14. Drawing, Page 54 CS502, Detail C3 Sawed Contraction Joint; Specifications Part 2 of 2

Section 32 13 13.06, Page 12, 3.4.7.1 Contraction Joints. On the drawing CS502, the Detail C3

Sawed Contraction Joint does not show any dowel bar. However, on specification section

3.4.7.1 Contraction Joints, it mentions “dowels in longitudinal and transverse contraction joints within the paving lane must be held securely.” Please confirm if the dowel bar will be provided on the contraction joints.

ANSWER: Dowel bars are required only for contraction joints for “odd shaped” slabs per Detail

“Provide precast concrete septic tanks risers, base sections, and tops conforming to ASTM

C1227 with Type II cement.

On the drawing CU504, the detail C4 and B4 clearly indicates that the septic tank wall is 8”

CMU wall with Reinforcement bars ½” @ 8” O.C.

Please clarify if the septic tank is precast concrete as per the specifications or a combination of precast concrete and CMU wall.

Please also confirm if the thickness of the concrete top slab of the septic tank is 8” or 6”.

ANSWER: Either precast concrete per the Specifications or CMU walls with cast-in-place concrete top and bottom slab are acceptable pending shop drawing submittal approval. The details on Drawing CU504 indicate CMU walls and cast-in-place top and bottom concrete slabs due to uncertainty on whether precast concrete septic tanks are available in Guam.

The top and bottom slabs indicated on Drawing CU504 must be cast-in-place due to tie-in of the rebar from the slabs to the CMU walls. The concrete top slab thickness must be 8-inches per the dimension indicated in Section C4/CU504. An amendment is forthcoming to include the following –

1) Remove the label indicating 6-inch top slab thickness in Section C4/CU504.

2) Provide notes on Drawing CU504 that indicate a precast concrete septic tank is an acceptable option.

3) Revise Specification Section 33 30 00 to add CMU wall option.
