Swift Lift System:
Used by Inland on most precast products, the Swift Lift System is a connect/disconnect system allowing precast concrete elements to be handled quickly, repeatedly and safely. Swift Lift pins are cast into our products at the time of manufacture. Installers will need to have the appropriate Swift Lifting Eyes (clutches) on site. Depending on the product, four ton or eight ton lifting eyes will be required. Swift Lifting Eyes are available for purchase from Inland. Please contact our sales office for pricing.
Rubber gaskets can be installed along with concrete pipe and manholes to create a watertight connection.

Proper installation of concrete pipe and boxes is crucial to ensuring pipelines perform to the designer’s requirements, both structural and otherwise. The American Concrete Pipe Association (ACPA) has conducted years of comprehensive analysis and
research on the performance of buried concrete pipe and boxes. The knowledge gained through these many years of experience is presented in the following guide. Please note that this manual is intended as a guide and does not supersede any specific
project specifications. To view ACPA's Concrete Pipe & Box Culvert Installation Guides, click here.
The Standard Installations (Type 1, Type 2, Type 3, and Type 4) are four standard beddings for concrete pipe that reflect the many factors affecting the pipe-soil system. A Type 1 Installation requires the highest level of compaction and the highest quality
granular material; a Type 4 Installation requires the lowest level of compaction and lowest quality bedding material.
The Standard Installations were developed through years of investigation and research into the behavior of concrete pipe in buried conditions. The Standard Installations provide both the designer and the installer with quantifiable, versatile, and conservative soil types and compaction levels for the material used in the installation. These installations facilitate the design of a rational and cost-effective concrete pipe soil system by providing an optimum range of installation characteristics.

Post Installation Inspection is an effective way to evaluate newly installed pipe systems. As Post Installation Inspection data is generated and presented to owners, engineers, contractors and inspection professionals, the need to properly and efficiently
evaluate the identified issues becomes critical. Decision-makers must be trained to differentiate between conditions that require remediation and conditions that are purely aesthetic.

Need help designing your buried infrastructure system? The free web-based PipePac software helps select the right material for the job. PipePac consists of three independent programs: Structural Calculations (3EB), Cost Analysis of Pipe Envelope (CAPE),
and Life Cycle Analysis (LCA).
- The 3EB program helps to analyze what structural capacity of pipe is required based on the specific site conditions. 3EB computes the earth and live load on the buried concrete pipe and relates the supporting strength to the strength obtained in a Three Edge Bearing test through bedding factors.
- The CAPE program helps estimate the cost of different installations for both flexible and rigid pipes.
- The LCA program promotes more cost-effective project designs by analyzing the true cost over the design life of the project.

The Concrete Pipe Design Manual is a must-have for anyone planning to design using concrete pipe. The Manual helps engineers specify and select the type, size and strength requirements of concrete pipe. The manual includes information on standard installations using the indirect design method, hydraulics of sewers and culverts, live loads and earth loads, supporting strengths, supplemental design data, and much more. Various tables, figures, and detailed example problems help to improve understanding of how to design with concrete pipe.
Many specifications, such as municipal specifications, explicitly state the minimum manhole diameter allowed based on the diameter of the incoming pipes. However, there are also physical and structural requirements that may require the manhole diameter
to be increased based on the quantity and orientation of the entering pipes.
Illustrations of standard maximum allowable pipe diameters for various manhole diameters are available for Alberta and Manitoba/Saskatchewan. If you are unsure what size of manhole would be required for your specific project, contact us.
