The INGAA Foundation has developed recommended guidelines that address winter season construction techniques under frozen conditions. The intent of these recommended guidelines is not to dictate one set of construction techniques for every project, but to provide an array of acceptable and proven techniques from which each Company can develop its own project-specific frozen conditions plan. The guidelines presented in this paper draw from the experience and leading best practices of the INGAA Foundation membership, interviews with industry practitioners (e.g., contractors, environmental inspectors, regulators), and reviews of construction plans for projects built under frozen conditions.
