US Battleship Construction
Charts and graphs below shows the evolution of US battleship construction with TEXAS as part of that evolution. The 57 completed battleships plus the Maine and Texas (1890s) were of 22 different classes and built in 12 different locations. Even though ships became ever longer and heavier, construction time generally decreased. 
Of the 59 built:16 in four US Navy Yards. 42 in eight commercial yards

  US Navy Yards vs Commercial Yards  
Of the 22 classes of battleships, only 6 involved construction in both USN Yards and commercial yards. The USN yard in blue. 
My comparison is limited to same type of ships and measured by the number of build days. 

The "Congressional Record" entries for the TEXAS-NEW YORK authorization show concern that Navy yards would be more expensive than commercial yards because of Federal labor laws that applied to Navy Yards but not to commercial yards, would add additional cost.
NEW YORK (built in a USN Yard) cost $350,000 more than TEXAS.
