Introduction
Construction technology disclosure plays a crucial role and is ultimately incorporated into the project’s completion documents. It provides essential guidance for on-site engineering operations. We have compiled a list of key points to help you deliver a “perfect score” technical briefing—don’t miss these insights.
1. How to Prepare
Tools and Raw Materials
(1) Construction drawings: including drawing descriptions, disclosure, reviews, and any changes.
(2) The construction plan or organization design related to the specific sub-project for disclosure.
Methodology
(1) Carefully review the general instructions of the construction drawings. Familiarize yourself with the contents and clarify the design intent.
(2) Based on the construction organization design or plan, study relevant construction techniques, safety regulations, and acceptance standards to understand the required methods and standards.
Drafting the Disclosure and Defining the Framework
(1) Construction Preparation: material, machinery, and labor readiness.
(2) Construction Scope: clearly define the specific scope and conditions covered by this disclosure.
(3) Construction Method: describe the construction technology and methods in detail, illustrating each step in the process using arrows (“→”) where appropriate.
(4) Acceptance Criteria: establish standards based on the sub-project’s acceptance requirements and overall project goals.
Precautions
Include both construction precautions, such as common errors and typical issues, and safety precautions relating to the project’s safety requirements.
Measures for Safe and Civilized Construction
These include requirements for maintaining a clean site after work, prohibiting smoking on site, and forbidding work under the influence of alcohol to ensure safety and professionalism.
II. Main Content
01
The chief engineer or technical lead of the construction unit must conduct a technical briefing for the construction team or site manager, covering:
- An overview of the project along with all technical and economic indicators and requirements;
- Main construction methods, critical techniques, and any known implementation challenges;
- Technical details and precautions concerning special engineering locations;
- Plans, implementation strategies, and precautions for new technologies, methods, materials, and structural techniques;
- Construction organization design, network plans, scheduling, resource allocation including machinery and labor;
- Coordination between the general contractor and subcontractors, and resolution of related issues;
- Construction quality standards and safety protocols, emphasizing standardized procedures promoted by the company.
02
The construction team’s technical leader must disclose technical details to the project leader, quality inspector, and safety officer, including:
- Project status, local topography, landforms, engineering geology, and relevant technical and economic indicators;
- Design requirements, methods, and construction challenges specific to modular construction;
- Detailed requirements and procedures based on the construction organization design or plan;
- Construction methods, process standards, and company-specific procedures;
- Key locations, potential issues, and their solutions during implementation;
- Schedule requirements, workflow overlaps, and task assignments for departments and teams;
- Main machinery models, quantities, arrival times, and operation procedures used;
- Operating procedures, technical regulations, and precautions related to new processes, materials, and structures;
- Measures and precautions to ensure construction quality and safety standards.
03
The unit project leader or technical supervisor must provide technical disclosure to operation team leaders and workers, focusing on:
- Specific technical requirements and construction process standards or internal methods for each sub-project;
- Quality standards for the sub-project;
- Preventive measures and precautions for common quality issues;
- Safety briefings, including lessons learned from past accidents and specific safety measures to be enforced.
