Specification: MIFAB Series T1400 6” wide pre-sloped trench drain system. Polypropylene drain body with integral top frame and 1/4" per section bottom slope, anchor flange with slotted tabs every 10” for rebar tie down and leveling, grate lockdown assembly, body support legs, interlocking ends, and radiused bottom. Standard with ANSI rated “Special Duty” lacquered ductile iron grates with a safe live load of over 10,000 lbs. (Note: Specify ductile iron frames for forklift applications.)
Function: Used in airports, car washes, malls and plazas, golf courses, factories, and any other facilities that require large areas of surface drainage. Chemical resistant polypropylene material provides for long life. V configuration channel design ensures maximum flow of water. Polypropylene support board prevents debris from entering trench body during construction.
Temporary trenches were also built. When a major attack was planned, assembly trenches would be dug near the front trench. These were used to provide a sheltered place for the waves of attacking troops who would follow the first waves leaving from the front trench. "Saps" were temporary, unmanned, often dead-end utility trenches dug out into no-man's land. They fulfilled a variety of purposes, such as connecting the front trench to a listening post close to the enemy wire or providing an advance "jumping-off" line for a surprise attack. When one side's front line bulged towards the opposition, a salient was formed. The concave trench line facing the salient was called a "re-entrant." Large salients were perilous for their occupants because they could be assailed from three sides.
Unlike sites which blend pricing from dissimilar jobs, homewyse estimates are based on the Unit Cost method. This method uses job specific detail for superior pricing accuracy and transparency - and has become an industry standard through publications and guidance of leading trade associations, including:
PHCCA , the NKBA , the NECA , the AIA , and the ASPE .
Cost to Dig a Trench - Notes and General Information These estimates are for BASIC work performed in serviceable conditions by qualified trade professionals using MID GRADE materials. Work not mentioned on this page and/or work using master craftsman, premium materials and project supervision will result in HIGHER COSTS!
