OPENING STATEMENT OF HON. JOHN MCCAIN, U.S. SENATOR FROM ARIZONA The CHAIRMAN. Good morning. In an effort to fulfill our Commit- tee’s many duties, we are continuing to conduct hearings on legisla- tion and to work to move bills through the legislative process. We also conduct oversight hearings on Federal programs under our ju- risdiction, as well as on issues of public concern that have been brought to the Committee’s attention. Today’s hearing is designed to take a careful and in-depth look into the Boston Central Artery/Tunnel project, the biggest, most costly public works project in U.S. history, and commonly referred to as the Big Dig. This project has suffered from gross mismanage- ment and what appears to have been a complete lack of critical Federal oversight. As such, it has experienced billions of dollars in cost overruns. The Central Artery/Tunnel project was originally estimated to cost $2.5 billion in 1985. Today, it is estimated to cost U.S. tax- payers a staggering $13.6 billion. Almost daily, the Boston Globe or the Boston Herald publish a new and more embarrassing Big Dig story than the previous day’s expose´, noting the project’s mis- management and many cost overruns. This Committee needs to know what assurances we have that Federal and State highway officials responsible for overseeing this project finally have had their wake-up call. It is my hope that this hearing will enable us to explore the complete and utter failure of the parties involved in this immense multi-billion dollar transpor- tation project, including Federal and State officials and project managers. We must ensure that this project’s mismanagement and oversight neglect are a thing of the past. (1) VerDate Apr 24 2002 08:01 Jun 10, 2003 Jkt 080706 PO 00000 Frm 00005 Fmt 6633 Sfmt 6633 S:\WPSHR\GPO\DOCS\80706.TXT SCOM1 PsN: CAROLT 2 It is also my hope that the witnesses, each of whom is critically involved with the Big Dig project, will provide the Committee with their candid views on their role in the project and their individual perspectives concerning how and why the project’s cost have sky- rocketed. I also encourage each witness to offer specific suggestions on what actions Congress, the administration, State officials and project contractors should undertake to preclude future mis- management of this or other federally funded transportation projects. One area I would like to explore in some detail with the Sec- retary is the outstanding Federal financing obligation to the Cen- tral Artery/Tunnel project. While some Federal Highway Adminis- tration (FHWA) officials contend that the Federal funding level is capped, I am not convinced. There is no statutory cap on the Fed- eral funding share for the project, nor, to my knowledge, is there a written agreement signed by the State and the FHWA capping the Federal funding share for the project. I fear that as of today, we really still do not know the final price to America’s taxpayers. Further, I am not confident in the FHWA’s ability to fulfill its stewardship responsibilities over the expenditure of American’s gas tax dollars. Last year, this Committee spent a considerable amount of time on another issue that highlighted the FHWA’s poor stew- ardship—truck safety. In many meetings on truck safety, we re- ceived nearly unanimous views by a wide range of interested par- ties that the FHWA lacked leadership in its safety enforcement ef- forts. Many felt that the FHWA’s poor leadership was attributable to its more demanding role in overseeing the multi-billion dollar Fed- eral highway construction program. Ultimately, we took away FHWA’s motor carrier safety jurisdiction in an effort to improve truck safety. Perhaps the FHWA’s problems stem more from poor performance generally rather than from its oversight responsibility for the high- way funding program. If FHWA wants the Congress to permit it to continue to have any Federal responsibilities, it had better re- form itself immediately. Much of the public attention on the Big Dig in recent months stems from the independent audit work carried out by the Depart- ment of Transportation

BRENNER Some new computer applications are being developed for and Roule IA applied to the construction planning and traffic studies associated with the design of the Central Artery and Third Harbor Tunnel in Boston. This project is one of the most massive and complex urban highway projects in the country. It features an immersed­ tube harbor tunnel, depression of the downtown expressway in a cut-and-cover tunnel without interrupting service on the existing overhead viaduct, major new or revised urban interchanges, and long-span river crossings. The construction site, with its old exist­ ing and historic buildings and subways, permits limited clear­ ances, posing formidable challenges to engineers planning the work. The computer applications described include computerized composite mapping for archeological planning; analysis of mul­ tilevel curved-girder viaducts; transportation forecasting using highway network models; planning associated with the construc­ tion of the depressed Central Artery tunnels; and computer-aided 1-90 planning and mitigation measures for underpinning, protection of a subway tube, and other construction problems.

  • A Big Dig Cost Recovery Referral: Dewey Square Air Intake Structure
    Office of the Inspector General Commonwealth of Massachusetts Gregory W. Sullivan Inspector General A Big Dig Cost Recovery Referral: Dewey Square Air Intake Structure March 2005 March 2005 Dear Chairman Amorello: I am forwarding for your review the most recent findings from my Office’s continuing review of potential Central Artery/Tunnel Project (Project) cost recovery cases. These findings refer to poor construction management by the joint venture of Bechtel/Parsons Brinckerhoff (B/PB) and poor design work by the section design consultant for the C18A2 - Air Intake Structure contract at Dewey Square, the joint venture of Weidlinger Associates Inc. and Edwards and Kelsey Inc. (WEK). Specifically, my Office found more than $1 million in potential cost recovery items against both B/PB and WEK. These items include poor design and construction coordination, failure to meet building codes, poorly designed rooms and walls, improperly sized doors and specifications for materials that did not exist. I recommend that the matter discussed in this report be referred for cost recovery and that B/PB and the section design consultant be pursued for their share of these cost increases. My staff is available to assist you in any continuing examination of this or any other issue. Sincerely, Gregory W. Sullivan Inspector General cc: Attorney General Thomas F. Reilly This page intentionally left blank. The Contract The C18A2 - Air Intake Structure (AIS) contract is a three-story, 23,000-square-foot mechanical support building placed atop the existing Dewey Square Tunnel at the juncture of Atlantic Avenue and Congress Street. The main purpose of the AIS is to house two large air intake fans to supply fresh air to the rehabilitated Dewey Square Tunnel beneath it.
