TDS-NAVFAC EXWC-CI-1401, New Earth Covered Magazine (ECM) Design

The U.S. Navy Physical Security Enterprise and Analysis Group (NPSEAG) tasked the Naval Facilities Engineering and Expeditionary Warfare Center (EXWC) to develop new designs for a family of four modular earth-covered magazines. The requirements for this effort are supported by the Naval Ordnance Safety and Security Agency (NOSSA) and the Navy Munitions Command (NMC).

High Performance Airfield Pavements (HPAP)
Short Take-off and Vertical Landing (STOVL)
Foreign object debris (FOD)
TDS-NAVFAC EXWC-CI-1402, High Performance Airfield Pavements HPAP)

The F-35B is the Short Take-off and Vertical Landing (STOVL) variant of the Joint Strike Fighter (JSF). It has been shown that its exhaust has a 50 percent probability of spalling standard airfield concrete pavement during a single Vertical Landing (VL) operation. While the spall depth is limited, it represents the potential of generating foreign object debris (FOD), which can damage the aircraft.   The failure mechanism for the JSF issue is spalling due to the super heating of water in the concrete. When the heat and pressure from the downward facing nozzle hits the concrete surface it vaporizes the water in the concrete exposing the material to stresses higher than it can handle. The solution developed at NAVFAC EXWC was to create a concrete mix that could be produced by conventional equipment and methods that has three unique properties.

Mitigating Concrete Damage
Engine Exhaust Surface Temperature below 500 degrees
TDS-NAVFAC EXWC-CI-1403, Mitigating Concrete Damage Caused by Engine Exhaust Surface Temperature below 500F

The Office of Naval Research and the Air Force Civil Engineer Support Agency sponsored an experimental investigation by the Naval Facilities Engineering and Expeditionary Warfare Center (NAVFAC EXWC) to develop candidate pavement systems that would be resistant to the thermal/blast effects from the exhaust and the spilled liquids from these aircraft. Simulated high temperature exposure tests were conducted on candidate pavement systems at the NAVFAC EXWC Aircraft Engine Simulation Facility (AESF). This facility, which operates with natural gas, is capable of simulating the heat flux of various jet engine exhausts, from the F/A-18 APU to the V-22, AV-8B and JSF F-35 aircraft main engines.

Building Information Modeling (BIM)
Certified Facility Managers (CFM)
Energy Conservation Measures (ECM)

Naval Facilities Engineering and Expeditionary Warfare Center (NAVFAC EXWC) is tasked to create, demonstrate, and validate a standard Building Information Modeling (BIM) object class data exchange library for select standardized designs/facility types that specifically address critical building envelope object-based parametric modeling.   Preliminary findings indicate that the Navy would gain the most value from BIM by specifying design and constructability models to contain key performance attributes. More specifically, the thermal properties found under type properties in family objects are critical building attributes within the model required to utilize BIM for building level reporting of Certified Facility Managers (CFMs).

Concrete Repairs
Corrosion Inhibitors
Organic compounds ester-amines and alcohol-amines
TDS-NAVFAC EXWC-CI-1405, Corrosion Inhibitors for Concrete Repairs

Despite the advances in corrosion control technology, corrosion of reinforcing steel is still the primary cause of deterioration of concrete waterfront structures.  This TechData Sheet indicates that there is no benefit of using of corrosion inhibiting admixtures in concrete repair patches has been demonstrated by this investigation. Differences in the patch material and the existing concrete material, which are responsible for the initiation of corrosion cells, have not been shown to be altered sufficiently to cause a reduction in activity over the test period.

Broad Area Maritime Surveillance (BAMS)
Unmanned Aerial Vehicle (UAV)
Fuel overheating

The Global Hawk, the Preproduction Broad Area Maritime Surveillance (BAMS) Unmanned Aerial Vehicle (UAV) and by extension related UAVs can suffer from limitations due to excessive heat loading during ground support activities. These heat problems are caused by the UAV using the fuel (via heat exchanger) as a heat sink to cool the avionics.  It was found that when the aircraft is operated by motivated trained personnel that minimize the time the UAV is exposed to direct sunlight the fuel system does not overheat.

New Concrete Construction
Uniform Facilities Guide Specification (UFGS)
Marine Concrete
STADIUM concrete
TDS-NAVFAC EXWC-CI-1407, Quality Assurance of New Concrete Construction

The NAVFAC methodology to enhance quality assurance for new concrete construction is a requirement of the Uniform Facilities Guide Specification (UFGS), section 03 31 29, Marine Concrete. It is expected that military construction will incorporate it to achieve more sustainable reinforced concrete structures. The corner stone of the approach employs a validated software program, STADIUM®, which allows users to predict the service life of the concrete under different types of environmental exposure conditions. Owners and engineers can now have a tool that quantifies the beneficial effects of various chemical compositions provided by specific types and blends of cements, fly ash, silica fume, and blast furnace slag.

Marine Concrete Repair TDS-NAVFAC EXWC-CI-1408, Enhanced Guidelines for Marine Concrete Repair

Naval Facilities Engineering and Expeditionary Warfare Center (NAVFAC EXWC) develop a repair specification based on enhanced guidelines for marine concrete repair and document a full-scale concrete repair project accomplished using these enhanced specifications. The completed project serves to demonstrate the practicality of the specification and act as a prototype for Architectural and Engineering firms who are responsible for future concrete repairs Navy wide.

High Volume Fly Ash Concrete (HVFA)
Concrete mixtures
Portland cement
TDS-NAVFAC EXWC-CI-1409, High Volume Fly Ash Concrete for Navy Structures

Naval Facilities Engineering and Expeditionary Warfare Center (NAVFAC EXWC) engineers demonstrated and evaluated the usage of high volume fly ash (HVFA) concrete mixtures under full-scale production processes containing 50% less Portland cement while achieving increased durability and maintaining strength properties. By replacing 50% of the Portland cement with Class F fly ash, reduced cracking, decreased permeability, and increased electrical resistivity of the concrete can be achieved. All of these properties lead to a more durable material and a decrease in corrosion related deterioration while maintaining compressive strength properties.  HVFA mixtures are placed using the same tools and procedures as those used in conventional concrete construction. Additionally, by replacing half of the Portland cement with fly ash, there is a large reduction in the amount of CO2 emissions associated with the material.

Floating piers
Berthing piers
Re-locatable piers
TDS-NAVFAC EXWC-CI-1410, Floating Double-Deck Pier

The Floating Double-Deck Pier (FDDP) is a new generation of berthing pier that offers a cost-effective and sustainable alternative to traditional pile supported piers.  The design uses standardized modules manufactured at one location to create an easily reconfigurable and re-locatable pier that provides the lowest life-cycle cost for Navy piers. The FDDP is ideal for all legacy and envisioned classes of U.S. Navy ships except CVN’s and submarines.
