Controlled Demolition: Asbestos Abatement

One of the first steps in any demolition project is to identify hazardous materials, including asbestos, that require abatement. Asbestos was widely used in an array of building materials – pipe insulation, fittings, caulk, ceiling and floor tile, etc. – before it was banned in 1981, and the majority of commercial and industrial buildings erected before that time contained asbestos in some shape or form. A substantial amount of ACMs, including asbestos mastic waterproofing, were identified in the circa-1949 pharmaceutical facility, 80 percent of which was slated for demolition. A containment remediation plan was developed and executed before, during, and after demolition activities of the large steel and masonry structure.

The entire demolition area was enclosed with a barrier and labeled with signage barring unauthorized entry before work could commence, and all personnel and equipment were required to enter and exit through one designated access point. Decontamination areas were set up for cleaning heavy equipment prior to leaving the abatement area and a personal decontamination unit was installed for workers to use when exiting the site.

Pre-demolition abatement activities took place on all exposed friable and non-friable materials. As the demolition crews progressed, steel building members containing non-friable asbestos mastic were removed and segregated for further abatement. The remaining abated building components were then removed as recycled materials.

What is a Critical Lift?

In the crane and rigging industry, a critical lift is a rigging activity in which a comprehensive plan is necessary to minimize risk of crane failure or catastrophic loss. As for the term “critical lift”, though there is no universally-accepted single definition or industry standard used for categorization, there are a number of items that are common to various agencies and rigging industry associations. OSHA characterizes the definition thusly: a critical lift is one that a) exceeds 75% of the rated capacity of the crane or derrick, or b) requires the use of more than one crane or derrick. Various other government agencies and industry associations such as NIOSH, the US Army Corps of Engineers, and the Department of Energy use their own criteria to classify a critical lift that will require development of a critical lift plan. Following are some of the most commonly-appearing elements of a critical lift (keeping in mind that specific projects have unique conditions that should be taken into consideration):

Any lift that requires more than one crane

Loads exceeding 75% of a crane’s rated capacity

Lifting of personnel

Load suspension above rigging personnel

Loads not in view of the crane operator

Loads of exceptional value

Loads that have the potential for becoming unstable during rigging

If it is determined that a lift is to be considered critical, a detailed critical lift plan must be prepared. Following an analysis by qualified rigging personnel, a critical lift plan should include details such as size and weight of the load, equipment needed, boom length and angle, crane and boom positioning, required personnel, crane capacity, sequencing, and environmental conditions, among others. The critical lift plan should be thoroughly reviewed with the rigging crew prior to the lift to ensure that all necessary details and required safety procedures are in place.

R. Baker & Son, a leading rigging contractor since 1936, has conducted countless critical lifts for a vast array of clients in a variety of industries throughout the U.S., Canada and Puerto Rico. We are staffed by experienced master riggers, engineers, and skilled rigging tradespersons and equipped with all of the necessary equipment to handle even the most complex rigging projects with the highest safety standards.

Rigging Near Overhead Powerlines

Crane operation near overhead power lines is one of the most dangerous jobs a rigging crew can undertake. In fact, electrocution is the number one cause of crane-related fatalities, making compliance with OSHA standards and guidelines absolutely crucial when working in close proximity to overhead power lines.

Before equipment is brought to a jobsite near overhead power lines, a 360-degree hazard assessment inside the work zone must be completed. If it is determined that a crane could exceed minimum required distances, further action is required by the contractor. The first option is to coordinate with the power company to have the lines de-energized and visibly grounded. Line owners will sometimes opt to move the lines so that minimum clearance distance can be achieved. Both options require some preplanning as it may take some time to complete the necessary work.

OSHA requirements for working near overhead power lines that are not de-energized are clear cut. For power lines 50 kV or less, all parts of the crane, boom, rigging equipment, and loads carried must be kept at least 10 ft. away. This distance increases to 20 ft. for lines rated 50 kV to 350 kV, and 50 ft. for lines over 350 kV. If the voltage cannot be determined, cranes and rigging equipment must be kept at least 45 ft. away. A planning meeting with the crane operator and riggers must be conducted to review the location of the power lines and implement a rigging plan to prevent encroachment. All tag lines used must be non-conductive to prevent electrocution. An elevated warning line, barricade or line of electrocution hazard warning signs equipped with high-visibility flags must be erected 20 ft. from the power line in view of the crane operator. In addition, the rigging contractor must utilize at least one of the following: a dedicated spotter, proximity alarm, range control device, range of motion limiting device, and/or insulating link.

Crane operators and rigging crew members should be trained to work safely near overhead power lines and how to react if safety measures fail and contact is made. Dedicated spotters have the important responsibility to ensure that the minimum distance is not breach and thus must receive special training.

Rigging of Modular Prefabricated Pharmaceutical Plants

Installation of prefabricated modules is becoming increasingly common in the pharmaceutical industry. R. Baker & Son has been instrumental in offloading, rigging, setting in place and connecting numerous modular pre-fabricated pharmaceutical manufacturing facilities.

