The Fresno River Viaduct under construction in 2017[1]

The construction of the California High-Speed Rail system is an undertaking by the California High-Speed Rail Authority. The project is expected to span about Шаблон:Convert and will be completed in two phases:

Overview of project segments

Due to the project being only partially funded, the Authority is completing the environmental clearance of Phase 1 and focussing construction activity on the "Initial Operating Segment (IOS)" in the Central Valley. The IOS is intended to be a self-contained and financially self-sustaining high-speed rail system, improving on and partially replacing the existing Amtrak San Joaquins service. As funding becomes available, the Authority plans to extend the system to San Francisco in the northwest, and subsequently southwards to Los Angeles and Anaheim.

The major steps in delivering operational segments of high-speed rail can be characterized as:

  1. Environmental clearance
  2. Design and civil construction
  3. Installation of track and systems
  4. Static and dynamic testing

The following table provides an overview of these steps in each section of the entire project:

Current construction status

Файл:CP1 4 Map.pdf
CASHR initial construction packages in the Interim Initial Operating Segment (Interim IOS).

A December 2023 status summary presentation, which contains extensive status information as well as information about improved management procedures, was prepared for the December 6, 2023 Board Meeting.[2]

In the Central Valley major construction projects are underway. Three separate construction packages total 119 miles of guideway and 93 structures. As of August 2023, 53 miles of guideway are complete, 43 structures are complete, and 32 are underway.[3]

  • Construction Package 1 (CP 1) comprises Шаблон:Convert from Avenue 17 north of Madera to East American Avenue south of Fresno. It includes 12 grade separations, two viaducts, one tunnel, a major river crossing over the San Joaquin River, and the realignment of State Route 99. The contractor is the joint venture of Tutor-Perini/Zachry/Parsons.[4] The design-build contract was signed August 16, 2013.[3]Шаблон:Rp CP 1 is anticipated to be substantially completed in 2026. As of end of October 2023: of 33 structures, by the end of 2023 10 will be underway, and only 15 will remain to be completed; of 32 miles of guideway, 2 miles are completed, 18 are underway, and 12 miles remain; and of 992 utility relocations, 564 have been completed, 250 are in progress, and 178 remain.
  • Construction Package 2-3 (CP 2-3) comprises Шаблон:Convert from East American Avenue south of Fresno to Шаблон:Convert north of the Tulare / Kern County border. It includes approximately 36 grade separations, viaducts, underpasses, and overpasses. The contractor is the joint venture of Dragados USA/Flatiron Construction.[5] The design-build contract was signed June 10, 2015.[3]Шаблон:Rp CP 2-3 is anticipated to be substantially completed in 2026. As of end of October 2023: of 49 structures, by the end of 2023, 16 are complete, 23 will be underway, and only 10 will remain to be completed; of 65 miles of guideway, 33 miles are completed, 16 are underway, and 16 miles remain; and of 701 utility relocations, 493 have been completed, 66 are in progress, and 142 remain.
  • Construction Package 4 (CP 4) comprises Шаблон:Convert adjoining the end of CP 2-3 to the intersection of Poplar / Madera Avenue northwest of Shafter. It includes at-grade embankments, retained-fill over-crossings, viaducts, aerial sections of the high-speed rail alignment, and the relocation of four miles of existing Burlington Northern Santa Fe (BNSF) tracks. The contractor is California Rail Builders, a joint venture of Ferrovial-Agroman West, LLC and Griffith Company.[6] The design-build contract was signed February 29, 2016.[3]Шаблон:Rp CP4 is anticipated to be substantially completed by the end of 2023. As of December 6, 2023 only 400 ft. of guideway remain to be completed.

Per the December 6, 2023 Board Memo: Construction Update: [7]

"Currently, 98% (2,258) of parcels have now been delivered to the design-builder, and the remaining parcels now stands at just over 2% (37).

"CP 1: The Revised Baseline Schedule has been accepted, and all major commercial issues previously reported have now been resolved. The primary risks have been identified and mitigated; however, risks remain that include delays with third-party approvals and design approval.

"CP 2-3: The primary risk areas are ROW acquisitions for utility relocations, delays with third-party design reviews and approvals, and obtaining an agreement from DFJV on the Revised Baseline Schedule. The Authority is proactively managing these risks and working collaboratively with the respective parties to advance a resolution.

