RESPONSE: Rooms 002, 003, 004, 102

4. What all needs to be painted? The Finish schedule outlines painting the vestibules on each floor.

Patching is also required for any new utility installs where not indicated to receive full depth pavement.

13. Please clarify, where is the ECM – NAG S-75 to be placed?

RESPONSE: Erosion control blankets must be installed at all locations to receive lime, fertilizer and seed.

14. The E&S Drawings show Silt Fence and Super Silt Fence; however, these types of silt fence are not typically used anymore. Will Silt Fence be acceptable? a. If not, must Compost Silt Sock be used? If so, what size(s)?

RESPONSE: The drawings in the construction set were approved by the stormwater authority. Any alternates must be approved by the stormwater authority and the VAMC prior to installation.

15. Drawing S-3 shows the entry road to the site marked, “repaving included as alternate bid”. All of the alternates for this project are deducts. Is this repaving item to be included in the base bid?

Should the bid form include a deduct alternate for not repaving the entry road?

RESPONSE: The drawings in the construction set were approved by the stormwater authority. Any alternates must be approved by the stormwater authority and the VAMC prior to installation.

Drawing E- 100 shows a new parking lot with six light poles where the contractor laydown area was, not on S-3 or S-6. Please confirm if we are to include this lot with asphalt and concrete curbs in our bid?

RESPONSE: The parking lot has been deleted from the project. Sketch SKE-1 is attached reflecting this change to the electrical site plan E100. Contractor must construct the laydown area to support job trailer, contractor parking and material storage.

17. Drawing A 6.2 is noted “ Signage Schedule”, however the schedule is incomplete, without quantities for each sign required and no locations are indicated on any floor plans on any SA drawings for any interior signs. The only signs shown are the parking entry/ exit signs (4/A501) on the exterior elevations A-201 & A-202. Please provide a drawing locating the signs and quantities.

Placement of the fill and construction the new parking lot to the North of Parking Lot B.”

RESPONSE: The suitable excavated soil from the parking garage excavation may be used as compacted fill for the New Parking Lot to be constructed. This may reduce the need of imported and/or exported soil if the soil from the excavation is suitable for placement under the new parking lot.

37. Question part 1 to above reference: Please clarify that the earth retention system for the garage building is to be in phase 1?

RESPONSE: We are not to dictate means and methods for construction. A schedule / plan for the earth retention system during and after the excavation should be provided as part of the proposal. An engineered earth retention system shall be provided by the Contractor for review by the Engineer prior to start of construction.

Question part 2 to above reference: Please clarify if the excavation spoils from the garage are permitted to be used in the construction of the parking lot and detention basin?

RESPONSE: The suitable excavated soil from the parking garage excavation may be used as compacted fill for the New Parking Lot to be constructed. This may reduce the need of imported and/or exported soil if the soil from the excavation is suitable for placement under the new parking lot.

38. Reference the Drilled Caissons specification Section 316326, paragraph 1.4 A and 1.8 G, reference a caisson load test/pile load test. Can you specify what type of load test, design capacity of test, and number of tests are required?

41. Please clarify location Where the storm and sanitary lines are to tie into (i.e. elevator sump sanitary line is bidder to only include to say just 5’ outside the building and from there connection will be “by others”?)

RESPONSE: Sanitary discharge shall connect to nearest existing sanitary main or manhole. GC shall coordinate scopes of subcontractors. Assume a minimum of 100’ of underground piping will be required.

42. Reference drawing P-FP101 there is reference on drawing “to new underground storm water holding tank, coordinate onsite connection with tank installer” ; question: please clarify if storm water holding tank is part of this project and if to be included or supplied “by others to be determined yet” and if coordination only is required?

RESPONSE: Holding tank is not being provided. GC to coordinate extent of storm piping between subcontractors; refer to civil drawings.

43. Reference Dwg S104 & SA401, there are posts “small rectangles shown outside the building perimeter at location of the canopy, & what I believe to be, canopy foundations. Are these small rectangles as referenced on the drawing the locations for the canopy foundations and if so are they to be installed per detail 14/S201?

RESPONSE: Correct, canopy support posts are shown. Provide post foundations per Det.
