B&K Construction Co., LLC owns jacking and boring equipment to install steel casing pipe up to 96” diameter. The largest jack and bore project that the company has accomplished involved the installation of a 120″‘ diameter pipe 160’ long. The native material is inconsistent and a jacking and boring tunnel is generally hard to keep on line and grade. B&K crews excel at this task. With 25 years of experience in jacking and boring installations, the large diameter bores are installed on line and grade within 3/4 of an inch. The company’s experience is evidenced through the projects described on this page.
