Dam Safety Engineering

Since being founded in 1972, Keller & Kirkpatrick has provided civil engineering expertise to both the public and private sector clients on a continual basis. We measure success by the fact that many of our clients are repeat clients. We realize that there is far more to dam safety engineering than simple technical prowess. It involves creative, cost-effective solutions, continual communication with our clients, a thorough knowledge of the entire approval process, and a total commitment to deadlines. Below is a summary of our qualifications:

The Experience

Over the past three (3) years, Keller & Kirkpatrick has been actively involved with many dam safety projects. These projects generally come to us as a simple annual “regular” inspection, but virtually every dam built prior to 1980 is by definition “hydraulically deficient” by today’s NJDEP Dam Safety Standards and as a result, NJDEP issues “Compliance” letters. We are currently working actively on performing the surveys and engineering analyses to bring nine (9) dams into full “Compliance”. This process is usually spread over several years due to lack of funding at the local and state levels.

The Skills

Keller & Kirkpatrick has in-house expertise in the following areas of practice which are all integral to addressing Dam Safety Compliance issues for our clients:

  • Topographic Mapping and Boundary Surveying including use of GIS
  • Hydrology and Hydraulic modeling of the dam and the upstream watershed using the HEC1 computer application for reservoir routing and dam breach analysis
  • Hydraulic modeling of the downstream watershed and affected structures using HEC2 and HEC RAS computer models to establish inundation areas using step backwater analyses
  • Structural Engineering
  • Preparation of Construction Plans and Specifications
  • Dam Safety Permitting
  • Wetlands Delineation and Permitting
  • Construction Surveying Services
  • Construction Observation Services and Certifications
