PORT OF LONG BEACH UNIQUE DESIGN STANDARDS

Transcription

1 PORT OF LONG BEACH UNIQUE DESIGN STANDARDS As with most organizations the Port of Long Beach has many standards or policies which are unique to our organization. Most of these are due to the peculiarities of our business and specialties encountered in the port areas. These include such aspects as high truck traffic, high moisture content in the air, corrosive soils, heavier vehicular loads, and safety requirements within busy container terminals. It is important that the designer be aware of these unique standards and utilize them on future port projects. This will maintain consistency, allowing contractors the understanding of what they are bidding and also allowing maintenance personnel a consistent, uniform entity to maintain and repair. These unique standards can be classified as either design or construction standards, with most within the construction area. The construction standards are separated into five categories: Lighting/Electrical, Utilities, Roads/Paving, Structures/Buildings, and Railroad. A brief description of each of the specific unique standards follows. GENERAL Fire Protection: All design and construction within the Port shall be done in accordance with the NFPA 307 (National Fire Protection Association). This is a standard for Construction and Fire Protection of Marine Terminals, Piers, and Wharves, 1995 Edition. Modifications of these requirements must be formally approved by the Fire Department. LIGHTING/ELECTRICAL Ownership of Electrical/Telephone Structures: Within the port area (south of the State Lands boundary line which is essentially near the south line of Ocean Blvd.) all structures for electrical or telephone facilities (consisting mainly of manholes and ducting) are built and owned by the

2 Port. Through long term leases, these facilities are leased to SCE or GTE or others and they pull their own wiring and maintain the system. Designs for these facilities are coordinated with the utility involved and built to their specifications. Casing of foundation borings: Casings should be called for on the borings made for three or four-foot diameter foundations, particularly if they are near or exceed the ground water level. Protection of Poles: Protection of light poles must be considered wherever the pole is placed. The poles should be positioned in locations which will cause the least interference with the operations in the area. For poles within terminals, guard posts shall be placed around the pole according to Port standards. On street locations place poles behind curbs according to City roadway cross section standards or use MBGR or use breakaway bases. City ducting standards: Generally the City of Long Beach standards for ducting are used as a basic reference for lighting projects. Definitely if the project is for street lights. Street light conduit should be placed behind the curb with a minimum of 18-inches of cover. In-terminal lighting conduit should have 36-inches of cover and encased in red colored slurry. Cutoff standards: Care should be taken to direct lighting away from directly shining into vessel operator s vision or street traffic. Use cutoffs on luminaires where necessary. Lighting levels: Lighting levels for street lights and vehicular parking lots shall conform to a minimum of 1 fc, average of 1.5 fc, and a maximum ratio of bright-to-dark of 4:1. The general lighting level within an operating terminal is an average of 5 fc, with a minimum of 3 fc. Length of run limits: Generally the length of run between pull boxes should not exceed 400 feet. As curves are added between pull boxes the maximum length of run should decrease. Manhole standards for heavy loads: Manhole structures and covers shall be designed for the loads which they will receive from vehicles and/or containers which may be placed on them in the future. This should include not only those known presently but what maybe imposed in the future. The current in-terminal design vehicle is based on a Cat V925 Lift Truck, the front axle of which consists of four wheels each with a maximum load of 57 kips. Utilizing a 110 psi tire pressure each wheel will spread the 57 kip load over a 32-inch by 21-inch area. A n additional 10% impact factor is used in the design. The centerlines of the two closest wheels on the front

3 axle are 28-inches apart. In a container terminal, use of those standards for aircraft loads should be used if no other data is available. For roadways use a HS25 design vehicle load. Pull box standards for heavy loads: Pull box or vault structures and covers shall be designed for the loads which they will receive from vehicles and/or containers which may be placed on them in the future. This should include not only those known presently but what may be imposed in the future. See Manhole standards for heavy loads above for current in-terminal design vehicle. In a container terminal, use of those standards for aircraft loads should be used if no other data is available. Heavy load covers have been designed and used on other container terminal installations. These covers should be used on future installations with a check made for currently considered loads. For roadways use a HS25 design vehicle load. Red concrete: All electrical conduit installations within the Port, unless approved otherwise by the Chief Harbor Engineer, shall have a red dye added to the concrete encasement as a warning to future excavators of electrical installations. SCE concrete mix design: For duct runs which are SCE s red concrete is not acceptable. Check with SCE for their mix design requirements. Street light heights: Those lights used expressly for the lighting of streets, shall comply with City of Long Beach, Department of Public Works standards. Street and vehicular parking lot lights in the Harbor District shall be no more than 35 feet tall and shall be Marblite or steel with cobra head. Street light voltage & wattage: Generally two systems occur within the Port; either 480 volt or 240 volt. Investigation must be made of the systems adjacent to the site in question to determine the design of the new facility. Additionally, lights are high pressure sodium, either 250 or 400 watts, depending on the adjacent system. Photo cells: Photo cells used for the control of street lights shall be placed at the Myers cabinet or power source of the street lights in question. If a system is being placed under CalTrans jurisdiction the photo cells are to be placed at each light standard. Traffic signals, use City standards: All signals within the port are maintained by the City of Long Beach Public Works Department personnel and must conform to their standards.

