RIGID PIPE PROOF TESTING UNDER EXCESS OVERFILLS WITH VARYING BACKFILL PARAMETERS: SECTION IX: ANALYSIS OF COSTS

An analysis is made of costs, based on bid item prices of ten zones of the dummy culvert and one zone in the functional, prestressed concrete pipe culvert at Cross Canyon. Cost per liner foot (meter) were as follows in order of economy: (1) Zone 2: $152.08 ($498.81); (2) Zone 4: $163.42 ($536.02); (3) Zone 1: $164.88 ($540.79); (4) Zone 3: $168.29 ($551.99); (5) Zone 9: $171.75 ($563.35); (6) Zone 5: $173.42 ($568.82); (7) Zone 8: $184.44 ($604.95); (8) Zone 6: $188.42 (618.02); (9) Zone 10: $193.01 ($633.07); 10) Zone 7: $209.28 ($686.43); (11) Zone 11: $443.16 ($1617.56). Zones 1 (steel struts), 2 (timber struts) and 3 (cement-treated bedding) were economical but are not recommended for reasons discussed in Section I. Zones 4,5,6 and 7 (variable strength) ranked economically in the same order as their strengths. Zones 9, 8 and 10 (low modulus inclusions) ranked in economy as they did structurally. Zone 11 (the prestressed pipe), if the same diameter, would have cost $321 per linear foot more than Zone 9, indicating a potential saving of $339,000 on this project alone. (FHWA)
