Building specifications and plan

Discuss about the Sustainable Approach Towards The Construction.

l be used as the framework to ensure that public health, the traffic, the environment and the neighboring structures are not affected by the demolition activities.

The demolition plan has been developed after comprehensive analysis of the building's specifications and all the demolition regulations. This detailed plan is designed to be approved by the relevant authorities and satisfy the client before the actual demolition takes place at the site.

The building is bound by Rutledge Street, Trelawney Street and Rowe Street with admittance to all facades. The pictures attached show the representation of the building to be demolished from different viewing sides. The specific sites to be demolished are shown in the plan drawing of the building below.

The buildings found around the site to be demolished have the heights ranging from 10-15 m above the levels of the existing streets. There are also tall electrical distribution systems at 1 m from the building to be demolished. All around the building there are other buildings within 20 mm except on the sides adjacent to the streets.

Description of the Buildings to be demolished

The building to be demolished is generally constructed with load bearing masonry walls except the existing concrete car park with different levels. The roofs of the building are either timber framed steel framed or metal roofs. The building to be demolished is a one story structure. The building is generally constructed on a concrete slab on the ground with still reinforcements to provide more support. The building has fabricated glass windows and metallic and wooden doors. The building consists of a series of bored rigid concrete piles. The building also comprises of plasterboard, tile and terrazzo floors and glass skylights. Below is the plan of the building to be demolished.

An A class hoarding should be constructed around the perimeter of the construction site before the demolition process begins. In order to prevent the risk of falling objects a 8 class hoarding should also be provided. The class B hoarding is to be established to the sides adjacent to the street and foot paths. This would be on the western boundary and the Rutledge Street frontage.

In addition to the A and B class hoarding, scaffolding should be erected in the frontages where materials could fall from a height excess of 4 meters. In order to enclose debris and the dust that comes from the site, the scaffolding should be clade with shade cloth and chain wire. Dust control measures will be applied during the demolition to minimalize the dust from spreading to the surrounding structures. A senior representative of the demolition contractor should be at the site at all times to ensure that the safety guidelines and requirements are adhered to.

It is not necessary to establish an exclusion zone since all the demolition debris is going to be contained within the demolition boundary[2].  In the event an acceptable risk rises in the process of demolition, the contractor will prepare a detailed Job Safety Analysis and Safety Work Method Statement to inaugurate an exclusion zone.

Description of buildings to be demolished

All the traffic will be held within the boundary during the demolition process. The site will always be closed to pedestrian traffic and security personnel should be deployed to man the pedestrian traffic in and out of the demolition site.

The following equipment will be required for demolition of this building.

-1- Caterpillar 350 High Reach Excavator with pulverizer and shear attachments

-1- Caterpillar 325 with shear, hammer and grapple attachment

-1- Komatsu PC300 Excavator with grapple and sheer attachment

-2-JLG 120' man lifts

-1-scissor lift

-Connex box for storage

- 2 pickup trucks

-1- 80-ton conventional cranes

-dust control equipment

-temporary lighting

-trash pump

-franc tank

-generator

-Rigging equipment

-1 decontamination trailer

- Waste containers

All the equipment mobilization notification should be made prior to the expected date of arrival to enable the contractor to do the inspection. The delivery of heavy equipment should be coordinated well in accordance with the regulations[3]. Cranes and excavators will be assembled on site but strictly according to the manufacturer specifications. They will then be inspected after assembling to ensure that they are functioning in accordance with the design and ensure that all safety mechanisms have been installed.  The contractor should ensure that the equipment is operated by experienced, competent and properly trained employees.

After pre-mobilization planning and submission of all the requirements has been done, a pre-demolition inspection should be done and a documentation of the existing site condition be prepared before any on-site work commences.  Site mobilization will then follow after the pre-demolition inspection to understand the current configuration of the site such as the security requirements, site hazards and the residual liquids. The job site turnover requires adequate personnel and time.

The demolition contractor will use the following personnel in the demolition process

Project Oversight: - operations superintendent - Mr. James Smith

Site safety and health manager (SSHO) – Mr. John Kennedy

Decontamination and demolition (D & D) team: - 2 labor foremen 6 laborers 5 operators

Hazard mitigation team: - 1 supervisor 9 laborers

All the personnel should ensure they wear protective gear in accordance with the rules and regulations. They should also familiarize with the site and have information of the immediate environment surrounding the site. The hazard mitigation team should be made up of experienced and skilled technicians with a minimum of 10 years in the construction industry. The overall demolition work will be accomplished by the decontamination and demolition team and the hazard mitigation team in a safe and systematic progression with the close coordination of the project oversight team. The SSHO will ensure that there is a "zero tolerance" safety culture and ensure that he assess the potential hazard for every procedure at the site.

