Poor Performing Areas
Enquiry
Page 77 of the RFP indicates that the design-builder is responsible for developing and implementing repair methodology for the poor performing areas indicated. A review of the geotechnical investigation provided with the RFP indicates that many of these poor performing areas are resulting from trapped water due to the elevation of the subgrade at the shoulder being higher than the subgrade of the highway – creating a “bath-tubbing effect”. To achieve positive drainage and eliminate the root cause of the poor performance, substantial removal of the existing shoulders to lower the subgrade to match the highway subgrade elevation is required. Furthermore, the lowering of the subgrade through the shoulder will necessitate the lowering of the ditch inverts to match. The geotechnical information provided indicates the presence of rock in some of these areas, which will require extensive rock blasting and excavation. Can the Ministry please clarify if the intended scope of work includes blasting and rock removals to address the poorly performing areas and if this scope has been included in the workload rating?
