CHAPTER II, SECTION 5 tion was misoriented by approximately 12 . Since the orientation was only for structural purposes and was not critical, the User approved the new orientation. Special instructions were issued to all party chiefs and this error was not repeated. CONSTRUCTION. Work was originally schedwed to commence on 1 August and to be completed by 15 February 1954. Actual work started on 28 July and was completed on 6 February. STATION 104 - RECORDING STATION SITE IRENE - USER: SANDIA GENERAL. This Station was added in March 1954 due to the rescheduling of the Test Program. The work involved consisted of reactivat ing IVY Recording Station 600 and connecting up to the 120 series Stations located on sites Gene, Helen and Irene. (Stations 120.24 thru 120.28). ENGINEERING. Field Engineering prepared drawings and tield sketches as required. CONSTRUCTION. Work was started on 19 April 1954 and was completed on 20 April. STATIONS 110.02 - 110.05 - ROCKET LAUNCHERS - SITES VARIOUS USER: NOL GENERAL. These Stations were located on sites Charlie. Dog, Uncle and Pearl and each Station consisted of two tvpe A-1 tents equipped with work henches and electrical outlets; these Stations were used for rocket trail photography. Five KW engine generators were provided for the power supply. ENGINEERING. One drawing was submitted on 22 July and was approved on 14 August. CONSTRUCTION. Starting dates varied from 7 September to 15 December 1953. Completion dates Varied from 20 January te 2 Fehruary 1954. STATIONS 120.01 - 120.299 - GROUND BAFFLES - SITES VARIOUS USER: SANDIA GENERAL. These Ground Baffle Stations were located on various islands of both atolls. Each Station consisted of a precast reinforced concrete cube which contained User’s equipment embedded inside the cube. This equipment recorded surface pressure versus time. The cubes measured 1’-6". Figure 2-93 shows Station 120.13 on site Sugar as 30° completed on 5 January 1954. Wher completed the top of the cube was flush with the finished grade. ENGINEERING. The criteria were received 11 May for Stations 120.01 thru 120.22. On 9 September, Station 120.23 was added. On 1 March 1954 Stations 120.24 thru 120.29 were added. Station 120.29 was later deleted. Minor detail plans were included with other Stations. Page 2-100 mee Figure 2-93. Station 120.13 - Typical of Series &0°, Completed CONSTRUCTION.

STATIONS 122.01 - 122.35 SELF RECORDING GAGES SITES VARIOUS - USER: BRL GENERAL. The work involved consisted of locating and embedding four 6 ” I. D. steel pipes in a two-foot square configuraiion. The pipes were embedded three feet into the ground and instruments were attached which recorded pressure versus distance. ENGINEERING. The original design criteria received on 30 April were for Stations 122.01 thru 122.27. On 9 July, Stations 122.01 thru 122.24 were deleted and Stations 122.28 thru 122.34 were added. Criteria of 2 Septemberre- located Station 124.08. On 5 October, Stations 122.16 and 122.17 were relocated. On 23 October, Stations 122.28 thru 122.35 were deleted. One drawing was started 16 June, submitted on 24 June and approved and released on 14 July. CONSTRUCTION. The schedule contemplated work to start on 10 January 1954 and to be completed on 5 February. Actual construction starting dates varied from 1 December to 18 January and completion dates varied from 8 January to 6 March 1954. STATIONS 123.01 - 123.07 - REEF GAGES SITE CHARLIE-DOG REEF - USER: BRL GENERAL. These Reef Gage Stations consisted of a 6” I. D. steel pipe embedded ten feet into the reef and projecting six inches above high water, to which were attached instruments which recorded pressure versus distance. ENGINEERING. The original criteria were re- ceived on 30 April 1953. On 29 June Stations
