<br />columns, and similar parts of the work, may be removed after cumulatively curing at
<br />not less than 50 F (10 C) for 24 hours after placing concrete, provided concrete is
<br />sufficiently hard that no damage will occur by form removal operations, and
<br />provided that curing and protection operations are continued.
<br />3.17.2 Immediately after forms have been removed, all exposed tie wires and stapled ends
<br />shall be removed from the concrete surfaces to be exposed-, cut ties flush with
<br />finished surfaces of all other concrete. rub smooth or cut off fins and rough places,
<br />remove all loose concrete and fill honeycombed surfaces-, stone pockets-, and other

<br />been made by Architect and permission given. Before Publix makes the next
<br />inspection for pouring concrete, all previously poured concrete must be pointed up.
<br />3.18. Reuse of Forms
<br />3.18.1 Clean and repair surfaces of forms to be reused in work. Split, frayed, delaminated,
<br />or other -wise damaged form facing material will not be acceptable for exposed
<br />surfaces. Apply new form coating compound as specified for new form -work.
<br />3.18.2 When forms are extended for successive concrete placement, thoroughly clean
<br />surfaces, remove fins and laitance, and tighten forms to closejoints. Align and
<br />secure joints to avoid offsets. Do not use "patched" forms for exposed concrete
<br />surfaces.

<br />3.6.3.3 For concrete and solid masonry anchorage, use drilled -in expansion shield
<br />and either concealed hanger bolt or exposed lag bolt, as applicable.
<br />3.6.3.4 For hollow masonry anchorage, use toggle bolts with square heads.
<br />3.6.3.5 For wood stud partitions, use lag bolts set into wood backing between
<br />studs. Coordinate with stud installation to accurately locate backing
<br />members.
<br />3.6.3.6 For steel -framed gypsum board assemblies, fasten brackets directly to
<br />steel framing or concealed anchors using self -tapping screws of size and
<br />type required to support structural loads.
<br />3.7. Adjusting And Cleaning
<br />3.7.1 Clean the following metals by washing thoroughly with clean water and soap,
