15. Please clarify if the contractor is not required to provide any material testing, quality control, or inspections for the project?

22. Plan sheet 001C205 note 15 references detail E (001C100) for details regarding a

Rip Rap channel, however that detail is not on that sheet or elsewhere in the project plans. Can you please provide that detail?

See Detail E below.

23. For the electrical and fiber conduit, would directional drilling be an acceptable method of installation in some or all areas?

Installation of electrical and fiber conduit shall be per the requirements included in Spec Section 31 23 33. See Item 3.2.D for reference.

24. For the handrail, is 2” pipe for the railing or 1.5” required?

The minimum nominal diameter is 1.5”, the maximum nominal diameter is 2”.

Size, spacing, etc. within these limits is determined according to the loading and geometric requirements of the building code as illustrated in the calculations to be submitted per the specifications.

25. For the handrail, the posts are called out to be sch. 80 of the same size as above.

The OD will be slightly larger than the top rail and mid rail. Does that matter?

Outside diameter would remain constant between Sch. 40 and Sch. 80 of the same nominal pipe size. If different nominal pipe sizes are used for handrail and posts, connection details and design should be considered in the shop drawings and calculations submittals per the specifications.

26. For the handrail, can you confirm that the railing drawings on C104 and C105 are drawn to scale of 1” =10’? When scaled roughly 68’ total for both sides. But the drawings show a post spacing of 3’ and when added up with the post spacing it’s more like 90 feet total.

The contract plans are drawn to scale but are not intended to reflect the final configuration of the handrail. The minimum length of handrail is determined by the locations along the walls where the exposed wall height is a maximum of 4ft. The 3ft post spacing shown on Sheet 000C105 is a maximum and post placement should consider exposed wall height, clearance to wall joints, and angles in the wall alignment. These considerations should be reflected in the shop drawings per the specifications.

27. For the base plate thickness, would 1/4" be acceptable?

Specifications require a minimum of 3/8”x6”x6” plate for mounting to concrete but must be designed to resist building code design loads and accommodate the designed anchorage system.