Modular pharmaceutical plants are comprised of pre-engineered units that are constructed off-site and test-run under controlled conditions while exacting on-site preparation of the facility takes place. Once completed, the modules are shipped to the construction site and carefully rigged into the structural compartments. Installation of the structure’s process and utility systems must be precise to ensure quick, problem-free rigging, assembly, commissioning and validation of the modular plant. Advantages of this type of construction are improved quality, better cost control, and significant reduction in project completion time.

R. Baker & Son has been a key player in the rigging and installation of numerous modular pharmaceutical facilities. While the rigging is usually a relatively smooth process on these projects, complications and challenges due to interface issues between modules and the structure are not uncommon, which is why a first-rate rigging plan and a highly experienced contractor like R. Baker & Son are vital to the success of these projects.

Dismantling Clean and Green

Dismantling projects pose distinctly different sets of challenges depending on the industry. On pharmaceuticals projects, biological and chemical contaminants must be eliminated before dismantling can begin.

Pharmaceutical plants contain a variety of areas and equipment that may contain hazardous substances, growths, or residues. Epoxy countertops, sinks, fume hoods, biosafety cabinets, autoclaves, etc., can be found in laboratories. Process suites, which can differ widely depending on their function, may contain process piping, tanks, isolators, lyophilizers, downflow booths, and various others. Plant owners, contractors, process managers, industrial hygienists, and environment service providers must work together to identify areas and items that require cleaning and/or decontamination.

Once familiarized with the facility and its processes, the industrial hygienist will conduct thorough testing for contaminants and prescribe the precise decontamination process that must occur. This is done not only to ensure environmental and worker safety, but also to ready fixtures and equipment for reuse or resale. Decontaminated areas are then retested by the industrial hygienist and verified ready for dismantlement. Because work scope can sometimes change as a project progresses, continued teamwork among plant owners, industrial hygienists, and project contractors is essential to ensuring that newly identified problem areas are promptly tested and remediated before dismantlement.

R. Baker & Son All Industrial Services, as a multifaceted contractor whose specialties include both dismantling and environment services, can perform both the remediation of the facility as well as the dismantlement. Our dismantlement services include: decommissioning of equipment, rigging and match marking, machinery moving and transportation, plant relocation, reinstallation and millwright services, and asset recovery, and equipment resale. Environmental services include: surface cleaning, pipeline cleaning and pigging, column and vessel cleaning, tank cleaning, line flushing and first line breaks, HVAC and duct cleaning, non-ACM insulation removal, HEPA vacuum services, and power washing and steam cleaning of pipes and equipment.

Hydraulics: The Force Behind Rigging & Demolition

Hydraulics is the workhorse of modern rigging and demolition, providing the muscles that lift, steer and drive the cranes, excavators, breakers, and hammers used each day. But hydraulics is not a recent innovation. In fact, examples of hydraulic power go back more than 2,000 years to ancient Rome, where it was used in water clocks, water wheels and pumping systems. In the 17th century, French mathematician Blaise Pascal made the groundbreaking discovery that serves as the basis for the science of hydraulics.

Pascal’s principle states that when pressure is exerted at any point to a confined, incompressible fluid, there is an equal increase in pressure at every other point in the container. Thus, when one piston in a simple hydraulic system is pushed down, the other piston is pushed up. Applied to a more complex hydraulic system, Pascal’s principle allows forces to be multiplied. If a second piston has an area ten times that of the first, the force on the second piston is ten times greater, because the pressure is equally distributed on the larger piston’s entire surface area. The larger the surface of the second piston is in relation to the first, the greater the mechanical advantage.

Hydraulics have been used in rigging and demolition since the mid-19th century, when cranes powered by water were used to load coal onto barges. Nowadays, oil is the fluid most commonly used in hydraulic equipment. On any given day, hydraulic equipment is present throughout R. Baker rigging and demolition projects, powering crane booms, telescoping sections, and outriggers, excavator steering, booms and attachments, and on loaders, dump trucks, lulls, and hydrauic hammers. Wherever strength and force is required in our industry, hydraulics are overwhelmingly the power of choice.

R. Baker & Son - Airlock for Clean Room Demo Project:

Interior demolition projects pose challenges of all kinds, some much more challenging than others. The challenge on one particular R. Baker & Son project was to perform extensive interior demolition in a space adjacent to multiple class-100 cleanrooms. The facility owners required that there could be no interruption to facility operation, which ran twenty-four hours a day, and that demolition activities would have no negative impact on the clean spaces.

To ensure that no dust or particulates would infiltrate the cleanrooms, R. Baker & Son’s team of demolition experts devised an ingenious vacuum airlock. A 35 ft. wide by 16 ft. high by 18-inch wide cavity was constructed from aluminum studs and drywall. The interior of the airlock was sealed with wall panels specially designed for clean rooms, and several ¾-inch holes were bored into both sides of the cavity to draw air in. Three HEPA exhaust fans were installed on the dirty side, drawing 1,500 CFM into the sealed cavity to create a vacuum. Differential pressure gauges installed on both sides of the void showed a constant negative pressure of a half inch, effectively preventing particulates from migrating from the work area to the clean spaces. The owner was fully satisfied with R. Baker & Son’s resourceful solution, and cleanrooms remained contaminant-free through the duration of the demolition project.

