DYWI® Drill Hollow Bar Anchors secure "Electra" Building in San Diego
Conversion of the former "Old SDGE Station B" in downtown San Diego, CA
The historic “Old SDGE Station B” building is located in downtown San Diego. The building was originally built in 1911 to accommodate the boilers and turbines of the San Diego Electrical Railway Company. Later it became the property of the San Diego Gas & Electric Company under whose name it is still known. A builder applied for the permit to build a new 43-storey high-rise building on that site. However, the historically deemed facade with its neo-classical and Art Deco stylistic elements was to be maintained. Therefore, it was decided to build the new high-rise building within the old facade and to integrate the facade into the new project.
For this purpose, the SDGE building was entirely gutted inside, and the facade was elaborately stabilized during the construction. In addition, the load capacity of the foundation soil had to be improved in a sustainable manner for the anticipated loads of the new skyscraper. Following its completion in December 2007, the new nostalgic complex will bear the name of "Electra" - in reference to the former owners of the site - and offer about 250 modern, luxurious apartments with a magnificent view of the harbour and the city of San Diego.
Condon-Johnson & Associates Inc., San Diego, was awarded the contract for the excavation, sheeting and shoring work. To increase the load capacity of the foundation soil DYWI® Drill Hollow Bar Anchors were used.
DYWI® Drill Hollow Bar Anchors can easily be installed on the construction site under confined space conditions using simple and small dimensioned drilling equipment.
The DYWI® Drill Hollow Bar Anchor System offers the following advantages:
- use of small dimensioned drilling equipment.
- No predrilling need under limited space conditions.
- Simultaneous drilling and grouting in a single operation.
For this landmark project that will exceed any other buildings in San Diego after its completion DSI Long Beach supplied a total of 10,000 ft. DYWI® Drill Hollow Bar Anchors type T76S including hardware accessories such as drill bits and couplers.
