Item 2.02.A.6 notes the jack nut housings shall be provided with a system of guide rollers to guide the load carrying lifting beam along the support column. The requirement of this item favors one drop table manufacturer s typical design. In order to allow for a competitive bidding process, we ask this item be revised to indicate a bidding manufacturer s proven standard design and manufacture is acceptable as meeting the requirements of this item. 20A. The specified features are not exclusive to other manufacturers and do not favor any manufacturer. 21. Item 2.02.B.12 notes the requirement for the supply of galvanized steel curb angles around all edges of the surrounding concrete track pit floor that will be installed by the Contractor. This is not typically part of a drop table manufacturer s scope of supply. We ask the responsibility for the design, supply and installation of all steel curb angles around the equipment pit be made part of the Contractor s supply. This material is to be installed as part of the floor that is part of the building and is separate from the design and supply of a drop table system. The responsibility of the material supply should reside with the Contractor performing the floor design and installation work. 21A. See response to Question # Item 2.02.C.1 notes that the movement of the release top shall result from the engagement of lugs attached to spacer posts contacting and engaging with a contact pad or roller on each of four jack nut housings. This requirement favors the design of one particular drop table manufacturer. In order to allow for a competitive bidding process, we ask this item be revised to allow for the use of a bidding manufacturers proven design as meeting the requirements of this item. 22A. This request is an exception to the specification and is subject to the review and approval by SEPTA. 23. Item 2.02.C.10 notes the requirement to furnish galvanized steel curb angles around all edges of the surrounding concrete shop floor that will be installed by the Contractor. We ask the responsibility for the design and supply of all steel curb angles around the equipment pit be made part of the Contractor s supply.

8 Page 7 of The equipment items in Division 14 (e.g., Drop Table, Fall Protection System, Shim Carriage Equipment and Overhead Cranes) are specialty items and we only anticipate quotes on these items from the entities specified by SEPTA in the Specifications, and at least some of those entities are expected to quote both the furnish and installation of these items. Thus, there is virtually no feasible way to obtain DBE participation for these items; accordingly, we request that SEPTA consider excluding the value of each bidder s Division 14 price from the total bid price solely for purposes of determining whether a bidder has satisfied the 16% General Contractor s DBE goal for this project. 43A. The DBE Goal remains 16%.
