The ACPA makes software available to the industry to help design projects and select the right materials. The PipePac Software is developed in cooperation with other partners while Eriksson Pipe and Eriksson Culvert is developed by Eriksson Software. Working closely with Eriksson developers and a team of ACPA members and staff, the ACPA supports and recommend use of the Eriksson Software packages.
Eriksson Pipe is a computer program that performs the structural analysis and design of circular and horizontal elliptical reinforced concrete pipe. Internal dimensions of pipe culverts are sized based on hydraulic or other service requirements and are then structurally designed to support the weight of earth, live, or other loads that are imposed on them. Eriksson Pipe provides the structural analysis and reinforcing design. This method of design allows the user to obtain reinforcing steel areas for user-specified pipe geometry, material properties; and loading data.
Eriksson Culvert is the most advanced engineering software for precast and cast-in-place box culverts, seamlessly combining the functionality of a state-of-the-art structural analysis engine with fully automatic design and analysis capabilities. Integration of the critical design tasks into one system means you get superior productivity and flexibility with improved quality control.
All median drainage should be submitted to INDOT Hydraulics for review. The IDM is limited in guidance for median drainage design and submittals. The following should be used in conjunction with the IDM to produce an optimal median drainage design for INDOT purposes.
An infiltration facility collects and retains runoff for the purposes of infiltrating into the soil to outlet into groundwater. Runoff is designed to be removed by means of infiltration through a permeable bottom. Infiltration is not preferred as a method of stormwater management and should only be considered at locations where site conditions limit other means of stormwater management and allow for infiltration. The Office of Hydraulics should be consulted to ensure that infiltration is the appropriate means of stormwater management for a select project area.
Soil characteristics are the primary concern in designing an infiltration pond. Infiltration facilities can be subject to failure due to plugging with fine material and debris running off of the site and require routine maintenance.
Inlet configurations for the pipe end sections: grated box types I and II, metal end sections, precast concrete, and safety metal culvert end sections for smooth pipes is recommended to have a the inlet configurations similar to that of a headwall.
A 3 sided structure, whether it is a flat top, arch top, or slab top, should have its low structure elevation, flow line elevation, and sump labeled in the hydraulics memo with their respective line in the table. The span should be labeled within the type of structure line. To avoid confusion, the rise of the structure should not be stated as the flow line elevation, sump depth, and low structure elevation will be the necessary information for the structural and environmental engineer to use in the designs.
The proper way to submit projects with multiple types is to separate the types by category in a limited fashion. For example culverts will be their own submittal as well as detention in its own and storm sewers in its own. Culvert submittals should be limited to ten structures.
Three-sided structures, spill through structures, storm drain systems, and structures with inlet depressions should not be sumped. For other culverts, sumping is required unless the Waters Report determined the location not to be a Waters of the US nor Waters of the State.
A culvert is a structure that allows water to flow under a road, railroad, trail, or similar obstruction. Typically embedded so as to be surrounded by soil, a culvert may be made from a pipe, reinforced concrete or other material. A structure that carries water above land is known as an aqueduct.
The analysis and design of a concrete box culvert can be further refined by considering other factors, such as the presence of groundwater, the effect of soil stratification, and the effect of soil consolidation. The analysis can also be performed using computer software or spreadsheet programs, which can provide more accurate and efficient results.
Overall, the analysis and design of a concrete box culvert provides a systematic and reliable approach to design and construct drainage structures that can safely and effectively convey water and other materials.
In auto design mode, Eriksson Culvert quickly analyzes and designs wall thicknesses and reinforcement sizes and spacing. A comprehensive reinforcement schedule containing rebar and mesh is produced, complete with all bar dimensions and bends. LRFD, Standard, AREMA, and CHBDC specifications are supported, as well as, both US customary and metric units.
The highly graphical user interface provides multiple views to render the design and present the results. Complete details of the design along with detailed calculations are provided. Powerful graphics show all rebar rendered in true 3D and a user-customizable truck library is included in the sophisticated live load capabilities.
With Eriksson Culvert, you can automatically design five different culvert types: four-sided, three-sided, multi-cell, type I, or type II. When a new job is started, the input boxes will each be initialized to reasonable default values in the following groups:
In Design Mode, Eriksson Culvert will determine the appropriate culvert properties such as reinforcement, slab thickness, and wall thickness. In Analysis mode, the user selects the slab and wall thicknesses, and sets most of the rebar sizes and spacing.
ABC design documents and supporting drawings have been incorporated into the Structures Design and Detailing Manual (SDDM) which consists of the Written Manual, Drawings, and Checklists. The SDDM references ABC decision making tools which are provided below.
For your convenience, hyperlinks are provided inside the drop down menu connecting to the locations where the referenced resources can be found.
Digital Delivery with Model Based Design and Construction (MBDC) is the use and transfer of digital data in design, construction, and asset management. Digital Delivery with MBDC is not solely intended to eliminate plan sheets but rather deliver data in more directly consumable formats for project stakeholders.
Culvert supports standard pipes and box culverts, calculating excavation, backfill, end structures and reinforcing steel, supporting Department of Transport and Main Roads Standard Drawings Roads: 1243, 1250, 1260, 1270, 1271, 1304, 1305 and 1359.
