Abstract

The ACME Semiconductor Foundry – Fab Expansion is a new four story addition to an existing four story foundry facility. The Fab Expansion is approximately 154,500 square feet in footprint area that is connected to an existing four-story Fab Building. This report has been prepared to identify the building’s fire protection and life safety features that must be provided in accordance with the applicable codes and standards. The ACME Semiconductor Fab Expansion will contain multiple separated uses and will be required to be constructed with Type I-B construction. Building Construction Documents are provided in Appendix A showing compliance with the requirements found herein. There are multiple occupancy classifications within the building. The predominant use of the building is semiconductor fabrication (H-5), with some storage of hazardous materials (H-2, H-3, and H-4). The structural fire protection requirements are presented. The structure, being Type I-B, would normally require 1-hour fire resistance rated roof supports. Other prescriptive structural requirements are shown to be compliant. A performance based analysis is presented showing that the roof support does not reach critical temperatures for duration of one hour when exposed to a worst case credible fire scenario. The sprinkler system design requirements for the ACME Semiconductor Fab Expansion are presented showing various sprinkler system design densities. The most demanding case occurs in the Solvent Storage Room with 0.30 gallons per minute per square foot over a design area of 3,000 square feet. A summary of the inspection, testing, and maintenance requirements related to the fire sprinkler systems has been provided. This report presents the relevant fire detection, alarm and communication system design requirements for the ACME Semiconductor Fab Expansion. An excerpt of fire alarm design drawings has been provided in Appendix G showing the general code requirements, typical notification device layout and spacing, and a unique detection situation utilizing radiant-energy sensing detectors. Detection response analysis has been performed using DETACT, FDS, and manufacturer’s data for the unique flame detector situation. A brief summary of the inspection, testing, and maintenance requirements related to the fire alarm systems has been provided. This report presents the relevant egress requirements for the ACME Semiconductor Fab Expansion. Life Safety Plans are provided in Appendix K showing areas of non-compliance with the prescriptive requirements of the LSC. Use of the IBC would yield compliance acceptable to many authorities having jurisdiction. The egress calculations shown and simulated provide the basis for a performance based design of the egress systems in this building. This report can be used to establish the RSET value to be compared to an ASET value determined through the use of a CFD fire model. Recommendations include conducting a fire study to evaluate the egress systems in accordance with the LSC for high hazard industrial occupancies. The performance based analysis provides the thermal exposure and demand to capacity ratios for the exposed structural steel. A structural engineer can utilize the thermal exposure criteria to determine whether a critical value is reached in the exposed structural steel.
