- Reference Points CAD Floor Plans The following is a list of the questions received in response to the solicitation and the site visit conducted on 25JULY2014, and the corresponding answer. QUESTION 1: Are there assigned values for reference points? RESPONSE 1: Attachment 1 lists five reference points. These points have been carefully surveyed and their precise latitude, longitude, and elevation coordinates have been determined. QUESTION 2: Is the 3mm precision requirement negotiable? If so, what is the new precision requirement? What confidence region is the 3mm to be evaluated at, i.e. 1 or 2 sigma? Does the 3mm precision only apply to the horizontal component or to the vertical component as well? If it only applies to the horizontal component, what is the precision requirement for the vertical component? Is the 3mm precision a relative or positional precision? If the 3mm is a relative precision, what is the positional precision requirement for each floor and the outside control with respect to the local coordinate system? RESPONSE 2: The precision requirement shall be at 1cm or less. We are interested in positional/absolute precision and not just relative precision. In addition, we are not interested in separating horizontal and vertical components. Rather, we are interested in 3D precision requirements. QUESTION 3: Will CAD files and/or floor plans be made available? RESPONSE 3: CAD files for building floor plans will be made available at fbo.gov. QUESTION 4: Is the 30 day performance period negotiable? RESPONSE 4: The performance period is hereby changed to the following: All work is to be completed and deliverables received no later than 90 days after the contractor's receipt of the order. QUESTION 5: What does the hazard review process entail? RESPONSE 5: The hazard review process is a local Standard Operating Procedure (Attachment 2), which the contractor shall abide by to ensure the safety of NIST and contractor personnel. QUESTION 6: Will the contractor be required to use Assisted-GPS methods to perform services? RESPONSE 6: The contractor is not specifically required to use the Assisted-GPS method to perform services. QUESTION 7: Diffraction of lasers hitting windows will distort results. Can windows be temporarily removed? RESPONSE 7: The windows cannot be removed. QUESTION 8: Will there be an opportunity to have portions of the glass pans removed and/or interior wall be cut for line of sight? RESPONSE 8: Neither glass panes can be removed nor interior walls cut. QUESTION 9: Are there any vertical face labels? RESPONSE 9: No. QUESTION 10: Is the contractor allowed to make their own face labels/markings? RESPONSE 10: Yes. Contractors may introduce face labels and markings in the performance of contract services as long as the markings are temporary. Contractors may also introduce auxiliary points outside of buildings being surveyed. QUESTION 11: Will a comprehensive list of test points, per building, be made available? RESPONSE 11: A list of test points is currently unavailable, but shall be made available. QUESTION 12: Will the contractor require an escort while performing services? How will the contractor access areas requiring a badge? RESPONSE 12: Contractors may be granted to perform contract services outside of normal business hours, provided they have a NIST employee escort and those providing contract services are on the NIST visitor registry. However, this is strongly discouraged, because it requires the presence of a NIST staff members outside of normal business hours or during weekends. This will only be allowed on an exceptional basis, maybe for a day or two, if it is absolutely needed. (The awardee would have to explain why this is necessary.) The contractors would not need an escort as long as they do their work during normal business hours. Arrangements will be made so that someone from NIST will open the door to the building they are working in on a particular day in the morning and after a lunch break. QUESTION 13: The buildings in which surveying is to take place appear to be occupied. Will that be an issue? Will certain buildings be required to be surveyed outside of normal business hours? Will there be a special operations schedule for this effort? RESPONSE 13: There will be a schedule for the work to be done. The schedule would specify which areas of a given building the contractors will be working in on a particular date. As long as the contractors follow the Standard Operating Procedures (SOP), there should not be an issue with people who work in the buildings. NIST does not believe there is any need to survey any of the buildings outside of the normal business hours. QUESTION 14: Will the floor labels be placed in such a way that a tripod mounted instrument will be able to be set up directly over the label? RESPONSE 14: Yes. However, all spaces may not provide sufficient room for tripods of all sizes. The points have been laid out in Building 222 with enough separation between walls and corners to make it possible to place a Leica GST120-9 tripod on each test point. QUESTION 15: Will the floor labels be placed in such a way that they will be inter-visible between two or more other labels? RESPONSE 15: Most points are visible from at least one other point. Whenever this is not the case, the contractors shall introduce one or more temporary, auxiliary points so that they can survey the location of a test point that is not visible from any other test point.
