Refer to Samet Corporation standard details and standards.
INITIAL
Familiarize self on where all surface site drainage is directed. In general, all site drainage
will be directed to underground storm drain systems which will carry it offsite. If there are
areas of the site drawings directly onto adjacent sites and/or if catch basins located in low
points would back storm water into a structure if the catch basin becomes blocked, bring
these facts to the architect’s attention.
Site was checked on ______________date for preexisting problems on site drainage.
Familiarize self on where all underground site drainage is directed; making sure that there
is no reverse flow in pipes. Review plans for possible conflicts between underground storm
drain pipes and other utility lines, especially other gravity flow pipes (sanitary sewer lines).
If possible conflicts, expose conflict before storm drain excavation is begun and have
surveyor verify that no vertical conflicts exist.
Review standards for catch basins and manholes (or junction boxes). Require submittal of
catalog cut be submitted to architect if structures are precast. Grates and structures have
been reviewed on _____________date by ______________
And all structures and grates meet all governing authorities for type, steps and blades per
there requirements. Not necessarily shown on drawings.
Verify elevations of tops and bottoms of drainage structures and flow limes of storm drain
pipes against layout survey stakes.
Review backfill standards for drainage structures and storm drain lines. Have soils engineer
test and certify backfill methods and compaction.
Familiarize self with types of storm drain pipes allowed. If ACP is allowed, special handling,
cutting and disposal requirements apply, as asbestos is considered a hazardous material.
Obtain manufacturer’s recommendations on jointing methods. Review bedding against
local codes and manufacturer’s recommendations. ________________bedding materials are
accepted on this site.
Review safety shoring requirements for excavations over 5 feet in depth.
Familiarize self with concrete mix and strength requirements. Collect delivery tags. Obtain
certificate of conformance to specifications. Take concrete slump tests and cylinders, if
required.
Ensure that an encroachment permit is obtained by the contractor, if required, for tying-in
site drainage storm drain lines into the jurisdiction’s main lines.
Inspect all storm drain lines for joint integrity that lines are true for slope and horizontal
alignment, and that bedding is proper prior to allowing contractor to backfill storm drain
lines and structures.
Curb inlet structures are the responsibility of _______________contractor for alignment and fit.
WORK/COMPLETION
Have subcontractor clean all catch basins and flush all storm drain lines prior to job
acceptance.
Review inside of all drainage structures for rock pockets and defects in workmanship. All
forms to be removed.
___________________contactor is responsible for making sure all structures are mortared in,
flares are cut and there are no obstructions prior to engineer sign off.
