (H.E.S.) Concrete is used for driveway and pavement replacement.
• Fast Track Concrete is used for emergency panel replacement in high traffic areas the PSI is 3000 on 8-hour strength test.
• Grout Mix is used with riprap, for bedding drainage pipe, and stabilizing plastic Subgrade.
• Flowable Fill is used as a liquid concrete mix in bedding and backfilling culvert pipe and storm sewers where 100% compaction is required.
• Additives/Accelerators is used to speed the setting time and when cure time starts earlier. This allows concrete to be placed in winter with reduced risk of frost damage.
Quantities of each material purchased annually will vary depending on individual project scopes for scheduled projects and unscheduled repairs and maintenance activities. A total of 1174 cubic yards of Portland Cement Concrete were purchased in FYE 2020 at a cost of $145,964.50.
