Sewage Transfer

Two drives totalling 8 km using two Lovat RME 131SE earth pressure balance machines with mixed face cutting heads capable of operating in open or EPB mode. First drive 4.2 km through predominantly chalky formations with flint content of 5% to 60%; dense calcareous sands, gravels and shelly beds; and very stiff clay with silty, sandy composition. Second drive 3.8 km through chalks with flint content of 5% to 14.4%. Both drives beneath water table at average depth of 21m. Nov 1998. $40 million transfer tunnel nearly complete, with overall contract completion scheduled for January, 2001. At the mid point of the 8 km-long, 2.85 m i.d. tunnel two 7 m-diameter drive shafts lined with pre-cast concrete segments were sunk in chalk using the dry caisson technique and local dewatering. Reception shafts 25 m-deep x 6 m-diameter were sunk at Budds Farm by dry caisson in chalk with flints, and 35 m-deep x 6 m-diameter at Eastney by wet caisson in sands, silts and clays, and a 10 m-diameter pumping shaft has also been built at Eastney. Lovat 3.36 m RME131SE series 18900 EPB has completed and has been upsized and transferred to Cork ie/15, while sister machine series 18800 EPB has 200 m to go to breakthrough. Six-piece bolted, trapezoidal, segmental, steel fibre reinforced tunnel lining rings, nominally 1 m-long, supplied by Macrete of Northern Ireland.

Connector Sewer

$82 million contract awarded by Yorkshire Water to Miller Civil Engineering and Birse Construction joint venture for 10.5 km tunnel, 3.6 m diameter and some 22 m deep with 10 shafts to connect sewers in west and east Hull passing beneath the river, the marina and the docks. Two new Lovat 4.24 m mixed-face TBMs will bore through alluvial sands, glacial clays and tills, silts, sands and gravels with groundwater pressures of 1.9 to 2.3 bar. Maximum cover 16 m and minimum radius 300 m. Three sections to be bored: 5.5 km, 3.33 km and 1.78 km. Machines powered at 672 kW and can run in open or closed mode. Six-piece 3.6 m i.d. segmental trapezoidal lining in rings of 1 m width. March 1998. Ten 25 m-deep shafts constructed as jacked wet caissons using Charcon segments. Two identical Lovat mixed face EPBs delivered October, 1998. Bore diameter 4.24 m, maximum thrust 2,400 t with 672 kW cutterhead power through ten variable displacement hydraulic motors. Six-piece Charcon trapezoidal segmental lining in 1.0 m rings of 4.1 m outside diameter and 3.6 m internal diameter. Schoma locomotives and UMD rolling stock. Sept 1999. Collapse of 15 m-long section of segmental lining occurred 150 m behind one of the TBMs in mid-November without injury or loss of life. January 2000. Yorkshire Water has decided to recall its Lovat EPB Gloria to complete the final section of its stricken 10.6 km Humber wastewater tunnel at Hull in the north of England. Some 80% of the tunnelling had been successfully completed when a section of the 3.6 m i.d. segmentally-lined tunnel mysteriously collapsed some distance behind the face. Investigations are continuing into the cause of the incident, and there is presently no indication of anything other than a localised situation. The affected area has been stabilised using compressed air, and will be dug out and relined conventionally. A 22 m-deep retrieval shaft will be sunk 50 m ahead of the idle face, and TBM Gloria will drive towards it in an easterly direction from an existing launch shaft. Because the tunnelling was running three months ahead of schedule at the time of the incident, the original project deadline of November, 2000 is not affected. More at www.yorkshirewater.co.uk March 2000.Extensive ground investigation since the collapse has identified a layer of heavy peat at 40 m depth, some 18 m below the tunnel alignment, which may have caused the ground movement that resulted in failure of the non-bolted segmental concrete lining, trapping the TBM. The final 2km of the drive has since been completed by Miller Tunnelling using its second Lovat TBM. Work is proceeding to recover the trapped TBM. Visit www.millerconstruction.co.uk August 2000.

