Field Wide Pig Trap Safety Upgrade Program

Tegre completed walk downs for a client consisting of over 150 existing pig traps – focusing on safety concerns. Tegre designers and engineers created 3D models of the existing traps and redesigned with a focus on safety upgrades. Detailed drawings and Bill of Materials of the upgrades were produced.

Utility Exposure Rehabilitation

A client identified a high-risk pipeline exposure within a primary channel. Non-native species growth within the channel altered low-flow dynamics within the active floodplain, forcing unusually high flows and causing long-term and on-going risk to the pipelines.  Tegre staff designed a bank reinforcement at the site of the pipe exposure, re-establishing a stable bank, and developing a channel augmentation designed to promote near pre-existing low-flow channel dynamics for long term protection.  Tegre staff joined archaeological consultants to prepare necessary environmental products to satisfy tribal regulation and to obtain United States Army Corps of Engineers project authorization under §404 of the CWA and obtain water quality certification through the Environmental Protection Agency under §401 of that Act. Tegre staff also provided on-site Environmental Inspection services during project execution to ensure compliance with all involved agency mitigations.
