W912DR22B0014 Fishing Creek Jetty Rehab and Maintenance Dredging Bidders RFI’s 6/22/2022

Q1: In the stone design it is spec-ed that nothing should be higher than 2:1. The quarry to be used (Vulcan in Havre de Grace, MD) states they usually do 3:1, but is unsure if they can guarantee 2:1. Is that acceptable?

No, bid as shown.

Q2: Underlayer stone spec ranges from 370-2500 lb. This is bigger than Vulcan’s Class III, but smaller than HRBT Type 3 Armor (range 450-3400 lb.). If Vulcan can off either, which is more desirable?

HRBT Type 3 Armor could possibly be considered. However, please clarify what specifically HRBT refers too? What is the W50 for this material?

Q3: For the 1.5 Capstone (range 2,200 to 4,600 lb.) Vulcan suggests the HRBT Type Armor 2 with a range of 750lb to 5600lb. Is that acceptable?

No, bid as shown.

Q4: All products have a bottom value of W-0 (0% smaller). Normally the quarry asks for 10% on unders.

Is the 10% acceptable or should it remain at 0%?

No, bid as shown.

Q5: What is the offset from the toe of the jetty?

We do not understand the question. All dimensions are taken from the jetty centerline (baseline).

Can you please better define the monitoring to be performed so that we can determine a quantity of monitoring locations? We are getting varying interpretations from experts reading the spec regarding the number of monitoring setups needed. Are we to just do representative testing by setting up in a few locations or do we need to set up at every single house and structure withing a 500’ radius of our work? I see where we are to do representative test of every type of structure so we have timber pile structures, decks, slab foundations, concrete pile foundation etc. Don’t think there are any pools.

From specifications: Place seismographs at locations on or at the base of the structures to obtain the highest peak particle velocities. Representative structures shall be defined as one of each foundation type (pile foundation, masonry, concrete, slab on grade). Monitor no less than three structures within the 500 feet of the active work area.

Above should be interpreted as follows: A minimum of 3 seismographs will be required within 500 feet of construction activity. Depending on the structure’s foundation type, it could be more. However, it is typically unlikely that foundations in a given area will be different from structure to structure. For example, it is not common to have a structure supported on piles next to one that will be on a masonry or concrete foundation. It is the contractor’s responsibility to determine the foundation types to accurately plan how many seismographs will be needed. Placement of seismographs will typically on structures closest to the work.

W912DR22B0014 Fishing Creek Jetty Rehab and Maintenance Dredging Bidders RFI’s 6/22/2022

Our big concern in addition to the questions is the 19 individual homes. Each one could easily complain about vibration.

The intent of the monitoring requirements is to ensure that construction vibration levels do not exceed peak particle velocities at frequencies that have the potential to cause damage to existing structures. It is not intended to prevent complaints. It is likely that vibrations will be felt by homeowners, etc. at much lower levels than the thresholds that induce damage.

Within the radius there at least 18 or 19 house, a large parking garage, a museum, a hotel, a restaurant, a commercial hotel and a new structure under construction.

The vibration monitoring consultant/expert should have the knowledge and expertise to determine which of the aforementioned structures should be monitored. If it is determined that multiple structures sensitive to vibration are within the 500 foot radius, then it is possible that more than 3 monitors will be necessary.

ISSUED TO: Baltimore District US Army Corps of Engineers Navigation Branch 2 Hopkins Plaza Baltimore, Maryland, 21203 Attn: Kevin Brennan

EFFECTIVE DATE: June 9, 2022

PROJECT LOCATION: Fishing Creek Federal Navigation Channel Chesapeake Beach, Calvert County, Maryland

DESCRIPTION OF CERTIFIED PROJECT: To hydraulically dredge the Fishing Creek Federal navigation channel to its authorized depth of 7 feet MLLW (plus at least one foot of overdepth) for a width of 100 feet, and to dredge a 75-foot long by 10-foot deep access channel parallel to the existing jetty, resulting in approximately 22,000 cubic yards of material consisting of clay, mud, sand, silt, and shell. Dredged material is proposed to be hydraulically pumped to a nearby existing upland placement site. The work also includes the rehabilitation of the southern jetty along Fishing Creek by placing 1.5 to 3 ton capstone to restore the jetty elevation 2.7 feet higher than originally constructed to reduce overtopping, and increase the jetty crest width to 16 feet.
