BROADWAY ROAD IMPROVEMENTS PROJECT PROMOTES GREEN LIVING THROUGH ALTERNATE MEANS OF TRAVEL

Project Background: The Pedestrian and Bicycle Improvements - Broadway Road from Mill Avenue to Rural Road project’s main challenge was to provide an enhanced experience for pedestrians and bicyclists traveling through one of the busiest vehicular traffic roadways in Tempe. This one-mile corridor is exceptionally congested due to its close proximity to multiple educational facilities, dozens of businesses, and hundreds of residences. In February of 2015, Achen-Gardner was selected using the Design-Bid-Build delivery method to assist in removing one of three eastbound lanes of vehicular travel and adding both an eastbound and westbound bicycle lane in conjunction with wider sidewalks along the entire length of the road.

Project Scope: This project included the demolition and removal of 9,100 square yards (SY) of asphalt concrete pavement, 13,936 linear feet (LF) of curb and gutter, 51,412 square feet (SF) of concrete sidewalks and driveways, 18 concrete catch basins along with interconnecting pipe, and the relocation and/or removal of hundreds of native trees. 

Once all the removals were complete, crews began the new construction of:

·      More than 2,000 tons of asphaltic concrete

·      3,628 SY of mill and replace

·      26,583 SY of slurry seal

·      9,028 LF of vertical curb and gutter

·      5,254 LF of concrete single curb, 1,687 LF of roll curb, 911 LF of ribbon curb

·      45,429 SF of ADA compliant concrete sidewalk, 8,188 SF of ADA compliant commercial business concrete entrances, 6,720 SF of ADA compliant residential concrete entrances, 28 ADA compliant concrete ramps

·      3,005 SF of decorative stamped pavement

·      27,980 LF of asphalt striping

·      34,837 SY of decomposed granite

·      11,132 LF of irrigation piping

·      1,000 LF of landscaped median islands

·      4,068 LF of wet utility pipe

·      18 concrete catch basins

·      8,225 LF of electrical conduit

·      20,061 SF of artistic screen wall

Teamwork, Stakeholder Access, and Project Phasing: With a large amount of complex work to complete in a relatively short period of time, Achen-Gardner (General Contractor) coordinated with the City of Tempe (Owner), Parson Brinckerhoff (Design Engineer), and all project stakeholders in planning the work to ensure the construction activity had minimal impact on area residents, businesses, and the travelling public. Every business entrance and residential driveway was constructed in halves or thirds to maintain access, and all of the businesses had one entrance and one exit throughout the duration of the project. Also, project phasing and a detailed traffic control plan provided room for pedestrians and bicyclists to move through the corridor.

The project was broken up into the following phases:

·      Phase 1A – North side of Broadway Road from Rural Road to the pedestrian crosswalk

·      Phase 1B –North side of Broadway Road from the pedestrian crosswalk to College Avenue

·      Phase 1C –North side of Broadway Road from College Avenue to Mill Avenue

·      Phase 2A –South side of Broadway Road from Rural Road to the pedestrian crosswalk

·      Phase 2B –South side of Broadway Road from the pedestrian crosswalk to College Avenue

·      Phase 2C - South side of Broadway Road from College Avenue to Mill Avenue

·      Phase 3A – Median islands from Rural Road to College Avenue

·      Phase 3B – Median islands from College Avenue to Mill Avenue

·      Phase 4 – Intersections of Broadway Road and Mill Avenue, College Avenue, and Rural Road

In conjunction with this detailed phasing plan the Achen-Gardner team spent more than 650 man-hours completing daily lane closure adjustments prior to commencement of the morning and afternoon commutes in an effort to maintain two lanes of travel in the direction of the peak flows.

Streetscape Features and Project Success: In addition to new sidewalks, bike lanes, and landscaped medians, this project has many notable features including more than 20,000 SF of artistic screen walls. The walls (8-10 feet tall) were constructed along the north side of Broadway Road and replaced the sour orange trees that once lined the roadway. The walls not only separate the adjacent Broadway Lane frontage road and neighborhoods, but also feature public art titled "Hedgerow", designed and installed by local artists Laurie Lundquist and Rebecca Ross. The privacy walls were cleverly enhanced with 123 steel "tree profiles" and 1,250 square "pixels" in various hues of green and orange to create the sense of a hedge of orange trees and pay homage to the trees that are now gone. Shadow effects are created by the sun during the day and streetlights at night, creating continually evolving visual interest. The artists were also able to enhance the aesthetic experience of the adjacent block walls by incorporating specific block patterns in its design. Continuing the orange tree motif, Morse code patterns spell out "orange trees" and "blossoms" in repeated sections.

Other notable aesthetic improvements include the decorative stamping of crosswalks at the intersections of Mill Avenue, Rural Road, and College Avenue, as well as at residential parking stalls along Broadway Lane, and in between the median islands to on Broadway Road. Additional features include a new metered pedestrian crossing east of Sierra Vista Drive which also has decorative stamping, clearly delineated eastbound and westbound bike lanes, increased sidewalk widths from 4 feet to 8 feet wide, major improvements to nighttime illumination of the corridor, and vast improvements to the landscaping throughout the entire corridor with the planting of plants native to Arizona.

