Several untried environmentally sensitive erosion and sediment control methods were investigated and implemented into a large scale test site. Bioengineering and biotechnical mitigation designs were sought from specialists and incorporated into an unconventionally structured contract, which included the physical works as well as involving participants in field training and implementation of much of the work. The project success was a testament to the cooperation of the designers, the contractor and the owner. Bioengineering and biotechnical projects involve concepts that are difficult to 'engineer' and require significant flexibility in the structure of the contract and willingness of all parties to adapt to changing field conditions in order to field fit the designs With increased use of these methods, it is expected that more consultants will become comfortable with designs they cannot 'guarantee,' and contractors will develop skills to implement the designs, accepting the inherent risk of failure and the likelihood that changes will have to be accommodated during construction.
