ARMY TM 5-5420-212-10-1 MARINE CORPS TM 08676A-10/1-1 t. Final design During  the  preceding  design  process,  the  information  necessary  to  fill  in  the  blanks  below  would  have  been obtained. Fill in these figures in the pro-forma, at this point the design is considered complete. a. 2E + Bays b. LNCG Setting c. FRB Setting d. RRB Setting d. Bearing : NB FB e. Truck/Trailer Loads f. Manpower Required g. Time to Construct 3-15 DOUBLE STORY 2E + 1 thru 2E + 12 BAY DESIGN ON RESTRICTED SITES The design procedures for DS bridges (2E + 1 through 2E + 12 bay) on restricted sites is the same as for normal sites except that: a. The  length  of  the  launching  nose  is  increased  by  one  or  two  launching  nose  heavy  (LNH)  sections.  The decrease in the amount of R Distance required by increasing nose length can be seen in Table 3-23 below. b. During  construction,  the  number  of  times  that  the  bridge  is  boomed  will  be  increased,  and  the  distance  of each boom will be decreased. NOTE The distance for construction behind the FRB cannot be less than 9.1 m. If a vehicle and push bar are needed to boom a bridge, add 11.3 m to R Distance given. TABLE 3-23.
