Questions and Answers for Solicitation W25G1V21R0020 Supply and Install of a 7-1/2 Ton Bridge Crane at Tobyhanna Army Depot

Q1: Is there an existing crane runway

A1: There is no existing bridge crane in the area.

Q2: What is the size and psi of the foundations?

A2: The foundation is 4000 psi.

Q3: Item 8 of statement of work states:

‘It shall be the contractor’s responsibility to install and connect all the electrical controls and utilities to place the crane in service. Source of power shall be from the electrical substation in the Southeast corner of the bay.’

How far is the electrical substation and what is our responsibility as far as this goes?

More detail on scope of requirements please such as TYAD electrical specifications/requirements and distances etc.

We have no idea currently of how to bid getting power from the substation, for example is power currently to a disconnect or distribution board external to the substation and we have to get power from that?

A3: There is a 12' w x 16'h cargo door entrance into the bay.

Refer to drawing, electrical substation is located in the Southwest corner of the 200' x 200' bay where the crane is being installed.

The CAD drawing shows the substation in the corner of the bay. Whoever installs the crane is going to have to have an electrician or hire an electrician to electrically connect the crane.

Q4: Please let us have the cad drawing of the foundation layout.

A4: The PDF drawing has been uploaded, if you need a dwg file email me.

Q5: Is there an existing crane runway if so:

1. What is the size/type of the existing crane Runway rail?

2. What headroom is there (top of crane rail to nearest roof obstruction)?

3. What is the floor to top of runway rail dimension?

4. What lifting capacity/weight/wheel loadings was the crane runway designed to?

5. What access is there into the site/building as we are quoting site unseen, is there a roll up door/truck access into the fabrication area?

A5: There is no bridge crane, runway, or any part of a crane structure in place in Bldg.

3-1. An all new crane and structure are required.

There is not an existing bridge crane or railway in place.

There is no runway in place.

There is no bridge crane, runway or any part of a bridge crane structure in place in Bldg.

3-1.

There is direct access into the bay though a 12' x 16' cargo door. While fossil fuel vehicles are not permitted in the bay without prearranged permission a wheeled vehicle such as a forklift can be driven up a ramp and straight into the building. There is not a dock delivery point on the bay (200' x 200' portion of the building).

Q6: If there is no crane runway then we need to know, again the Bid only calls for a 7,5t bridge crane it does not mention that you require a crane runway. Please clarify.

A6: There is no bridge crane, runway, or any part of a crane structure in place in Bldg.

3-1. An all new crane and structure are required.

Q7: The CAD drawing you sent does not show any substation despite your answer saying it does, furthermore you have given no information as to what is needed, simply saying we must hire an electrician to electrically connect is insufficient, it would all be guesswork as to what is required and could cost from $1000 to $50k... More detail is required as to what you require.

A7: As already identified, the substation is located in the Southwest corner of a 200' x 200' bay. There is not an existing electrical disconnect installed for the crane because specific electrical requirements of the crane being proposed is unknown. Contractor shall be responsible for connecting to the substation and installing the necessary electrical service to include the electrical disconnect, conduit and conductor from the substation to the crane.

Q8: I am looking at the documents for the above project and the drawing’s dimensions are too fuzzy to make out- specifically I’m looking for the column spacing on the runway.

Also, the specified minimum hook height of the hoist is 18’6”, should this be used to determine the height of the runway columns?

A8: The drawing is clear, try increasing the size. I can also supply a PDF version, which you will also have to increase the size to see dimensions.

Runway column height is certainly a part of the how the hook height shall be accomplished but it is up to the vendor to determine the height and clearances required to accomplish the identified 18'-6" hook height, taking into account such factors as the ceiling and superstructure height and the bridge dimensions and hoist dimension.

Just for clarification because it is not labeled on the drawing, the enclosed are in the Southwest corner of the bay in the drawing is the substation. The enclosure is simply chain link fence with a double swing gate for access.

Q9: Is this an existing building, correct?

A9: This is an existing building.

Q10: Drawing shows specific steel columns but no description, are they present or simply shown to describe required locations?

A10: Structural building columns are in place but columns identified on CL Column & Footing lines are for reference and location related to the existing footings.

Q11: Is temporary partition wall present?

A11: No, temporary partition wall has been removed this is a reference that was left behind from when this drawing was recently used for bay renovation purposes.

Q12: Foundation descriptive notes reference a foundation detail being shown but is not present, is this detail available?

A12: A PDF has been uploaded. If you need a dwg file, email me.
