Technology selection System Design

including operational – construction tradeoffs

Science Performance vs Reference Science Mission Total cost estimate for Baseline Design (incl.

contingency) Risk assessment Design and deployment plan Top-level build schedule Upgrade paths

WP2 approach Streamline WP2 Description of Work

Move from 40 technology development tasks, including an ill-defined ‘IVS’ to assembly and verification of large SKA sub-systems

Easily evaluated by EC and Funding Agencies/Governments

MoAs with organisations and institutes

WP3 – Additional Site Studies

Inform decision-making process for site selection

– Carry out further RFI measurements (in progress)

– RQZ (in progress)– Investigate infrastructure deployment

costs and timescales– Detailed risk analysis– Array configuration (in progress)– Ionosphere (in progress)– Tropospheric water vapour

WP4, WP5

WP4 – Governance and Legal Framework (led by NWO, NL)Study of options for viable models of governance and a

legal framework for SKA during construction and operation

Interim legal entity for SPDO during PrepSKA?

WP5 – SKA Procurement and industrial involvement (led by INAF, Italy)Lay out options for procurementInvestigation of the optimum way to involve industry in

the global, regional and national contexts

WP6, WP7 WP6 – Developing the funding model

(led by STFC, UK)Investigate all aspects of the financial model for lifetime

costs of the SKAIssues: phasing of SKA and ELTs

what constitutes a “mature” project? post-PrepSKA funding

how to value in-kind contributions pre-construction

Investigate options for loan from European Investment Bank and other similar bodies to provide a smooth funding profile

WP7 – Implementation plan (led by Co-ordinator)Investigate socio-economic and knowledge impact of the

SKAIntegrate output of all other partners to produce a

detailed, costed design for Phase 1 of the SKA and an implementation plan for the full SKA.

2008 7 responses (ASTRON, CSIRO, INAF, JPL,

Audit Committee to make recommendations to SSEC by February 2009

Issues How is the in-kind contributions register

going to be used by the Funding Agencies?

What is the “value” to the international SKA program of the submissions to the in-kind register?

Should we only consider contributions in the PrepSKA era?and/or

Only those contributions that made mention of the SKA in the original proposals?
