The first six months of the report by Peter Dewdney), and the year saw a review of the preliminary top- Funding Agencies in the Netherlands, Italy level specifications for the SKA, the long and the UK are coordinating the “policy” awaited start of PrepSKA, the signing of work packages on options for governance, an agreement on RFI monitoring at the procurement and interaction with industry, candidate SKA sites, significant and funding respectively. With PrepSKA astronomical and engineering milestones and the supporting programs around the being reached by the ATA, LOFAR, world, the radio astronomy world has now Apertif, and EMBRACE, the start of SPDO formally set out on the path towards a recruitment of its senior engineers, and a proposal for SKA funding and most successful two-week series of construction. Much remains to be done, meetings in Perth. In addition, Peter but the global team is already at work!

Each of these appointments of SPDO engineering staff, and I am very is at a slightly different stage. One of them pleased with the experience and calibre of is working already at the University of the applicants for these positions. I have Manchester, and we expect most of them spent the balance my time understanding to be in place in Q3 or early Q4 of 2008. the scope of the PrepSKA programme, These people will in future be supported and planning for its execution. This will by additional engineering and technical take a while longer as we integrate the staff. We plan to introduce these people in rest of the team into the University of the next SKA newsletter, once all of the Manchester environment; define tasks at a appointments are made officially. more detailed level, and begin to work with the global network of partners. Engineering Activities I would like to take this opportunity to Apart from the recruitment drive, SPDO thank Peter Hall, my predecessor, for the efforts have concentrated on defining the many years of work as International scope of PrepSKA in an operational Project Engineer, realising that he was sense.
