3. Labour, materials, equipment schemes
(1) workforce use plan: rationalize the work schedule of the construction staff in accordance with the construction schedule and workload to ensure adequate labour capacity during the construction process
(2) material supply plan: preparation of an advance material supply plan to ensure the timely delivery of materials in accordance with the construction drawings and construction programme
(3) plan for the use of construction machinery: rational arrangements for the use of construction machinery in accordance with construction requirements to ensure the smooth running of construction。
This section provides a detailed description of the construction design, including the project management structure, the construction workforce configuration and the workforce, materials and equipment plan. The content is in line with the actual conditions of construction and ensures that the skills, management, construction skills and resource allocation in the construction process are adequately safeguarded。
Iii. Construction methods and technical measures
Construction methodology
(1) exterior glazing: the use of specialized cleaning equipment, such as robots, guns etc., in conjunction with cleaning agents. During the cleaning process, the glass surface is examined in detail and the stains are cleaned in a targeted manner. After the clean-up is completed, it is washed with water to ensure that the glass surface is clean and transparent。
(2) maintenance of the exterior wall: refurbishment of the wall with appropriate maintenance materials, including stains, damage, etc. When the surface of the wall is removed, the damage is removed, then polished, patched, and the corresponding coating is finally painted。
(3) refurbishment of the exterior wall coating: refurbishment of the decorated and damaged areas, first to remove the decorated parts, then to grind, then to paint, and finally to paint. In the coating restoration process, attention is paid to parameters such as the uniformity of the coating, saturation and the temperature of construction。
2. Technical measures
(1) high-altitude operational safety: the construction of safety shields and the wearing of protective equipment such as seat belts, helmets, etc. By the construction personnel. High-altitude operational equipment is regularly inspected and maintained to ensure its safety and reliability。
(2) construction quality control: construction is carried out in strict compliance with the construction drawings and the construction programme to ensure the quality of construction. Quality testing of critical elements of the construction process, such as paint varieties, coating thickness, etc。
(3) construction protection of the environment: during the construction process, effective measures are taken to reduce the impact on the surrounding environment, such as containment, dusting, etc. The waste generated from construction is properly treated to avoid contamination of the environment。
(4) seasonal construction measures: the implementation of appropriate measures to ensure the smooth running of the work in response to climatic conditions in different seasons. For example, construction time is rationalized to avoid high-temperature periods during high summer temperatures, and materials and equipment suitable for low-temperature construction are selected during winter temperatures。
This section details construction methods and technical measures, including outside wall glass cleaning, exterior wall maintenance and outer wall coating repairs, as well as technical measures such as high-altitude operational safety, construction quality control, construction environmental protection and seasonal construction measures. Ensuring adequate safety, quality and environmental protection during construction。
Iv. Payment of the place of the station
1. General floor layout of the construction site
(1) temporary facilities: temporary facilities such as construction site offices, lounges and temporary toilets to ensure that the living needs of the construction staff are met
(2) roads: planning of internal roads at the construction site to ensure smooth movement of construction vehicles and personnel
(3) material dumps: rational planning of material stacking areas to ensure that materials are classified, stacked, easily managed and used
(4) processing sites: appropriate processing sites, such as paint transfer areas, maintenance operating areas, etc., according to construction needs
(5) safety and protection areas: to ensure the safety of the construction site by setting up safety and protection areas, including security warning signs, guard posts, etc。
2. Phased floor layout
In accordance with the schedule of construction, a phased adjustment and optimization of the floor layout of the construction site will be undertaken to ensure the smooth running of construction. For example, during the glass cleaning phase, emphasis is placed on cleaning equipment, material storage areas; during the wall repair phase, emphasis is placed on maintenance operating areas, material storage areas; during the coating restoration phase, emphasis is placed on coating redeployment areas, coating construction areas, etc。
This component provides, inter alia, detailed planning of the floor layout at the construction site, including the overall floor layout at the construction site and the phased floor layout. The content is in line with the actual construction conditions and ensures order, security and efficiency at the construction site。