"CP 4: All structures are now complete, including the delivery of all right-of-way parcels. There is only 400 feet of guideway that remains in progress due to outstanding land conveyance issues with Canal 9-22. Mitigation efforts include the evaluation of various options to identify a path forward and working closely with the North Kern Water Storage District (NKWSD) to reach a mutual agreement to advance the completion of work in this area."

Per the 2023 Project Status Report (released Mar. 1, 2023):[8]

  • CP1 Seven of eight major commercial issues noted in 2022 Business Plan have resolved, and only Church Avenue remains.
  • CP2-3 Three of four major commercial issues noted in 2022 Business Plan have been resolved, and the last one (Cross Creek) is in arbitration.
  • CP4 The one major commercial issue noted in the 2022 Business Plan has been resolved.
  • Finishing the 119-mile Construction Packages:
    • "The Authority now has over 96% of right-of-way in hand, has completed design of the 119-mile HSR civil infrastructure, and has completed 53% of utility relocations, with another 19% underway. The new estimates for this existing construction work represent updates from major final design elements being incorporated into construction contracts via change orders and updates due to global inflation and new construction schedules – due in part to COVID-19. To complete current civil contracts and related work, $2.2 billion is added to the 2022 Business Plan estimate."
  • New Contracts/Work to Complete Merced to Bakersfield:
    • "The Authority is also looking towards new procurements for civil construction to Merced and Bakersfield, the track and systems work, stations, and finally trainsets. We are already approaching the extensions differently by advancing design to the configuration-level, which is generally about 30 percent, and will procure right-of-way in advance of construction work."
  • Beginning planning work for IOS stations.
  • Extensions of the line from the above central section to Bakersfield and Merced, totaling Шаблон:Convert, are also progressing through advanced design work, right-of-way mapping, and identification of utility relocation work. Construction contracts have not yet been let.
    • Merced to Madera extension (34 miles). Segment begins at R Street in Downtown Merced and concludes at Avenue 19 in Madera.
    • Shafter to Bakersfield (19 miles). Segment begins at southern limit of CP 4 at Poplar Avenue in Shafter and ends at the Bakersfield station at F Street.
  • The Heavy Maintenance Facility (HMF) is proceeding through the planning and approval process.[9]
  • Cost updates for new contracts are:
Файл:2023 119mile cost update.png
Revised cost update for 119 mile segment civil construction per 2023 Project Update Report of $2.2 billion at P65 level. The total cost increase estimate until operational implementation at P65 is $3.7 billion.

"Bookend" investments are also underway to the north and south:

  • The Caltrain electrification "bookend" investment in the Bay Area (as well as grade separations, etc.) is proceeding, and is expected to be completed in late 2024.[10]
  • A "bookend" investment in the "Link US" project (Phase A) will shortly begin construction for Los Angeles Union Station. Phase B still needs to be funded. (There are also other "bookend" investments which are in progress.)[11]

Staged Project Delivery Process and the Project Delivery Decision Committee

On page 6 in the 2023 Project Update Report the Authority describes the Staged Project Delivery process which it is now using.

Associated with this process was an identified need to enhance and supplement the current overview process by establishing a Project Delivery Decision Committee. This is a director-level committee to provide oversight on scope, cost, and scheduling on each project; formally evaluate the most appropriate delivery methods for each project; and recommend the best course of action. It also reviews major project decisions.[12]

History of construction

Historical construction milestones

  • On December 2, 2010, the Authority Board of Directors voted to begin construction on the first section of the system (in the Central Valley).
  • On July 19, 2012, Governor Jerry Brown signed legislation approving construction of the high-speed system.[13][14]
  • On January 6, 2015, the City of Fresno hosted a groundbreaking ceremony to mark the commencement of sustained construction activities.[15]

History of projected construction timelines

The 2008 Business Plan projected that construction for the entire project would be completed by 2030.[16]

The 2012 Business Plan projected HSR service between Los Angeles and San Francisco would not be available until 2029.[17]

The 2016 Business Plan projected:

  • By 2018: The Initial Construction Segment (ICS) would be completed – Шаблон:Convert – Merced to Bakersfield.
  • By 2022: Initial Operating Section (IOS) would be completed – Шаблон:Convert – Merced to Burbank[18]
  • By 2027: Bay to Basin would be completed – Шаблон:Convert – San Jose & Merced to Burbank
  • By 2029: Phase 1 Blended would be completed – Шаблон:Convert – San Francisco to Los Angeles/Anaheim

The 2018 Business Plan projected HSR service between Los Angeles and San Francisco will not be available until 2033.[19]

