CLOSED: Request for Proposals: Peace Region Magnetics Structural Interpretation, NE BC

 
RFP is CLOSED


Geoscience BC is pleased to issue a new Request for Proposals (RFP) : Peace Region Magnetics Structural Interpretation, NE BC


Aquifers in the Peace Region are poorly understood. A wide range of stakeholders including provincial ministries and agencies, local governments, commercial water users and First Nations, as well as the general public, need detailed and unbiased information about existing water resources to make appropriate policies, regulations and permit decisions as well as to support public discussion on issues related to water use.

In order to gain additional information on aquifers in the region, an airborne electromagnetic (EM) survey conducted by SkyTEM, was carried out in the north Peace Region of NE British Columbia to locate potential shallow groundwater aquifers within the area. The airborne EM survey was designed to provide the data required to interpret potential Quaternary and bedrock aquifers within the survey area and to provide a map of the Quaternary-bedrock interface, i.e. Quaternary thickness. Following standard airborne EM practices, SkyTEM also collected magnetic data during the survey.

Geoscience BC is now seeking proponents to conduct a structural interpretation of magnetic data collected from the SkyTEM survey. The objective of the proposal is to interpret crystalline basement with respect to structure, lineaments, faults, intrusions, lithology (i.e. magnetic susceptibility) and, if possible, calculate depth-to-basement.

  • Peace Region Magnetics Structural Interpretation, Northeast BC - RFP Document

    Proposals should be submitted by email no later than 12 pm (PST) on June 13th, 2016.



    CLARIFICATIONS on the RFP - Based on Enquiries Received to June 10th, 2016

    • This project should be completed before October 31, 2016.

    • Technical information required can be broken into:

    1) standard (off the shelf) information which is available to everyone, for example calculating the vertical derivative, etc. If a particular software package is used, that information would be useful.

    2) special processes, if used, which are not standard should at least have a reference or at least an explanation of what it does. Complex formulas are not expected.

    • RTP removes the asymmetry in magnetic anomalies so reducing to the pole places the peak of a magnetic anomaly at the centre of the magnetic body producing the anomaly. It is not necessary to reduce to the pole but sometimes makes it easier to define the location of faults, etc. (June 8)

    • The wording in the RFP clearly says "if depth estimates are provided then ...". Therefore, Geoscience BC is relying on the contractor to assess the data and make that decision. (June 8)

    • PDF map products at 1:50,000 scale are preferred. (June 8)

    • Derivative products required are: first vertical derivative, horizontal gradient, analytic derivative and several bandpass filters designed to look at magnetic features within the sedimentary section and within the shallow basement. Additional products that the proponent deems helpful to their interpretation should be included as well. (June 8)
