As we celebrate Haag’s 95th anniversary in 2019, we are looking back at some of the noteworthy projects Haag Engineers and Consultants have been involved with over the last 95 years. This month, in our special double feature, we take a look at collapse of movie set Titanic, and Assessing Hail Damage, Part 2- Hail Inspection Protocol.

Assessing Hail Damage, Part 2: Hail Inspection Protocol
This is the second of a two-part series on hail damage. Part 1 focused on wording choices used in reports to describe hail effects. Part two focuses on proper hail inspection protocol, damage criteria, published research, and terms used in the assessment of hail-caused damage, specifically asphalt shingles. We have already received questions from Part 1 that are addressed in Part 2. If you have not read Part 1 yet, please read that first.
From time to time, we at Haag feel the need to clarify a few important points about hail damage, research papers pertaining to hail published by Haag and Haag’s criteria for damage. It is the latter that seems to have been misinterpreted by many in recent years with respect to asphalt shingle roofing. The last time we published a clarification with respect to hail damage to asphalt shingles was in 2006.

Collapse on the set of TITANIC
In February 1997, Haag Engineers were called to the movie set of the feature film Titanic. Ironically, the 90% scale movie set “sank” near the end of filming.
The overall model was a steel frame mostly on dry land that was clad with metal panels to look like a ship. To simulate sinking, the bow was progressively tilted into a pool of water by lifting the entire frame and cutting the columns shorter. For the final scenes, the bow section was a separate set, supported by a series of hydraulically-actuated cables and buoyant foam blocks to make the set appear to float while it was being actuated with the cables. (The flotation blocks could not support the weight.) Unfortunately, a series of modifications needed to improve realism resulted in support failures that let the set sink, interrupted filming, left expensive actors and crews idle, and impacted actor confidence in the structure.
