1. A reticulated driven micropile footing method comprising:
(i) providing a reticulated driven micropile footing system comprising:
(a) a one-piece pile cap having a flat top surface and a continuous peripheral sidewall descending downward to form an open shell;
(b) embossing formed into said flat top surface, adapted to strengthen said one-piece pile cap against distortion;
(c) at least one mount hole extending through said one-piece pile cap, adapted to provide for mounting to said one-piece pile cap;
(d) a medial opening in said one-piece pile cap, wherein said embossing being formed adjacent said medial opening;
(e) at least three micropiles;
(f) at least three angled guides formed in the sidewall of said one-piece pile cap and extending outwardly therefrom, said guides being adapted to guide said micropiles at a defined angle relative to the top surface of said one-piece pile cap;
(g) at least three pile openings through the top surface of said one-piece pile cap, each through a said angled guide, adapted to allow angled insertion of a said micropile; and
(h) upper set holes in said one-piece pile cap near said pile openings, adapted to facilitate secure fastening of said one-piece pile cap to said micropiles;
(ii) analyzing soil conditions and load-bearing requirements for footings;
(iii) determining number and length of said micropiles for each said one-piece pile cap sufficient to meet said load-bearing requirements under said soil conditions;
(iv) placing said one-piece pile cap;
(v) placing said micropiles through said pile openings and said angle guides;
(vi) driving said micropiles through said pile openings at the angle set by said angle guides;
(vii) fastening said micropiles to said one-piece pile cap through said upper set holes; and
(viii) attaching structural pieces to said one-piece pile cap through said mount holes.