4 Communications Conduit: When sections of streets longer than 500 feet are reconstructed a two-inch diameter conduit for future communications lines shall be included for the full length of the reconstruction. The conduit shall be placed 20 feet east or north (depending on direction of street) of the street centerline, unless other utilities occupy that location. The exact location shall be indicated on the as-built plans, as to location, extent, and depth. UTILITIES Abandonment: Within the Port jurisdiction, abandonment of a utility lines or pipelines should include the removal of those lines entirely. Exceptions to the general rule of removal consist of abandonment in place if: the line is excessively deep (generally greater than seven feet of cover), the removal of the line will entail excessive or expensive removal of surface improvements, the line to be removed is known to pass through a contaminated area, (this alone may not be a basis for leaving the line in place) or the removal will cause other inconvenience or excessive expense to the port. Lines abandoned in place shall be cleaned and mudjacked. (Mudjacking is not required if line is six-inches in diameter or less.) Backflow preventor: Placement of backflow preventors shall comply with City of Long Beach Water Department standards. Connection to Fire Hydrant Laterals: Generally, connection to a fire hydrant lateral should be avoided. If connection must be made the fire hydrant lateral must be a minimum of eight-inch diameter. Fire Hydrant Assemblies: For new waterline improvements where fire hydrants are to be placed the fire hydrant, and valving, in the line to the mainline are to be bid as one, normally called a fire hydrant assembly. This assembly shall include any gate valves required in the run from the mainline in addition to the water valves adjacent to the fire hydrant. Sewer Forced mains: The maximum run for two-inch diameter forced main is 100 feet. Any use of forced main less than four-inches in diameter must have specific approval of the Chief Harbor Engineer. The maximum run for four-inch force main is unlimited provided clean-outs are installed at 100 feet on center. ABS is approved by the Maintenance Division for sewer forced mains.

5 Sewer Forced main clean outs: Sewer forced mains shall have clean outs installed at spacing adequate to conform to the cleaning method and apparatus in use by the Maintenance Division or at locations which may be a clogging point ( such as 90 degree bends). These clean outs shall be brought to grade where appropriate. Coordination and approval by the Maintenance Division shall be obtained prior to final design of the forced main, clean-out, and/or lift station. Guard post size: Guard posts are a minimum of eight inches in diameter unless otherwise approved by the Chief Harbor Engineer. Guard post standards: All facilities vulnerable to damage from heavy equipment, e.g. staffed guard booths and electrical equipment, should be protected by guard posts. Guard post installations around light poles or substations in container terminals shall comply with the latest Port standard for spacing, placement, and interconnection. Note that SCE have their own standards for guard post spacing which must be followed around their facilities. Guard posts shall not be placed to protect fire hydrants on streets. Use warning signs as breakaway posts. Meters: Water meters shall be placed and to the size approved by the Maintenance Division and the City of Long Beach Water Department. Rainwater diverter: For wash down facilities where the collection point of the facility is exposed to rainwater runoff, a rainwater diverter must be installed to Planning Division, LA County Sanitation, and Regional Water Quality approval. This diverter would allow the diversion of the waste flow, normally to the sewer, to be diverted to the storm drain after some amount of rainfall (usually one-tenth of an inch). The reset must be automated. Safety yellow: Safety yellow is a specific paint color used to paint guard posts, barriers, and other objects which need to made apparent for safety purposes. Valves in catch basins: Due to the number and location of oil facilities within the Port and the possibility of an oil spill which will tend to run to catch basin locations, many catch basins in the Port are fitted with butterfly valves which are normally kept closed to stop oil spills from reaching the water. These valves are normally controlled by TOPKO who open them on forecasts of rain. Standards are available for the installation of these catch basin valves through the Department of Oil Properties.

6 Water line material: Water line material shall be as approved by the City of Long Beach Water Department or as approved by the Chief Harbor Engineer. Currently ductile iron is the only approved material by the Water Department. ABS has been approved for use within the Port. Water Injection lines: Lines used to replace extracted oil with water. Due to the high pressure of 1400 psi, all water injection lines shall be considered as potential safety hazard to workers. Trench below Groundwater table: For trenches placed below the groundwater table in contaminated or possible future contaminated areas, the granular trench bedding shall be sealed with concrete slurry at approximate 600 feet on center to prevent the movement of contaminated groundwater through the trench bedding. Storm Drain pipe placed below Groundwater table: All the below groundwater table storm drain pipe shall have rubber gasket joints to prevent infiltration of groundwater. ROADS/PAVING Geometric standards: In addition to those recognized standards of CalTrans and AASHTO designers must also recognize the large number of truck movements within the Port and design accordingly. Roads shall normally be designed to accommodate the STAA vehicle. Guide signs: The intent, placement, color, and shape of guide signs within the Port are to be in accordance with standards of the Port Traffic Engineer. They shall be consistent with CalTrans guidelines and the existing unique Port Guide Sign Program. Landscape master plan: All development and improvements within the Port shall include provisions for landscaping in accordance with the Port s Landscape Master Plan. Any landscape plan shall be approved by the Planning Division and the Chief Harbor Engineer. Trees whose diameter could grow to larger than four-inches should not be planted closer than nine feet to the edge of the travel way. Paving section: The paving section (consisting subbase, base, & surface material) shall be designed for the loads and repetitions anticipated over the life of the intended section. A pavement design manual is being developed which should be used as a basis of design. Normally an asphalt surface material is used for the majority of paving. For particularly high point

