Sunnyvale Downtown Streetscape

in ,

The goal of this improvement project was to enhance roadway segments and to implement streetscape design themes in order to unify the downtown commercial and residential areas. The scope of the project included the installation of wider sidewalks, street trees with grates, irrigation systems, street lighting, street furniture, and bicycle parking facilities. Roadway pavement, traffic loop detectors, and roadway striping were also installed. The design included the necessary conform area between the existing grade and the new back of sidewalk.
Phase I improvements are located along Sunnyvale Avenue between Iowa Avenue and Evelyn Avenue. Phase II improvements are located along Iowa Avenue between Sunnyvale Avenue and Mathilda Avenue.
Prior to construction, HMH provided mapping and legal documents to the City that allowed for the acquisition of right-of-way necessary to install the proposed improvements.

Caltrain Santa Clara Station PUC Extension

in

The Santa Clara Valley Transportation Authority extended the recently constructed Caltrain tunnel, which now terminates at the center platform of the Santa Clara Caltrain Station. This tunnel extension is underneath the tracks of Union Pacific Railroad and includes a 200’ long ramp at the east end, connecting pedestrians and bicyclists from Brokaw Road to Railroad Avenue. The undercrossing extension is constructed with the cut and cover method, which requires a temporary shoe-fly to maintain the existing rail operations.
HMH provided base mapping services including supplementary field surveys, utility investigation and on-site utility locating. Preliminary engineering, including grading and drainage design was also prepared by HMH.
One of the project challenges was to protect the portal opening to the undercrossing from inundation from a major flood event. This was accomplished by elevating the ramp entry area at Brokaw Road above anticipated flood levels such that storm water would release through overland flows without flooding the tunnel.
The project team produced the Preliminary Engineering plans on time and within the approved budget.

U.S. 101 Tully Road Interchange

in ,

HMH led this critical Proposition 1-B bond-funded project for major improvements to U.S. 101 between State Route I-280/I-680 and Yerba Buena Road.  Working closely with Caltrans, VTA and the City of San Jose, HMH developed a multi-phase implementation approach by preparing a Project Study Report/Project Report (PSR/PR) with environmental clearance to add a southbound lane, modify interchanges at U.S. 101/Tully Road and Capitol Expressway to partial cloverleaf configurations, with auxiliary lanes and ramp modifications.
HMH completed Plans, Specifications and Estimates (PS&E) for Phase 1 including reconstruction of the U.S. 101/Tully Road freeway interchange; the addition of a southbound travel lane and a new auxiliary lane from Tully Road to Capitol Expressway.  Because of the funding priority, great emphasis was placed upon schedule delivery and budget accountability.  HMH responded with high-quality PS&E ready for advertisement on schedule by Caltrans.  Bids were received in July 2010 for $23.5 million, almost 34% under the estimate.
HMH services also included control surveys and aerial topographic mapping according to Caltrans A, B and C submittal procedures, preparation of mandatory and advisory design exception fact sheets, geometric approval drawings, utility coordination, and technical studies for the State CEQA Initial Study/ Negative Declaration and Federal NEPA Categorical Exclusion Environmental Clearances.  HMH met the accelerated schedule and budget requirements with adjustments for scope changes related to VTA’s multi-modal approach.

U.S. 101 Bailey Avenue Interchange

in

The Route 101/Bailey Avenue Interchange was part of the Bailey Avenue Extension project, a $45 million improvement to provide access to the North Coyote Valley Campus Industrial Area in South San Jose. The City of San Jose and the developer, CVRP, jointly sponsored the project using a combination of STIP funds and local funds.
Working closely with the City of San Jose, Caltrans, VTA and local developers, HMH designed the U.S. 101/Bailey Avenue Interchange to provide access to the North Coyote Valley Campus Industrial Area in south San Jose. This freeway interchange includes a 4-lane highway overcrossing structure and 2-lane ramps in all quadrants including a loop ramp for the northbound on-ramp. In addition to the freeway interchange, the Bailey Avenue Extension includes a 500-foot long 6-lane bridge across Coyote Creek and a grade separation over the UPRR tracks at Monterey Road, with connector ramps between Bailey Avenue and Monterey Road. The project was built in multiple phases to take advantage of the availability of State Transportation Improvement Program (STIP) funds, California Public Utility Commission (CPUC) Grade Separation funds and local agency funding.
In addition to the preparation of Plans, Specifications and Estimates (PS&E), HMH performed all right-of-way design engineering and topographic surveys for the project’s various segments. We performed control surveys, boundary resolution and aerial topographic mapping to Caltrans standards, along with supplemental ground surveys for conform elevations and utility features.
HMH prepared legal descriptions & plat maps and coordinated inter-agency right-of-way transfers involving Caltrans, City of San Jose, Santa Clara County Parks and Santa Clara County Roads & Airports Departments. HMH assisted our clients in acquiring right-of-way from three private owners, all without eminent domain. At the completion of the right-of-way engineering process, a Record of Survey was prepared and filed for recordation to incorporate the official monumentation of the centerline for the new Bailey Avenue alignment from west of Monterey Road to east of U.S. 101.
HMH devised a construction packaging strategy to successfully maximize use of available public agency and private developer funds.
HMH prepared right-of-way documents (e.g. Record of Survey) and assisted our clients in facilitating the acquisition and land transfers among Caltrans, the City and two County agencies.
VTA staff complimented HMH on their performance “on time and within budget” and with minimal change orders for the $15 million freeway interchange contract.

ACE Charter School

in ,

The ACE Charter School proposed to develop a new middle school campus at 625 South Sunset Avenue in San Jose on a 1.94 acre site adjacent to Cesar Chavez Elementary School in the Mayfield neighborhood. The site was a portion of surplus land owned and leased from Alum Rock Union School District (ARUSD).
The project consisted of the construction and operation of a school campus consisting of approximately 22,080 square feet of building space in 18 classrooms, an administration building and associated parking. There were plans to build a multi-purpose room in the future, contingent on a future capital campaign to commence in 2012. All of the buildings, except the future multi-purpose building, were prefabricated modular buildings.

San Jose International Airport

in

HMH prepared a master utility plan for the San Jose International Airport in preparation for the Airport Improvement Program. The plan included utility mapping of the entire airport and surrounding area, encompassing the area bounded by Highway 101, Highway 87, Highway 880, and Coleman Avenue/De La Cruz Boulevard. Critical schedule and budget milestones were maintained for use in development of the new terminal concepts. Research was performed by obtaining several thousand record drawings from airport archives, city agencies, and utility companies.
Over two miles of road was designed to accommodate projected traffic demands and to transition the flow of traffic onto an efficient one-way loop network. A ground transportation center was constructed at Terminal A for mixed transit use including bus, rental car shuttles and taxis. A second transportation center was constructed at Terminal C along with several taxi staging areas. Road width varied from one to six lanes. Value engineering allowed the project to meet strict budget constraints. HMH played a key role in coordination with the Master Plan Team, Airport Operations, Airport Facilities, subconsultants, and utility companies
