FOR

WATER LEAKAGE ABATEMENT IN THE BASEMENT OF THE US EMBASSY, LONDON

United States Embassy at

33 Nine Elms Lane

SW11 7US

London-UK

US EMBASSY, LONDON – FACILITY MANAGEMENT

September 2023 – Rev 3

1. PURPOSE/ PROJECT INFORMATION

The US Embassy, London proposes to employ a specialist Contractor to repair the water ingress into the plant rooms and parking garage at the below grade basement floor of US Embassy, London. The work shall start in the Generators room, Pond Equipment room and Boilers room. If the repair work, that the Contractor has carried out in the aforementioned areas, is satisfactory, the work may be continued in the other areas of the basement as directed by the CO/COR.

The newly constructed U.S. Embassy, London has exhibited water ingress and seepage at various locations of the below ground construction of the building; there is evidence of water ingress to the diaphragm wall and mat slab since construction.

Water leakage into the basement has occurred since construction, primarily at the interface between the diaphragm wall and mat slab, pond wall and basement slab, as well as cracks in the mat slab.

The scope of work is defined by the Statement of Work and drawings. The work on the repair project generally includes the following:

a) Chemical grout injection at the following locations:

• The interface between the diaphragm wall and mat slab.

• The interface between the pond wall and basement floor.

• Cracks and construction joints in the mat slab and basement floor.

• Isolated cracks in the diaphragm wall and other locations with leaks.

b) Cutting and grinding to create water collection channels where conflicts or access constraints preclude grout injection. Forming collection chancels above slab is an option if the slab cutting is not possible.

The Contractor’s proposal shall include, but not be limited to, the following:

• All fees for transport and travel to and from site.

• All office based and site visit costs.

• Time for reviewing all historical information, drawings and data relating to water ingress.

• Any associated costs to conduct and complete the report works.

Upon project award, and subject to sensitivity, additional information may be provided to the Contractor for review, assistance, and understanding of the existing structure. This information will likely include:

• Pertinent drawings of below construction portion of the building

• Investigation of leakage in the basement/parking garage.

If any of the above-mentioned documents are Sensitive but Unclassified (SBU), then the

Contractor may only be able to review the SBU documents in the US Embassy office.