Railway

Amtrak has achieved a major milestone for the Frederick Douglass Tunnel Program with the selection of a Kiewit/J.F. Shea Joint Venture to build the brand new rail tunnel that will serve electrified Amtrak and MARC commuter trains. Located just south of Baltimore Penn Station, the new tunnel will serve electrified passenger trains with two parallel, single-track tunnel tubes, each approximately 3.22 km (2 miles) long. It will also support much faster travel speeds than the existing tunnel, where trains are currently limited to maximum speeds of 30 mph due to the tight curves.

The Frederick Douglass Tunnel will replace Amtrak’s existing Baltimore and Potomac (B&P) tunnel, which opened 150 years ago during the Ulysses S. Grant Administration

The third and final construction contract to “fit out” the Frederick Douglass Tunnel with tracks, rail systems and more will be announced at a future date, with an anticipated award in 2025/2026. Amtrak will also soon select a Delivery Partner to coordinate and support the successful execution of the Program.

Construction of the new tunnel is being delivered through the innovative Construction Manager At-Risk (CMAR) delivery method, which improves project delivery time and allows design, pre-construction and other work to proceed simultaneously.

Railway

The joint venture Skanska/Fay Construction Co signed a contract with CSX Transportation for the modernization of the Howard Street Tunnel (HST), originally constructed in 1895 and part of the HST Project in Baltimore, Maryland, USA. The Howard Street Tunnel Project will improve clearance at the Howard Street Tunnel (HST) in Baltimore City and 22 other locations where obstructions exist along the CSX Transportation (CSX) Interstate 95 (I-95) rail corridor between Baltimore and Philadelphia.

The modernization of the Howard Street tunnel consists of vertical clearance improvements to allow double-stack trains (trains transporting shipping containers stacked on top of each other) to travel between Baltimore, Maryland and Philadelphia, Pennsylvania. Work includes lowering and tunnel enlargement techniques across the 2.7-km (1.7-mile) expanse of the Howard Street Tunnel to increase the tunnel height from 5.8 to 6.4 m (19 to 21 feet). Additionally, drainage improvements will be made throughout the track. Visit

Sewage Interceptor

Granite Construction Company secured the USD215 million contract for the Northside Interceptor Tunnel project, whose design was completed in the Spring of 2023. The City of Akron (Ohio, USA) performed a pre-qualification process, with four contractors selected to submit proposals.

The Northside Interceptor Tunnel Project is one of the final projects of the EPA mandated Consent Decree, entered in 2014, to improve the City’s sewer infrastructure and reduce combined sewer overflows (CSOs). This project consists of constructing a 5.3 m (16.5-foot) internal diameter tunnel. The tunnel will collect and store CSOs from four overflow locations, which are located along the Cuyahoga River. The tunnel route follows Riverside Drive from Cascade Valley Metro Park – Chuckery Area to Front Street. It will be 2,030 m (6,660 feet) long, over 30 m (100 feet) below ground in rock, and will be able to store over 38 million liters (10 million gallons) of combined flow. The project is planned to begin in September 2023 and is expected to be completed in July 2027.Visit https://investor.graniteconstruction.com/ and https://www.akronwaterwaysrenewed.com/. 34/23.

Floodwater

Tarrant Regional Water District (TRWD) has selected the Traylor-Sundt Joint Venture (TSJV) to construct the IPL Section 19 Long Tunnel Crossings project (PL19TUN). The entire IPL Project is an integrated water delivery transmission system in the Dallas area consisting of 241 km (150 miles) of pipeline, three new lake pump stations, and three new booster pump stations delivering a required capacity of 1.32 bn liters/day (350 million gallons per day (MGD) of raw water to North Central Texas. TRWD and the City of Dallas Water Utilities currently serve over 4.1 million residents and the IPL will allow these agencies to continue supporting regional community and economic growth.

The Section 19 Long Tunnel project includes two EPB TBM tunnels totaling 3.34 km (10,944 linear feet); two micro-tunnelling runs totaling 526.39 m (1,727 linear feet); 27,74 m (91 linear feet) of hand-mined tunnel; and installation of 2.13 m (84-inch-diameter) carrier pipe throughout. Notice to proceed is anticipated next month, with expected completion in early 2026.
