Integrating Ca4prs V.3 Road Widening Schedule Module Into Us Highway Early Constructability Process: California Sr-91 Corridor Improvement Program Case Study

“…CRP have been found to increase the efficiencies of agency procurement and staffing, the quality of design, the efficacy of construction methods, and overall team integration and project performance equating to project cost/benefit ratio of 1:2 (Gambatese et al 2017). While a majority of agencies have CRP manuals, which promote NCHRP and FHWA identified best practices (Anderson, Fisher 1997;Stewart et al 2017;FHWA 2019), they have been found to require significant agency resources (Dunston et al 2005), lack RUC and schedule considerations (Anderson, Fisher 1997;Saghatforoush et al 2011), and fail to provide managers with visualizations of alternatives (Kifokeris, Xenidis 2017). This publication proposes the CA4PRS v.3 software, road widening schedule module, to mitigate these identified CRP issues.…”

“…This discussion began with a NCHRP publication, which provided agencies with an overview of the suggested tools, processes, and best practices to be used in CRP (Anderson, Fisher 1997). A majority of agencies have disseminated findings from this publication in their own CRP manuals (Stewart et al 2017). Furthermore, successful CRP modifications are catalogued by the FHWA Work Zone Management Program on their CRP Best Practices website (FHWA 2019).…”

“…Furthermore, successful CRP modifications are catalogued by the FHWA Work Zone Management Program on their CRP Best Practices website (FHWA 2019). Twenty years after their first investigation, the NCHRP performed a follow-up assessment of the efficacy of agen-cy CRP tools, processes, and best practices (Stewart et al 2017). They found the CRPs often rudimentary, with agencies lacking confidence to calculate a measurable payback for chosen alternatives (Stewart et al 2017).…”

They found the CRPs often rudimentary, with agencies lacking confidence to calculate a measurable payback for chosen alternatives (Stewart et al 2017). Agencies lack the resources, expertise, or the time to dedicate to holistic CRPs (Dunston et al 2005;Stamatiadis et al 2013) and bringing in external construction personnel often created conflict of interests (Stewart et al 2017).…”

Existing CPR practices succeed in evaluating the implementation challenges of the contractor but often lack in incorporating life-cycle maintenance (Saghatforoush et al 2011) and/or RUC impacts in their assessments (Anderson, Fisher 1997).…”
