About this file
This is an industry day Q&A document containing 23 questions and responses regarding the replacement of steel sector gates with Fiber Reinforced Polymer (FRP) gates at the Canaveral Lock in Brevard County, FL. The questions focus on design considerations, quality control, manufacturing processes, and technical specifications for the FRP sector gates, which must integrate with existing steel hinge and pintle assemblies while maintaining a 100-year service life.
Key technical requirements include managing gate buoyancy, thermal expansion, manatee protection systems, and water flow capabilities through screened/grated openings. The questions address manufacturing quality control plans, design review periods, delivery logistics, installation procedures, and maintenance considerations. The document is accompanied by an industry day announcement scheduled for January 16, 2025, with responses to questions due by January 13, 2025, 11AM EST, and final feedback due by January 30, 2025, 10AM EST. The project is managed by the Jacksonville District of the U.S. Army Corps of Engineers, with the gates to be installed at 1000 Mullet Road, Cape Canaveral, FL 32920.

Canaveral Industry Day
| Industry Day Questions | ||||
| Canaveral Industry Day | ||||
| No. | Project | Topic | Question | Responses |
| 1 | Canaveral Sector Gate | Design and Manufacturing quality control plans | On all of the similar VARTM projects have a design and fabrication requirement to demonstrate proof of concept, design adequacy, strength and material testing. This is new to USACE and to ensure those intents are met. Due to the complexity, does industry recommend having a design quality control plan separate from the fabrication quality control plan? Is that level of quality control appropriate or it is redundant? | |
| 2 | Canaveral Sector Gate | Design and Fabrication | For design is design charrette, 30, 60, 90, 100, and Final design necessary to design this gate? Or would industry recommend shorting less design reviews? This Performance Period is 18 mo., what design period is recommended or this type of complex design? 6m, 12m, 18m, 24m, etc? What is the approximate fabrication time needed after the design period? What is the approximate delivery time need to deliver the gates and is the hydrographic survey data all that is needed to delivery by barge? | |
| 3 | Canaveral Sector Gate | Bid item schedule, Base and Options | This p&s package is different that other performed by USACE for similar projects. Is the list of line items clear or does it need to be clarified further? Is the formats for the supply contracts used on prior contracts Lock and Dam 16 (W912EK24R0033), WP Franklin Spillway Vertical Lift Gates (W912EP24C0009), LaGrange and Peoria Wicket Gates (W912EK21F0012), Lockport gates (W912EK21R0026) more clear to Industry for design, testing and fabrication of those gates? | |
| 4 | Canaveral Sector Gate | Design, framing and connections | How can the gate be manufactured to reduce buoyancy so that it can lower under self-weight without increasing self weight above the existing steel gate's weight? Is open framing using VARTM an option? Are there other options beyond the frame construction to reduce the weight and facilitate fabricating the gate? | |
| 5 | Canaveral Sector Gate | Assembly & Delivery | The existing gates are radial, pie shaped geometry with approximately 55' radius, 60 degree angle and 25' high without the walkway. The walkway on the existing gate is about 7.5' above the gate, which would make the height approximately 33' high. The plan is to have this delivered by barge to the Canaveral Lock site fully assembled to lift into the lock recesses. What type of connections would be possible for the gate components and the walkway? What are their advantages and disadvantages? Is a removable components or connection feasible in order to facilitate maintenance/repairs/rehabilitation? | |
| 6 | Canaveral Sector Gate | Design to work with existing infrastructure, fabrication and installation | The existing lock was designed around a pinned pintle ball and a split bushing system with associated receiver to aid in install and removal and associated gate maintenance. Due to the current pintel ball design with split bushings and metal receivers; what concerns does industry have with regard to design and incorporation to support the pintle ball pin being set within the lock chamber floor. What thoughts can assist with identifying a standardized approach to assist with design and also a common bid item(s)? This question aligns concerns with lifting connections and ability to readily install a gate with installed pintel balls and bushings. | |
| 7 | Canaveral Sector Gate | Design of hinge and pintle assemblies | Can the FRP design readily accept the existing hinge, pintle, and bushing systems; while still maintaining the desire design loads without impacting FRP get operations? Desire is to establish whether existing dimensional controlled components (hinges, bushings, pintel balls, etc) that are common across the USACE enterprise be preserved . Goal being is to save in overall costs without moving the risk and control of the design and operations back to the government. If the existing metal components are design suitable; can these then be removed from this solicitation? | |
