(2) If scrap materials are to be retained by the contractor, a cost credit for the amount of scrap should
be received by the government. This cost credit should equal the fair scrap value less a small amount for
handling and transporting the material.
8. CONSTRUCTION AND ON-SITE INSPECTION.
a. Quality on-site inspection, during all remedial work, is an essential element for a successful track
rehabilitation. While such inspection is certainly no substitute for professionally done track work, it is an
effective means of assuring that all work is, in fact, performed according to the contract specifications.
b. On-site inspection during rehabilitation work can discover deficiencies or errors that would be difficult
to detect during a completion inspection, or expensive to correct if discovered only after work was
completed. Such items include:
(1) Was all excess vegetation removed before ballast was unloaded?
(2) Where track in crossings was to be completely rebuilt, was the old ballast completely stripped?
Was the subgrade properly graded? Was drainage fabric installed? Were all new ties installed?
(3) Did the track actually receive a full 3-in. raise (or were the rough spots just smoothed out)?
(4) Was every tie tamped/? Did each tie get two insertions by the tamper? Did joint ties (on the joint
side only) get an additional (third) insertion? Likewise, correcting the following items after the work has
been done would be difficult, at best:
(a) Tie and ballast material not as specified in the contract.
(b) Old, fouled ballast in shoulders not fully plowed out before new ballast was unloaded.
(c) Culvert improperly positioned, or site not graded properly before culvert was installed.
(d) Defective concrete or insufficient reinforcing in loading ramp.
c. It is recommended that the work be inspected by the same people who did the design and
