MEMORANDUM FOR: Contractors

FROM: 109 MSG/MSC

SUBJECT: Addendum for Projects “Spill Control Dam – Catwalk and Baffle and Skimmer & Collection Manhole.”

The proposal response date will not be extended.

The following information was shared at the site visit conducted on August 2, 2011:

1) The catwalk must meet OSHA requirements per attached. Please note there are water safety requirements as well.

2) The grating of the catwalk should be galvanized steel.

3) The catwalk will need a step or multiple steps to access.

4) The “Existing Conditions” drawing is not available electronically; however a hard copy can be obtained through contracting.

5) Prior to initiating work, approvals may be necessary from FAA due to equipment usage within the flight path. Work may not begin until this approval process is complete.

Attached are two OSHA references that will aid in identifying what is needed for the lagoon’s catwalk. 29 CFR 1910.23(c) identifies the requirements of open sided floors, platforms and runways. The “catwalk” would be 4-5 feet above the surface of the water, this will require railings as specified in the attachment as well. 29 CFR 1926.106 identifies required safety equipment while working over water, if the level poses a hazard of drowning.

1910.23(c)

"Protection of open-sided floors, platforms, and runways."

1910.23(c)(1) Every open-sided floor or platform 4 feet or more above adjacent floor or ground level shall be guarded by a standard railing (or the equivalent as specified in paragraph (e)(3) of this section) on all open sides except where there is entrance to a ramp, stairway, or fixed ladder. The railing shall be provided with a toeboard wherever, beneath the open sides, 1910.23(c)(1)(i) Persons can pass, 1910.23(c)(1)(ii) There is moving machinery, or 1910.23(c)(1)(iii) There is equipment with which falling materials could create a hazard.

1910.23(c)(2) Every runway shall be guarded by a standard railing (or the equivalent as specified in paragraph (e)(3) of this section) on all open sides 4 feet or more above floor or ground level. Wherever tools, machine parts, or materials are likely to be used on the runway, a toeboard shall also be provided on each exposed side.

Runways used exclusively for special purposes (such as oiling, shafting, or filling tank cars) may have the railing on one side omitted where operating conditions necessitate such omission, providing the falling hazard is minimized by using a runway of not less than 18 inches wide. Where persons entering upon runways become thereby exposed to machinery, electrical equipment, or other danger not a falling hazard, additional guarding than is here specified may be essential for protection.

1910.23(c)(3) Regardless of height, open-sided floors, walkways, platforms, or runways above or adjacent to dangerous equipment, pickling or galvanizing tanks, degreasing units, and similar hazards shall be guarded with a standard railing and toe board.

1926.106(a)

Employees working over or near water, where the danger of drowning exists, shall be provided with U.S. Coast Guard-approved life jacket or buoyant work vests.

1926.106(b) Prior to and after each use, the buoyant work vests or life preservers shall be inspected for defects which would alter their strength or buoyancy. Defective units shall not be used.

1926.106(c) Ring buoys with at least 90 feet of line shall be provided and readily available for emergency rescue operations. Distance between ring buoys shall not exceed 200 feet.

1926.106(d) At least one lifesaving skiff shall be immediately available at locations where employees are working over or adjacent to water.
