DDI was engaged in this project well after the commencement of construction. Unseasonal rains and the general low-lying elevation of this project significantly altered the site conditions and required an immediate response, which did not allow for a detailed scope of work or matting plan to be developed. However, once DDI was brought onto this project, our team was able to create a scope of work moving forward. Our new scope included supply, installation, and removal of timber access matting, support of line construction and foundation operations, and site cleanup/restoration of this 24.9-mile new transmission line build.
As matting was an unbudgeted expenditure, DDI was awarded this work based on proposing to mobilize only 3,500 mats to construct the entire project. DDI executed the project with this minimal amount of matting by constantly “flipping” mats to stay ahead of line construction and foundation crews. DDI’s “flipping” mats approach required detailed planning and coordination with other project coordinators as multiple operations were constantly in progress throughout this project.
Despite the numerous logistical challenges caused by this approach, DDI crews successfully managed their scope of work without any schedule delays to line or foundation contractors.
