PART 3    EXECUTION
3.1	EXAMINATION
A.	Do not begin installation until substrates have been properly prepared.
B.	If substrate preparation is the responsibility of another installer, notify Architect of unsatisfactory preparation before proceeding.
3.2	PREPARATION
A.	Clean surfaces thoroughly prior to installation.
B.	Prepare surfaces using the methods recommended by the manufacturer for achieving the best result for the substrate under the project conditions.
3.3	INSTALLATION
A.	Install in accordance with manufacturer's instructions and in proper relationship with adjacent construction.
B.	Commercial System Installation
1.	System Piece Marking:
a.	The system begins with an "end" section (one with a sealed end) which slopes towards a sump pit (collector pit). 
b.	Sloped sections are inserted to lengthen the drain to the required length.
c.	Each section has a coupling flange welded to it that is alphabetically coded to the depth of that end of section, i.e. a "B-C" section would start with a "B" flange, and over the course of the section it drops 1/2 inch (13 mm) and ends with a "C" flange. 
d.	The next connecting piece would start with a "C" flange and slope towards a "D" flange at the other end. 
e.	The flanges are bolted together in a four-bolt pattern.
2.	Rebar Tie-Ins:
a.	Alongside the trench, every 24 inches (610 mm), an 8 inches (203 mm) rebar section shall be welded, bent out 3 inches (76 mm) from the side of the trench. 
b.	Provide a secure tie into the rebar grid in the concrete. Pre-formed Rebar "stir-ups" are available from U-Drain
3.	Leveling Brackets:
a.	Leveling bracket mounts shall be welded into place, and leveling brackets are bolted onto the side of the trench to ensure proper leveling of the drain. 
b.	A rebar length, dependent on the thickness of the slab, shall be hammered into the ground through a slot in the bracket. The bracket's set screw shall be tightened to set the trench section at the proper height. 
c.	The brackets shall accommodate either #4 (13 mm) or #5 (16 mm) rebar.
3.4	PROTECTION
A.	Protect installed products until completion of project.
