Update
The Sharks board will tonight consider an expected recommendation to close the leagues club for nearly two years during redevelopment of the site.
The board will also look at options for moving games from PointsBet Stadium for two seasons.
Sharks board members and management met with representatives of developer Capital Bluestone on Friday and over the weekend to discuss options.
The board meeting on Tuesday night will make final decisions, which will be conveyed to members, sponsors and other stakeholders on Wednesday and Thursday.
Group CEO Richard Munro said he was likely to recommend to the board it would be better to move out of the leagues club temporarily "and get out of the way of the builder".
"Otherwise, the construction will drag on in and around the club and it will be very difficult for anyone to get in," he said.
Mr Munro said if the board adopted that option, an arrangement would be sought for Sharks members to relocate to another club for the duration of the project.
"We would be delighted to talk to anyone who is interested in working with us if we go down that route," he said.
"Our absolute priority is making sure our members are happy, our football team is in a winning position and that our sponsors are engaged with us in working through this.
"There's a fair bit of time before this will happen so we can make sure all needs are covered."
Mr Munro said construction was scheduled to start in mid-January 2020 and be completed in November 2021.
"It's put us in a position where we have to decide whether to keep the leagues club operating or get out of the way of the builder," he said.
"The biggest restriction we are going to find is the lack of car parking because the car park is going for the construction.
"Part of the club will also be demolished and there will be construction all around the club, including the Peter Burns Stand."
"The club will essentially be shrouded [by scaffolding and shade cloth] on three sides."
Mr Munro said the project also involved major works on Captain Cook Drive outside the club.
"It has been a very lengthy process of decision making around options for the club for the intensive construction we are about to go through," he said.
"The exciting part is it's all happening. It has been speculated upon for years.
"It's a real game changer for the club."
Mr Munro said a major feature of the redeveloped club would be a very large food and beverage deck overlooking Woolooware Bay.
"It will be on of the largest, if not the largest, in Sydney," he said.

The Sharks Leagues Club may be closed for 18 months to allow the Woolooware Bay Town Centre development to be accelerated.
Closing the leagues club would be combined with moving Sharks games to other venues for two seasons, with Netstrata Jubilee Stadium, home of arch rivals St George Illawarra, the preferred option.
Sharks board members and management met with representatives of developer Capital Bluestone on Friday to discuss options and the talks will continue over the weekend.
A decision is expected to be known by Monday.
Stage four of the Woolooware Bay Town Centre development, on the leagues club car park site, is scheduled to start by the end of this year.
It will include new apartment blocks, Bay Central shopping centre, a hotel and a redeveloped leagues club.
"The leagues club will effectively be gutted and rebuilt," a Sharks spokesman said.
"They question to be decided is whether to do it floor by floor or shut it down and accelerate the work.
"If it is closed, it will be for about 18 months."
The spokesman said special arrangements for members would be put in place during that period.
The spokesman said taking Sharks games to other venues needed the approval of the NRL.
"Taking a significant number of games to Kogarah is Option A," he said.
