Just south of the River Thames, the 10-acre former New Covent Garden Flower Market site is being redeveloped as a mixed-use development featuring 12 residential buildings and a Linear Park that will run from Vauxhall Bridge to the Battersea Power Station. The luxury residential towers will rise up to 55 floors above a deep, single level basement containing servicing and parking. Other facilities will include restaurants, bars, retail outlets, and commercial space.

Langan supported the ambitious design and construction program from the outset, assisting in the execution of a £1m geotechnical and geoenvironmental site investigation and a preliminary pile testing program. Working closely with the project architect, we completed complex Finite Element analyses to optimize pile group arrangements, seeking to facilitate rapid construction methods whilst ensuring associated settlements were within acceptable tolerances between adjacent buildings and the site-wide basement.

Discharge of pre-commencement planning conditions was a key constraint and we provided a range of technical submissions regarding drainage, contamination and piling. The site is also severed by a 1.75m diameter Victorian sewer, which the development wraps around. Langan assisted in approvals for construction activities around this sensitive Thames Water asset, working closely with various contractors to develop acceptable construction methods and sequences to protect the sewer.

Storm water attenuation, collecting water from across the extensive podium together with the foul water network was developed while working closely with the architect and engineering teams.

Subsurface Evaluation Geotechnical Engineering Foundation Recommendations

LOCATION: London, United Kingdom CLIENT: Confidential STRATEGIC PARTNERS: Severud Associates

Langan provided technical advisory services to the private developer for the renovation and expansion of this mixed-use development behind the Aldwych.

The subsurface stratigraphy was inferred to consist of approximately 15 feet of surficial fill overlying three to five feet of dense sandy gravel followed by a five to ten feet layer of brown clay and the blue London Clay, which is in excess of 85 feet thick.

The existing 11-story building consisted of three main cores with a two-level basement, and is supported on straight shaft and belled drilled piers founded in the London Clay. The proposed expansion included additions of six to eleven stories to the main cores, resulting in additional column loads of 350 to 400 tons. Design information for the foundation system or recent boring and test data were not available.

Langan reviewed project drawings for the existing building, as well as laboratory test results and published data on London Clay. A shear strength profile was developed for the London Clay and used to estimate the capacities of the existing straight shaft and belled piers. Recommendations regarding load capacities of existing foundations, design criteria for installation methods and cost for new drilled piers were developed.

Located on the pedestrian “Design Trail” along Union, Great Suffolk, and Holland Streets, this five-star hotel provides luxury accommodations for visitors visiting Shakespeare’s famous Globe Theatre and Tate Modern art gallery. The hotel features 292 rooms, restaurant, and 25 suites with views of the city skyline. A spa, ballroom, and meeting rooms are located within the site’s basement level.

As project director, Mr. Gildea was in charge of design and construction of the complex sub-structure elements. The threestory deep (28,000 m3) basement consists of health spa, meeting room and a ballroom large enough to accommodate 700 people. Basement construction/excavations were extremely complex due to very poor ground conditions, potential for ground movement, and a site bounded by roads on three sides and a party wall along the fourth. With a total volume of 28,000m3, this project was one of the largest basements under construction in the capital at the time. Supporting the walls of this excavation required propping capable of spanning more than 30m.

Bearing piles were also designed and constructed to be installed from low level using a combination of specialist low height rigs between props and standard CFA rigs. The key to securing this contract was the complete re-design of the reinforced concrete superstructure to ‘post-tensioned.’ This delivered considerable cost and program savings to the client.
