Bid Ambassador O'Driscoll handed in the 990-page document, which sets out the country's plans to run what IRFU chief executive Philip Browne believes would be "a tournament like no other".
Mr Ross said the event would prove very beneficial to the entire economy and the sporting sector in this country.
South Africa is up against Ireland and France for the hosting rights, with the victor to be announced on 15 November.
Ireland, which has never hosted the tournament before, are joined by former hosts South Africa and France in the race to stage the major worldwide event.
Ireland's candidature file was submitted to World Rugby headquarters in Dublin by a delegation led 11 year old "bid kid" Alex Place from Co. "What you spend in one week in a hotel in Europe you can spend over three weeks here".
South Africa did that on Tuesday, and SA Rugby CEO Jurie Roux is confident that he has a winning bid.More news: South Florida Protesters Say Withdrawal From Paris Climate Accords Is A Betrayal

"We can sell 2.9million tickets". Unlike other mega-sporting events, South Africa would profit from hosting the tournament. "No infrastructure spend would be required and the economic impact study we have commissioned from Grant Thornton has a good news story to tell South Africa".
"This will be the biggest World Cup ever with 2.9 million seats".
Minister for Sport Shane Ross has said emergency legislation may be needed to ensure Ireland can continue to bid for the 2023 Rugby World Cup.
"It has already been shown in the North we have a proven track record of hosting major global events including the G8, Giro d'Italia, MTV Music Awards, the World Police and Fire Games, the Clipper round the World Yacht Race and the Irish Open Golf Championship".
After receiving advice from the Attorney General, Minister Ross drafted the Rugby World Cup 2023 Bill (2017) to help support Ireland's bid and it was approved by the cabinet last week.
It took 24 months of planning but Roux believes their bid to host the 2023 Rugby World Cup is more comprehensive than the competition after delivering their final bid documents ahead of their deadline on Wednesday.
