I am in the final phase of contract writing (three house suppliers are competing against each other). Materials and prices are precisely fixed, so I will go through the last details tonight. However, they all have slightly different approaches to the construction process, how fast they are, and when they can/want to start; I am thinking mainly about foundation work and house erection, and there are both lösvirke and fabriksmonterad suppliers among the three.
All three show construction times around 16-20 weeks.
I have three questions regarding the timeline:
A) WHEN IS THE BEST TIME FOR FOUNDATION WORK?
My father thinks one should start in the spring. When would you prefer to do the foundation work, and do you see extra costs/risks with blasting and casting in January/February? We will also blast for the slab first.
We could do the blasting this fall; would you have chosen to do it now to avoid it in Jan-Feb?
B) WHEN IS THE BEST TIME FOR STRUCTURE ERECTION?
How much more temporary power is needed if you build in midwinter versus spring? Is snow dust during structure erection a worse moisture problem than spring rain? Other issues with one or the other, and is there a difference between lösvirke and factory-assembled?
C) IS MOVING IN BEST IN MAY/JUNE?
One says structure erection at the beginning of February (foundation and blasting before) with a construction time of 20 weeks, meaning moving in at the end of June. For those who have completed building, is it very advantageous to finish before vacation? Would you have preferred a milder spring construction starting March 1 and moving in mid-July?
All responses are helpful!

a construction period of 16 weeks is too short, the slab must be at a maximum of 85% humidity before the waterproofing can be applied in the bathroom, laundry room. 85% is reached 3.5 months after the house has been roofed and the slab has started to dry if you have cast with a concrete type of k30. I would recommend a construction period of 22-24 weeks, the extra weeks can pay off in the end if you look at the long term. Good luck with your house.
We went with Götenehus. Blasting, tree removal, and groundwork began in February, with the slab poured in mid-March. Frame erection took place in mid-April; as soon as the frame was ready, they connected the underfloor heating with some temporary device that looked like a propane tank to remove moisture. Unfortunately, the construction stopped completely for 6 weeks during the summer, which is frustrating and costly. We moved in 2 weeks ago (Oct 2012). The suppliers' "weeks" are counted from the frame erection. So don't forget about building permits, groundwork, and any potential industrial holidays. In total, it took us 1 year and 4 months from purchasing the plot to moving in. A tough period with double costs on construction loans.
