MJW Completes Rail Unloading Project for Continental Building Products // November 2018

MJW Consolidated has completed a rail car unloading project for Continental Building Products at Palatka, Fla, that is helping the gypsum wallboard manufacturer meet its demand for raw materials.

Completed in July, the project involved the construction of an unloading and conveyor system that removes gypsum from incoming railcars and transfers the material to storage piles. MJW self-performed the excavation, construction and equipment installation for the project.

One of the main features of the project is a concrete-lined, 18-foot-deep receiving pit and 16-by-26-foot concrete ramp. To create the pit, MJW excavated 1,000 cubic yards of soil and poured 560 cubic yards of concrete, including 40 sonotube foundations.Continental BP 1

 The unloading process involves a rail car rolling into position above the pit, where it is grabbed by a hoist and shaken to fully discharge the material from an opening at the bottom of the car. Inside the pit, two Cogar feeders move the gypsum to a conveyor system that carries it to a radial stacker in the storage yard. MJW crews installed 1,260 feet of conveyors with cover supports and two transfer towers. The project required 30,000 pounds of structural steel.

The entire project was completed while the plant was in operation. MJW crews worked six- to seven-day weeks throughout most of the project. “Keeping the pit dry during the summer months was one of our biggest challenges,” said Justin Freeman, project manager. “But we had an experienced team on the job with an exceptional group of supervisors who kept us on track throughout an aggressive project schedule.”

MJW Designs Innovative Fire Protection Solution for Albany International // October 2018

An innovative MJW Consolidated solution to a potentially serious problem is helping an Albany International Corp. facility in St. Stephen, S.C., strengthen its fire suppression system.

The solution involves installing a new fire pump and reconfiguring the plant’s fire water supply to assure the system’s ability to deliver sufficient water volume and pressure to a fire.

 Planning for the project began after MJW installed a new low expansion foam system at the plant and discovered that the existing fire pump, located in a pit next to a concrete water retention pond, was in poor condition and incapable of maintaining the required pressure.

MJW project manager James Marks proposed relocating a new pump to the top of the existing pit, then converting the pit into a sump fed from the retention pond. In addition to boosting water pressure, the solution would help prolong the life of the new equipment.

Scheduled for completion in December 2018, the project calls for demolition and removal of all existing equipment inside the pit, then sealing the pit and cutting a hole in the retention pond wall to allow water to fill the new sump. A new valve house and vertical turbine diesel fire pump will be installed at the top of the pit. Water will be drawn from the newly converted sump and tie into the existing underground  fire loop.

In addition to designing the solution and installing all system components, MJW will perform concrete work and equipment placement.
