The Method Statement is a document which defines rational organization of construction work in accordance with the process rules, occupational health and environmental requirements and work quality requirements at the specific construction site. This document is prepared to select the efficient construction and installation technology to improve the work quality. The Method Statement is the main document in the system of organizational and technological preparation of construction work which covers the following functions:
1. Regulates the organization of work performance at the facility in accordance with the process rules, occupational health and environmental requirements and work quality requirements;
2. Defines the sequence of equipment installation and arrangement of the construction site;
3. Enables construction process modeling, forecast of possible risks and definition of optimum construction period.
Development of Methods Statement
The method statement is prepared based on the construction arrangements design and defines in more details the construction arrangements design concepts for individual facilities at the construction site. Therefore, the method statement cannot contradict the construction arrangements. The construction arrangements design document covers all the facilities at the construction sites in general and the Method Statement document is focused on each facility at the construction site and each work type individually.
Content of Method Statement
The main parts of the Method Statement document are the Work Schedule and Construction Master Plan which form the basis for preparation of lists and schedules of various resources consumption. In certain cases, the method statement can be prepared for the entire scope and for a part of the work scope. The full scope Method Statement includes:
1. Work schedule for the site, i.e., model of construction process which defines the rational sequence, priorities and periods of work performance at the site;
2. Construction master plan, i.e., the document which defines the boundaries of the construction site; layout of permanent, unfinished and temporary buildings and facilities, operating, new and temporary underground, above-ground and overhead networks and utilities, permanent and temporary roads; installation points of construction and load-lifting machines with indication of their movement tracks; locations of power and water supply sources and elements at the construction site; locations of material and structure storage, pre-assembly areas, etc.;
3. Schedules (delivery of civil structures, items, materials, and equipment to the construction site; main construction machinery requirements; personnel movements at the site);
4. Process charts for performance of individual work types;
5. Layout of geodetic markers;
6. Explanatory notes. If necessary, the Method Statement may include other sections covering the construction and installation activities upon the Customer’s request. For this purpose, corresponding requirements are included into the technical specifications for design work which forms an integral part of the contract on the Method Statement development.
