WORK PERFORMED SO FAR • DC Transmission from D to C Site was proposed in November 2000 • The idea was developed further in several reviews in early 2001. Facilities Department (Carl Potensky was advised of the developments – this was to enable to perform site studies for positioning the towers • When there was a consensus to the approach , under Basic Order Agreement S-04236-F, Job Order # 3 (Title 1) was issued TO Burns through FACILITIES DEPT in December 2001. This was to provide an estimate for the task • Burns provided their input of estimate on January 11 2002 through Henry Carnevale. • Facilities department was studying the route in 2002/2003 • Burns were asked to perform the design work and under BOA issued Title 2 services through Facilities Department on December 12 2003. Facilities Dept gave input to Burns for location of Piers. • Burns submitted their PDR version ( also surveyed) in early Feb.2004; ( PDR held on Feb.14 2004) • FacilitIes Dept. conducted GPR on proposed locations of Piers in March/April 2004 Raki Slide 4
