Let us benchmark other lampost

Situation background:

1.  Right after November 1, 2012, I requested for plan and proposal for the construction of Lamp Post to accommodate metal halide and it called for few posts that are omni directional and equipped with ladder and cage for access by electrician.  I guess the height was for 30 to 40 ft and called for massive design and structure.

2.  However:

      1.  The proposal slept in many desk for 11 months;   the engineer gave it the cmo for budget, the cmo and the controller did not attend to this;  and the project engineer could only point to these causes why the project was not started at all

     2.  The new technology called for LED with lower intensity and lumens

     3. The redesign was presented sometime in September and much lower post were needed only 20 ft;  I requested for a redesign for 20 ft post.

3.  Then all of sudden Brenn requested for the approval of a lamp post project that was 20 ft, had horizontal bars;  however the cost and the design LOOKED AS OVER OR EXCESSIVE.

i  LOOKED AT OTHER MALLS WITH 20 FT LAMP POSTS AND TRIED TO COMPARE THIS WITH OUR DESIGN:

      Lamp post:     20 ft 6 inches with cage and horizontal bar schedule?

      Pedestal:    1.5 meter  1.5 meter hgt from ground 2.2 meter

                         base plate 14 inches x 14 inches (thk unknown with 8 studs no gusset, 

      The design was apparently applicable to  a much higher lamp post that needs access facility and safety for servicing the lamp post (replacing bulbs)  However we have much lower post (20ft) that can be accessed by stairs and does not need additional accessories.

The following pictures reflect more economical and more practical design:

They looked like:

20 ft tall, 5 inches post, with gusset support, (4 to 6 inches - 3/8,  pedestal of say 30 cm visible or more, 4 anchor bolts (maybe 20 to 22 mm)  6 x 6 baseplate..  Let us cost down and make our design more efficient?

                                       At Megamall, the pedestal looks like 30 to 40 cm

                                     

                                       Baseplate at Megmall;   6 x 6 inches, 1/2 thk, 4 bolts

                                          Lamp post at starmall crossing, 20 ft maybe 5 inches

                                                   The lamp attachment

                                          8 inches x 8 inches base plate with 4 bolts;  no Gusset

                                          Attachment points for lamps at the end of the post;  details

                                                  At Jollibee Turbina:

                                  8 inch by 8 inch base plate, maybe 1/2, with 4 bolts, only 20 mm;   galvanized

                                              Other view of base plate

Bottom view of the details of lamp attachment (reverse of base plate;  with angle bar and drilled holes for ready installation/attachment)

                                               Another efficient base plate design

                                           20 fr tall lamp post with thin maybe 4 inches posts.
