|Prior Reference #22016234 Change Order T-035 Deck Slab Repairs: The contractor has requested an additional deck slab repair line item for deck slab repair locations where the existing concrete overlay was not removed according to the Concrete Bridge Deck Scarification line item. At the time of bid the unit price for partial depth deck slab repairs was based on a maximum depth of 3.75”, which is half the thickness of the plan’s typical 7.5” deck. With only one applicable pay item the contractor would have anticipated that all partial depth deck slab repairs would be treated in the same manner. However, through RFI No. 2 and subsequent Proliance correspondence, it was determined that the project would consist of the following two distinct types of Partial depth deck slab repairs:|
1. On deck areas to be scarified and overlaid with latex concrete, the partial depth deck slab repairs would require an unfinished surface and have a depth up to 3.75”, which is half the thickness of the plan’s typical 7.5” deck.
2. On deck areas with existing overlays that are not to be scarified and overlaid, the partial depth deck slab repairs would require a finished surface and have a depth of up to 4.75”, which is half of the total 9.5” deck thickness (7.5” original deck + 2” existing overlay).
