MOST: Mobilization, Optimization, Safety, and Training
MOST was established in 1989 as a joint labor trust fund by the International Brotherhood of Boilermakers (IBB) and the National Association of Construction Boilermaker Employees (NACBE). The purposes of MOST are to maintain a highly skilled workforce, to maintain current skills and develop new skills and technology, to instruct and teach safe work habits, not only for Boilermakers, but for all who are involved on a project, and to help provide a drug free work place. MOST is a national Boilermaker program being used everywhere in the United States by the Boilermakers. The MOST program is divided into six categories: Safety Training, Drug Screening, Reserve Center (for project manning), Prescription Safety Glasses, Medical Screening, and Common Arc (for certification of welders).

OPEN CELL® Bulkheads for Cofferdams and Docks
OPEN CELL®
Bulkheads is a modification of the typical
closed-cell cofferdam shape. The system is a modern combination of two
old ideas; reinforced earth and cellular sheet pile construction. It is
a cellular flat sheet pile structure in which each cell's sheet piles
are driven in the shape of a U when seen from above. The sea side of
each cell is typically circular, while the tail walls forming the
uprights of the U shape are unconnected. These tail walls act as
soil/friction anchors for the curved sheet pile cell faces. By not
connecting tail walls at the landward side, several savings are
immediately realized, including less sheet pile area, greater
construction tolerance and adjustment capability, minimal pile
penetration, and much easier backfilling. In seismic regions, the tail
walls can be extended as required to guarantee fill mass stability. OPEN
CELL® Bulkheads relies solely on the vertical soil/friction flat
sheet pile anchor wall to restrain a curved flat sheet pile arch face.
Embedment of the face sheet piles is not a factor in wall strength
either in overturning or shear. In effect, the bulkhead becomes a series
of U-shaped horizontal membrane structures that need no toe embedment
for stability.

Strain Memory Alloy Passive Sensors for Civil Structures
IntelliSenseTM devices are a line of strain memory alloy-based passive
sensors for use in civil structures and other applications. At their core
are metal alloys that remember strain. Strain can range from as little as 20 micro-strains (or .002% of elongation) to that causing complete fracture of the structure. When strained, the alloy instantly and irreversibly transforms from a non-magnetic to a magnetic state. This transformation to ferromagnetism precisely and proportionally correlates with the strain. Upon repeated strain, the alloy remembers its maximum strain. The degree of strain is permanently recorded in the metal's properties and is easily readable with magnetometers.
These devices are non-destructive and passive, and are intended for use in strategically high-stress (high-strain) areas of a structure. A human operator can periodically visit the site with an inexpensive, hand-held magnetometer to read the sensor's memory, or operators can remain off-site and interrogate the sensor remotely by phone.
Data can be conveyed to a computer either at pre-set intervals or only when a strain exceeding a pre-set limit occurs. Contact:

Soff-Cut® System for Concrete Slab Control Joints
The Soff-Cut® system uses a patented technology for controlling random cracking in concrete slabs and pavements. The system allows early-entry, dry cut sawing of concrete joints. It is user
friendly and environmentally safe, and it promotes low maintenance. During the cutting process for controlling cracks in newly poured and finished concrete, a skid plate contacts the surface of the concrete adjacent to the saw blade. A special diamond blade cuts the aggregate at high speed without disturbing the aggregate inside the joint or on the surface. Only a dry powder that does not stick to the concrete is left on each side of the cut. The early use of this patented technology causes no chipping or spalling of the surface. This timing of the early-entry cutting process allows joints to be in place prior to development of major stresses in the concrete. It also increases the probability of cracks forming at the joint instead of the concrete seeking its own relief by forming a random crack on the surface.
