34 Specs

34.01 35 26 para 3.1.3

Spec 01 35 26 para 3.1.3 calls out Contract documents identify materials such as PCB, lead paint, and friable and non-friable asbestos and other OSHA regulated chemicals; however, no such callouts have been found. Please provide a hazardous materials survey or clarify if any hazardous materials are expected to be encountered.

Project Management

SEE ATTACHED Asbestos and Lead-Based Paint Testing Report for Existing Building 958.

4.0 Conclusions and Recommendations

The asbestos and lead-based paint assessment conducted on Building 958 located on Alabama Road at MCJNGB in Hopkins, South Carolina did not identify the presence of asbestos-containing materials or lead-based paint. If additional suspect ACMs not included in this report are discovered and will be disturbed by the renovation/demolition activities, bulk samples must be collected by a licensed asbestos inspector and analyzed for asbestos content, prior to disturbance of the suspect material(s).

SCDHEC requires a 10-working day written notification including submittal of this asbestos assessment report prior to building demolition. This report should be provided to contractors and design entities associated with the building demolition to ensure compliance with SCDHEC requirements for building demolitions. The installation ENV will need to know of any Haz waste found, stored or disposed of “PRIOR” to disposal and with manifest coordination “PRIOR” to disposal

35 Specs

Answer

53 Specs 08 71 00

Please clarify this perceived incongruity. The redacted sole source for cores and locksets requires Best brand, however from vol. I spec.

page. 661, spec. 08 71 00-14 it states for example, “FSIC Core 23-030 X “C” Keyway to match existing base system”. It does not reflect the Best sole source, instead it asks to match existing. Please clarify the cores and locksets, as there is no existing keyways to match. It is new construction.

169CES /

Architectural

The standard for McEntire JNGB is Best brand lock hardware with CORMAX SFIC (small format interchangeable core) utilizing 45H heavy duty mortise lock or 9K heavy duty cylindrical locks as specified

54 Specs 08 71 00

Vol. I spec. page 661, spec. 08 71 00-14 lists the core descriptions as, “FSIC Core”. FSIC means “Large Format” such as a Schlage brand.

However, the sole source Best core and lockset is an SFIC, “Small Format”. Therefore, it seems, the spec. Hardware schedule and the redacted Sole Source for the hardware are inconsistent. Please clarify the core and locksets for the openings.

63 Dwgs

For the building to be demolished as shown on C101 of plans, is there a hazardous material survey available for the building, OR if there is a hazardous material survey can the Govt. please provide the survey so we know what if anything needs remediated or abated, such as lead paint or ACM, asbestos containing material?

Project Management

Yes. See Response to Item 34 (above).

64 Dwgs C201 & C104

Sheet C201 notes the drain inlets and storm sewer piping at the mechanical yard as part of OLI #6. However the description of OLI #6 on the cover sheet does not mention storm drainage and sheet C104 shows the storm drainage at the mechanical yard as base bid.

Please clarify if the storm drainage for the mechanical yard should be included in the base bid or OLI #6.

Civil

OLI #6 shall include the drain inlets and storm sewer piping at the mechanical yard.

65 Dwgs G001

The descriptions for OLI #5 and OLI #10 both mention “curb cuts” as part of the scope of the option. The plans do not show any kind of curb work (cut/removal or new) associated with these options.

Please verify no curb cuts are required for OLI #5 and OLI #10. If curb cuts are required please provide plans that show the extent/requirements.

Project Management /
