AXTF Metalworks Pte Ltd manufactures metal components for a variety of industries. Recently, they have expanded their business to include trading and sale of metal products. With the new company, they increased their headcount from 50 to 120 employees. Of these employees, 50 work in production, while 70 are located in the warehouse and office building.  Being in the essential industry, all the employees are working on-site and not from home.

The site they are located in comprises a production building, warehouse, and a two-story office as shown in the layout below.

The office building is about 30 years old. The two floors are each served by a separate air handling unit. Due to energy conservation, only a very small percentage of the windows can be opened for ventilation.

To cater to the increase in headcount, the company renovated Level 2 of the office building, which was originally used as a store. Each office floor is about 300 sq. m and consists of open-plan workstations, a printing room, a pantry, managers’ rooms, and meeting rooms.
