Above: Titanic under construction.
220 - the height of the gantry built over the two ships (RMS Titanic and her slightly smaller sister, Olympic), in feet - fittingly the largest gantry in the world at that time.
3 - the number of years it took to build the RMS Titanic.
$7,500,000 - the cost of building the Titanic (£1.5 million).
3,000 - the approximate number of men employed in the construction of the Titanic, around 20% of the Harland & Wolff workforce.
8 - the number of construction workers killed during the build - keel laying to launch (there was an unwritten expectation in shipyards at the time of 'one death for every £100,000 spent, so at a build cost of £1.5, the Titanic's toll was less than the 15 deaths that might have been expected).
Above: Building the Titanic at the Harland & Wolff shipyard in Belfast.
3,000,000 - the number of rivets used in the construction of the hull, a mix of iron and steel.
200 - the number of rivets that a 4 man riveting crew could complete per day (assuming dry weather conditions).
15,000 - the number of days work this rate of riveting would have represented for a 4 man crew.
20 - the number of horses needed to transport the main anchor.
401 - the yard number within which the Titanic was built, at the Hartland and Wolff shipyard in Belfast.
14,000 - the number of men employed at the Harland & Wolff shipyard.