7 Phase Enabling Project

Critical demolition projects, such as medical facilities, pharmaceutical plants, data centers, advanced manufacturing, etc., require enabling work for the project to move forward. This was the case in a large seven-phase enabling project R. Baker & Son recently completed for a pharmaceutical plant in New Jersey.

It was imperative on this particular project that ongoing plant operations could continue without interruption. This requirement added another level of complexity to the planning and execution of the project and required close cooperation with the client during an extensive planning process, as well as through the application of value engineering to keep project costs in check. Through this intense scrutiny it was determined that the project would proceed with seven meticulously-planned enabling phases. These phases included demolition and rigging performed by R. Baker & Son as well as electrical, mechanical, site utility work, and excavation performed by other subcontractors.

The phases consisted of the following:

*Because of the critical nature of the enabling projects, some exploratory work was required to locate and trace utilities such as electrical feeders, steam and condensate lines, and waste water.

*New utility lines were run and tied in during off-hours and weekends so that the identified existing utility lines could be demoed to make way for new foundations.

*Demolition of an existing office area was performed to make way for a temporary loading dock, and the existing loading dock was demoed to be replaced by a new mechanical room.

*Once the new mechanical room was up and running, the facility’s second floor mechanical room was demolished.

*A new generator and cooling towers were installed on the north side of the building and tied into the facility so that existing units could be demoed and removed to make way for a new building entranceway.

*A new foundation and façade was added to the south side of the building so that the existing exterior could be removed in to make way for a new data center, MDF, and IDF.

*Select demolition was performed on specific office areas and corridors so that new utilities, such as chilled water, reheat, electrical, and fiber-optic lines, could be run to support the new facility.
Once the exacting enabling phases had been completed, without interrupting operations as required by the client, the remaining phases of demolition and construction proceeded smoothly and on schedule. The project was ultimately completed successfully to the client’s full satisfaction.

3D Rigging and Routing

Every sizable project that involves the installation of large equipment in or outside a building requires a rigging and routing plan. It wasn’t long ago that rigging and routing plans were achieved with hand-measurements, two-dimensional drawings, and paper cutouts. Now, rigging and routing plans are often developed building information modeling (BIM).

BIM modeling is achieved through a combination of existing data and 3D laser scanning. The data is used to develop models detailing precise locations of existing and planned structural features, piping, ductwork, equipment, etc., down to the fraction of an inch. These 3D models are combined with 4D project information – equipment that is to be installed, including physical dimensions, weight, how many pieces, and when it will arrive – to arrive at a rigging and routing plan. BIM can provide critical information on features that may need to be temporarily delayed, moved, or removed to accommodate the rigging of large equipment.  Using BIM for developing rigging and routing plans allows for greater accuracy, helps identify potential logistical problems, and keeps project costs down by eliminating delays due to planning errors.

Construction Machinery at NJ's Diggerland

Rigging and demolition is a serious business. Crane and heavy equipment operators, like those here at R. Baker & Son, are highly-trained, experienced specialists tasked with using powerful machines to perform challenging and potentially dangerous feats. It is a serious job, indeed, but even the most consummate rigging and demolition professionals still feel a certain thrill when piloting their massive machinery. They are living out their childhood fantasy.

Nowadays, kids don’t have to wait until adulthood to experience their construction and demolition dreams. At Diggerland USA, a hands-on construction themed adventure park located in West Berlin, New Jersey, kids and adults alike can drive, ride, and operate actual heavy machinery. Though there are no cranes for rigging enthusiasts, visitors can drive backhoes, skid steers, and steam rollers, take an off-road drive in an ARGO amphibious UTV, or dig a hole with an excavator. Mini-excavator attractions challenge riders to snatch rubber ducks from a pond, dig up hidden treasures, and knock over bowling pins. Diggerland has even converted heavy equipment into amusement rides, some meandering and gently turning in circles, others spinning and soaring for the less faint-of-heart. Diggerland also features a rock wall, a ropes course, a stunt show, an arcade, and a padded playground for tykes.

For the 18-and-over crowd, Diggerland recently unveiled Diggerland XL, where adults can operate unrestricted, full-size equipment with 1-on-1 instruction. Grownups can play a giant game of Jenga with a 12-ton wheel loader, dig holes and play basketball with a 26-ton excavator, and navigate an obstacle course that requires moving tires and grading earth with an 18-ton dozer.

Diggerland is situated in southwest New Jersey in West Berlin, a twenty minute drive from Philadelphia and about an hour and a half from New York. An R. Baker & Son demolition team member and his wife visited Diggerland recently with their three children and described their experience as “an absolute blast” that was well worth the trip.  www.diggerlandusa.com
