Construction site management is an intellectual task that demands the wisdom and experience of managers. How can one effectively manage a construction site and ensure the efficient operation of the project department? The answer lies in proper resource allocation, strategic layout, and informatization.
1. Resource Allocation
Staffing
(1) Personnel should be assigned based on the specific critical points of the construction project. Clear requirements must be set for the types and quantities of labor needed. The number and arrangement of workers should be adjusted flexibly according to the project schedule.
(2) Technical management staff should be allocated according to the quantity and types of labor. An organizational structure comprising leadership, functional, and operational levels should be established to support smooth operations during peak construction periods. Technical staff must meet the required skills, professional categories, and numbers, with assignments made according to construction needs.
(3) Professional and technical personnel must hold valid certifications and receive training on new technologies, materials, and processes.
Material Allocation
(1) Purchasing personnel should understand market supply, price fluctuations, quality, and supply capacity for bulk materials to proactively adjust purchasing plans.
(2) Annual, quarterly, monthly, and weekly demand plans for construction materials should be prepared in advance based on overall and subproject schedules and submitted for approval.
(3) Supply contracts must be signed with material suppliers, clearly specifying quality standards, quantity requirements, and delivery times.
(4) To prevent unqualified materials from entering the site, the project department should appoint dedicated personnel to supervise bulk materials storage areas. All incoming materials must be inspected for complete certification and verified by laboratory testing before acceptance.
Mechanical Equipment Allocation
(1) Mechanical equipment should be selected considering geological, climatic, and hydrological conditions, as well as principles of efficiency, low consumption, environmental protection, and safety. Equipment power and capacity must meet construction progress and quality requirements.
(2) Equipment allocation must be reviewed based on peak construction intensity and equipment capabilities, factoring in attendance and availability. Two-shift operations may be implemented during peak periods for large subprojects to avoid idle equipment and unnecessary costs.
(3) Repair teams should be assigned based on equipment type and quantity. Maintenance responsibilities should be clear, ensuring high equipment reliability.
(4) Difficult-to-procure or long-lead-time equipment parts should be stocked in advance to avoid delays during maintenance or replacement.
Fund Allocation
(1) Project funds should be managed exclusively for designated purposes, with centralized administration and unified use. Policies to increase revenue and reduce expenses should be enacted to enhance efficiency.
(2) The project manager must clearly lead and oversee project funding management.
(3) Cost management personnel are responsible for preparing monthly income and expenditure plans and managing payment procedures.
(4) The budget officer must submit project progress payment applications on time and handle pre-settlement, claims, changes, and approvals.
2. Site Layout
1. On-Site Layout Principles and Standardized Management
Layout Principles:
(1) Separate employee living areas from construction and production zones to facilitate management.
(2) Use on-site pouring of plain concrete to harden surfaces and establish an effective sewage system.
(3) Arrange the site in stages corresponding to foundation, main structure, and decoration phases.
(4) Protect the surrounding environment with adequate lighting, greening, and safeguards.
(5) Keep site layout compact, making full use of existing buildings where possible.
(6) Ensure smooth transportation by maintaining clear and accessible on-site roads.
Standardized Management:
(1) The project manager is responsible for standardization management, with daily implementation by the standardization leader and property manager.
(2) Implement floor plan management after approval, dividing the site into designated zones with clearly identified material storage areas.
(3) The living area should have rotating duty schedules, regular cleaning, and weekly inspections and evaluations.
(4) Construction areas must be cleaned by those working there and tidied as needed.
(5) Enforce construction gate protocols, including lighting signage, security monitors, 24-hour staffing, and staff identification.
2. Construction Site Roads
(1) Roads must be unobstructed and allow circulation to meet transportation and fire safety requirements.
(2) Main roads should be flat, solid, and equipped with drainage systems.
(3) Roads should form circular routes around unit projects, with turning radii exceeding the requirements for the largest vehicles.
(4) Roads should be crowned with drainage on both sides. The main road width should be at least 3.5 meters, and heavy-duty truck turning radii should be no less than 15 meters. If constrained, compensatory measures should be taken.
(5) Whenever possible, permanent roads should be used or constructed first, with paving completed before the main project is finished.
3. Fence (Wall) Arrangement
(1) Fences must be continuous around the site perimeter, designed considering local geology, climate, and materials to ensure stability and safety.
(2) Fence materials should be sturdy, stable, orderly, and aesthetically pleasing; preferably masonry or metal plates. Avoid using colored cloth strips, bamboo fencing, or safety nets.
(3) Fences should generally be taller than 1.8 meters; within urban areas, a minimum of 2.1 meters is required, complying with local regulations.
(4) Do not store loose materials such as soil, sand, gravel, scaffolding, or formwork inside the enclosure.
(5) After rain, strong winds, or during spring thaw, inspect fence stability and promptly address any issues.
4. Layout of Vertical Lifting and Transportation Equipment
Vertical Transportation Equipment:
The winch should be positioned at an appropriate distance from derricks or gantry cranes, allowing operators a clear view of the lifting process. The number of derricks and gantry frames depends on construction progress, component volume, and shift efficiency. Their service range is typically 50–60 meters. Derricks should be erected outside external scaffolding, maintaining a distance of about 5–6 meters.
Self-Propelled Pole Crane Layout:
When positioning self-propelled pole cranes, consider lifting height, component weight, turning radius, lifting method, and building shape. For decoration projects, the minimum lifting arm length of fixed vertical equipment is typically referenced to avoid collisions.
Tower Crane Layout:
(1) Tower cranes must have amplitude and lifting capacity that meet main structure construction needs (including foundation stages), with adequate safety margins.
(2) Provide circular traffic routes for trucks and flatbed trailers to facilitate installation and component transportation.
(3) Locate tower cranes near the site’s power substation.
(4) Leave sufficient space post-project for crane dismantling and component removal.
(5) When installing two tower cranes simultaneously, carefully plan their working zones and coordinate operations to prevent interference.
3. Information Management
1. Material Management Plan
The material management plan consists of two parts: the material demand plan and the material procurement plan. The demand plan serves as the foundation, while the procurement plan drives the overall material management strategy.
(1) Effective planning allows company departments to quickly provide feedback on material needs to the material department, with online verification. This reduces tedious communication and significantly shortens material management time compared to traditional methods.
(2) The procurement plan enables timely tracking and acquisition of materials needed to replenish inventory, further advancing material management.
2. Material Procurement
Traditional material procurement involves complex management tasks such as real-time order supervision, material warehousing, and handling returns. Information systems for prefabricated assembly streamline these processes by providing real-time transparency and supervision, improving procurement efficiency. These systems also strengthen coordination between material management and finance departments, boosting enterprise operational efficiency.
3. Inventory Management
Managing inventory quantities and associated funds is a key task closely tied to finance. Information systems enable real-time tracking of material inflow and outflow, standardizing inventory management and integrating fund management to enhance efficiency.
4. Material Supply Management
Information systems standardize material supply management for prefabricated housing by providing real-time monitoring of supply processes, ensuring correct progress at each stage. These systems require verification before any step proceeds, preventing unauthorized or opaque operations.
5. Material Statistics
Information systems require establishing a comprehensive database with detailed records of material names, prices, purchase dates, and more, ensuring data authenticity. Accurate statistics significantly impact company decision-making. The system enables data sharing, reduces repetitive labor, and improves statistical efficiency.
