Miller Environmental, Inc. (MEI) has prepared this Demolition and Removal Plan, hereafter referred to as the "Work Plan", for the purpose of providing a detailed description of demolition and removal procedures, which MEI will be implementing during the on-site activities at the California State University Long Beach - Peterson Hall #3 Building Demolition Project.
Peterson Hall #3 is located on the campus of the California University State Long Beach (CSULB), in Long Beach, CA 90840. The Peterson Hall facility is located on approximately 3 acres of land owned by the Regents of the University of California. The structure consists of a 105,000 SF three story concrete and partial brick building with associated additional structures such as a single story brick lecture hall, two green houses, a former animal house, stair towers, a 3 level bridge connecting the MLSC Building and various site concrete and asphalt within the work areas. The work is surrounded by the CSULB.
The work covered under this Work Plan will be conducted in a sequential manner, with some activities being conducted concurrently with others. Demolition work will be performed in accordance with Cal OSHA, SCAQMD 403, the requirements of Cal State Long Beach and Hunt Construction. Depending upon site and other unknown conditions, MEI's general sequence of demolition activities may require alteration at any given time. A summary of the general sequence for the work activities is outlined as follows:
MEI considers safety and the prevention of accidents an integral part of its operation. Under Federal, State and local laws, MEI is responsible to provide a safe working environment, to protect life, health and safety of its employees and subcontractor's personnel. Although providing safe working conditions is primarily a management responsibility, safety and accident prevention can be accomplished only through coordinated efforts of all employees and subcontractor personnel. It is the policy of MEI for this project as with all of our projects, that if the task or service being undertaken cannot be done safely, that work is to be stopped until proper controls can be established.
MEI will hold daily tailgate meetings for its employees prior to work commencement. Additionally, MEI will require that subcontractors be required to hold similar daily tailgate meetings covering their respective portion of the work. These meetings are designed to discuss the projected work schedule and prepare each worker for any potential hazards associated with the work activities. A copy of the daily or weekly safety meeting logs will be maintained onsite at all times. All personnel attending the safety meeting will be required to sign the safety-meeting log upon completion of the tailgate safety meeting. During the tailgate meetings, personnel will be reminded of site conditions and are encouraged to participate with health and safety concerns.
At the conclusion of the project copies of all daily activities will be presented in a final report to Hunt Construction for distribution to relevant parties.
Prior to commencement of building demolition, a thorough walk through and evaluation of the building will be conducted to confirm that all appropriate measures have been completed to ensure that the area is ready for commencement of demolition activities. A Pre-Demolition Survey will be completed and filed in the MEI field office or with the MEI site manager. A copy of the Pre-Demolition survey will be provided to Hunt Construction for as needed distribution to the Team.
In general, the tasks will include a wide variety of procedures. The most important aspect in the development of these procedures will be the safe conduct of the work. MEI's procedures will limit the use of labor to the most controlled and safe conditions and rely upon mechanized means of removal wherever possible. 100,000 lb.excavators equipped with concrete breakers, concrete munchers, grapples, and other modern hydraulic demolition tools and attachments will be utilized. Wherever possible, large structures will be removed to ground level using mechanized means. Subsequent sizing of scrap materials such as steel and rebar and other material processing activities will take place at grade level, hauled off site and recycled accordingly.
General building/structure demolition will be conducted in a manner that does not interfere with or encroach upon the existing surrounding pedestrian and vehicular traffic during normal activities. Hunt Construction, Inc. has provided fencing around the project site and Miller Environmental, Inc. will work within the confines of the site fencing whenever possible. However, depending upon site and structure conditions, alternative methods of demolition and alternative types of equipment may be used to ensure the safest and most efficient means of operation. This may involve modification of the site fencing form time to time in order to complete the demolition activities. This will always be coordinated with Hunt in advance.
RFI's will be issues as needed if questions or scope issues arise during the course of the demolition activities. Field activities related to any RFI's will not occur until an appropriate answer has been provided.
MEI will perform salvage operations in accessible areas where the power has been isolated by Hunt while the soft demolition and remaining clean up activities are going on. MEI will use Bobcat skid steer loaders and hand labor to remove all soft debris that is not easily separated from the concrete material. This includes removal of roofing, ceilings, HVAC ducts, insulation, plaster partition walls, lights and all other building components that will not be recycled. After much of the soft debris is removed MEI will commence the abatement activities and then resume with additional salvage and interior demolition until the building is cleaned out of all soft demolition debris.
MEI will utilize excavators and track loaders equipped with special demolition attachments (i.e. hydraulic breakers, concrete munchers, hydraulic shears, and grapples) to demolish the existing buildings. The use of MEI's excavators, which can reach up to 36 feet, greatly reduces the need for demolition personnel to work at elevated heights, increases the efficiency of the demolition process, and allows a more controlled operation than conventional crane and ball wrecking procedure. The building will be demolished by breaking the roof, walls, and floors inward and allowing the concrete to fall into the interior footprint of the building. The excavators will progress in an East to West fashion and continue the breaking in a top-down manner. As demolition progresses, concrete and steel debris will be cleared with excavators and relocated to the designated debris pile locations. The concrete debris will be sized into manageable pieces and hauled off site to a recycler for crushing into road base.
