Lane Width Requirements
Enquiry
Section 2.4.1.5 Staging / Detours of the RFP states “The minimum lane width on Highway 401 shall be 3.66 m for all stages of construction.” Section 2.2.1 Design Work states that “The existing 3.66m lanes widths on Highway 401 mainline are not required to be upgraded to 3.75 as the Highway 401 mainline work is localized at the bridge sites”. Section 2.4.5.2 Traffic Management Requirements (part c) of the RFP states that the minimum lane width shall be 3.66m. The requirements noted above conflict the following: Section 2.4.8.2 Bridge Design and Construction of the RFP states the “Cross section for each structure to accommodate the Highway 401 cross section and traffic management requirements during construction..” includes a requirement for 3.75m lanes on each structure. Section 2.4.1.5 Staging / Detours states that “the Design-Builder shall be responsible for determining staging / detour requirements in accordance with the requirements set out in the RFP and the 2014 Preliminary Design Report”. The PDR staging drawings (Table C-2, Document # 26) have lane widths of 3.75m. The PDR General Arrangement Drawings (Table C-1, Documents 7 & 9) show lane widths of 3.75m. Please clarify the following: 1) During detour staging are the lane widths required to be 3.66m or 3.75m. Please clarify for both on the structures and off. 2) After bridge construction are the lane widths required to be 3.66m or 3.75m. Please clarify for both on the structures and off.