VALENCIA ROAD IMPROVEMENTS PROJECT PROMOTES TRANSPORTATION THROUGH FLOODPLAIN

Project Background: The Pima County Department of Transportation (PCDOT), in conjunction with the Regional Transportation Authority's (RTA) Roadway Improvement Plan, is working to improve the Valencia Road Corridor from Mark Road to Ajo Highway. The RTA's Roadway Improvement Plan, which was approved by Pima County voters in May 2006, proposed that this existing two-lane arterial be designed as a "desert parkway" and provide multi-modal transportation improvements.

In October of 2014, Achen-Gardner was awarded the Valencia Road – Mark Road to Wade Road improvements project using the Design-Bid-Build delivery method. This 2.5-mile, two-lane roadway experienced constant flooding and closures during the monsoon season. The project not only included roadway widening but also significant drainage improvements. The final scope of work consisted of constructing a four lane arterial roadway with a raised median along the Valencia Road alignment from Star Diamond Place (west boundary of the project approximately 1,800 feet west of Wade Road) to Camino Rancho and a five lane arterial roadway from Camino Rancho to the east boundary of the project (approximately 1,600 feet west of Mark Road). This project included importing more than 100,000 cubic yards of material to raise the roadway between one and four feet and installing six cast-in-place concrete box culverts to control and direct water flow in the Black Wash floodplain.

Project Execution and Phasing: The Valencia Road improvement project was unique in that almost all fundamental elements of roadway construction were involved including earthwork, concrete structures, paving, and new traffic signal installation. All of this work needed to be completed while maintaining two-way traffic on Valencia Road, which is a major arterial for commuters and prone to frequent traffic jams during peak hours. In addition to the high volume of traffic, this section of Valencia Road experiences several closures every year due to storm water.

Based on the plans and specifications that were developed by HDR (Design Engineer), it was determined that there was enough room to widen Valencia and install the required drainage and utility improvements in four phases. These phases were broken up into the following areas:

·      Phase 1 – South side of Valencia Road from the East Match Point (approximately 1,600 feet west of Mark Road) to Camino Verde

·      Phase 2 – South side of Valencia Road from Camino Verde to Star Diamond Place

·      Phase 3 – North side of Valencia Road from the East Match Point (approximately 1,600 feet west of Mark Road) to Camino Verde

·      Phase 4 – North side of Valencia Road from Camino Verde to Star Diamond Place

Phasing the project in this way allowed for the crews working on the box culverts to proceed in front of the roadway construction crews while also allowing traffic to flow in both directions on Valencia Road. In some areas, the new section of Valencia Road was four feet higher than the existing road, causing traffic to be on the top of an embankment with concrete barriers separating them from the work below. Basically, the south half of Valencia Road could be completed while traffic remained on the existing two-lane roadway to the north. Once the new road section was completed in each phase, traffic was shifted so that they remained unaffected by adjacent construction activities.

As mentioned earlier, this section of Valencia Road was susceptible to flooding and restricted or shut down several times every year by monsoons and large rain events. The project team is proud to have completed this entire project without having to close the roadway in any areas due to flooding.

Working with Stakeholders: In addition to Valencia Road being used as an artery for commuters, the Casino Del Sol Resort was located within the project limits and required coordination throughout the project. Casino Del Sol is a large attraction for locals and visitors and remained busy throughout the year. Needless to say they were a major project stakeholder. Part of the execution plan in this area involved coordination with the Casino on keeping their main entrance accessible at all times. As part of this project, the main entrance was enhanced with a new signalized intersection and the branding of Casino Del Sol Drive. The project team met with respresentatives from Casino Del Sol to coordinate timing and execution of these improvements to minimize impacts. It was decided that during the Casino’s planned four-day shutdown that Achen-Gardner would implement a full closure of the entrance and complete the work in that area. The Casino commenced their shutdown, and the work was completed within the required time frame.

Teamwork and Project Success: The Valencia Road improvement project marked Achen-Gardner’s first project with the PCDOT. This project began with a partnering meeting that included major stakeholders, PCDOT representatives, and field inspection personnel. From this meeting, it was decided that the project team would work, free from personal agendas and with open minds, to solve field issues and coordinate with stakeholders to deliver a high-quality project for the taxpayers of Pima County.

Throughout the project, Achen-Gardner and Pima County partnered on issues to come up with amicable solutions as well as implemented value engineering ideas. For example, the work on Camino Verde, north of Valencia Road, was initially scheduled to take a month to complete and the phasing would have resulted in prolonged negative impacts to the travelling public. Achen-Gardner requested a complete closure of the roadway for two weeks in order to complete the work and minimize public inconvenience. Pima County granted the closure with the stipulation that the two-week schedule be met by any means necessary. This section of roadway was delivered on time, as promised, even with the excavation and replacement of approximately 1,000 cubic yards of unsuitable subgrade material which delayed the already aggressive two-week schedule by one day.
