abcd ef CO-Eng/A&C CO-Eng / A&C Manufacturing Buildings Introduction January 2013

abcd ef CO-Eng/A&C Design Principles for Manufacturing Buildings 2 Where feasible group several small building volumes into one bigger building with simple shape, regular building grid and consolidated roofline. Establish clear hygienic zoning. Group rooms with similar indoor requirements where possible. All elements fit for cleaning and maintenance. Ensure safe circulation on site by separating people and traffic flow and providing comprehensive signage. Provide safe and healthy workplaces. This is Nestlé policy and important to achieve environmental labels like LEED (US Green Building Council). Conceptually integrate building structure & envelope with technical services of the building, including building related industrial services elements.

Strive for compact buildings with simple shapes and rooflines; avoiding complex building agglomerations.

Establish clear hygienic zoning based on the process flow sheets. Identify space needs per functions and define their relations. Define indoor conditions like temperature/humidity, floor finishes, drains, wall finishes etc. Hygienic Zoning 4 Example

abcd ef CO-Eng/A&C Building Volumes and Composition 5 Harmonizing Building Volumes, showing tower buildings as separate volumes. The most effective architectural approach to reduce the CO2 footprint due to the grey energy embedded in construction materials is to make buildings compact, with simple shape and with a building shell that is suitable for the local climatic conditions.

Strive for flush facade surfaces without apparent structure. Openings only where absolutely required (workplaces, orientation). Screens (e.g. from stretch metal) can be used to consolidate small building units of different type and technical installations into a homogenous simple building volume. Consider day and night effects and harmonize Building Volumes.

abcd ef CO-Eng/A&C Building Structure 7 Foresee future expansions and changes/increases of equipment for waiting beams or columns. Consider equipment loads and vibration for the structural calculation. Concrete structures can crack and bolts in steel structure can become loose. Conceptually integrate building structure & envelope with technical services of the building, including building related industrial services elements. Optimize for short ducting & piping, preferably without cladding; building and equipment are closely linked. Provide wall and ceiling penetrations for piping and ducting properly sealed.

abcd ef CO-Eng/A&C Choice of Materials and Finishes SIKA MEMBERS AREA It is an information platform which contains approved Sika Solutions according to Nestlé’s requirements for different production areas. 8 Prefer easy to clean and easy to maintain materials for platforms, stairs, ladders such as stainless steel. Good quality water-based paint is preferred over solvent-based because solvents may release Volatile Organic Compounds (`VOC`s`) with toxic impact on the environment and enhancement the buildup of moulds. Electrically conductive floor in explosive areas (dust explosion) is recommended. Resin based coatings such epoxy. Advantages: smooth, easy to clean finish, resistant to chemicals with the right additives, fast to install. Disadvantages: requires skilled people to install it, no slopes possible, more expensive per sq. meter Flooring solutions should balance between easy to clean and non slip finish for safe working conditions.

abcd ef CO-Eng/A&C Signage Verify that the colors are not in conflict with local laws and standards. 9 Ensure safe circulation on site by separating people and traffic flow and providing comprehensive signage. Clearly mark emergency exits, use also coloring and graphics to direct people and traffic flow.

abcd ef CO-Eng/A&C Security, Safety and Health 10 Wide doors allow to remove equipment for maintenance to the workshop easier. Prefer fixed platforms to access manholes in equipment instead building a scaffolding for every inspection or maintenance procedure. Ensure safe access to roofs. Install safe inspection and maintenance access when necessary and walkways protected with barriers. Control Room must have good visibility to the process area, with proper ergonomics and lighting design for good working environment. Producing highly sensitive Nestlé products requires full attention of the operators and to the workplace environment.
