Installation Construction Plan and Technical Methods for Solar-Powered Street Lamps

I. Construction Preparation
1. Personnel Preparation
A project manager responsibility system is implemented, and a project management team is established. Installation work is overseen and coordinated by the project management team.
The project manager shall, in accordance with the requirements of the construction organization plan, convene the relevant engineering and technical personnel to coordinate and implement the work for this contract section.
The specific tasks involved in the construction project.
Prior to entering the site, the project management team organized training for the technical and managerial personnel, as well as the crew leaders, on technical quality and safety.
Conduct a comprehensive briefing to clearly define each individual’s tasks and job responsibilities, and implement a post‑responsibility system.
2. Technical Preparation
Prior to the commencement of the project, under the leadership of the project manager, the relevant technical personnel of the project department were convened to carefully review the drawings and identify any ambiguities.
Any unclear issues shall be promptly compiled and communicated to the owner and the design team for timely resolution.
Organize a three-tier technical briefing: the first tier is conducted by the project manager, with engineering department technical personnel presenting the design scope and design intent.
In addition, all relevant indicators are communicated to the project management team, and any ambiguities in the drawings are clarified; the second-level briefing is conducted by the project manager of this construction project.
Under the guidance of the technical director, the key construction management personnel are organized to study the “Construction Organization Plan,” thereby clarifying quality objectives and technical specifications.
Standards for compliance and quality inspection, as well as an analysis of potential issues in the construction schedule and their corresponding solutions; the third level is undertaken by the project’s technical personnel.
The project manager and the site supervisor shall brief the construction workers, and for critical processes, they must carefully assess the technical feasibility of implementation and ensure its practicality.
Implementation method: Mobilize employees at the ideological level to attach great importance to this project, thereby facilitating its high-quality completion.
3. On-site Preparation
To ensure that all construction processes on the job site proceed in an orderly and well‑coordinated manner, our company provides prefabricated offices on site,
Auxiliary facilities and storage warehouses shall be made available to the Contractor for use, provided that such use does not interfere with the operations of others, or shall be provided on the construction site or in nearby buildings.
Set up on-site offices, auxiliary facilities, and storage warehouses. Ensure the construction site is clean and well-organized, with unobstructed access roads, and that all trades carry out their work in an orderly manner.
Smoothly, without mutual interference or restraint.
Prior to commencement of work, the project team shall coordinate with the owner to install temporary water and power supply systems, ensuring that the construction site meets the “seven connections and one leveling” requirements.
The project can proceed smoothly.
Upon entering the site, immediately conduct a field re‑survey of the design‑provided elevation benchmarks, followed by site grading and connection to the construction water supply.
Power supply, erection of construction power lines, and installation of construction water pipelines.

II. Construction Procedures for Streetlight Installation
Surveying and layout, positioning — removal and restoration of the pavement — earthwork excavation — concrete pouring and installation of embedded conduits — backfilling with sand and compaction — luminaire installation — solar panel installation — hoisting — battery installation — commissioning and acceptance.

III. Construction Method for Streetlight Installation
1. Surveying, layout, and positioning
(1) Familiarize yourself with and review the drawings.
Familiarize yourself with the site plan and design specifications, and gain an understanding of the project’s location, site boundaries, surrounding environment, and nearby buildings.
The interrelationships among buildings and roads, as well as the site’s topography, etc.
When reviewing the drawings, the primary focus is on verifying the dimensions of each axis and summing these dimensions to check the overall dimensions of the structure.
Verify that the dimensions on all types of drawings are consistent and that the elevations match.
Based on the pole spacing, coordinates, and benchmark points provided by the tendering party, the pole foundations shall be constructed in strict accordance with the design construction drawings.
Foundation positioning, installation of embedded pipes, and elevation transfer.
(2) Surveying and Layout Plan
When arranging the site’s general layout, coordination with all relevant parties is essential, and appropriate locations must be selected to ensure that the primary elements of the control network…
The location can be retained long-term and stably.
The surveying and layout plan includes: the basic requirements for surveying and layout; site preparation for surveying; and the verification and adjustment of initial reference points.
Surveying and setting out of the field control network; layout and stakeout of structure locations and trench excavation alignment lines; requirements and methods for deformation monitoring.
Line verification work; preparation of the schedule for surveying and layout operations, determination of instrument requirements, and allocation of survey personnel, among other tasks.
(3) Verification, Calibration, and Selection of Measuring Instruments
All rangefinders, theodolites, and levels shall be calibrated and verified; they may be put into service only after passing inspection.
The instruments and steel tapes used in measurements must comply with the provisions of the State’s Implementing Rules of the Measurement Law; they shall be submitted to the local metrology authority.
It must be inspected by the designated inspection authority and may only be used upon passing inspection.
According to the verification procedures for theodolites and levels, during their verification cycle, the principal axis relationships must also be checked.
The station is calibrated to ensure observational accuracy.

(4) Establishment of the Control Network
Based on the traverse and elevation control points provided by the planning department, establish a traverse control network and an elevation control system within the construction area.
The control network has been established and approved through verification by the supervising engineer and the owner, serving as the basis for construction.
