BEMO Roof System
Field Forming Information
- An operator will be provided with the BEMO Mobile Panel Forming Mills, (Panel, Curving and Tapering). If additional operators are required for simultaneous operations or extending shifts, other charges will apply
- The BEMO Mobile Panel Forming Mill and BEMO Mobile Panel Curving Mill are charged on a per day basis. Field Formed projects are quoted with a specific number of days included in the unit panel price.
- Your project has been quoted with an estimated number of roll-forming days and the appropriate equipment has been reserved for a specific period of time. The number of days has been calculated by taking into consideration the number of squares, length of panels, climate conditions, and project site conditions, etc. Therefore, it is imperative that the minimum recommended requirements for manpower and equipment be available from the outset of the roll-forming process. It is highly probable that the equipment is required on another project site immediately following the allotted time.
- The mobile panel former for the BEMO-Roof panels will manufacture panels at an average of 38m to 45m of panel per minute. This production rate should be accommodated through the use of appropriate man-power. When field forming on the ground, Manufacturer will provide the self-contained generator power source for the BEMO Mill as well as 90m of roller stands to support the straight and/or curved panels during the forming process. The BEMO generator holds approximately two-weeks worth of forming time fuel under normal operations.
- The mobile BEMO Curving Mill will require the roofing contractor to provide one (1) twenty-kilowatt 440 / 3-phase generator power source for the independent curving mill located within 15m of the curving process as well as a 827kpa compressor. BEMO generator holds approximately two-weeks worth of forming time fuel under normal operations.
- Roofing contractor must make provisions for bundling/crating all site formed panels as well as all hoisting (crane, spreader bar, manpower, permits, etc.) and scrap or trash container costs. Manufacturer can assist in determining these requirement.
- The possibility of roll-forming panels directly to the roof exists. Subject to availability, the Manufacturer can provide the special BEMO-Tilt Trailer (Please refer to the BEMO Field Roll-Form Slope Chart) to assist in placement of the panels throughout the duration of the job. If the manufacturer determines that it is economically feasible, for both parties, to roll the panels to the roof, it will be the roofing contractors' responsibility to provide the equipment (crane, manlifts, Skytraks, scissors lifts, 6m scaffold planks, 3m conveyor sections, etc.) and all required personnel for this operation other than as specifically indicated above. The roofing contractor will keep all savings relative to his estimated costs for hoisting, crating, etc.
- If the roofing contractor decides to hoist the BEMO-Roof Mill to the roof edge, please contact Manufacturer for specific guidelines, bonds and insurance requirements for this operation. The crane must be capable of handling the weight of the mill (18,143k) plus the weight of two coils (4,082k). Normally a 113 metric ton crane is required for this operation. (Each project has site specific requirements and we strongly recommend consulting with your crane supplier about lift and reach capacity for this operation.
- Roofing contractor must provide a forklift / Skytrak (forward lifter) and operator to efficiently maintain coil changes for the entire field forming process. When roll-forming to the ground, coil changes normally average 10 - 20 minutes each depending on the roofing contractors crew efficiency and positioning of the Mill. The BEMO coil tipper and de-coiler can handle a maximum weight of 2268k per steel coil and 1588k per aluminum coil. Coils for loading the BEMO Mill will be provided to the project site on skids with the eye vertical. When coils arrive on the project site, it is the roofing contractor's responsibility to unload and protect the metal until the site forming process begins.
- BEMO Mechanical Seamers operate at a variable controlled speed of 6m - 24m per minute. Roofer MUST hand crimp the installed BEMO panels, at the clip locations- DAILY, to avoid damage during high winds prior to the mechanical seaming process. BEMO manufacturer recommends using 12m per minute for estimating purposes. It is the Roofing Contractor's responsibility to notify the manufacturer immediately of any equipment problems. Seams must be clean prior to mechanical seaming process. Extension cords must be a minimum of 3.4mm and used within 30m of the power source.
- Manufacturer recommends, for panel handling, using a minimum of one (1) man per 4.5m of straight steel panel and (1) man per 6m of straight aluminum panel.
- Manufacturer recommends, for panel handling, using a minimum of one (1) man per 4.5m of curved steel, aluminum, copper or zinc panel.
- CURVING NOTE: BEMO Roof Panels are formed in the straight and horizontal plane when exiting the roll-former. A separate operation is required to curve the straight panels. Make sure to include the necessary manpower for BOTH operations on a single square foot of curved material.
- The curving process, once "dialed-in" will operate at approximately 15.25m per minute. Refer to the above guidelines for the minimum recommended manpower requirements. NOTE: Roofing contractor should make provisions for four (4) hours of crew time startup (number of men determined by the above guidelines) for every change in the radius of the mechanically curved panels. Once the tangent points and stretch forming parameters are established the curving process will operate as indicated above.
- Union Personnel Requirements: Manufacturer's employees do not have union affiliations for moving the truck/trailer/BEMO mill around the project site nor individuals for the regular weekly/daily fueling and/or maintenance of the generators.
- Manufacturer's roll forming personnel are Non-Union employees. Any costs associated with union fees, project agreements, pension funds, etc. will be paid by and at the expense of the Roofing Contractor. Manufacturer will pay its roll forming personnel the prevailing wage rates on Public Works projects.
- Many finished metal PRODUCTS - Quick Menu include a protective strippable film or paper interleaving. If the project is supplied with either paper interleaving or protective strippable film, it is the roofing contractors responsibility to provide the manpower for removal as well as all associated disposal costs.
- BEMO can offer the services of a Field Technical Representative at a per diem rate, prior to the scheduled roll-form, during the roll-form or during installation to help maximize manpower efficiencies, make production and installation recommendations and assist in general BEMO application.
