posts for 10’ high fence but a drawing detail shows a 4” OD terminal post. What is supposed to be installed?

Answer 1: See Item No. 2 Specifications Volume 2 of 2, Technical Provisions above. Question 2: Specifications Vol. 2 – Standard Technical Provisions – at the end of each

individual section, under this heading, there is a subsection, “Basis of Payment”. This subsection reads, “Payment will be made under:” and units to follow. Since the bid is one lump sum price, how are these unit prices in these sections going to be utilized?

Answer 2: See Special Provision SP-28. Question 3: Fence along east side of concrete pavement is to be 1’ off of pavement edge.

There is an underdrain shown along pavement edge that will interfere with the excavation of the fence post holes. The fence needs to be moved at least three feet further east so that fence post excavation does not get into pipe underdrain or stone backfill for same. The standard rat wall would have to be used at the moved fence location.

Answer 3: See Item No. 3 Plan Sheets – Base Bid above. Question 4: Can two widths of chain link fabric be overlapped to make 14’ fabric? Most

suppliers have a special set up charge for minimum quantities of special products. 14’ fabric is a non-standard product.

Answer 4: No, see Special Provision SP-19.



of 12 Question 5: The 4” OD hinge post for the 16’ swing gate is too small. The hinge post needs to

be at least 6 5/8” OD. The latch post can be 4” OD. Answer 5: See Item No. 3 Plan Sheets – Base Bid above. Question 6: Is the interior fence to be wire mesh partition type or chain link type? The drawing

detail calls for the mesh to be attached to channel frames with the frames being welded to the support structure. This more describes a modified wire mesh construction. Chain link type fence is not constructed with channel frames, etc. If it is to be chain link fence, can standard installation methods be used where the fabric would be stretched and secured to the support posts and rails? This is what the specifications call for.

Answer 6: Interior fence to be chain link type. Mesh is to be attached to support posts and

rails. There are channel frames required for wire mesh doors and high speed doors.

Question 7: Can ¾” diameter wedge type anchor bolts be used to secure post plates to floor

instead of the 5/8” diameter adhesive type anchors? The wedge type anchor bolt will provide for an immediate securing of the post to the floor rather than having to wait for the adhesive to set.

Answer 7: No, provide anchor as shown on drawings. Question 8: The drawing detail shows a galvanized plate welded to the post. Can the weld be

primed and painted with a zinc rich type product? Answer 8: No, plate and post to be galvanized in one piece. Question 9: Two drawing details show 9 gauge wire mesh and two other details show 6

gauge wire mesh. What is to be used? Answer 9: Interior fence to be 9 gauge wire mesh. Question 10: Why would a five year warranty be required on the interior fence and only a two

year warranty be required on the high speed rolling doors? Answer 10: Provide two year warranty for the interior fence and five year warranty for the

high speed rolling doors and the overhead coiling grills. Question 11: Cut section 7/S201 on page S100 doesn’t make sense. Is this correct reference?

If not, what area does 7/S201 refer to? Answer 11: Section cut 7/S201 shows how the grade beams frame into the footing. It is a

typical section at each footing.



of 12 Question 12: Will this project be subject to the new City of Indianapolis Pre-Permit Plan

Review? If so, is the GC responsible for review cost & permit cost? Answer 12: No. Not applicable. Question 13: At what elevation below grade are the strip footings? Answer 13: See plan sheets S100 Foundation Framing Plan and S200 Foundation Details. Question 14: Will a wall footing schedule be provided? Answer 14: A wall footing schedule is not needed. The section cuts show the wall footing to

be 2’-0” wide along with the required reinforcing. Question 15: Item #5 of the pre-bid meeting agenda allows for the maximum amount of work

that can be subcontracted to be 85%. Can this limit be extended to 90%? Answer 15: No, the limit will not be extended to 90%. Question 16: Spec. 03450 – Plant Precast Architectural Concrete, Section 1.04.A.6 – “Color

and finish to match adjacent AOC/EOC facility.”

A. Is there an arch. precast concrete mix design available from the AOC/EOC facility?

Answer 16A: No.

B. If not, could you provide a sample number from the 2nd Edition of the PCI Arch. Precast Color and Texture Selection guide to use as a basis for the bid?

Answer 16B: Field verify existing AOC/EOC facility. Precast shall be bid as:

White Cement 100% Limestone #11 Rock Limestone #13 Light Sand Blast

C. Is it the intent that local fine and coarse aggregates are acceptable?

Answer 16C: Precast to match existing AOC/EOC facility.

D. What is the finish required on the precast panels (sandblast [light, medium, or heavy], acid etched, or retarded finish)?

Answer 16D: Light sand blast.

E. What finish will be required on the form liner section of the precast panels? Answer 16E: See Technical Provision 03450, Paragraph 2.03.C.3.a. Interior Finishes.



of 12 Question 17: What are the exterior precast finish details? Answer 17: See Technical Provision 03450, Paragraph 2.03.C.3.b. Exterior Finishes. Question 18: What size precast mockup is required? Answer 18: Cast a 4 ft wide by 8 ft tall mockup of precast panels showing all items as called

for in the specifications and drawings. Question 19: Is Fabcon an acceptable manufacturer? Answer 19: Not at this time. Documentation has not been received that would support any

request to have Fabcon listed as an acceptable manufacturer. See General Provision 60-03.

Question 20: Specification Section 16211-2, Section 2.3. Will these meters tie into the same

BAS that all the previous Class 3000 meters have tied into at this jobsite? The spec is not specific on this detail. This required so the correct communication option is selected so proper pricing can be obtained.

Answer 20: See Item No. 3 Plan Sheets – Base Bid above. Question 21: Where do the step down in footing elevations occur at the East and West walls? Answer 21: The footing will step up starting at the northeast and northwest corners of the

building until the bottom of footing reaches -3’-0”. Question 22: Along the North wall there is three different wall section that reflect the walls

width from 8”, 10”, and 11” wide. Can the North wall all be the same width? Answer 22: The wall width may be uniform along the north wall. If the Contractor chooses to

construct a uniform thickness, the thickness shall be 11”. Question 23: On drawing S100 there are two section cuts, 3/S201 for two short interior stubs

walls. Another cut is 2/S201 in one area. Are the other areas that look similar that have no section cuts either 2/S201 or 3/S201?

Answer 23: The interior walls shall follow Section 2/S201, while the walls that connect to the

exterior wall shall follow 3/S201. There are two (2) locations on seven (7) walls which require 3/S201.

Question 24: Exterior truck ramp detail 6/S201 indicates rebar in the ramp slab while 4/S201

shows WWM. Which reinforcement is required in the ramp slabs? Answer 24: Exterior truck ramp shall be reinforced per detail 6/S201, #5 @ 12” E.W. Question 25: What is the thickness of the building slab on grade No. 53 stone fill? Answer 25: Building slab is 6” over 6” of INDOT 303 No. 53 aggregate.



of 12 Question 26: Soil stabilization is shown on the site details. Has this work be[en] done in the

early site release package? Is the cost of lime stabilization to be included in our bid?

Answer 26: Soil stabilization will not be performed by earthwork contractor (IAA Project No. I-

09-033-A). See Plan Sheet G107 – Site Work Schedule of Values, Line Item 36. Question 27: SP-10 indicates sub grade left +0.1’ for building pad and pavements. Are the

areas outside the building pad and pavements also left +0.1’, i.e. landscaped/seeded areas?

Answer 27: No. Question 28: What is the extent of the erosion control that has been installed by Early site
