HomeMy WebLinkAboutQuestions and Responses_RFQ GPS Data CollectionQuestion Response Would you be able to share which departments the selection committee of 3 represent within the City (Ie, GIS, Engineering, Roads)?Generally, the Departments will include Water, Sewer, Storm, Streets and Parks The coordinate system data requirement specifies either UTM zone 12 NAD83(2011) or MTSP NAD83(2011) meters horizontally, NAVD88 vertically.  However, RMTCRS Bobcat Low Distortion Projection ( EPSG-7126 or 7116)   would allow for seamless data integration without grid to ground issues across multiple departments and software platforms. Can this coordinate system be used as for the data output? (I can send more info on this if needed) We will not accept data that has not been delivered in our defined coordinate systems and datums. Are the assets for collection- presumed to be wet utilities primarily, simply the Valve and manhole cover locations or are pipe invert measurements required attributes as well that need to meet the 2cm spec? Pipe invert measurements may be required as part of the data collection process. In responding to this RFQ do we need to provide our rates and fees, or is this only after being scored as qualified?   I just wanted more insight on what the city is looking for on rates and fees, ie an hourly rate for a professional land surveyor, or field technician and equipment fees, or audited overhead rates, etc.  Firms scored as Qualified will be asked to provide a proposal for rates and fees and sign a term contract to provide the City services at those rates. Qualified firms with standing term contracts will be contacted by the Strategic Services Department as projects arise. Projects covered by these contracts will have a maximum value of $79,999. (Page 5, paragraph 7 of hte RFQ). We are not looking for a Land Surveyor. We are looking for a Technician that is qualified to collect GPS data with equipment that can fulfill the accuracy standard of 2cm. Does the city have a preferred asset point deliverable format?  We have done numerous County CADNSDI control projects across the state, and the state library has a good template for submitting control data that details attributes and provides accuracy, alternate coordinate formats etc that they can easily upload into their cadastral fabric adjustment.  Is the city deliverable similar?  Do you have an example of previous term data deliverable that we could see? I can send the state library form if interested. The City of Bozeman has a schema for each asset that will be collected and the expectation is that the data will be delivered in both UTM zone 12 NAD83(2011) or MTSP NAD83(2011) meters horizontally, NAVD88 vertically. The assets that will need to be collected and the schema for said data will be provided at the time the project begins. When trying to accomplish a 2cm accuracy and only specifying GPS as a method of measurement, it has to be acknowledged that over a site as large as COB city limits, there are areas where city infrastructure exists that is either under dense canopy or adjacent to tall buildings and the effect of multipath, even on modern state of the art GPS equipment will push the data quality beyond that accuracy spec.  We would take the approach of using a GNSS derived baseline to use conventional equipment such as a total station to collect data where multipath conditions exist, but feel as though the RFQ should address this, as it would be an unfair disadvantage to firms truly providing professional results that might take slightly longer under these conditions. This approach would be acceptable to the City of Bozeman as long as the provided data falls within the 2cm accuracy for collected data. Do you want staff resumes included, and if so, do they count against the 10-page limit or is it fine if they’re in an appendix?Please limit the number of pages to 10 including staff resumes. The first page, and the website, both say must be submitted by 5:00pm MST and later in the RFQ under section IV it states 3:00pm MST. Which is the preferred deadline time?The time being listed differently is a mistake on my part. I will work with our City Clerk to make sure this is corrected and update you when I have a confirmed time. I apologize for any confusion and will get you an answer as soon as I can (hopefully by EOB today). What is going to be modeled from the point data acquired? We are a firm that has professional land surveyors, engineers as well as GIS technicians, so we understand survey-grade data versus GIS resource grade. The accuracy required of 2 cm is definitely survey grade typically used for engineering design, so we wonder why this accuracy is requested for GIS type data? I think I understand your question, but if my response doesn’t answer the question let me know. Depending on the project the data that the City would ask to be collected could include water/sewer/storm data. The City currently models water and sewer capacity using GIS data, and that data requires a high degree of accuracy when it is integrated into the models.

Not all projects will include an elevation component. In the event that a very accurate vertical elevation (like inverts) is required the request will be called out in the Scope of Work in the Task Order associated with the project. Will the point data to be acquired include multiple fields/attributes for the asset mapped, or will a single description be sufficient?Whether or not field attribution will be required will depend on the project and will be called out in Scope of Work in the Task Order associated with the project. If attribution is required the City will provide the schema for the data that will need to be returned for each layer and the format that the returned data will need to be in (for example an ESRI file geodatabase). What is the timeline for qualifying as a consultant that can receive a contract for this work, and what is the estimated timeline for issuing a contract for this work? From the RFQ (page 6): Selection Timeline Advertising dates: August 3 and 10, 2024 Receipt of RFQs: No later than 3:00 p.m. MST August 22, 2024 RFQ Review Complete by Committee: August 30, 2024 Interviews: September 2 - 6, 2024 Selection: September 16, 2024 Once the selection process has been completed and the contract(s) go(es) to the Commission for approval the Professional Services Agreement will indicate the option to extend the contract available for up to 3 years.
