Substructure. All of that part of a bridge structure below the bridge seats, including the parapets, backwalls, and wingwalls of abutments.
Substructure. The part of the Structure below:
Substructure. The part of a structure that is below the bearings of simple and continuous spans, skewbacks of arches, and tops of footings of rigid frames, together with the back walls, wingwalls, and wing protection railings. Successful Offeror. The Offeror that will be recommended for Award of the Contract in accordance with the RFP. Superstructure. The portion of a structure that is not defined as Substructure.
Substructure. The four pylons rest on large concrete substructure foun- dations, 90 m (300’) in diameter and 65 m (210’) high, which distribute all forces to the soil. These include the horizontal forces that result from the inertia of the structure in relation to the action of the hydrodynamic forces generated by motion in the ground during an earthquake, as well as the overturn- ing moment generated by the horizontal forces and their level arm. Below this substructure, designers improved the bearing capacity of the soil by adding inclusions, which consist of 20 mm-thick (.79”) steel pipes, approximately 25 to 30 m (82 to 98’) long and 2 m (6.6’) in diameter, driven into the soil at 7 to 8 m (23 to 26’) intervals. The gravel layer acts as a fuse, limit- Xxxxx Xxxxxxxxxx Above: The team pushed the central span length as far as it conceiv- ably could—to go further than 560 m (1,837’) would require a steel box girder design for aerodynamic stability.
Substructure. Mini-Piers – Essentially to remain with only minor patching of spalled or damaged areas. • Center Pier – Remove and replace the existing stone masonry section which has failed and fallen into the river. The existing concrete portion of the existing pier is to remain and the proposed section will generally match that of the existing concrete section in shape and foundation depth. Place new bridge seat as needed on the existing concrete section. • Scour countermeasures – To be evaluated to determine expected scour and resulting countermeasures required. Scour countermeasures will be designed and proposed based upon potential wetland/river impacts and feedback from the City. • West Abutment - Remove and replace the failed existing stone masonry section in the middle of the abutment with a reinforced concrete stem section, utilizing the existing abutment foundation and footing. The remaining stone masonry sections to either side of the failed section is to be repaired and re-pointed, and a new bridge seat installed as needed. • East Abutment – Repair and repoint extsing stone masony. Install a new bridge seat as needed.
Substructure. 2.2 Superstructure
Substructure. The basement area is a reinforced concrete box, formed by a secant piled wall to three sides, and a reinforced concrete retaining wall to the south elevation. The basement walls are designed as being propped by the concrete basement and ground floor slabs in their final condition Moisture Resistance • Car Park—Grade 1 • Storage Areas—Grade 3
Substructure. Pier and or abutment dimensions must accommodate future track(s) and Access Road per Section 4.1.3 and 4.1.4. Footings for all substructures shall be located and designed to allow a minimum of 12 feet measured perpendicular from centerline of nearest active track to face of shoring to facilitate footing construction. Temporary shoring shall be designed per Section 4.4.2. Cross-hole Sonic Log (CSL) Testing may be required by the Railroad to evaluate the integrity of drilled shafts/caissons. The Plans and Specifications shall include provisions for this testing. Drilled shafts within the influence of track surcharge shall be designed with temporary casing for protection against cave-in, subsidence and or displacement of surrounding ground. Casing shall be designed for live load due to the Railroad surcharge in addition to all other applicable loads. Drilled shafts shall be designed to allow the drilling operation to proceed without impacting the Railroad operation.
