August 2016 – Precast of Maine had the honor of working in conjunction with T-Buck Construction, MDOT, A. L. Patterson, A. H. Harris, Auburn Concrete, Keely Crane and Casco Bay Transportation for the design, build, lift and delivery of four custom Precast Concrete Abutments for the Crockett Bridge replacement located on Rte. #117 in Naples, ME.
The finished abutments are a testament of teamwork and excellent communication between several involved parties working together to overcome multiple challenges. Before the project could begin, the Project Manager, Plant Manager and QC Manger put in many hours in discussion and meetings, examining numerous drawings and testing concrete mixes to ensure that all aspects of the build and delivery would meet strict standards and provide long-lasting quality for the years to come.
With each abutment weighing roughly 42 Tons (approx. 86,000 Lbs each), the sheer size and weight of each piece created daily challenges for our team including installation of the forms, insuring proper design and placement of reinforcement, confirming adequate supply of concrete mix and finding the right balance between technique and tools used to fill the forms. This project required construction of an outdoor production area to stage the forms, as each abutment was too tall, long and heavy to produce within our workshops. Once the concrete was poured, each abutment required 24 hours to harden before the form pieces could be stripped and used to make the next abutment. After all the abutments were stripped from the forms, it was time to focus on preparing for delivery.
Have you ever thought about the logistics behind what it requires to lift 42 Tons of precast concrete and deliver it over 40 miles away? Now, throw in the factors of keeping the product damage free, while doing your best to ensure employee safety throughout the task. Not a process to be taken lightly. An essential part of the project and a key challenge were determining and renting the accurate type of crane and lifting equipment for the weight, along with the correct size low-boy trucks to deliver the tall and heavy product safely. This was an impressive undergoing that relied on solid communication and teamwork between our crew, Keely Crane and Casco Bay Transportation.