Geophysical survey will be performed by the demolition contractor to locate all the utility lines within the site perimeter and ensure that all the utilities to the building have been terminated. The site conditions will dictate how the isolation of the building from the utilities will be performed. The Dig Safe of New York should be utilized before the actual demolition observation requests. All the identified utilities should be marked clearly with markings that will remain visible during demolition.  Underground utilities (such as sewer, gas, water, electric, or telephone) that have been identified but not terminated should be drawn in a drawing that is to be presented to the site oversight team.

Safety measures during demolition

A professional engineer should be contacted by the contractor to evaluate the structural integrity of the building.  The evaluation should include details of the building's current condition and a recommended approach for building demolition. The evaluation should also indicate the various measures to be undertaken to prevent the unplanned collapse of the building.  The engineer will perform the assessment in accordance with

SEI/ASCE 11-99 Guidelines for Structural Assessment of Existing Buildings

29 CFR 1926.850 – Safety and Health Regulations for Construction, Preparatory Operations

ANSI AI – 6 – Safety Requirements for Demolition Operations

Radiological surveys, analysis, sampling and historical knowledge will be used as outlined in the Sampling and Analysis plan to pinpoint hazardous and radiological materials that may be encountered during the demolition process. The hazardous materials should be identified and quantified. These materials include lead, fluorescent light fixtures, thermostats, light ballasts, mercury/sodium vapor, ACM and capacitors[4]. Once the wastes and the hazardous materials have been identified they should be removed or stabilized and they should be packaged separately from other building debris.

The proper disposal requirements will then be identified using the process knowledge and analysis of the samples. The materials will be transported away from the building to disposal site prior to the demolition of the building. The disposal and the transportation of these materials should be done in accordance with the local regulations and guidelines.

A licensed asbestos inspector will perform a pre-demolition asbestos survey in both the exterior and interior of the building with the roof included. The goal of the survey is to correlate, evaluate and quantify all the materials containing asbestos. The survey will then provide the guidance for the removal of these materials prior to the actual demolition.  Any material with a layer that contains greater than 1% asbestos will be considered as asbestos-containing material (ACM).

After all the pre-demolition activities have been performed, the contractor will then go ahead with the demolition of the building.

Dust control mechanisms will be established during the actual demolition of the building to prevent the spread of contamination and also maintain the particulate level at the permissible exposure level (PEL) as specified in 29 CFR 1926. 555.  The dust control measure should consist of dust suppression measures as well as ambient air monitoring to substantiate the realization of dust suppression.  Below is a summary of the dust control to be implemented during the demolition.

Applying a water spray during wreckages/ waste handling and to unpaved vehicle access routes at the site as required.

Wetting demolition equipment and active demolition area as required.

Keeping the speed of vehicles below 10 miles per hour on unpaved surfaces

Covering debris/ waste piles

Hauling wastes /debris leaving the site in closed or covered containers

A spray pump and nozzle system should be applied in suppressing fugitive dust in the attempt to prevent overly wet conditions, conserve water and avoid runoff and ponding. The water used for dust suppression will be obtained from the on-site water source. Demolition activities with the potential of causing dust such as transportation of debris, building demolition, and piles of debris and loading of waste should be closely monitored for radioactivity and dust particulate in accordance with the procedures described.

Required equipment for demolition

The demolition of the building structure will start by removing the low rise portion of the structure attached to the main high rise section. Cat 345 with a shear attachment will be used to perform the removal procedure. Where possible, the low rise additions will be removed and size reduced from within the structure's footprint. The demolition the will proceed from the top to the bottom bay by bay through the building. The cat 345 operators will shear the roof trusses attached to the building with the close supervision of onsite superintendent and Mr John Kennedy. The roof truss on the opposite end along the perimeter of the building will then be sheared and the removed beam to be lowered. All the roofing should be dropped alongside the truss segments. The trusses and the debris that has been generated will be allowed to accumulate on the slab of the building. All the horizontal beams of the building will then be removed by shear as well as all the vertical columns which should be sheared at the bottom. Approved torch cutting procedures will be used to remove bolts used to attach the structural steel columns to the concrete slab prior to the demolition. Controlled free fall of the intermediate platforms suspended from the structure's main framework will occur as the demolition progresses

High sections of the building will be demolished using cat 350 UHD track hole attached with a shearer. The high reach operator will be in charge of the safe dismantlement of the upper section of the building. The first roof beam will be cut at the end just inside the column line then the beam will be bent before being freed on the opposite side. The beam will be lowered and undergo size reduction. The generated debris will be allowed to collect on the flow below and the process will be performed on the lower floor too. Below is a graphical illustration of the demolition.

All the debris generated will be removed from the demolition site. The waste will be transported to the appropriate landfill or recycling of steel. After removing all the waste, all the temporary facilities will also be dismantled and disposed of properly. A post-construction radiological survey of the surface slab and the surrounding area will be performed. Site restoration will then follow through restoring disturbed areas to the pre-demolition condition.
