Construction Process: Time and Technology Structures
Operation Preparation
Operation preparation involves updating subjects and times for production preparation and activities directly needed for performance and construction. This includes operative plans, orders, and invoices, all updated based on work progress. The site manager carries out operation preparation on-site. Key outcomes include:
- Operative plans (weekly, monthly, 3-month)
- Test protocols and quality records
- Invoices for works (typically monthly)
- Updated time schedules
- Information on construction deadline compliance
- Operative records for daily work
Technology and Time Structures
Technology Structure
A building process’s technology structure exists in time and space and must be described accordingly. It comprises:
- Division of the general process into property-related processes, further divided into processes relating to the building volume, stage processes, and sub-processes.
- Sequence of these processes.
- Technological links between processes.
- Labor force and its structure.
- Work tools and their structure.
- Work items and their structure.
Most important parameters:
- Number of properties, building volumes, and technology stages.
- Number of building sub-processes.
- Scope of production.
- Labor consumption and productivity.
- Labor force number and composition.
- Number of machines and equipment.
The number of properties is determined from layout drawings and project documentation. Building volumes and technology stages are typically determined through technological analysis of the property process, depending on the spatial structure. The number of building sub-processes is determined using a technology aggregation standard for all procedures listed in the property analysis or production calculation.
Time Structure
The time structure of a building process arises from time links with the spatial and technological analysis. It cannot be analyzed independently. It comprises:
- Time sequence and schedule of all property, stage, and building sub-processes.
- Time evaluation of links between processes.
- Time-based resource needs (finances, labor, materials, machines).
Most important parameters:
- Duration of a building sub-process.
- Time and duration of stage process deployment.
- Time and duration of property and building volume process deployment.
- Time values of relations between processes.
- Starting and ending dates for building processes.
Time structure parameters are expressed in time units (days, weeks, months). Starting and ending dates can be expressed relatively (time units from construction start) or absolutely (calendar day).
