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. 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. 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.
Substructure. 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. 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-
Substructure. Payment against Substructure shall be made on pro rata basis on completion of stage i.e not less than 25% of the scope of Substructure of the structure subject to completion of atleast two Substructures up to abutment / pier cap level of the structure.
Substructure. Agreement Administrator shall, at no cost to Operator, maintain the Substructure in a good and safe condition. If Agreement Administrator or the Operator determine that the decking over the East River constituting a part of JRB is unsafe, based on a report by an Agreement Administrator approved professional and certified consultant, because of spalling of concrete pilings, corrosion of metal pilings, or any other cause, then Agreement Administrator or Operator, as the case may be, may notify the other party of such determination, and thereupon, Operator shall cease using the decking. If any portion of the JRB must be shut down because of repairs or replacements, Agreement Administrator shall perform all necessary repairs on the Substructure, and this Agreement shall be suspended pursuant to Section 2.01(c) above until JRB resumes its normal operations.
