Retaining Wall Design. The Consultant shall provide all necessary design effort required to produce a complete set of construction documents for a conventional retaining wall system. The Consultant shall also determine appropriate Proprietary Wall types from the FDOT FDM proprietary wall standards to the extent necessary to finalize the wall plans as described herein for proprietary wall systems. Retaining walls are anticipated at the following locations: At the County’s option, the Consultant shall obtain project specific retaining wall drawings from proprietary wall companies and incorporate these drawings into the contract document. [Add locations here]
Retaining Wall Design. 1.11.1. The Engineer shall determine if walls are required and verify the need for and length of the retaining walls.
1.11.2. The Engineer shall prepare a Retaining Wall Type and Cost report that documents the analyses comparing costs for each wall type and submit the report to the GEC. The Mobility Authority will approve this analysis prior to preparation of the retaining wall layouts.
Retaining Wall Design. The Engineer shall provide layouts (scale Max:1”=40’ and Min: 1”=100’), elevations, quantity estimates, summary of quantities, typical cross sections, and structural details of all retaining walls within the project.
Retaining Wall Design. The purpose of this task is to prepare retaining wall plans and details. GCE shall design retaining wall structures along FBPTR eastbound and westbound mainlanes. The design shall include MSE walls along bridge approaches as well as abutment walls. It is estimated that approximately 5,120 feet of retaining walls shall be required. The retaining wall plans shall include: Retaining Wall Plan (1” = 100’ scale in 11”x17” sheets);
a. Designation of reference line.
b. Beginning and ending retaining wall stations.
c. Offset from reference line.
d. Horizontal curve data.
e. Total length of wall.
f. Indicate face of wall.
g. Wall dimensions and alignment relations (alignment data as necessary).
h. Soil bore hole locations.
i. Inlet locations.
j. Underdrains and outlets to storm sewer. Elevation (1” = 10’ scale in 11”x17” sheets);
a. Top of wall/coping elevations every 25 feet.
b. Existing and finished ground line elevations.
c. Limits of measurement for payment.
d. Type, limits, of guard rail and/or coping (as applicable).
e. Underdrain placement and outfalls.
f. Required foundation improvements (as applicable).
Retaining Wall Design. As a part of the Xxxx Xxxxxx team, AECOM will provide retaining wall design and construction document production services in support of the Phase 1 construction of the M-line bypass pipeline and the drainage channel relocation. The design of the walls, for both Phase 1 features, will require close coordination with the overall design team. Wall type, design height and surcharge requirements will be determined based on plan, profile and typical section(s) of each feature developed by others. The limits of the walls and the wall types will be shown on the plan and elevation sheets developed by AECOM.
Retaining Wall Design a. In addition to drilling and lab testing, we propose to design a single gravity or reinforced modular block retaining wall at the site. From the information above and the information that has been provided, Xxxxxx will perform the following services:
b. Design of the retaining wall/s in accordance with NCMA design guidelines.
c. Global Stability Analysis on the critical wall section
d. Preparation of design calculations
e. Preparation of construction documents, plans and design notes
Retaining Wall Design a) The Professional shall prepare contract plans, special provisions for the specifications, and opinion of probable cost for the construction of permanent and temporary retaining walls required for grade separation and intersection improvements at 126th Street, 131st Street, 141st Street, and 000xx Xxxxxx. The contract plans shall include Typical Retaining Wall Sections, Soil Borings Sheets, Retaining Wall Detail Sheets including retaining wall quantities, and Construction Details Sheets as necessary. The contract documents shall contain sufficient information to enable the contractor to perform the work tasks described below.
(1) Permanent Retaining Walls Construct retaining walls using appropriate construction methods. These retaining walls are expected outside pavement edges along SR 37 to retain existing grades adjacent to the depressed roadway sections and along outside pavement edges of ramp lanes to contain construction limits within the existing right-of-way. Retaining walls may also be required in conjunction with bridge construction to provide for reduced span lengths.
(2) Temporary Retaining Walls Install temporary retaining walls using appropriate cut wall (top-down construction) methods. These retaining walls are expected along the centerline of SR 37 in the first phases of traffic maintenance to generate the depressed section for one half of SR 37 while the other half is maintained at existing grades. These walls would then be removed in the later phases of traffic maintenance after the entire section of SR 37 is depressed.
Retaining Wall Design a. The Developer shall submit final retaining wall drawings to the Town Engineer for review and approval prior to construction. The wall drawings shall be prepared by a Colorado registered Professional Engineer. A global stability analysis, with sections cut through the series of tiered walls, must also be prepared to demonstrate the stability of the wall system and the hillside.
b. The retaining wall system shall be constructed of Redi-Rock segmental block units utilizing the “LEDGESTONE” texture. The Developer shall submit a color sample of the proposed block material to the Town Engineer for approval prior to construction. The color shall be an earth tone in the beige/xxxxx color spectrum.
Retaining Wall Design. This task includes design at the 60%, 90% and final submittals and includes the following: ▪ Identify the required height and location of retaining walls from the roadway plan and profiles ▪ Prepare plan and profile sheets and detail sheets for each wall ▪ Up to four (4) minor walls less than four (4) feet in height will be required. ▪ Minor wall types are proprietary wall systems at four (4) feet or less in height and soil reinforcing is not required. ▪ Design calculations are not required for minor walls. ▪ Global stability issues do not exist at these locations ▪ Specific borings at minor wall locations are not included in this scope.
