They're just saying, saying it with photos on page 568 of the December 8 issue of The Engineer in 1905, that it's a Liner being built for Cunard. They don't say what it's going to be called.

They do refer to it as another great Cunard Liner, and report where it's being built:
The Construction of A Great Liner
Through the courtesy of the builders — Swan, Hunter, and Wigham Richardson, Limited, of Wallsend-on-Tyne — we are enabled this week to give half-a-dozen reproductions of photographs of the express passenger steamship they are building to the order of the Cunard Company, a similar vessel, as is well-known, being under construction in the yard of John Brown and Co., Limited, Clydebank. The pictures illustrate in a striking way a great ocean steamship "in the making," and in the earlier stages. They also give a fair idea of what the facilities are in an up-to-date modern shipyard provided with overhead electric crane equipment for dealing with the erection and conveyance of material, and with the transporting, and holding to their work, of hydraulic and other appliances for drilling and riveting material of the heaviest scantling now worked into merchant ship structures. The covered-in shipbuilding berth on which the great Cunarder is being built at Wallsend is 740ft. long — but can at any time be extended to 900ft. — with a clear inside width of 100ft. and a height of 144ft. All the covered-in berths are equipped, as is seen on some of the engravings, with numerous electric overhead cranes.

Here's the shot that gives you the scale of the thing. They are engineers that did stand in that.
Oh yes, the vessel. It would be launched the following year, 1906, by one Anne Emily Innes-Ker (1854-1923), née Spencer-Churchill. The four-funnelled (it was going to have three, but they had a rethink) floater would be known as Mauretania.
