The Square Kilometre Array is a global research infrastructure project to construct and operate a radio telescope observatory of unprecedented scale. The first stage of the project’s implementation (SKA1) has concluded its design phase and is about to begin construction in 2021. Composed of two interferometric arrays covering a frequency range of 50-350 MHz in Australia (SKA-LOW) and 350 MHz to 15.4 GHz in South Africa (SKA-MID), the observatory provides sensitivity and resolution which advance the currently available research infrastructure capabilities across a range of scientific frontiers. We describe the design development process for the SKA1, the antenna design and specifications, and the current construction planning and schedule.

This paper will describe the progress of the SKA-1 Telescope during the period from Preliminary Design Review to Critical Design Review. In addition to this, it will provide information on the management of the project with respect to managing cost and scope whilst working within a fixed cost cap. The paper will consider the balance between the technical choices made with the risk of delivering a large, distributed observatory across several continents. In addition, it will consider the challenges of carrying this out whilst developing the organisation towards an Inter-Governmental Organisation. It will consider, briefly, the key management tools used and the lessons learned.
