RESPONSES TO QUESTIONS

Tygart Dam Bulkhead Hoist Repairs Questions and Answers

Q1. When does the level of the lake go below 1039.5, and how long does it normally stay at that level?

A1. Section 01 35 00.00 08 SPECIAL PROCEDURES, paragraph 1.13 POOL LEVELS references a chart for normal elevation based on actual recorded lake levels. The chart was omitted from the package, but is included in Amendment 0001. The graph shows typical pool levels throughout the year based on historical data for the period January 1981 through December 2010.

Q2. Can both bulkheads be removed for repair and for how long can they be off site?

A2. No. One bulkhead must remain available for use. Section 05 12 00 STRUCTURAL STEEL, paragraph

BULKHEAD REHABILITATION has been revised to clarify this and to add that the riveted bulkhead must be repaired first, followed by the welded bulkhead.

Q3. Is there more information about the trash boom listed in (Specification Division 01, Section 01 35 00.00 08)

1.10.4?

A3. Additional information has been added to the specifications to describe the trash boom and its construction.

An additional requirement has been added to replace any fittings removed for movement of the trash boom with new stainless steel fittings.

Q4. How will each square foot of area to be painted be measured? Particularly small steel member and small areas to be painted. Industry standard is usually one square foot minimum per repair area. For instance if a rust spot is 4"x7", often an irregular shape, will it be paid at 0.2 SF or 1 SF? This can matter greatly on how these SF pay items are priced.

A4. Anchorages will be measured by each, consisting of the anchorage plate, bolts, and adjacent area of welded members. Only repair of existing paint coating on structural members will be measured by the square foot.

In most situations, this work will consist of cleaning and painting structural members (beams, angles, gusset plates, etc.). These will probably be areas larger than 1 SF, however, the specification has been revised to consider the minimum repair to be 1 SF for measurement purposes.

Q5. Can an additional site visit be arranged?

A5. An additional organized site visit will not be scheduled at this time. Individuals desiring to view the site may email their request to ryan.moore@usace.army.mil. Access to the Tygart Lake dam is not guaranteed and is dependent on availability of USACE personnel. Questions will neither be solicited nor answered should this additional site visit occur.

Q6. Will we receive a copy of the pre-bid sign-in sheet?

A6. A copy of the pre-bid conference sign-in sheet is being made available as part of this Solicitation

Amendment.

Q7. Can the AISC certified fabrication shop be waived for this work? The canopy construction and the bulkhead saddle modification can be done locally and save the Corps some costs. Keeping AWS inspection of course.

A7. The requirement for AISC certified fabrication shop has been deleted.

Q8. What is the intent of the delivery barge in section 1.6 Lifting Plan, Page 3 section 01 73 19.00 08? Is it expected that the new bulkhead will be delivered into in final installation by barge?

A8. This was an error in the specification. A revised section 01 73 19.00 08 is included in this Amendment.

Q9. Can we use the existing hoist monorail and other hoist platform structure to access and rig the bulkhead guides?

A9. The existing hoist monorail and other hoist platform structure may be used, however, a plan for the intended and applicable calculations, signed by a registered Professional Engineer, must but be submitted for approval prior to performing the work. This shall be included in the Construction Site Plan Submittal.

Q10. Can a floating plant platform be anchored to the bulkhead guides to keep the access and containment stable?

A10. Mooring rings are provided on the upstream face of the dam as noted in Section 01 35 00.00 08 SPECIAL

PROCEDURES and have been used for mooring floating plant in the past
