Project Summary |
| Pier Design and Facilities Consulting Peck Marine Terminal, Chesapeake, VA |
Precon Marine is currently finishing construction on a 260' concrete pier serving as an extension to the existing 160' wharf. This Millennium design uses 18" square concrete piles, cast in place pile caps and prefabricated concrete slabs. A mooring analysis was conducted and bollards, cleats and fendering were included in the project. Phase II is proposed to include lengthening the pier another 870' for a total of 1,290'. In addition to the design services for Precon Marine, we are also performing special inspections and port consulting for Peck Marine Terminal as they move forward.

| Brambleton Avenue Bridge The Hague, Norfolk, VA Precon Marine, Inc. |
Millennium Engineers is currently providing supplemental engineering services for the Brambleton Avenue Bridge Repairs in Norfolk, Virginia. This includes designing temporary support hangers for existing utilities while demolition and construction of the deck is performed. Also the repairs call for the replacement of the bearing pads for the girders. We have engineered aand prepared plans for a jacking mechanism to jack the existing bridge structure enough to accomodate the replacement of the existing bearing pads with new ones.

| Medical Center Bulkhead Renovation Veterans Affairs Medical Center, Hampton, VA Paul Finch & Associates, P.C. |
Sub-consultant to provide design drawings and specifications for repairs to 4,760 LF of existing bulkhead around the V.A. Medical Center Hampton Virginia property. Responsibilities included providing surveys, research and detailed drawings of the existing conditions, including identifying subsurface utilities and obstructions as well as many storm outfalls that are to be extended through the new bulkhead repair. There were several different types of existing bulkheads of different ages and condition along the nearly one mile long stretch of shoreline that needed to be identified, researched and analyzed to ensure proper repair design. The project also includes construction and post construction services including consultation, inspections and preparation of Record Drawings. |
| Repairs to
Piers 4, 5, 8 and 14, Norfolk Naval Station, Norfolk, VA |
Primary consultant to provide four separate sets of structural engineering design drawings and specifications for above and below deck structural repairs on these four piers. Included are general concrete spall repairs, concrete curb replacement, pile cap repairs, pile jacket installations, broken concrete pile repairs, utility support repairs, fendering repairs and new deck painting. The project also includes design for modifications to the fendering system at pier 4. This modification involved the installation of prestressed concrete piles with ultra-high molecular weight poly-ethylene facings to accomodate floating fenders. |
|
Repairs to
Bulkhead Cove Point Condominium Association |
Primary consultant to provide design drawings and specifications for repairs to a timber bulkhead that was losing fill beneath three concrete parking structures and condominium buildings. Due to the complexity of the original design, design repairs had to take into account existing finger piers and cantilevered slabs and building alcoves that make access to the existing bulkhead difficult.Also Millennium Engineers was tasked with preparing the Virginia Marine Resource Commission permit application for approval. |
| Design
Repairs to Bulkhead V-121, Norfolk Naval Station, Norfolk, VA |
Primary consultant to provide structural engineering design drawings and specifications for repair of this 1933 bulkhead. Millennium Engineers was tasked to conduct a structural investigation to determine the extent of deterioration due to impact, sulfate attack or other deteriorating action located above and below the water line to the bulkhead. The final design included above and below water repairs, void and sinkhole repair, re-paving, stripping and drainage for all parking areas. The allowable wheel and outrigger loads and verification of the uniform live load for the bulkhead was also determined. |
| Lift Slip,
Wharf and Pier 55 Fendering, Little Creek Amphibious Base, Norfolk, VA |
Primary consultant to provide structural engineering design plans and specifications for a new fender system on three structures to replace the existing timber fender system that is currently in a state of disrepair. The new fender system utilized plastic composite piling and plastic timber and accommodate the new SEABOSS modular Lightering System. Six mooring dolphins with solar powered navigational lights were provided at the end of Pier 55 to assist with the berthing of the SEABOSS modules. Repairs were designed to prevent fill loss and to protect the bulkhead from the larger wakes generated by tugboats. For the Lift Slip and adjacent bulkhead, a structural analysis determined the maximum allowable mobile crane outrigger loading. |
| Design for
Crane Hardpoint on Wharf, Little Creek Amphibious Base, Norfolk, VA |
Desert Cove was originally constructed in 1953. The original design did not account for the large concentrated loads being applied in today's environment by mobile cranes and vehicle loads. The existing concrete wharf did not have the structural capacity to support the large mobile cranes used in current operations. The project included the design for the construction of a 32 foot x 90 foot crane hard-point to replace a section of the existing wharf to meet the requirements of a 300-ton mobile crane and a fender system to accommodate the new SEABOSS Modular Lightering System. |
| Boat
Storage Facility, Lake Chesdin, Dinwiddie County, Virginia, |
Sub-consultant to
provide design plans and specifications for this boat
storage facility at Lake Chesdin. This structure is of
timber design on timber piles at the end of a pier and
has a storage room and two bays with lifts for dry boat
storage.
|
| Bridge 2107
Pier Repair, Little Creek Amphibious Base, Norfolk, VA |
The Navy determined that based on a 1997 Bridge Inspection Report that Bridge 2107 was in need of repair. The inspection identified a number of the support piers displayed signs of deterioration. Millennium Engineers was chosen to investigate the concrete damage and determine its cause and extent, to provide modifications to the bearing pad and/or anchors to correct the spalling problem and prevent the damage to the pier from reoccurring and to prepare repair drawings, specifications and construction cost estimate to restore the integrity of the bridge pier. |
| Precon
Bulkhead Extension, Chesapeake, Virginia BBB LLC |
Primary consultant to provide structural engineering design plans and specifications for an extension to the existing bulkhead along the waterfront at BBB LLC's Chesapeake, Virginia facility. This extension along the southern branch of the Elizabeth River is proposed to have a deeper water depth and provide better mooring options than the present bulkhead. This project included design of a new sheet pile bulkhead, associated wale and tieback system with earth anchors. |
| Various
Repairs to Drydocks 2, 3, 4 & 8, Norfolk Naval Shipyard, Portsmouth, VA |
Primary consultant to prepare structural engineering design drawings and specifications for ten various projects around the drydocks that included structural and pipe support repairs in drydock pumpwells, new access ladders for maintenence of sluice gates, a platform beneath a wharf for inspection of rivergates, new trash racks, new stoplog seats and new containment shroud tiedowns for the four drydocks. |
| Evaluate
Caisons for Drydocks 6 & 7, Norfolk Naval Shipyard, Portsmouth, VA |
Primary consultant to perform structural analysis of the caissons at Drydocks 6 & 7 to determine the minimum allowable shell plate thickness for all areas subject to river pressure in general and for the areas where ultrasonic test readings were accomplished. We provided a detailed report with findings, conclustions, recommendations and construction cost estimates to implement the recommended repairs. |
