** 254/255/Resident Firm Certification forms may be submitted electronically, in a COMBINED pdf format, to the point of contact listed in the specific Professional Services Request. If you choose to submit electronically PLEASE submit a complete package for EACH project, including 254s for prime and sub-consultants as well as your 255 and Resident Firm Certification (if applicable) in a single combined PDF. Please send a separate email for each project you're submitting materials for along with contact information including email, phone number and primary office location doing the work.**

If you choose to submit via mail, please provide two (2) copies each of your 254, 255 and Resident Firm Certification form (if applicable) as well as any 254s of sub-consultants. Please submit separate documents on each project for which you would like to be considered. Copies of forms 254, 255 and the Wyoming Resident Firm Certification form may be accessed below.

An email address MUST be provided for distribution of RFP's and correspondence, see box #4 on form 254. Firms offering professional engineering services must provide their Board issued Wyoming license number.

Consultants will be selected by the SEO to prepare proposals, as per W.S. 9-23-104 and W.S. 9-23-105 using information contained in the SOQ of the prime consultant and any sub-consultants, the SOI of the prime consultant, and the Wyoming Resident Firm Certification form (if applicable).

Questions.

Q1. Please confirm the actual due date time of the RFP. 

A1. The RFPs are due on May 4th at 10 am

Q2. Please provide details on the interview process including scheduling

A2. The SEO is currently in the process of reaching out to the prime consultants to set up a time next week during the time slots of Wednesday, May 6, 9-12pm, 1-5pm, and Friday May 8, 12:30-3pm.

Interviews can be in person, hybrid, or completely virtual. They will consist of a 30 minute presentation from the consultant on the project plan, interview questions, followed by discussion of the project details and budget.

Q3. It was mentioned that there was a research project conducted in China. Can you provide the link?

A3.    https://www.sciencedirect.com/science/article/abs/pii/S0378377416301056?__cf_chl_tk=Qdetj056j3jNpuSOdH7Mq2C.m.Od1MPerf5Oo5OHbpg-1777333137-1.0.1.1-J_a.7Rroa.K27BXRisuIqqGK3yKi3erYunEyjfXwH4I

This article has not been reviewed and may not provide a valid method.

Q4. Will high resolution terrain/topography (i.e., LiDAR or comparable) be available for the proposed project sites? If so, what is the vertical accuracy of the data?

A4. The LiDAR data that is available is from the Wyoming LiDAR Data Portal (https://lidar.wygisc.org/) and comes in 2 ft vertical resolution. USGS also provides LiDAR for the area in 1 m vertical accuracy (https://apps.nationalmap.gov/lidar-explorer/#/). We have never used this data for other projects and cannot confirm how "useable" it is.  

Q5. What are the spatial sizes (acres) and dimensions of the proposed project sites?

A5. Site sizes, based solely on the property boundary size and not guaranteed, may range from approximately 500 to 2000 acres, but smaller study areas are at the discretion of the consultant, if they think they are adequate to accomplish their goals. 

Q6. Are proposed project sites flood or sprinkler irrigated, or both?

A6. Flood irrigated

Q7. Does WSEO expect sufficient surface water gaging operations to be already available, or will the contractor need to install/rate and operate surface gaging on rivers, ditches, etc.?

A7. It is uncertain at this time. This will depend on the location chosen. The existing SEO stream and ditch gaging is shown at https://greenriverbasin.org/. USGS stream gaging will also be available in certain areas. But, again it is not guaranteed that the site that the SEO and contractor decide upon will have these in the necessary locations.

Q8. Are ditches and associated irrigation infrastructure adequately captured/mapped by existing high-resolution NHD?

A8. No. Some, but not all, of the ditches may have been hand digitized by the SEO and available in shapefile format.

Q9. Has canal seepage been quantified at any of the proposed project sites?

A9. No.

Q10. Will the project sites be coincident with localized/operating meteorological stations for characterizing effective precipitation. If so, what other types of information are available from these stations?

A10. There are 10 WACNet met stations in the Green River Basin, as shown on this link (https://www.wrds.uwyo.edu/WACNet/WAC.html). Four are located in the general area including Daniel 10NW, Daniel 8S, Big Piney 11W, and LaBarge 2S. They are equipped with temperature, relative humidity, Solar radiation, wind velocity (sufficient for calculating Penman-Monteith reference ET), as well as precipitation  and soil moisture. 

There are also two eddy covariance sites in the general area with data available to the WSEO, including one owned by Bureau of Reclamation in North Piney Creek drainage and one owned by the UCRC near Cora. In addition to eddy covariance sensors, these stations have similar parameters to the WACNet stations. 

Effective precipitation data is also modeled annually by Reclamation using the ET Demands a rootzone water balance method.   

Q11. Does WSEO expect field instrumentation/equipment to be purchased for the project, or will instrumentation be made available to the contractor?

A11. The WSEO itself does not plan to purchase any equipment for the study.

Q12.  Is there desire from the WSEO to assess reliability of OpenET estimates using eddy covariance or other ET methods?

A12. No, unless the consultant thinks it is necessary to accomplish the goals of the project.  

Q13. What is the accepted land use layer by Wyoming State Engineer’s office for defining crop and non-cropped areas?

A13. The WSEO can provide a water rights points of use GIS layer. 

Q14. Are SSURGO soils data layers expected to be fully complete for proposed study sites?

A14. The WSEO has not evaluated the area for database the SSRUGO completeness.

Q15. Has there been any prior characterization of groundwater levels at the proposed project sites?

A15. The SEO does not have information on groundwater levels, aside from what might be in the literature.

Q16. Does the WSEO expect that groundwater potentiometric surfaces/gradients are adequately resolvable without modeling? In other words, large sites will need many piezometers, or alternatively modeled potentiometric surfaces to accurately represent water levels. Are sites small and simple enough that water tables can be characterized solely with a reasonably sized piezometer observation network or should the contractor expect the need to develop groundwater models to interpolate levels between piezometers due to complexity or a large project area?

A16. This is difficult to say and will likely rely on the recommendation of the consultant. Site sizes, based solely on the property boundary size, may range from approximately 500 to 2000 acres, but smaller study areas are at the discretion of the consultant, if they think they are adequate to accomplish their goals. 

Q17. Does the WSEO office support the use of tracers/stable isotopes for vegetation/source use studies?

A17. Yes, assuming we have support of the landowner.

Q18. Does WSEO expect data feeds from monitoring network to be compatible with the existing AQUARIUS Web Portal data flows?

A18. While real-time data can be hosted on the WSEO's website, and could be preferrable for certain data, it is not a requirement. However, the WSEO team would like to have access to the data.
