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.
Quantities of each material purchased annually will vary depending on individual project scopes for scheduled projects and unscheduled repairs and maintenance activities.
DISCUSSION: Bid information was sent to five (5) vendors and Bid 1516-11 was opened on September 10, 2015, with three (3) vendors bids received for Portland Cement Concrete. The price of concrete materials has lowered an average of 19.35% over the 2015 bid price reportedly because of decreased manufacturing and delivery costs. If approved, the purchase contract for the materials will be effective through October 31, 2016.
