We would like some clarification on your Request. You state that you would like to build it and we quote "close proximity/direct vicinity of Planet Sprague".
How close is close/direct?
In accordance with the Bretonian Charter of Interstellar Law, Chapter 5 - Base Construction and Zoning, Sub-section - 5.4 - Base Operational Regulations, any "Bases must be no closer than 10K from any existing Base or Jump Gate, unless Special Permission is granted by the War Cabinet". The Docking Ring would fall in to this category.
If this is what you require, then we will need to approach, on your behalf, the War Cabinet and seek a Special Dispensation.
Please let us know, at the earliest opportunity, how you would like to proceed.
