The actual construction cost is $35,687.80 below the original contract
amount. The savings is attributable to using a pavement engineering fabric
between the old pavement and the new overlay known as a .SAMI (Stress Absorbing
Membrane Interlayment). The purpose of the SAMI is to provide a waterproof
membrane/barrier and to retard the growth of reflective cracking. Prior to
bidding, an estimate was made of the amount of old pavement that would have to
be removed and replaced. At time of construction, a field survey was made by
engineering and maintenance personnel to determine the exact areas of pavement
that had to be removed giving consideration that the use of a SAMI -vould
eliminate the need to remove pavement which only showed minor cracking.
The use of a SAMI reduced the amount of pavement to be removed by 8000 square
feet and pavement replacement by 700 tons of asphalt concrete.
FISCAL IMPACT: None.
