Materials for cast-in-place concrete shall be concrete meeting the requirements of §557, §501 and appropriate mix design requirements specified in Table 2 of Materials Procedure (MP) 501-2 Mix Design and Approval Procedure for Performance Engineered Mixtures – Structural Concrete. Mixes shall be modified to include corrosion inhibitor meeting the requirements of §711-13. The penetrating type protective sealer shall meet the requirements of §717-03. Reinforcement shall meet the requirements of §556.
562-3 Construction
562-3.01 Design. An appropriate structure design and all details necessary for construction meeting the
Design parameters given in these specifications shall be developed and submitted to the DCES for approval. All design work, detail development, and proposed handling and installation procedure development, shall be done by a Professional Engineer. The design submittal and the fabrication of the units shall conform to the requirements stated in the PCCM. The DCES reserves the right to reject a proposed design(s) if the structure type is determined to be unsuitable for the proposed application based on safety, durability, serviceability, or maintainability

I.The proposed structure shall provide hydraulic area (effective flow area) below the design high water elevation shown in the contract documents.
J.Allowable Concrete Stress shall be per the provisions of the NYSDOT LRFD Bridge Design Specifications, except that maximum tensile stress in concrete for handling and erection loads when analyzed according to the proposed handling and installation procedures, shall not exceed 0.15 (f ' ci)1/2 where f’ci is the concrete compressive strength in ksi at the time being considered.
K.All joints between Span Units shall be designed to be leak proof. The determination of the acceptability of the proposed joint system by the DCES shall be final.
L.Construction joints: Construction joints within Span Units will not be allowed.
M.The Load Rating package shall be prepared per EI 20-026 Load Rating/Posting Guidelines for State-Owned Highway Bridges.
N.Lap Splices shall be designed per NYSDOT LRFD Bridge Design Specifications and the NYSDOT Bridge Manual.
O.The structure shall be designed to develop adequate global and local capacities required to resist the loads in section 13 of the NYSDOT LRFD Bridge Design Specification.
562-3.03 Changes to Design Parameters. If the Contractor wants to propose a structure not in full
compliance with the design parameters in the contract, a preliminary proposal, fully explaining the changed design parameters shall be submitted to the DCES for review and approval. The Contractor is not expected to develop a detailed design until the proposed design parameters have been approved by the DCES.
562-3.04 Design Computations, Shop Drawings/Detail Drawings. The preparation and submission for
review and approval shall be according to the PCCM. Shop drawings shall show detailed handling procedure to be used during fabrication, storage, and transportation of the precast elements. All necessary supporting calculations shall be included in the design computation package.
562-3 05
NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) January 1, 2026 Volume 2 Fabrication of all steel components shall meet the requirements of the SCM. Shop drawings shall show the required tolerances for the geometry of all precast components, placement of reinforcement, location of all inserts, etc. Design shall consider the effects of these tolerances.
562-3.05 Fabrication. Fabrication of all precast elements shall be according to the PCCM.
562-3.06 Installation Drawings. Installation drawings shall meet the requirements of the PCCM and the
following:
A.Details of all joints including all materials and a step-by-step procedure for installing them shall be shown on the installation drawings.
B.All welding operations during installation shall be shown on the installation drawings and shall meet the requirements of the SCM.
C.Details for all cast-in-place concrete not detailed in the contract documents.
562-3.07 Installation. Installation of all precast elements shall be according to the approved installation
drawings. All elements after installation and prior to backfilling will be inspected for cracks or other visible defects. All defective elements shall either be replaced or be repaired using procedures approved by the Engineer and at no additional cost to the state. Cast-in-place elements shall have laitance removed by blasting and shall be coated with penetrating type protective sealer.
562-3.08 Erection Drawings. A separate set of erection drawings shall be prepared and submitted for
review and approval of the Department as per the provisions of Section 2.6 ERECTION DRAWINGS of the PCCM.
562-3.09 Backfilling
A.Backfilling operations shall not begin until:
1.Span units to span unit footing key joints are grouted as shown on the approved installation drawings and have cured a minimum of 24 hours.
2.Transverse connections between unit segments are placed and secured (if required).
3.Joint seals are properly placed and approved by the Engineer.
B.Backfilling operations shall be conducted in accordance with Section 203 - Excavation and Embankment, with the following modifications:
1.Fills shall be placed and compacted in layers not exceeding 12 inches in depth.
2.Dumping for filling operations shall not be nearer than 3 feet to a plane passing vertically through the back face of any footing.
3.Backfill shall be placed as symmetrically as possible around the structure with differential depths of backfill on opposite sides of the structure span units not exceeding 18 inches.

4.Fill within 1 foot of any surface of the structure shall be compacted with hand compaction equipment.
5.Vibratory rollers shall not be used within 10 feet of any surface of the structure.
6.Construction equipment shall not travel or rest on an uncompleted structure unless the designer of the structure span unit has evaluated the loading conditions, submitted calculations to the DCES, and has received written approval of the proposed loading. Actual conditions at the time of loading, including both the weight of the fill and the equipment, shall be part of the analysis. The Contractor shall repair any damage resulting from equipment passage at no additional cost to the State.
562-4 METHOD OF MEASUREMENT. Measurement for payment for the Reinforced Concrete Span
Units, Wing Walls, Apron, and Invert Slabs will be computed from the payment lines shown on the plans. No field measurements will be made. The quantity to be paid under this work for the Reinforced Concrete Span Units, Invert Slab with Cut-Off Wall and Concrete Apron with Cut-Off Wall shall be the number of square yards of plan area. The quantity to be paid under this work for the Wing Wall with Footing shall be the number of square yards of face area.
562-5 BASIS OF PAYMENT. The Contractor shall include the cost of all engineering, labor, materials,
and equipment necessary to complete the work in the unit price bid. The Contractor shall include the costs of the footings, headwalls, and cut-off walls in the unit price bid of the element to which it is attached. The Performance Concrete Quality Units will be calculated in accordance with §501-5, Determination of Quality Adjustment. Payment will be made under: Item No. Item Pay Unit 562.01nn Reinforced Concrete Span Units Square Yard 562.02 Invert Slab With Cut-Off Wall Square Yard 562.03 Wing Wall with Footing Square Yard 562.04 Concrete Apron With Cut-off Wall Square Yard 562.99 Performance Concrete Quality Adjustment Quality Unit NOTE: Serialization for the Span Units: nn represents the specific structure identifier.
