Request for Information
Introduction
The Department of National Defence (DND) is performing industry benchmarking to find information concerning a CH 147F Chinook Tactical Aviation Light Weight Rapid Deployable Maintenance Facility (DMF) for Canadian Armed Forces (CAF) operations.
The DMF will enable maintenance (aircraft inspection and major repairs) activities.
The requirement is for two DMF’s. The DMF will be deployed for periods running between one and three months.
Required DMF performance characteristics
The DMF will be required to operate over a range of climatic zones from Equator to Arctic Circle and exposed to rugged military usage. It is expected to accommodate & enable the maintenance of one CH147 aircraft, with the following external dimensions:
o Total length: 99 feet (30.2 m)
o Overall fuselage length: 52 feet 1 inch (15.9 m)
o Fuselage width: 15 feet 9 inches (4.8 m)
o Rotor disc diameter: 60 feet (18.3 m)
o Back rotor maximum height: 18 feet 8 inches (5.7 m)
o Maximum CH147 weight that can be towed: 50,000 lbs (22,700 kg)
o Max load on the most loaded wheel on the soft / hard floor / ground inside theshelter 11,000 lbs (4,990 kg) (approximately 200 psi pressure on the floor)
Specifically, the DMF is expected to have the following performance characteristics:
- Code Compliance: The DMF to be designed in accordance with the National Building Code of Canada, the National Fire Code of Canada, and the Canadian Standards Association
- Critical internal dimensions:
o Minimum inside dimensions (clearance): 120 ft. x 105 ft. x 40 ft. (L x W x H).
o Minimum inside height (clearance): 40 feet (12.19m) measured from the top of the floor.
o Minimum dimensions of the gate (clearance): 75ft x 22.5ft (W x H)
o See Attachments #1 and #2 for the longitudinal and transversal minimum clearance requirements
o Operate in climate from -46C to +51C.
o Withstand Strong wind conditions (130 km/h sustained & gust with the gate closed and 80 km/h sustained & gust with the gate open), heavy snow loads, rain and moisture resistant, and fire resistant.
o Opening at one end to tow a CH147F with blades unfolded into the facility. The opening must be able to be closed once aircraft is within the facility.
o Inlet ports and air distribution system for heaters or air coolers.
o A separate air circulation ventilation system from any heaters or air coolers systems in case the heater or air coolers are not deployed.
o The facility must be able to accommodate an aircraft under cover within 18 hours of work over a two day period from beginning of setup. A further 18 hours of work over a two day period would be allowed to finish installation with lighting, doors, heaters setup, etc. Installation must be performed without the use of heavy equipment (i.e. forklift, zoom boom, ladders, Bobcat®). Installation will be performed by a crew of eight persons.
o 6 personnel doors of 72 inch width each.
o Anchoring capability in concrete, asphalt & in minimally prepared rough ground conditions with compact soil, sand, rock, and ice. Ground can be sloped as much as 1 degree both directions longitudinal and transversal.
o Optional: a corridor with a separate shelter to be used as lunch room/office space for 30 people to be attached to one of the 72 inch door.
o Expected life usage (storage and deployed) is 20 years.
o Electrical: Separate LED lighting and outlet electrical packages with individual isolated electrical generators to run the each electrical system. The largest sized generator to be used is 25 kW.
o Protection: Lightning and grounding protection systems outside of the shelter and two grounding points inside.
o Heating, Cooling & Ventilation: Diesel heaters and cooling conditioning with sufficient total output required to maintain a working temperature in all possible working environments (the heating system and cooling system must be 2 separate systems). The heating requirement is for a 50C temperature difference between minimum outside ambient temperature and the working temperature inside the shelter. The cooling requirement is for a 20C temperature difference between maximum outside ambient temperature and the working temperature inside the shelter.
o Flooring: Both possibilities of hard and soft type flooring system capable of withstanding the load weight of the aircraft and to accommodate one (1) degree of ground slope in both directions. Pressure on the floor 200 psi (all surface).
o Power: Power generator set to start up/power diesel heaters separate from the lighting and outlet generators. Any power required to run air conditions would be supplied by the CAF.
o Storage & Transportation: The DMF must be stored and transported inside 20 ft. ISO Type 1C (8ft x 8ft x 20ft) Convention for Safe Containers & TIR certified ISO sea worthy container(s). Due to truck movement limits the maximum gross weight of each container must be limited to 8165 kg.
o Fire Protection: Fire resistance materials and a fire suppression system are required.
Attachment #3, Statement of Operational Requirements elaborates on DND needs and provides suppliers with the necessary perspective.
Required Information
This Request for Information is not a solicitation. No contract will be awarded as a result of this Request for Information. However, information/ suggestions/ approaches submitted by industry will be analyzed and may be used in a future competitive solicitation. Suppliers are requested to provide the following information to demonstrate their ability to meet the required performance characteristics:
- Company experience in design and manufacture of similar DMF capability.
- Brochures and any other information / technical characteristics that could be of interest.
- Locations and contact information where similar DMF capabilities are presently being used & could be viewed; and
- Estimated price.
In addition, industry comments should address the following questions, as a minimum:
1. Is a commercial product and technology already available? If yes, will it need to be modified to meet DND needs? If no, will a new product need to be developed to meet the performance specifications?
2. What would be the approximate lead time for delivery once a contract is signed?
3. What will be the required size (L x W x H) of the structure based on the clearance provided? Please provide inside and outside dimensions of the structure (see the Attachments 1 & 2)
4. How will heavy snow / freezing rain conditions affect the structure of the shelter? Will DMF survive a heavy snowfall or freezing rain? What is company approach for those conditions?
5. How will ground conditions of 1 degree slope on both directions longitudinal and transversal affect installation? What is the flooring solution to accommodate 1 degree slope?
6. What are proposed solutions for flooring in arctic conditions (i.e.shelter installed over permafrost ground)?
7. What types of materials would be used in the construction of the shelter given an expected life of 20 years?
8. How translucent would the material be?
9. How feasible is a separate ventilation system and heating and cooling system?
10. What are the heating and cooling (BTU) required at the extreme ends of the temperature scale proposed?
11. What are the requirements for storage and transportation (i.e. number of ISO shipping containers)?
Delivery Date: Above-mentioned
The Crown retains the right to negotiate with suppliers on any procurement.
