I got two quotes from different draftmen, which one better

I got two quotes from different draftmen for my extension (60 - 70 M2 for a family room and one extra bedroom). one draftsman charges 50% more than the other.

The first quote includes:
Single storey house extension
Purchase of existing survey plan
All drawings necessary for certification
Any small design changes going forward
(not included: 3D Images)

The second quote includes:
Site plan
Existing floor plans with demolition notes
Proposed floor plans
Elevations
3D Views
Sectional Views
Slab setout plans
Blank electrical plans with key
construction notes and tiedown specifications.

My question is:
Does "All drawings necessary for certification" in the first quote covers all the items (except 3 D view) listed in the second quote?

 

I have no idea. The extension is in the backyard so I don't need survey plan. But he quote the cost for the purchase of the survey plan is $20. So I didn't bother to ask the detail.

 

that $20 would probably be just to order the deposited plan. that isnt for a surveyor.

 

No, it was very clear the $20 was for the purchase of existing survey plan. The deposit for the drafting is $400, and the rest cost will be paid once it's done.

 

I’d work out which one can actually draw a plan and then pay the money he she asks. Cheap poor plans = higher build costs.

 

So notes from my experience

1. did they give you what drawings are going to be in 1:100 or 1:50 scale (1:100 is fine for general areas Living rooms, bedrooms ect, But 1:50 is great in Kitchens, bathrooms where you need the extra detail for cabinetry .

2. Look at previous work or clients, my Architect didn't have any and I know why now

3. What's a small design change, flipping a door opening or moving a door? We had 6 revisions of drawing and only paid for 1 as most of the time it was items he missed from my marked up plans, even though I used a highlighter to cloud the area and wrote detailed notes.

4. Will they come to site once or twice if needed Think Check measures issues or create a solution to a unknown problem once Demo starts, such as hidden service.

5. Can they review Kitchen, laundry and bathroom joinery drawings to confirm they work in the space they have drawn and there is no services conflict or issues. This is handy when looking to add power points, drains, A/C vents, lights, water pipes, plumbing and electrical. 2nd set of eyes

6. Will you get a electronic copy of the drawings and a hard copy for future reference.

Your second quote looks more detailed, which will lead to easier builder quotes and less grey areas during the build, but you could ask quote one for clarification to make sure your comparing apples with apples

 

Good idea. Thanks

The first quote doesn't include any details. Potentially it can be a problem.

Thanks Something_Wrong
