Response to Bidder Questions:

1. C. L. Lewis: How are we supposed to address notes 6, 7, and 8 on C3.0? Most subs who bid the utility work would not have the appropriate time or probably authority to investigate these items before the bid date. If a value to perform these items needs to be included in the cost of the work, a more appropriate suggestion would be for an allowance to be included in the bid. Please advise. Response: bid the work regarding note 6 on C3.0 as ‘abandoned’. Bid the work regarding note 7 on C3.0 as ‘Investigate the existing service lateral, protect it during construction, replace in-kind if damaged, and relocate the meter behind the curb’. Bid the work regarding note 8 on C3.0 as shown with the information provided that this line is solely a storm sewer.

2. Creative Electrical Contractors Inc. 1) Drawing E101 says “provide 6-4” Ductbank with 3 sets of 4-500KCMIL + 1 #2 Ground”. Drawing E701, Note 2 says “run 4 sets of 4-350KCMIL 1 1-1/0 Ground in 6-4” Conduit Ductbank Minimum of 36” Below Grade to C/T Cabinet. Which is correct? Response: Drawing E101 is correct. Will revise drawing E701 to read the same conductor size as indicated on E101.

3. Creative Electrical Contractors Inc. 2) Drawing E301 shows the Dressing Room Areas. Does the Fixture Type FF Wrap around the Mirror on three sides at each individual station of the makeup counter or does it wrap around the mirror on three sides for the entire length of the makeup counter: Response: Fixture type FF is to run continuously across the top of the mirror.

4. Donald Lane, EMC Mechanical Services 1) General note #1 on sheet M501 states that all ductwork in the mechanical room will be lined with 2” liner. Will that include the fresh air and exhaust duct also and if so would that include the exhaust outside of the mechanical room as well? Response: Yes, all ductwork will require the 2” liner mentioned above.

5. Donald Lane, EMC Mechanical Services 2) General note #2 on sheet M301 states that all ductwork for the auditorium and lobby area from AHU-1 is to have 2” liner. Will the round duct shown on drawing M303 in the balcony area be lined as well? I can’t seem to find a spec on double wall duct anywhere. Response: Yes, all ductwork will require the 2” liner mentioned above.

6. Donald Lane, EMC Mechanical Services 3) Spec 23 31 13 – 11, section 3.9 Duct Schedule, paragraph B. 2 says that ducts connected to constant volume air handling units will be 3 inch wg. Typically low pressure is 1 and 2 inch wg and medium pressure would be 3 and 4 inch wg. Will this duct be considered to be medium pressure? Also paragraph B. 3 for ducts connected to variable volume air handling units shows a wg of 23 inch’s. Should this be 2 or 3 inch wg? Response: ductwork must be constructed in accordance with SMACNA duct construction standards for the pressure classification, seal class and leakage class listed in the specification. The “low pressure” and “medium pressure” distinctions are no longer recognized by SMACNA. The pressure class for supply ducts on VAV systems should be 3-inch wg.



7. Steve Tyree, Moores Electrical & Mechanical Construction: 1) Sheet E001, Light fixtures shown to be selected by architect. Are we to include an allowance for them or just labor to install them. Response: Please see attached revised fixture schedule.

8. Steve Tyree, Moores Electrical & Mechanical Construction: 2): Are we allowed to run surface raceway (wiremold) on existing walls not getting furred out? Response: Yes, surface raceway may be utilized in a workman like manner, only where existing walls are not furred out.

9. Ron McManamay, Gaston Wyatt Inc. Question After a careful review of the specifications, we have decided to propose quoting the Kingsview Single Hung by Hurd Windows on the project. These four specification section presented issues. Are these acceptable exceptions to the specifications: SECTION 085200 WOOD WINDOWS Section 1.5 B, 1.6 C – Hurd does not manufacture products with FSC certified lumber. Section 2.3 F – Currently, Hurd has not conducted STC testing on the Kingsview Single Hung. Hurd has achieved an STC 33 rating on the Premium Clad Double Hung utilizing the same glass as the Kingsview. The Kingsview is scheduled for STC testing in the near future and Hurd is confident the test report will confirm an STC rating exceeding the requirement of this project. Section 2.3 I, J – Hurd has not conducted Life Cycle and Durability tests on the Kingsview Single Hung SECTION 088000 GLAZING Section 2.2 F.5 – Insulating glass spacer will be mill finish aluminum in lieu or black anodized as specified Response: The University is open to alternative manufactures who can meet the performance requirements indicated in the specification. Provided windows need to meet or exceed the specified performance standards.

10. Creative Electrical Contractors, Inc: The lighting fixture schedule has a Type K fixture in it. This fixture does not appear on the drawings. is this fixture supposed to be used and if so what lengths? What circuits fed this fixture? How is the fixture supposed to be mounted? Response: The type K fixture is a low voltage LED fixture that comes in 18”, 36” and 54”. The fixture is to be provided in five 36” lengths mounted under the 15’5” transaction counter at the front reception desk. The lighting fixture is to be connected to the nearest 277v lighting branch circuit.

F. Do not bridge building expansion joints; cut and space edges of panels to match spacing of structural support elements.

G. Coordinate sheathing installation with installation of materials installed over sheathing so sheathing is not exposed to precipitation or left exposed at end of the workday when rain is forecast.

3.2 GYPSUM SHEATHING INSTALLATION

A. Comply with GA-253 and with manufacturer's written instructions.

1. Fasten gypsum sheathing to cold-formed metal framing with screws. 2. Install boards with a 3/8-inch gap where non-load-bearing construction

abuts structural elements. 3. Install boards with a 1/4-inch gap where they abut masonry or similar

materials that might retain moisture, to prevent wicking.

B. Apply fasteners so heads bear tightly against face of sheathing boards but do not cut into facing.



C. Horizontal Installation: Install sheathing with V-grooved edge down and tongue edge up. Interlock tongue with groove to bring long edges in contact with edges of adjacent boards without forcing. Abut ends of boards over centers of studs, and stagger end joints of adjacent boards not less than one stud spacing. Attach boards at perimeter and within field of board to each steel stud.

1. Space fasteners approximately 8 inches o.c. and set back a minimum of 3/8 inch from edges and ends of boards.

2. For sheathing under stucco cladding, boards may be initially tacked in place with screws if overlying self-furring metal lath is screw-attached through sheathing to studs immediately after sheathing is installed.

D. Vertical Installation: Install board vertical edges centered over studs. Abut ends and edges of each board with those of adjacent boards. Attach boards at perimeter and within field of board to each stud.

1. Space fasteners approximately 8 inches o.c. and set back a minimum of 3/8 inch from edges and ends of boards.
