Design Information
The Alberta Chapter and its member companies provides free specification review services. The Chapter and its members work with engineering staff to provide specifications that have been published by the City of Edmonton and the City of Calgary. The chapter will produce a letter including supporting documentation for engineers and technicians for specification updates. Following are design tools and information for buried pipelines and culverts.
A)Pipepac
Pipepac is the software suite that includes 3EB (Three Edge Bearing) indirect design software, CAPE (Cost Analysis of the Pipe Envelope), LCA (Lifecycle Analysis).
This software is free to download.

B)ACPA Software
The American Concrete Pipe Association's website providng software such as BOXCAR (Box Culvert Analysis and Reinforcing Design); PIPECAR (Pipe Culvert Analysis and Reinforcing Design); DASH (Detention and Sewer Hydraulics)

D)The History of Manning's 'n' Value
Read this document which explains why all buried pipe should be designed with a Manning's 'n' value of 0.013.

E)Lifecycle Costing Analysis
Life cycle costing includes all costs during a set service life. Take a look at the ASTM method for LCA.

F)Live Load Design
Live Loading is a crucial component of buried pipe design, especially with shallow installations.

H)Culvert Durability
The Ohio Department of Transportation (ODOT) has published a 173-page report on corrosion and abrasion resistance of various types of pipe and pipe protection used for culverts in the State of Ohio. This article reviews the Ohio report and presents a procedure for evaluating service life and life cycle cost analysis to enable consideration of pipe durability as a design criterion.
