The council commissioned SGL Group alongside BOON Team Architects and Rawlinsons Quantity Surveyors to do the survey which faced delays due to Covid-19. Chandulal-Mackay would not talk about options.
"All I can say is that as councillors all we want to know is if there are other options. When we make a decision we have to look at more possible options," he said.
He would not say whether other options have been discussed in the recent meetings.
The council has agreed in principle to support a velodrome roofing project, and in 2017 said it would provide $1 million toward it.
Last year it got a final report into roofing the 1995 structure that's wooden track is deteriorating. The report came to council in September and was discussed with the cycling sector and Regional Velodrome Development Trust in October.
A further meeting between councillors and senior officers was held, and then a meeting with the report writers in December. What was said in all those meetings is still confidential.
Regional Velodrome Development Trust (RVDT) chairman Leigh Grant has not talked to council about the project since the October.
He believes the velodrome must be able to host other events in order to avoid cost to ratepayers.
His trust is adamant that it will work with the council to get the best outcome, he said.
The council needs to make decisions about the velodrome before its draft Long Term Plan goes out for consultation in March.
Before that, Chandulal-Mackay said, councillors will need a full range of options and costs to consider.
The next step is for the report to be released and discussed in a public council meeting.
"My hope is that will be sooner rather than later."
At the same meeting the council could decide to adopt one of the options, and the funding for it, into its Long Term Plan.
"It's pretty imperative that the Long Term Plan gives a solid direction on where we are going with the velodrome," he said.
