Geotechnical Engineering
Since 1969, Coleman Engineering Company's Geotechnical Services
Department has completed subsurface explorations, laboratory testing and
engineering reports for projects that have included state and
federal governments, commercial, residential, industrial and institutional clients for
buildings, roads, bridges, treatment plants, paper mills, airports, mines, power
plants, wood product facilities, landfills and other solid waste disposal sites,
breakwaters, hydro electric dams, navigation locks and a variety of other civil
works projects.
Coleman Engineering Company projects are kept on schedule and budget by
implementing the following procedures:
- Proposing a realistic project specific budget and schedule.
- Preparing a project work plan with a detailed project task breakdown.
- Auditing costs at the completion of key tasks (flags) for the project,
such as the end of drilling and/or the end of laboratory testing.
- Providing detailed written instructions for each crew/team assigned a
key task, such as drilling.
- Assigning an experienced project manager to each project.
- Identifying the need for changes in the project scope of work and
promptly advising our client of these changes prior to implementation.
- Frequent coordination and communication with our client during project
task activities, including submittal of daily, weekly and/or monthly summary
reports.
