Ik was also decided by the ACI 318 Committee, that if the same bonded reinforcement were required for both bonded and unbonded post-tensioned two-way systems, the structural integrity requirements for both systems should also be the same, The structral integrity requirements. Six commenters suggested the move away from the term fracture critical (FC) is unnecessary and will cause confusion. It is the combination of the probability of an event and its consequence. Increased inspection frequency alone does not fully resolve a critical finding if the underlying safety issue is not rectified. nose ejection (c) For modifications to existing bridges that alter previously recorded inventory data and for newly constructed bridges, enter the inventory data into the State transportation department, Federal agency, or Tribal government inventory within 3 months after the month of opening to traffic.

One commenter requested that subpart D not be removed and that FHWA keep the sufficiency rating used in previous NBIS regulation as it provides a process for prioritizing bridge rehabilitation and replacement projects. 23 (HEC-23)Bridge Scour and Stream Instability Countermeasures: Experience, Selection, and Design Guidance, Third Edition. . Two commenters suggested adding internal and system redundancy to the definition for nonredundant member in accordance with the AASHTO guide specification. The Designated Lead State is determined through agreement between the two bordering States. stable observer officer length of bore . FHWA response: A regulation identification number (RIN) is assigned to each regulatory action listed in the Unified Agenda of Federal Regulations. Private bridge35 commenters requested the addition of a definition for private bridge. The justification for this range is described more fully under Section 3 of the RIA under Section 650.311: Inspection Interval. assignment There may be situations where it is not necessary for a Team Leader to lead the inspection, but this must be documented in the special inspection procedures. Curved bridges can require different procedures and specifications for structural analysis and design, and for load rating analysis for legal and permit vehicles, including permit vehicle size restrictions. reduction 3. 1979 .

With this change, the reduced underwater inspection interval criteria will only apply to those portions of the bridge evaluated during an underwater inspection. Battalion Commander FHWA shares this concern, and allows omission of only those items where a null value can be verified by another means; a code of N is required for all inapplicable condition rating items and for all items where applicability cannot be verified via other data items. FHWA Response: With the publication of the final rule, the SNBI will supersede the FHWA Recording and Coding Guide for the Structure Inventory and Appraisal of the Nation's Bridges (Coding Guide), 1995. tactical headquarters A patched area that is sound is in fair condition per the AASHTO MBEI; the guidance provided in the tables for evaluating the condition of concrete components is consistent with that determination. Ts Thakur. This in turn may impact risk-based inspection interval selection, inspection scope, and repair prioritization. . FHWA acknowledges that all factors requiring bridge closure cannot be anticipated; therefore, these procedures are expected to be general in nature and should be applicable to many bridges. FHWA recognizes that HECs 18, 20, and 23 are the state of practice for the appraisal, design, and inspection of bridge scour, stream stability, and scour countermeasures. adjustment for reference point shot seating . . .

Any new, rehabilitated, or structurally modified bridge must receive an initial inspection, be in service for 24 months, and receive its next routine inspection before being eligible for inspection intervals greater than 24 months. Commenters also requested that owners have discretion to set criteria for when a bridge needs to be re-rated and the priority for completing the load rating. super structure FHWA continues to work closely with Tribal governments on the implementation of the NBIS program through BIA coordination. field work that agencies use to create their documents. This manual is available at the following URL: FHWA encourages bridge owners to evaluate use of advanced technologies in bridge inspection. FHWA agrees that documenting equipment, while a good practice, does not need to be written in a plan or a procedure for all inspection types and has removed that statement from this section of the final rule. One commenter felt it was a positive addition. closing tolerances 3 Emergency Evacuation Designation Four commenters suggested adding the Item ID to the Expanded Table of Contents (TOC) as a cross reference to the item name, to make the TOC more useful and easy to use. automatic relief valve https://www.federalregister.gov FHWA agrees and deterioration mode has been added to the final regulation. : : . weapons tight plotting scale The NBIS provides minimum national standards and organizations can make their standards more stringent than the NBIS.

FHWA disagrees that fracture control plan needs to be defined in the regulation as it is a commonly recognized term, which was implemented by AASHTO in 1978, and is well defined. Many journal en engineering field like prestressed concrete. FHWA Response: fluctuating In accordance with E.O. Comments on this topic are addressed under that section. angle of sight As HEC 18 and 23 and other guidance documents explain, bridges with the greatest risk from scour-induced failure should have a scour POA that describes installation of physical or hydraulic countermeasures, or even replacement, and also include a monitoring program that allows time to implement these physical or hydraulic countermeasures.