Demolition of the existing buildings will begin with the buildings located in the Southern part of the project. These buildings include the 2 green houses, the animal house and other misc. structures in the current loading dock area. The three 3 story concrete framed structure identified as Peterson Hall #3 will begin with the demolition of the 3 level stair tower that connects to Microbiology once the tower is shored and all utilities are cut and capped by Hunt. This will insure that no damage will occur to the Microbiology Building (MIC). Demolition will then proceed on Peterson Hall #3 working from east to west along the long wing of the building. As we proceed west we will then demolish the bridge that connects PH 3 to the molecular and Life Science Building (MLSC). This will be completed with an excavator and shear and possibly a crane if needed.
Miller Environmental, Inc. will continue the demolition of PH 3 on the T- Wing part of the building that runs in a north/ south direction. By removing this section of the building we will effectively create a very large work area for trucks to maneuver. The work in this area will also involve the separation of PH 3 from PH 2 at the expansion joint. PH 2 is scheduled to remain intact.
Miller Environmental, Inc. will continue demolition activities to the west by demolishing the existing concrete and brick Science Lecture Hall Building (SLH). Once the SLH is complete we will complete the western section of PH 3.
The green waste will be demolished as we encounter it and all of the flatwork will be completed towards the end of the project.
MEI will utilize excavators with demolition attachments (i.e. grapples, shears, and breakers) and track loaders to demolish these buildings. Demolition will begin from the top working down and from one end of the building working towards the other end. Excavators and loaders will systematically demolish the building structure and process the demolition debris. Demolition debris will be segregated and stockpiled for proper disposition. Slabs and footings will be broken in place, processed and hauled off site for recycling.
Demolition of site asphalt, concrete walk areas and green waste will be handled after the main building is demolished. We will leave as much of the existing A/C and concrete as possible in order to limit mud and other runoff.
Concrete demolition will consist primarily of removal of building slabs, building walls, columns and footings. Miller Environmental, Inc. will use excavators to demolish the concrete down to slab or adjacent grade elevation. Track loaders may assist with debris removal, processing, stockpiling and loading.
During demolition of the existing building structure, MEI will process the demolition debris to recycle as much metal material as possible. Structural steel framing, metal roofing and siding, reinforcing steel in concrete, copper tubing, electrical cable, electrical gear, controls etc., will be separated prior to the demolition as much as possible. All metal materials recycled as part of this project will be documented with weight tickets which will be provided with each application for payment. These materials will be hauled to the following recycling facilities: Each of these facilities is well aware of the potential lead on various metal components. A letter acknowledging this will be provided from the facility.
Clean concrete debris from the demolition activities will be stockpiled and then shipped off for re-cycling. If Hunt wishes to have any material crushed for re-use on site at a later date then please discuss this with us now. MEI if negotiated can mobilize a portable crusher to crush the concrete material to Class II road base. We do not see that as a viable open for this particular project. All concrete and asphalt that is hauled off the project site will be recycled and tickets will be provided with each application for payment. This type of recycling does not get weighed but each end dump load we haul off is equivalent to 20 tons. The owner will be provided trucking tickets that show the number of loads.
As of this writing all concrete material will be shipped to the Ed Mason Grading facility located at 1245 East Arrow Highway Pit #2 Irwindale, CA 91706 or Loveco located at 23320 South Alameda Carson, CA. We are attempting to locate a plot of land in the immediate area of the project site so we can deliver, process and crush at the off site location. We will keep Hunt informed of our progress on this issue.
All demolition debris that will not be recycled by MEI will be loaded into semi-end dumps and hauled to a disposal facility for further recycling or landfill. The end dumps will be covered prior to leaving the site. The requirement of this contract in accordance with California Assembly Bill 75 is that 50% by weight of the construction and demolition debris be diverted form landfills by a combination of recycling and re-use. This includes interior soft debris (i.e. drywall, plaster, ceiling tiles, roofing material, etc.). Demolition debris may be hauled to the following disposal facilities:
Dust control will be considered an important part of the overall project. MEI will utilize a water trucks and/or fire hose attached to a local hydrant during demolition operations. MEI will direct a localized fine water spray to the source of demolition activities, as required, thereby reducing airborne dust particles. To minimize the run-off of water, the water supply will be used only when necessary. A proper backflow devise will be installed at the hydrant locations we utilize.
Miller Environmental, Inc. will maintain any SWPPP measures that have been installed by Hunt Construction as well as maintain the requirements of the Notice of Intent once filed. Once Miller Environmental, Inc.'s work is completed future contractors will maintain the SWPPP measures.
