Caltrans Acknowledges Best Partnered Projects
Three world class heavy/highway project teams facilitated by Ventura Consulting Group were honored at the 2018 Caltrans (California Department of Transportation) Excellence in Partnering Awards ceremony in June. In its 18th year, the Caltrans Partnering Awards recognize Caltrans project teams for utilizing Partnering and its best practices to facilitate successful project implementation.
Read on to learn why the following VCG-facilitated projects were among those honored.
Highway 101/Petaluma River Bridge
Best in Class Award for Projects Greater than $50M
“The ability to quickly and smoothly resolve challenges, while finding ways to reduce costs without sacrificing quality, is a sign of a great partnership.” This is what Caltrans representatives had to say about the Highway 101/Petaluma Bridge project, which recieved the highest Partnering award given by Caltrans during this year’s Excellence in Partnering Awards ceremony.
Touted as one of the longest precast, post-tension splice concrete girder bridges in the U.S, the new bridge is located on Highway 101 where it crosses over the Petaluma River in Sonoma County, California.
Aiming to lessen traffic congestion north of San Francisco, the $78.6 million project included construction of a new 907-foot-long, six-lane bridge, which replaces a four-lane bridge built in 1955. In addition to the bridge replacement, this project involved construction of the Kastania Road Overcrossing, four new ramps, two frontage roads, seven retaining walls, and the overall raising of the highway for site-distance improvements.
A major challenge faced by the project team, was conforming and restaging this contract with an adjacent project that was designed independently of the Petaluma Bridge project. Working in close partnership with one another, the two teams devised creative engineering and scheduling solutions that allowed the two projects to proceed logically and eliminated the need for certain temporary facilities.
Further challenges requiring strong collaboration between Caltrans and the JV team emerged upon start of the project’s second retaining wall. Issues ranged from unsuitable soil to conflicts with third party utilities. To mitigate potential delays, the team developed a clever detour, which removed the wall from the critical path and allowed for a major embankment operation to proceed in the new median. The implementation of a Dispute Resolution Ladder enabled the project to proceed on normal terms without any distractions from the potential claim.
A notable success story on this project included an extensive public outreach effort by Caltrans, Sonoma County Transportation Authority, and the JV, as well as coordination with local authorities for detours related to complicated freeway closures. Caltrans’ IPO and SCTA’s project manager went well beyond what could be expected in terms of outreach. The net result was a well-informed public with very few project-complaints.
State Route 58 (SR-58) Hinkley Expressway Project,
Gold Award for Projects Greater than $50 million
State Route 58 is a major connector from Bakersfield to eastern California desert locations. However, the expressway was reduced to two lanes in the city of Hinkley, near Barstow. This project provided a solution to the traffic bottleneck in this area by realigning and widening the expressway to four lanes. Accessible from two bridges, this expanded roadway provides safe access and facilitates mobility for all motorists, particularly Hinkley area residents.
Completed approximately $7.4 million under budget, on schedule and with no safety incidents, best Partnering practices included: the development of a formal Partnering Charter, Evaluation Surveys and Dispute Resolution Ladder, as well as weekly team meetings and regular barbecue events.
During the first Partnering Session, the team established a Dispute Resolution Ladder to address state-mandated water usage requiring construction of the project’s 90% compacted fill zone without water—an impossible task given the dry soils in the high desert. The team cooperated to create a dry compaction test program proving compaction without water was indeed impossible. Consequently, the specification was changed to allow water use without significantly impacting the schedule.
Among other challenges, effective logistic planning was required to safely import 2.6 million cubic yards of fill through an archaeologically and biologically sensitive area with limited access points. Caltrans Environmental, Traffic Design, Traffic Operations, and Construction, as well as Skanska-Teichert JV, San Bernardino County, and CHP, collaborated to establish two separate haul routes. Despite numerous constraints, the plan allowed the project to remain on schedule without greatly affecting the public.
Managed with a “project-first” focus, the project team at Caltrans and the Skanska-Teichert JV always met face to face to discuss solutions before any correspondence was sent. This and other partnering practices built significant trust and allowed the team to find solutions that best benefited the project, instead of positioning for claims in the future.
I-210 Pavement and Median Barrier Replacement
Silver Award for Projects Between $10 and $50 million
Receiving a Silver Caltrans Partnering Award, the I-201 Pavement and Median Barrier Replacement project was completed two-and-a-half months early and $1.4 million under budget. The award-winning project also boasts zero recordable OSHA safety accidents.
Cutting through the Verdugo Mountain range, I-210 abuts open space and parklands within the Santa Monica Mountains Conservancy Zone just north of Los Angeles.
Serving at the project’s contractor, Security Paving Company, Inc. (SPCI) replaced 6.4 miles of existing pavement with PCC and HMA, as well as a median concrete barrier. Creating complications, the project team was challenged with tight access space and limited right-of-way access. Furthermore, with motorists crossing the heavily travelled corridor at excessive speeds during non-peak hours, worker and public safety posed a major concern.
Weekly progress meetings and on-site field meetings between Caltrans and Security Paving Company, Inc. (SPCI) enabled the team to identify potential problems quickly and find reasonable and economically sound solutions. For example, to meet current safety standards, SPCI needed to upgrade a partially constructed MBG rail to an MGS rail. To mitigate significant cost and schedule delays, the designer, maintenance division, and the manufacturer closely collaborated to develop an amenable solution.
During the project, a dispute arose whether to pin the k-rail dividing traffic. By working together through the Partnering Process, a more productive and less destructive solution was uncovered. Furthermore, by working as a unified team, alternatives were found to reduce long-term ramp closure durations and minimize impacts to local residents and businesses.
Congratulations to the project teams above and the rest of the award-winning projects. According to Caltrans, the Partnering programs these teams implemented were instrumental in producing the following results:
SAFETY: 16 out of 20 Projects had Zero Lost Time Accidents
BUDGET: 15 out of 20 Projects Came Within or Under Budget- Total Savings – $11 Million
SCHEDULE: 19 out of 20 Projects Came in on Time or Early – Total Days Saved -380
These accomplishments are a true-testament to the advantages a well-executed Partnering program provides.
