inaccessible for cleanout, inspecting and placement of concrete.
Re-use of fonns will be pennitted, but only to the extent that the produced surfaces are as specified.
Fonn oil shall be applied to wood and metal fOlm surfaces prior to placement of reinforcement.
Fonns shall be thoroughly tight to prevent leakage of concrete. They shall be properly braced or tied together so as to maintain the desired position and shape during and after placing concrete. Provide positive means of adjustments capable of taking up settlement during concreting operation.
Properly place and secure all inserts, conduits, sleeves, embedded plates, bolts, miscellaneous metals and other fastening devices before placing concrete.
Unless otherwise called for, fonn chamfers at corners of exposed concrete with inch by % ineh strips accurately formed to produce uniform straight lines and tight edge joints.
Drill forms to suit dowels used to prevent leakage of concrete mortar around the holes. Do not splinter fOlms by driving dowels through improperly prepared holes. Threaded screw reinforcing splices at form faces may be used to avoid holes in forms (LENTON or equal). Install per manufacturer's instmctions.
Provide sharp, clean corners at intersecting planes, without visible edges or offsets. Back joints with extra studs or girts to maintain tme, square intersections.
Use extra studs, walers and bracing to prevent objectionable bowing of forms between studs to avoid bowed appearance in concrete. Do not use narrow strips of fOlm matelials, which will produce bow.
Assemble fonns so they may be readily removed without damage to exposed concrete surfaces.
REMOVAL OF FORMS
Review fOlms in a manner to ensure complete safety of the stmcture. Do not remove until stmctural members have acquired sufficient strength to safely support their own weight, plus constmction loads.