| 8 | Canaveral Sector Gate | Design, fabrication and future O&M | With the potential that the gate design will be driven by deflection control and the gates and associated bottom seals will be set in the dry and rewatered and floated; what design consideration can be taken to relook the potential for gate seals to be set in a watered scenario to account for gate floatation forces and diminish gate dewater deflection/sag. Is it feasible for an FRP design for a watered state and then witness reductions in resin, structural metal framing, and fabrication all leading to reduced costs? What additional support components would be needed for future dewaterings; such as jacks, shims cribbing, feet, etc? | |
| 9 | Canaveral Sector Gate | Fender system and manatee protection | The components for the fenders and manatee systems are regularly changed when damaged. Is there any recommendation from industry to include for these components to be more resilient and easily provided by industry for repairs or replacement that should be including or clarified further to meet those intents? | |
| 10 | Canaveral Sector Gate | Water flow and Manatee Protection | Similar to the resiliency concerns noted for the gate openings. Those openings will need to be screened or grated to allow for water flow when opening and closing the gate, and to reduce the weight of the gate. It will need to be rigid enough to prevent marine life from damaging it and to prevent access to within the gate. Should that material be specified for FRP and if so, does industry prefer some widely used frp grate or screen product that should be consider to be included as a submittal for approval? | |
| 11 | Canaveral Sector Gate | Lifting Connection | Our intent is to have the lifting machinery connection very similar in geometric layout to the existing gate. We would like to have the gate fully assembled and lifted for install. Are there any recommendations you have for lifting connections? If using a steel lifting assembly attached to the gate, what are some recommendations for load transfer into the FRP gate? Any recommendations for avoiding wear/tear of repeated loading? | |
| 12 | Canaveral Sector Gate | Quality Control | How do you validate the design and perform quality control of the overall structure? | |
| 13 | Canaveral Sector Gate | Manufacturing | How would you build a sector gate to achieve the performance with radial motion and curved skin plate? | |
| 14 | Canaveral Sector Gate | Framing and connections | Depending on your recommended design approach, what do you recommend for general structural framing and associated connections? | |
| 15 | Canaveral Sector Gate | Hinges | Any recommendation for attaching the hinge elements at the top and bottom of the gate to the gate? Any recommendations for making the hinges or their bearing elements removable/replaceable for maintenance? | |
| 16 | Canaveral Sector Gate | Hinge and Pintle Assemblies | There are notes on the plans and details in specification for the fabricator to use to complete the design. Is there enough information for industry to submit a quality bid? |
17 Canaveral Sector Gate Hinge and Pintle Assemblies Are there any issue with getting quality steel? Can those assemblies be casted or forged steel?
18 Canaveral Sector Gate O&M Hinge and Pintle Assemblies Any recommendations for making the hinges or their bearing elements removable/replaceable for maintenance?
| 19 | Canaveral Sector Gate | Thermal expansion | Steel sector gates have some challenges with thermal expansion over a wide range of service temperatures. These problems typically occur at the bottom seal and the rack portion of the rack-and-pinion operating machinery (binding of rack and pinion at high temperatures). The rack is typically surface mounted at the top of the gate along the circumferenctial curvature of the skin plate. How can thermal expansion of the overall gate be controlled? Should there be any concern about differential thermal expansion of the composite gate and the steel rack of the rack-and-pinion? |
| 20 | Canaveral Sector Gate | Structural Stability and Monitoring | Do you have experience with instrumenting and/or monitoring composite structures? What type of systems (e.g. fiber optic, wireless, etc.) can be applied to monitor the structural health (e.g. deflection, protrusion of the gate surface etc. )? |
| 21 | Canaveral Sector Gate | Manatee Protection | For incorporating the manatee array on the gate is there any recommendation from industry on when to include that contract into the project? At the beginning, middle and end of fabrication? |
Or are there other times during the design?
| 22 | O&M | O&M Manuals and Preventative Maintenance | Service life of FRP gate and steel components is 100 yr. Is there any key details that should be included in for adequate long term maintenance. |
| 23 | Canaveral Sector Gate | Risks | Do you see any additional risks in this contract that would affect costs, design or fabrication? If there is some additional risk what would you recommend further clarifying to reduce those risks? |
