- Description
- The following questions and answers are provided for informational purposes only: Question #1: Are the dimensions referenced in the solicitation absolute or is there some flexibility in the enclosure sizes? If there is some flexibility, can the enclosure size be expressed in 'not to exceed' dimensions? Answer #1: Chamber sizes are absolute in order to maximize our research space Question #2: Given the precise temperature / humidity control desired across the 4 - 40 deg C operating range, does the user envision this chamber to be 'air tight'? If so, is there a need / concern for barometric pressure compensation? Answer #2: No. The chambers are not required to be air tight. Barometric pressure compensation is not required. Question #3: The specification makes reference to a 'highly corrosive environment'; is this corrosive element inside or outside the chamber? Are there any other known material sensitivity which should be considered (i.e. - rubber door seals, etc..)? Can the user provide a description of the environment in which the chambers are to function (i.e. - min / max temp., humidity, etc..) Answer #3: The main corrosive will be salt corrosion from seawater. Exposure will occur on both the inside and outside of the chambers. Min/max temps and humidity ranges are provided in the specifications but normal operation will generally be at an ave rage temperature of ~23°C at maximum humidity. Question #4: Are there any particular needs re. door(s) size? Sealing? Window size? Internal release mechanism for lock? Answer #4: The door should be a single door with a mimimum 36 in. width. Window size should be a minimum of 1 foot square. Question #5: Reference is made that power shall be 208 VAC: is this single or multi-phase power? Is there a max current demand specified? Answer #5: The console power can be up to 20 amp (120/208 volts) single or three phase. Condenser power can be up to 30 amps (120/208 volts) single or three phase Question #6: Given the desire for both expansion capability and individual multi-day chamber programmability, would the user consider the possibility of utilizing individual PC-based data acquisition and control systems for each chamber? These individual PCs could then be linked via a LAN-network to consolidate test reports, etc... Answer #6: Yes. This is feasible although an integrated computer for each chamber would be desirable. Question #7: The specification makes reference to a capability to accept new sensors; can the user specify the types of data which are to be captured and displayed in addition to / as a function of temperature & humidity? Answer #7: This is an uncertain at this point. 4-20 mA sensor support is desirable. Question #8: What, if any, system or component calibration shall be required? Shall this calibration routine be automated? Answer #8: If system calibration is required then an automated system would be desirable. Question #9: Rather than internally-mounted lighting, would externally-mounted lights over windows in the roof be acceptable? Answer #9: Internally lighting is desired but external lights should work if they can be fit within the ~2' clearance above the chamber. Question #10: Are there any particular needs relating to the chamber 110 VAC outlets (i.e. - more than 20 A?; Hazard-rated or explosion-proof?) Are there any other internal chamber needs? Sampling probes? Thermo-couples? Answer #10: 115-120V/20 amp circuits are the only requirement. Question #11: Is there any site visit and /or direct interaction with the user community planned / possible before the award date? Answer #11: A site visit prior to the award date can be arranged by contacting J. Daniel Farrar at 601-634-2118 or by e-mail at farrarj2@wes.army.mil. Question #12: Are there any plans available showing location of the rooms and the condensing units? A nswer #12: A drawing of the lab is available by contacting Anitra Wilson at Anitra.D.Wilson@mvk02.usace.army.mil or 601-631-5341. The drawing was done for internal discussion only so it is not exactly to scale although indicated measurements are generally correct. Each square represents roughly 1 foot. Question#13: The chambers are specified to include a door with a window and locking handle. Is there a minimum or maximum size for this door? Answer #13: Minimum width is 36 inches. NOTE: THIS NOTICE WAS NOT POSTED TO FEDBIZOPPS ON THE DATE INDICATED IN THE NOTICE ITSELF (01-AUG-2006); HOWEVER, IT DID APPEAR IN THE FEDBIZOPPS FTP FEED ON THIS DATE.
