Caltrans District 8 On-Call Contracts

The Inland Empire features a sprawling system of highways providing interregional and interstate travel. Advanced Civil Technologies is delivering task orders to maintain and upgrade these highly traveled routes.

As one of the largest districts in the state, Caltrans District 8 oversees a vast network of highways throughout the counties of San Bernardino and Riverside. Many Inland Empire residents depend on this network to travel between communities. Additionally, interstates such as I-15 and I-10 are utilized heavily by both travelers and commercial traffic alike. Both counties are experiencing significant growth as Californians seek affordable housing, and traffic demand is forecast to increase greatly. To keep up with demand, Advanced Civil Technologies has supported Caltrans in the delivery of numerous task orders, preserving the quality of District 8’s transportation infrastructure. Many of these task orders have been delivered on expedited schedules, requiring close coordination with the District.

Median Regrading on I-40

To reduce the number and severity of run-off-road accidents on I-40 in San Bernardino County, Caltrans has proposed to regrade the highway median from a 6:1 slope to a 10:1 slope or flatter. Advanced Civil Technologies supported the development of the PA/ED and PS&E phases for the regrading, which will be implemented for 25 miles from Fort Cady Road to Crucero Road. The project will also extend 54 culverts to accommodate the regrading as well as improve the existing CHP crossings in the median. Our team was responsible for providing grading plans for the easterly end of the project, drainage plans for 27 cross culvert locations, the preliminary drainage report, Storm Water Data Report (SWDR), water quality technical memo, and TMP data sheet.

 The project team worked to address cultural and drainage issues over the course of development. Several cultural sites exist within the project area, and the team ensured that these sites will not be impacted. Close coordination also took place between the grading and the drainage teams to ensure that existing hydrology patterns will be maintained and prevent culverts from overflowing. The project was delivered on an expedited schedule.

I-10 Bridge Scour

The Orris Ditch Bridges and Aztec Ditch Bridges in Riverside County have been identified as scour critical due to inadequacy of existing Rock Slope Protection at the structure abutments. Advanced Civil Technologies led the preparation of a Project Initiation Report (PIR) to preserve the structural integrity of all four bridges by reconstructing the Rock Slope Protection. Additionally, the project will widen all four bridges so bridge rails can be upgraded to current standards.

SB I-15 to EB I-10 Connector Seismic Retrofit

In San Bernardino County, the SB I-15 to EB I-10 connector has been identified as structurally vulnerable to high ground shaking conditions, requiring retrofitting to maintain the integrity of the connector. Advanced Civil Technologies led the preparation of a PIR that proposed several retrofitting improvements in addition to upgrading the existing barrier rail to meet current standards. Close coordination was required with Caltrans DES – Office of Bridge Design South.

I-10 Pavement Rehabilitation

To maintain ride quality on I-10, Advanced Civil Technologies prepared a PIR for pavement rehabilitation from the San Bernardino/Riverside County line to Brookside Avenue in Riverside County. The pavement design of this rehabilitation is forecast to have a life span of 40 years. Additionally, the project will replace outside shoulders, replace the median barrier, upgrade sign panels to the current standard, upgrade curb ramps to be ADA compliant, and incorporate roadside safety elements.

SR-60 Ramp Improvements

High traffic volumes are regularly contributing to congestion on SR-60. To address these volumes, ramp metering equipment is proposed for several interchanges to regulate the flow of entering traffic. Advanced Civil Technologies led the preparation of a PIR to install ramp meters at the interchanges of Mission Boulevard, Country Village Road, Pyrite Street, Valley Way/Byrne Road, Pedley Road, and Main Street. Additionally, the WB on-ramps at Mission Boulevard, Country Village Road, Pyrite Street, and Valley Way will be widened to two lanes. The project will also install two pan-tilt-zoom cameras at each signalized ramp intersection and upgrade curb ramps to be ADA compliant.

SR-18 Culvert Rehabilitation

Caltrans has proposed rehabilitation efforts to address the deterioration of 135 culverts along SR-18 in San Bernardino County. Advanced Civil Technologies prepared a Supplemental PIR to rehabilitate these culverts between the SR-330 junction and the SR-38 West junction. The rehabilitation will utilize various strategies such as cure in place, clearing of debris, and slip lining. 11 culverts will also be completely replaced. In addition, the project proposed to implement a new wireless Changeable Message Sign (CMS) and Rock Slope Protection where needed.

CMS Upgrades on Multiple Routes

Caltrans has identified 21 CMS in Riverside County as being critically degraded, preventing travelers from clearly reading messages. Advanced Civil Technologies prepared a PIR that proposed upgrades to restore readability and make the signs compliant with current standards. These upgrades will provide feedback from each sign directly to the appropriate Transportation Management Center, allowing staff to know the exact message being displayed on the sign. Additionally, the project will replace eight single post sign structures to meet current design standards. Finally, Maintenance Vehicle Pullouts will be introduced to five sign locations.

I-15 Auxiliary Lane Widening

In the City of Temecula, I-15 experiences regular congestion during both peak hours and weekends, as it is the only major freeway that connects the counties of Riverside and San Diego. Advanced Civil Technologies prepared a PIR for the construction of three auxiliary lanes on I-15 throughout the City. Additional improvements include bridge widening, ramp widening, safety upgrades, culvert rehabilitation, and lighting rehabilitation. The PIR required delivery on an expedited three-month schedule in close coordination with Caltrans District 8 functional units, allowing the project to meet deadlines for the 2020 SHOPP cycle.
