INTRODUCTION

The Empire State Building will be a symbol of confidence in the United States of America, in view of the fact that, upon completion, it will be the tallest skyscraper in the world. The building will be constructed with the intent of being considered the skyline symbol of New York City.

The Empire State Building was designed by the architectural firm, Sheve, Lamb & Harmon Associates by Starrett Brothers & Eken, Inc. It is scheduled to be completed in 13 months finishing in May of 1931, with a total projected cost of $24,718,000 for the building, and the property cost $16,230,990, which is about two acres. This is half the amount anticipated due to the ongoing economic depression. Excavation is scheduled to begin on January 22, 1930, and construction will start two months later on March 17, 1930. The building framework is estimated to be completed at a rate of 4 ½ stories per week.

RISK #1 DISCUSSION: Production of Steel Mortars

By using a Decision Tree Diagram, I have ranked the risk according to manageability and probability of success. The probability that the materials will be imported on time from France and Italy and meet specification has a 100% successful outcome. The probability of any delays due to poor quality, late shipment and safety of materials has a 33% chance for each occurrence. Some of the pieces of marble will be created at an off-site facility in the United States of America and must be transported to the construction site. The pieces designed in the U.S. have a 33% risk of not meeting specification, if they are made too small or incorrectly. No time has been built into the schedule to re-create any pieces.
