1828 Company established as an engineering business. 
1838 John Scott Russell was appointed general manager.
1840s The company began making large paddlers for various companies along with smaller Clyde paddlers. After winning an order of four ships for the Royal Mail Steam Packet, Caird and Co moved into shipbuilding in 1840, and went on to become one of the most well known shipbuilding companies ever.

1852 Forty-five ton crane at Greenock Harbour.

1867 Vacated the Mid-Cartsdyke yard as the company had already taken over the Westburn East yard.
1871 Took over the Westburn West yard. As of 1870 P. & O. was the main customer for the yard, for whom it built 85 ships. The yard enjoyed an exclusive relationship with P. & O., but also built liners for many other companies too. In between all of this, the yard also managed to build an iron sailing ship and a small number of steam yachts in the 1880s.
1888 James Caird died. He had already brought his four sons Patrick, William, Arthur and Robert into the company. One of the first things they did was to turn the Company into a limited liability one. The yard continued making liners and passenger ships throughout the 1880s. The company was registered on 19 December, to take over the business of the firm of the same name, engineers and shipbuilders. 
1889 See 1889 Shipbuilding Statistics for detail of the tonnage produced.
1890-1914 The yard built over 32 liners for P. & O.'s long haul routes which was its main output.

1915 Robert Caird died in December.
1915 The Company was taken over by Harland and Wolff. Arthur and Patrick Caird remained as directors, and the Caird name remained in use until 1922.
1919 Many changes occurred as Harland and Wolff extended their interests into surrounding yards and expanded the capacity of the yard. At this point in time the yard employed over 2000 workers.
1920s The slump in orders meant that the planned rate of expansion slowed, and was eventually suspended. However, the yard was still able to build larger vessels, and did this throughout the 1920s.

1926 No ships were launched from the yard in 1926.
1927 Only four ships launched.
