These options are presented and described below from the least expensive to the most expensive. These prices do not represent the best value to the worst value, only the initial construction related costs. The best value is much more difficult to determine as longevity and long-term maintenance costs are very complicated, and in some ways not possible to predict. These options are the result of preliminary information and are not to be construed as having the same accuracy derived from a thorough engineering design. Additionally, there are many factors that can significantly affect costs, including the availability of contractors to bid on the job, time constraints for construction, and extensive requirements by oversight agencies. Drawings of the existing pier can be seen in Figures 1 and 2. OPTIONS 1. 8' x 132' Pedestrian Timber Pier $391,000 This option involves the construction of a pedestrian timber pier in a new location without any removal or renovation of the existing pier. This option only makes sense if the University wants safe access to the water while they take time to design and raise money for the reconstruction of the commercial grade pier. This design will accommodate a 60 psf pedestrian live load and a new 5-ton crane. It is a much longer pier since it will not take advantage of the existing gravel approach and concrete abutment. The expected lifespan is 20 years, with occasional replacement of corroded timber parts. Figure 3 shows an elevation view of what this option may look like. PINE TREE ENGINEERING Page 1 2. 18' x 93' H-10 Vehicle Timber Pier $575,000 This option involves the complete demolition of the existing pier up to the abutment and the construction of a timber pier rated to handle a 200 psf live load and a 20,000-pound H-10 vehicle. The H-10 vehicle represents a 16,000-pound load per axle and 8,000 pounds per wheel, or exactly one half of the H-20 vehicle which is, in general, a standard public transportation loading. For further comparison, a maximum ambulance weight can be around 10,000 - 15,000 pounds. Timber pile bents will be spaced 16 feet apart, with pressure-treated timber frame and decking. The expected lifespan is 20 years, with occasional replacement of corroded timber parts. Figure 4 illustrates this option. 3. 18' x 93' Steel, Concrete, and Timber Pier $726,000 This option includes the reconstruction of the facility with steel piles, concrete pile caps, steel I-beams, and timber decking. It is a near replica of the existing configuration but is supported with steel piles rather than the large stone filled caissons. It includes the demolition of the pier up to the abutment and like all the options considered, it includes a 5-ton crane. The steel and concrete will require treatment as corrosion sets in, but should last 50 years. Timber members will need the same replacement schedule that the existing pier has required. This option would look similar to Figure 4. 4. Replicate Existing 18' x 93' Pier $887,000 This option is a new replica of the existing configuration. After removing the existing members, it includes new 15' diameter stone filled caissons, 15' square pile caps, and steel I-beams supporting a timber frame deck. Like Option 3, the longevity will be greatly enhanced with regular treatment of the steel and concrete components and periodic replacement of the wood timber members. The steel and concrete components should last 50 years with proper treatment. Timber members will need occasional replacement, with increasing regularity as it ages to 20 years. Regular treatments and/or sealants do improve the longevity of wood members but are not often implemented in commercial pier settings. This option would look similar to Figure 2. 5. 18' x 93' Steel, Concrete, HCB Deck Pier $919,000 This option is the same as above but with a hybrid composite beam (HCB) deck. With treatment as corrosion takes place, the steel and concrete components should last 50 years. This option would look similar to Figure 2. Though the projected lifespan of the HCB deck is greater than 50 years, it will need to be dismantled with the other components. The price for a concrete deck may be comparable to the HCB since the HCB is much easier to install. PINE TREE ENGINEERING Page 2 6. 18' x 93' Hybrid-Composite Pier $973,000 This option includes a composite configuration almost exactly like the pier at the Downeast Institute on Beals Island, which serves as the marine field station of University of Maine at Machias. It would have concrete filled composite piles, pile caps, and the HCB deck. This option will require much less maintenance than the others. Maintenance should include periodic spray or sealant to the concrete deck surface and elastomeric sealant between exposed concrete/composite joints to limit salt water contact with the concrete. With proper maintenance, this option should last 75-100 years and would look similar to Figure 4. 7. Renovate Existing 18' x 93' Pier with Hybrid Composites $1,138,000 This option incorporates the existing caissons, which are likely well founded in the river bed, by wrapping the caissons with composite panels. It requires chiseling the existing pile caps and extending the composite panels to support the hybrid composite beams (HCB). The pile caps, which are square, will need to be cut and/or chiseled to fit inside the round caisson panel system. The term hybrid composites in this report refers to concrete wrapped with composite paneling and internal steel or composite concrete reinforcement. This option should last 75100 years with proper maintenance and would look similar to Figure 2. MATERIAL CHARACTERISTICS When considering the above options, it is helpful to understand elements that will influence longevity, cost, and maintenance in a marine setting. Wood: Wood is relatively inexpensive, readily available, and generally very easy to install, and is proven to be effective for maritime use. However wood is subject to decay and requires periodic replacement. Wood has a given service life of 20 years, which means that most of the members will need to be replaced by the time the structure is 20 years old. Because it is a natural product, each piece of wood has different properties, and some members will need to be replaced sooner than others. Extreme sunlight and excessive moisture are the major contributors to decay. Regular treatments and/or sealants improve longevity, but are not often implemented in commercial pier settings. Reinforced Concrete: Concrete requires virtually no maintenance and has a service life of 50 years. Concrete mixtures are being continually tested, and some are claiming a longer service life. Historically, the trouble with concrete in marine settings is twofold. First the salt crystals work their way into the concrete pours and expand, a process which over time slowly breaks down the concrete particles. Secondly, wicking moisture works its way into contact with the steel rebar which slowly corrodes, expands, and breaks the steel/concrete bond, and the concrete eventually falls away. Sealants can be applied to extend its service life. PINE TREE ENGINEERING Page 3 Steel: Perhaps the most versatile material in relation to its variable strength properties, steel is also one of the most susceptible to corrosion. While still a popular material, steel needs great care to properly seal it from the elements. Steel has a given service life of 50 years as long as it is properly coated, maintained, and installed without damaging the coating. Ideally, if the coating could be properly maintained, steel would never corrode and its service life would be indefinite. However, this is never realized and is more difficult in marine settings where the steel is in constant contact with salt water. Composites (fiber-reinforced polymers (FRP)): While it is the most expensive of the materials, FRP is versatile, much like steel. The product is also very light, making it much easier to install. When treated properly, FRPs require very little, if any, maintenance. Sunlight can have some effect on the surface by creating a discolored and textured barrier. Though unsightly, these effects are superficial and do not penetrate the material structurally. Gel coats are normally added to mitigate UV effects. The technology is fairly new in bridge and other marine related construction, but composites have proven longevity and durability in the boating industry. Use of this material in other industries indicates a much longer service life than wood, concrete, or steel. Composites have an estimated service life of 75-100 years.
