Contractor_Questions_and_Customer_Answers_13Mar19.docx

Questions and Answers:

1) What is the weight/size of the existing mushroom anchors that need to be removed? This can have a significant effect on price as it may require a larger vessel.

A) 300 lb.

2) Will the contractor be able to use the Naval Station Annapolis basin as a staging area and a mooring location for installation vessels during the period of performance of the project? This will reduce cost to the government by avoiding slip costs or extended transit times.

A) The Naval Support Activity can be used as a staging area. Contractor needs to provide size and number of vessels to determine if moorings are available for the duration of the project.

3) Will the government consider providing dive services from the SCRD Dive Locker to support the project in order to reduce the overall project price? The unknown nature of the condition of the current moorings will require a contractor to have some contingency funding for diving operations which can be costly. If the SCRD dive locker can support full time during the removal phase, and as needed during the installation phase, a reduced price can be offered. If desired, we can submit pricing with government furnished diving services and contractor furnished diving services.

A) Navy diving support is not available

4) Please confirm that the desired penetration for new anchors is 31 feet below the mudline.

A) The requirement is that the anchor would hold a lateral pull of 8600 lbs. 31 feet of helical anchor shaft is what is expected to meet that requirement, but is up to the contractor to determine.

5) If 31 feet of penetration is confirmed, quantity of C1100138 needs to be increased. Each C1100138 is 7 ft long and each C1100247 is 10 ft long. This would require 3 x C1100138 per mooring, for a total of 117.

A) See number 4.

6) Line items 14 and 15 appear to capture the same part.

A) Concur. Line Item 15 will be removed. See Line Item 14 instead.

7) Would the government consider a “Stormsoft” Mooring downline in lieu of the 1” anchor chain? This keeps the mooring line off the bottom and causes less damage to bottom grasses and shellfish habitats, and provides shock absorption for boats swinging in strong weather.

A) 1" anchor chain is required.

8) Can the government provide a vessel capable of 8600 lbs bollard pull for the testing phase? Contractor will provide all other equipment. This is a large bollard pull and will require a vessel other than the one used for mooring installation, increasing cost to the government.

A) Contractor is to provide a vessel capable of the pull test. The test does not have to be a dynamic pull with a moving vessel. It can be conducted with an anchored barge equipped with a winch capable of reaching 8600 lbs. of pull.