The 2020 Business Plan projected HSR service between Silicon Valley and the Central Valley would be operational by late 2031, and that service between Los Angeles and San Francisco will be operational in 2033.[20]

The 2022 Business Plan does not have a projected timeline for completion of any of the segments other than the Interim IOS, recognizing that financial constraints make such an estimate unpredictable. Table 5.0 gives estimates of costs to finish the construction in year of expenditure dollars, but assumes that there would be no major delays.[21]

Initial construction approvals

On December 2, 2010, the Authority Board of Directors voted to begin construction on the first section of the system from Madera to Fresno, known as the Initial Construction Segment (ICS). Five "construction packages" are currently being planned for this section. With the Design-Build contractual system the Authority is using, the contractor will be responsible for the final construction design elements, following the guidelines and specifications of the contract. The intent of this (as explained by Dan Richard, chair of the Authority) is to minimize last minute design change orders arising during the construction process (which tend to add to expenses and slow construction).[22]

On December 20, 2010, due to the infusion of an additional $616 million in federal funds reallocated from states that canceled their high-speed rail plans, the initial segment of construction was extended to Bakersfield. Another $300 million was reallocated on May 9, 2011, extending the funded portion north to the future Chowchilla Wye (where trains can be turned).[23]

In September 2012, the Obama administration gave California's high-speed rail project the green light to streamline the permitting process for the Шаблон:Convert section of the project which starts just north of Fresno in Madera County and runs south to Bakersfield.

On August 12, 2014, the federal Surface Transportation Board approved the HSR route from Fresno to Bakersfield. This was the final approval needed before beginning construction.[24]

Also, on December 15, 2014, the federal Surface Transportation Board determined (using well-understood preemption rules) that its approval of the HSR project in August "categorically preexempts" lawsuits filed under the California Environmental Quality Act (CEQA). This cleared the last obstacle before construction could begin.[25] However, this supposition is still being tested in the California courts in a similar case, Friends of Eel River v. North Coast Railroad Authority.[26]

On June 10, 2015, the Authority authorized a "Rail Delivery Partner" contract to be negotiated and signed by the CEO, valued at up to $700 million, for services through 2022. This is a successor to the support provided by the current Project Management Team contract. The RDP will provide engineering and management services to see the project from a planning mode into a construction mode. The RDP partnership under the lead of Parsons Brinckerhoff includes Network Rail Consulting (the international consulting arm of the UK rail authority) and LeighFisher (a global management firm with extensive experience in infrastructure and advisory services). The other partnership competing was under Bechtel Infrastructure Corporation.[27]

Awarding initial construction packages (San Joaquin Valley segments)

CP1. On August 20, 2013, the joint venture of Tutor Perini/Zachry/Parsons executed a design-build contract for the initial Madera to Fresno segment, about Шаблон:Convert long. The contract is valued at approximately $985 million, plus an additional $53 million in provisional sums.[28] Construction was originally expected to begin in 2013, but was delayed by the slow pace of property acquisition.[29]

CP2-3. Dragados of Spain, with Flatiron West of San Marcos, and Jacobs Engineering of Oakland, won the bid for the second design-build construction package on December 11, 2014. Dragados/Flatiron/Jacobs submitted a bid of $1,365,335,890 to design and build the Шаблон:Convert stretch from the south end of Fresno to near the Tulare-Kings county line and was deemed the "apparent best value" bidder by the Authority.[30] The winning bid came well below the range of $1.5 billion to $2 billion that was forecast by engineers and consultants working for the rail authority due to their innovative plan for cutting-and-filling instead of more expensive construction alternatives.[22] This plan however was deemed impossible due to soil and hydrological conditions on site and the plan was reverted to its original designs.

CP4. Five construction teams competed for this Шаблон:Convert segment.[31] This section was estimated to cost $400–500 million.[32] In January 2016 the apparent best value bid of $347.5 million (about $50 to $150 less than the estimated cost) was received from California Rail Builders (a consortium led by Ferrovial Agroman US Corp, an American subsidiary of Spain's Ferrovial S.A., also including Eurostudios, a Spanish engineering firm, and Othon Inc., a Houston-based engineering and environmental consulting company).[33] The California Rail Builders bid was $347.5 million. The contract awarded includes an additional $107 million for utility relocation costs for electric, gas and communication lines.[34] This project has had the least issues out of all of the current construction packages and is set to be completed by late 2023.

