34. Q: Are the use of explosives permissible on this site for rock excavation?

A: Explosives shall not be utilized per EM385-1-1, Section 29.

35. Q: Section 31 60 00 for foundation preparation discusses preparation of the bedrock surface and use of dental mortar. Is it the designer's intention to excavate all existing overburden to the bedrock, perform "preliminary cleanup,” and dental mortar prior to placement of aggregate base course beneath the mat foundation of the building? If this is the case, will the Government consider the use of an allowance to compensate the Contractor for preliminary cleanup and dental mortar work directed by the COR since this is an unknown condition?

A: The preparation of the site was performed under a separate contract.

36. Q: The Government COR/QA at the Fish Barrier site currently utilizes offsite warehouse and office space for their personnel, but the drawings indicate that the Contractor should provide field trailer(s) for the Government. Please advise if the Contractor should include the cost of office space for the Government on this project.

A: The contractor shall provide costs for the field trailer per specification section 01 52 02 TEMPORARY CONSTRUCTION FACILITIES. The cost for the existing USACE offsite office/warehouse should not be included in those costs.

43. Q: In Amendment 0002, in response to an RFI it was stated that the contractor is responsible for setting grades on the ComEd electrical distribution manholes. Would the contractor then also be required to develop engineering drawings, i.e. Plan & Profiles for ComEd and Corps review/approval?

A: The construction of the ductbank shall be documented in the As-Built drawings provided by contractor per specification section 01 78 00 CLOSEOUT SUBMITTALS. In addition, the contractor will have to work with ComEd to obtain engineering approval and is responsible for providing all information ComEd will need to see before construction starts to verify the design meets their standards. ComEd standards require underground duct runs to have specific grade and cover requirements implying they will likely require detailed plans and profiles.

44. Q: Revised Drawing C-108 issued via Amendment 0002 shows what appears to be pavement striping where curb and gutter was shown previously. Please verify if this is correct or advise otherwise.

A: Correct. In Amendment 0002, the middle curbed island was removed and pavement striping was added.

45. Q: Revised Drawing C-107 issued via Amendment 0002 and RFI response #12 states the relocated fence is shown. It is unclear whether the fence has already been relocated or if relocation is part of this contract, please advise.

48. Q: What is the specification for acoustic ceilings and where does it apply?

A: There are no acoustic ceilings in this project. All the ceilings are constructed from steel studs and drywall.

49. Q: Column line 1 elevation / S-203 references further details for the elevated slabs, but does not specify the support walls. This is typical throughout sheets S-203 through S-207. Where is the information for the support walls?

A: See the CONCRETE WALL SCHEDULE on Sheet S-601 STRUCTURAL SCHEDULES for wall detail information.

50. Q: The foundation plan / S-101 show walls on the plan, that are not shown in the column line frame elevations. What is correct?

A: They are not considered part of the primary support frame. Please see the CONCRETE WALL SCHEDULE on Sheet S-601 STRUCTURAL SCHEDULES for wall detail information.

51. Q: Section 2 / S-304 does not specify the reinforcing for these stairs, or the landing slabs.

A: Per Amendment 0004, reinforcing notes have been added to Sheet S-304 STRUCTURAL SECTIONS SHEET 4 in Section 2- 207/304.

52. Q: Specification section 23 00 00 3.2.6 declares all ductwork to be continuously welded 1 ga. 304L or 316L in exposed areas. This job consists of mainly exposed duct, most of which is round. This will cost significantly more if this is the actual intent. The drawings have only the control room ductwork tagged as stainless steel and does not state it is to be welded.

A: By way of Amendment 0004, specification section 23 00 00 AIR SUPPLY, DISTRIBUTION, VENTILATION, AND EXHAUST SYSTEMS, para 3.2.6 has been revised by deleting the continuous welding requirement.

53. Q: Spec section 01 52 02 Temporary Construction Facilities paragraph 1.4.2 has been revised, but the revision is missing from the addendum. Can you please get the missing paragraph clarified, as this deals with the connection of the permanent power.

A: Specification section 01 52 02 TEMPORARY CONSTRUCTION FACILITIES has been provided in Amendment 0004.

54. Q: States there is not any furniture included in the contract. Note 2 on drawing T102 states to make furniture connections for Voice / Data connections; can we assume that this note can be disregarded?
