SHEET & H-PILE

STEVENS’ work in Sheet and H-Pile self-performs in conjunction with our excavation and civil concrete work. Whether driven by schedule, safety, accessibility or efficiency, STEVENS, working with our own engineers at CDMG or an owner’s engineer of record, can help properly identify soil type and analyze geotechnical reports to properly layout and drive these types of pile as needed.

STEVENS Engineers & Constructors received the contract to install the H-Piling for the foundation support for the newly designed Dresden Energy Facility from Williams Service Group. The Dresden Energy Facility, a combined cycle power plant, is owned and operated by Dominion Energy. This site was previously rough graded when STEVENS began to work at the facility. Included in the scope of the contract was the final excavation required for each of the major foundation footprints.

Facts: Excavation – 19,000 cy
H- Pile installation – 1712 pile; 85,300 LF total; 200 splices

Description:

STEVENS performed the excavation work during late fall and through the winter under severe weather conditions. This enabled work to begin in early spring on the foundations, followed by the summer erection of the equipment. STEVENS met the proposed 7-week schedule through the utilization of 3 pile driving rigs and an aggressive 6-day work week schedule.

STEVENS had an impressive performance and safety record on the piling installation and was subsequently awarded the foundation contract for the Dresden Energy Facility foundations. STEVENS always strives for quality workmanship and a safety-first environment, making them a leader in the industry.

BETHLEHEM STEEL

Location: Sparrows Point, Maryland

STEVENS has performed piling on both large and small projects. These projects, ranging from sheet piling, used for a simple earth barrier or shoring, to miles of H-piling, used for structural foundation support, have all been successfully executed by STEVENS.

STEVENS was subcontracted by Fluor to execute the largest H-pile project, Cold Mill at Sparrows Point in Baltimore, Maryland. This project safely drove over 290,400 linear feet or 55 miles of 12 x 55 H-pile, using four pile driving rigs and four splicing crews. Approximately 5,280 sticks of H-piling were spliced at 2,640 individual locations with an average pile length of 110 feet. STEVENS was able to accomplish the piling in less than five months. At that time, this was the largest piling project on the east coast.

STEVENS completed other challenging projects at ATI’s Electric Arc and Reheat Furnaces. While driving sheet piling at ATI’s Electric Arc Furnace, STEVENS was dealing with limited head room. Poor soils were a concern while placing sheet piling at the Reheat Furnace. Public roadways and local authorities were additional obstacles that were present. Driving forty-foot sheet piles with only sixty feet of headroom and limited turning radius against the public right-of-way were obstacles that STEVENS’ project team was able to overcome by drawing from their years of experience to safely and efficiently complete the project.

ATI BRACKENRIDGE

Location: Brackenridge, Pennsylvania

STEVENS Engineers & Constructors were under two large contracts to install civil foundations at the ATI Brackenridge location when they were granted a third contract to conduct much of the site excavation. This site was particularly tight due to a new HSM that was being built in an existing facility surrounded by the town of Brackenridge.

STEVENS excavated down approximately three feet below the sidewalk, then drove 700 feet of SKM – 22 sheet piles along the road and 400 feet along the existing buildings. This was completed using two 80-ton with 100 feet boom conventional rigs. As the piling was going on, we moved a total of 70,000 cy of dirt, installed 30,000 square feet of sheet pile, put in the storm water pipe and demoed 10,000 cy of concrete all within five weeks. Working first shift only, along with the piling rigs, we had two 50-ton excavators, one 38-ton excavator with a hydraulic crusher, a 50-ton excavator with hydraulic hammer, a 38-ton excavator, a rubber tire hole, two D-6 dozers, two 30-ton art dump trucks, one road sweeper and 15-18 dump trucks on site.

This job was extremely tight and congested. STEVENS’ ability to self-perform at this type of work, under these conditions, especially considering the sheet pile, promotes the full benefits of safety and efficiency that we constantly realize within our projects.