This package was shortened by about Шаблон:Convert to a length of Шаблон:Convert due to disputes with the cities of Bakersfield and Shafter. The construction segment now ends on the north side of Shafter due to the need to negotiate routes through Shafter and northern Bakersfield. The agreement between the cities and the Authority gave the parties until January 2016 to come up with the new alignment.[35] The Poplar Avenue to Bakersfield Locally Generated Alternative was signed by the Authority's CEO on October 31, 2019, and as of May 2022, geotechnical work has begun taking place.

Extending initial San Joaquin Valley construction

In August 2022, contracts for advanced design work, right-of-way mapping, and identification of utility relocation work in the Merced-Madera and the Shafter to Bakersfield (Locally Generated Alternative) segments were approved.[36] Construction will only begin once the design and land has been acquired. This reflects a change from the approach taken with the first four construction packages. Utility relocations will also begin as land is purchased to speed the construction process and avoid delays.

The Merced to Madera extension design contract ($41 million) was awarded to Stantec Consulting Services Inc., for approximately 33.9 mi. with 40 structures. The Shafter to Bakersfield (Locally Generated Alternative) extension design contract ($44.9 million) was awarded to HNTB for approximately 18.5 mi. with 31 structures. These design contracts are expected to last into 2024.[37]

Other San Joaquin Valley constructions

The design contract for the central valley stations was awarded on October 20, 2022.[38]

In addition, a large parcel will be needed for a rail yard, train sheds, machine shops, and other buildings for work on the tracks and trainsets in the Heavy Maintenance Facility (HMF). The counties of Fresno, Madera, Merced, Kings, and Kern all have expressed some interest in being selected for the site, since it is expected to provide up to 1500 good paying jobs. Per the May 2023 CEO Report to the Board, eleven potential sites have been identified in these four counties, and an architectural and engineering contractor will be selected (approximately by October 2023) for a two-year contract to evaluate the properties, develop the necessary environmental documents, and obtain necessary approvals. In 2025 staff will provide the Board with their preferred alternative for their decision.

Statewide connectivity projects

According to the Authority: "Connectivity or ‘Bookend’ Projects refer to the billions of dollars in infrastructure investment throughout the state that are part of the California High-Speed Rail system. These funds will strengthen and improve existing rail networks, while also connecting them with California's future high-speed rail system. Senate Bill (SB) 1029[39] passed by the California Legislature and signed by Governor Brown in July 2012, invests almost $2 billion from the Safe, Reliable, High-Speed Passenger Train Bond Act for the 21st Century (Proposition 1A) into transit, commuter, and intercity rail projects across the state. This funding leverages approximately $5 billion in additional funding for these projects."[40]

Major "bookend" investments are underway to the north and south:

  • The Caltrain electrification "bookend" investment in the Bay Area (as well as grade separations, etc.) is proceeding, and is expected to be completed in late 2024.[41]
  • A "bookend" investment in the "Link US" project (Phase A) will shortly begin construction for Los Angeles Union Station. Phase B still needs to be funded.[11]

Other connectivity projects partly funded by the Authority are:[40]

  • Bay Area Caltrain Advanced Signal System (CBOSS/Positive Train Control)
  • Bay Area Central Subway
  • Bay Area Maintenance Shop and Yard Improvements
  • Bay Area Millbrae Station Track Improvement and Car Purchase
  • Central Valley Sacramento Intermodal Facility High-Speed
  • Central Valley San Joaquin Corridor, Merced to Le Grand Segment 1
  • Central Valley Stockton Passenger Track Extension
  • Central Valley/Los Angeles Metrolink High-Speed Rail Readiness Program
  • Los Angeles Metrolink Positive Train Control
  • Los Angeles Positive Train Control, Los Angeles to Fullerton Triple Track
  • Los Angeles Positive Train Control, Moorpark to San Onofre

Station construction details

Five stations are planned for the Initial Operating Segment (IOS). The design contract for the central valley stations was awarded on October 20, 2022. This contact is for initial planning, including utilities management; a follow-on contract will be necessary for detailed station construction plans.[97] The number of stations on the completed system was limited by Proposition 1A to 24.

At the start of operations of the Interim Initial Operating Segment (Interim IOS, Merced to Bakersfield) there will be 5 stations. These stations are discussed in the 2023 Project Update Report on pages 12–15. The report also has a timeline (on pages 8–9) that shows station construction is anticipated to commence in mid-2026, and finish in mid-2029.