7 loads or high repetitive loads the use of concrete is used. Special asphalt (like Trinidad Lake Asphalt) or mixes (like Stone Mastic) have been used for anti-rutting purposes. Bridges and road sections shall be designed to accommodate the HS25 design vehicle. Traffic Control Plan: Any construction work on Port roadways must be described in a Traffic Control Plan that is approved by the Port Traffic Engineer. Consultants shall prepare, for the eventual use by the contractor, base maps that can be used to locate construction traffic signs removed from the actual work site. Slope of pavement: Slopes should not exceed one percent in container areas. Vertical clearance: During the design phase of any major roadway reconstruction project, try to achieve the required vertical clearance of 16-6 under an overpass bridge. Striping - paint vs. thermal plastic: Paint is the preferred medium for striping within terminals and thermal plastic is preferred on the streets. Review conditions and recommendations for medium to be used with Traffic Engineering section. Truck traffic: percent of the traffic in the Port is truck traffic. This fact must be considered in all aspects of design and operations of roadways within the Port. Truck turning radius: Intersections, curb returns, and lane widths on curved streets must consider truck turning radii for their design. Sidewalk width: Sidewalk width shall be wide enough for both utility poles and wheelchairs. The setback for a signal pole is 2-6, and the minimum clear width for a wheelchair is three feet. A signal pole may have a base plate as large as two feet square. Signing: Signing within terminals shall avoid using the colors yellow and red except for warning and STOP, YIELD, and WRONG WAY signs. STRUCTURES/BUILDINGS Bollards: Bollards are made of cast steel molded over a standard pattern. A standard Bollard pattern is available from the Maintenance Division to use in fabricating new bollards. This information can be placed in the specifications to inform the contractor of its availability and present safeguards and proper return of the pattern after use. The pattern is good for two or

8 three successive wharf contracts and then need to be rebuilt. The pattern needs to be inspected after each use and if a new pattern needs to be built that should be made part of the next wharf contract. Bridge wave: A standard exists for the wave graphic which is to appear on the outside of any new concrete bridge placed in the Port. The wave shall break in the direction of traffic (i.e., the identical form liner can be used on both sides). Building signage: Buildings should each be designated by a letter mounted near the top of the building (and on the roof for Police Department use) as approved by Traffic Engineering section, the Fire Department, and City Zoning Code. Bullrail: The wharf face of any wharf shall be fitted with a bullrail of approximately 10-inches high and 12-inches wide to provide a barrier for vehicles Coatings & testing: Painting and/or coating of any structure shall be specified to be tested by an accepted testing method for thickness measurement and by a qualified inspector. Corrosion inhibitors: The Port has used Calcium Nitrite additives in concrete to provide a corrosion inhibitor. A formula is now placed in the specifications based on life of the structure, depth of cover of the steel reinforcing, concrete mix, and proposed additive. This formula will determine the adaptability of the additive to the circumstances and determine the dosage rate required. Demolition standards: Demolition of structures shall include the removal of the foundations of that structure, as defined by the engineer. Light pole foundations shall be removed to a minimum of three feet below the ground surface. Fence pole foundations shall be removed as part of fence demolition or relocations. Fencing security standards: Standard fencing on the perimeter of a terminal must be fitted with a continuous ¾-inch thick steel wire rope running longitudinally at approximately three feet above the ground surface Fencing standards - Galvanized, U. S. Customs: The standard perimeter fence for any terminal shall conform to U. S. Customs fence of eight-feet high with top rail and three strands of barbed

9 wire on the top. All must be galvanized. U.S.Customs standards require paving to be underlying the fence for a minimum of two feet beyond the fence line. Keying: Keying of a structure is controlled in the building specification by calling for Sargent 8100 series locks. Marine concrete standards: Concrete in the Port shall be designed to incorporate the hazards of weather and moisture encountered in the marine environment. It is important to maintain a water/cement ratio at 0.40 and a minimum cover over the reinforcing steel of 3. If the structure is over or near the water a special evaluation should be done to check chloride infiltration. This evaluation must consider the expected life of the structure, the minimum cover over the steel, the rate of chloride attack, and, the protection afforded by any corrosion inhibitor additive used. Currently the Port utilizes DCI by W.R.Grace which is a calcium nitrite product. RAILROAD See Port railroad standards No rubber crossings: Rubber crossings are discouraged inside terminal areas and must be specially approved if to be used on roadways within the Port. Concrete crossings are encouraged. Relay rail: Generally relay rail is acceptable for use on new rail installations. Safety/warning: Special caution must be observed when working adjacent or within 50 feet of a railroad track. Special training is required for work within four feet of the centerline of the track..
