IX Methodology
Fabrication, supply, and installation of SS handrails comprising Ø 50.8 x 1.5mm thickness brushed stainless steel pipe as railings and Ø 20mm SS rod as connector fixed to brackets and covered with SS base cover as per the following steps:
Shop Drawings
Shop Drawings will be prepared according to the IFC Drawings and will include all the required details such as key plan, plan, elevation, section, and fixing detail. Shop drawings will show fabricated assembly details for the stainless steel handrail. The actual dimension for the fabrication is based on the dimensions in the approved shop drawings.
Mock-up and Sample
Based on the final approved shop drawings, a site survey will be conducted to cover the overall dimensions & shape of the structure will be cross-checked with the approved drawings. All the sections & levels will be checked with the final approved drawings. The basic reference level of the structure will be followed for the works. Upon confirmation, a mock-up will be installed on the site for inspection, after approval same quality will be maintained for the entire installation.
Fabrication
As per the site, readiness measurements will be taken, and fabrication will be done in the concerned factory. All the welding for the joints will be done on the site as per site conditions and approved shop drawings.
The fabricated units are properly tagged and labeled for identification at the storage area in the factory as well as at the site. Fabrication is carried out based on the tolerance permissible.
Deliveries, Storage, and Handling
Stainless steel pipes are transported in trucks in a vertically stacked position resting on a soft base over the wooden block and tied with proper safety ropes and protection to avoid any damage in transit, unloading of items will be carried out and will be stored in the allocated areas.
Unloaded stainless steel pipes will be covered and proper barriers will be kept protected from damage.
Handling of each unit is carried out with care to avoid scratching, denting, and other possible damages.
Installation Works
The execution/erection work shall be as per approved shop drawings in accordance with project specifications.
All kinds of handrails mentioned in the scope of work are to be installed, finished and handed over to the consultant/client within limits of tolerances and in compliance with the erection sequence.
Site Survey for Confirmation Access/Lifting Arrangements
Prior to starting installation work, a site survey was arranged for the specific area of the project with the coordination of the site engineer, HSE Department, and logistics department.
All the site provisions under the part of each section have been checked and inspected by the surveyor to make sure that all are in proper working conditions and as well as scheduled in respect of time availability associated with other ongoing activities.
The access area selected by the HSE and Logistics is to be used for shifting the material from site storage to the fixing place. The handrails shifted from site storage to the right structure/building using the selected access by HSE and Logistics, then will be lifted by crane or manually from the ground to the fixing place at the points provided at the factory.
Level Marking on Site
Structural frames/surfaces are to be checked for their tolerance level. Alignment is required for the exterior face of the panel and proper marking with string lines is to be done prior to the start of installations.
The level marking on each elevation shall be given as per their structural and approved shop drawings. Any discrepancy beyond tolerance is to be brought to the notice of the site construction for rectification.
Erection Procedure
Installations are carried out in accordance with the erection drawing and site conditions. All fabricated units are brought and placed at their respective locations manually or via mechanical means. Brackets are fixed to the existing slabs.
The pre-fabricated railings are welded to the bracket. A stainless steel base cover is used to cover the bracket areas to cover the welding areas.
Cutting machines and cutting wheels are used to cut the stainless steel materials on site.
Water levels are used to check the alignment and level. After polishing it will be covered/wrapped with a polythene sheet or similar, securely taped to protect the handrail.
Quality Assurance/ Quality Control
Significant stages of work shall be ensured by the Project Engineer, Site Engineer, and Quality Control Engineer in compliance with the specified requirements of the contract documents including:
- Use of approved shop drawings and approved materials.
- Vertical and alignment of walls will be checked while plastering.
- Mixing of mortar will be done under the supervision of foremen.
- Cleaning out debris and dust.
- Quality Engineers shall monitor all these stages and an Inspection Request (IR) shall be submitted for consultant approval of executed works for approval. Prior to calling the Consultant’s Engineer, a joint inspection will be carried out with the contractor’s QC Engineer for the satisfaction of the work to make sure in compliance with Project specifications.
- Welder’s valid certificates & list of welders.
