CONTRACTOR QUESTIONS and RESPONSES
Question: L1.2 calls for slip joint spacing at bike rack to be 24”oc and Detail
5/L2.1 indicates 12” oc. UON. Verify the plan view spacing at 24” is correct.
Answer: The notes in question are all correct – 12” is the typical spacing for the slip joints and the instances you list are two “otherwise noted” instances.
Question: Detail 5/L2.1 calls for epoxy of the slip joint dowels into new concrete slab. Can this note be deleted? If not, please provide sequencing or procedure for this process.
Answer: Revise this note as follows: Drill and epoxy in existing concrete #4 x
18 ” undeformed epoxy coated rebar @ 12” o.c. unless otherwise noted. Embed of 6”.
Question: Please provide specification for concrete.
Answer: See General Note #5 on Sheet C1.0. The city specifications for all civil work can be found at: http://www.springsgov.com/units/cityeng/specmanual/COS_SpecManua l.pdf
Question: The current details 1 & 2 on L2.1 call for welded connections.
Would it be possible to change the connections to bolted since the two pieces are powder coated different colors?
Answer: The details cited do not say welded connections, but we do want the plate steel sign welded to the posts. The sign and posts finish are not powder coated as noted on t he details – change that to a two-part polyurethane paint with UV extenders and an exterior

DETAIL catalyst – color duradonic. Signs are two-sided with fou r colors o f high performance vinyl: top portion background and seal on bottom are duadonic, top portion text is white; bottom portion background is beige and bottom text is russet brown.
Question: Please provide rebar requirements for Detail 2/E1.0.
Answer: See the attached revised detail.
Question: Detail 2/C1.1 – Is the riprap swale to consist of loose rock or grouted rock? If grouted, what are the specifications of the grout? If not, will filter fabric be required below the rock?
Answer: The swale shall be loose rock, without grout and without filter fabric.
Question: There appears to be an existing area drain inlet south of the new stairs at existing riprap. Assuming it is to remain and not be replaced; will there be an inlet required north of the stairs in the newly configured riprap area? If so, please provide specifications.

1.9
Answer: No new inlet north of the new stairs is required – there is an existing 12” PVC pipe which directs the drainage west of the stairs to the existing inlet.
Question: REF: Details 9 & 7 on L2.0 – It would be a good idea to add #3 ties around the bottom four #4 bars on the same spacing as the vertical bars. This would give support to both the vertical and horizontal bars. Otherwise it will be difficult to suspend the bars or maintain minimum clear spacing requirements.
Answer: Yes, use ties necessary to keep the reinforcing indicated in place.
Question: REF: Details 9/L2.0 – What is meant by the 2”-5” TYP dimension shown for the sandstone veneer? Is the grout joint 2” with a 5’ sandstone veneer?
Answer: One supplier’s stone is specified as the “Basis of Design”. The thickness of this stone, and a possible equal, may vary between 1” and 4” – thus the dimension of 2”-5” for the stone ledge. The difference between these is the 1” required for grout behind the stone veneer.
