 All four ships were laid down on 16 June 1909, but this was just a ceremonial event as actual work did not begin until September – October. One major complication was that the design for the turrets and their magazines was not completed when construction began so their weights and dimensions had to be estimated. The machinery for these ships was built by either the Baltic Works or the Franco-Russian Works as the New Admiralty Shipyard lacked its own engine shop. Construction was initially very slow because the Duma did not allocate any money for these ships until May 1911. Initial funding was taken from other budget items or the emperor's discretionary fund and the shipyards had to use their own money to keep the work going. They were enormously expensive with their cost estimated at 29.4 million rubles each, including armament. By way of comparison the preceding class of pre-dreadnoughts had only cost 11 million rubles each. Once the Duma provided the funding the pace of work accelerated and the ships were launched later that year, although delays in the delivery of engines and turrets hindered their completion. All of the ships completed abbreviated trials by the end of 1914 and reached the fleet in December 1914 – January 1915.
