You have started a Tier 3 Ocellus starport and are 7% complete with 21 days 2 hours remaining
It looks like you have cleared commodities with smaller amounts. If you have a large ship it may speed up slightly now and everything you need is reasonably near. Quantities might run dry and require sourcing elsewhere but plenty of choice nearby
Varley Plant, Atora : CMM Composite, Ceramic Composite, Liquid Oxygen
Grijalva Sanctuary, Pegasi Sector JI-R b5-0 : Titanium, Aluminium, Steel
If a few of us can help out and you speed up somewhat it could be achievable. The alternative is to cancel construction, and in a day or two when it becomes selectable again you could consider a Tier
3 edit: 2 Coriolis (about 1/3 the effort), or a Tier 1 outpost (about 1/9 the effort). See this link for suggestions around refinery with Tier 1 civilian outpost
I've been gradually building up facilities in my system (Synuefe QP-F c27-6) including a surface science base, a coriolis station, an asteroid station and several outposts. Most economies seem to be present but not a Refinery one. What's the best way of introducing that? P.S. My asteroid base...

Edited to correct Coriolis tier. Also, consider the orbital station is relatively unimportant in a refinery (as I understand). Your planetary body has no construction slots so it would be a shame to see you burn out getting an orbital constructed that cannot have a refinery or refinery economy
