  1. Signed with first choice builder (glowing references, reasonably good quality of viewed builds & good to get on with), on terms not far off what we aimed for. Many thanks to all on the forum who helped us edge forward to this stage. Perhaps the experience so far can help others who are at an even earlier stage with even less experience than us. Financial terms in essence are 50:50 pain or gain share with builder, after protecting their normal profit & overheads + allowing them builder contingency. The lower the hard costs (paid to suppliers) the more the builder makes (and we save). Price increases during the build to be borne 50:50. Variations to be priced benchmarked against SPONS, and if too pricey (or even if not) then we have the right to seek alternative quotes (potentially needing to pay 10% of quote as builder's profit/attendance). If supplier credit unavailable for some items then they will request payment when materials arrive on site and are vested in us, but we retain the right to grant that request or not. We started off telling them that we were interested in a target price without too much "just in case" pricing, with fair profit/overheads that preferably did not depend on marking up costs. Instead, they would get a share in cost savings. Then we sent them (and some other good builders) detailed drawings & specifications plus Estimators Online, something like a bill of quantities & programme of works. They then got their own Estimators Online quote, marked it up a bit, eased the programme of works a bit, and submitted it to us in that format. Hopefully these details will make it easier to value work completed. No deposit, but weekly payment for work completed. At least two thirds of the final completed build is awarded. Relief at getting to this stage, but the work of trying to find better quotes goes on. Thanks again to all for the excellent advice and sharing of experiences.
  2. On the verge of signing contract with a builder who seems suitable in nearly every way. For site facilities hire, what are the usual payment terms? Deposit % plus weekly payments? Lump sum up front? Arrears? Trying to work out what advances (if any) the builder is likely to be paying out to their suppliers. Will allow informed decisions about payment schedules.
  3. From when is the credit period counted for goods? From delivery to the customer? Or from some other date? And how long is the credit period for a seasoned reputable builder?
  4. Trench for services likely to run very near site boundary/ security fencing. At very top of pic. What kind of site fencing, if any, would allow that?
  5. Seems a good solution. "Advance payment" bond seems to be another good solution, the person receiving the deposit would be required to furnish such a bond.
  6. Builder we're likely to go with is member of the Fed of Master Bldrs Includes all risks insurance, public liability, employer's liability. Includes client as insured under "indemnity to principals" clause. Only risks remaining with us at the site and for the build are a) something caused by our negligence b) something caused by the work, but not as a result of negligence by anyone c) default by the builder for any reason Writing that down helped clarify what we need to do insurance-wise
  7. Traditional build new house. 2 storeys, 200 sqm No piling required.
  8. What is the industry norm for deposits/advances to builders? Builder accepting all terms suggested by us. We discussed nearly all that was relevant. However, not discussed deposit/advances but he mentioned deposit in passing without mentioning any sums. Question: given the favourable circumstances, what deposit/advance could reasonably be acceptable to a client? Industry norm would be a good reference point for decisions.
  9. Building better than the drawings is the option being considered (scottish style waterproofing for England) Interested in hearing about what people might choose and why a) OSB3 / breathable watertight membrane / counterbattens / battens / slate on hooks (or nails) b) tongue and groove sarking board + membrane (no counterbattens/battens) / slate on hooks (or nails) c) 150mm wide sarking boards + rest as in b) Relative cost of a) vs c) per sqm is what I'm trying to work out
  10. Thanks, that is the opinion I sought Noted all the other points, thanks Good point about disincentive for overruns, the incentive payment at the end needs to be paid whether or not there are overruns, but be reduced by the amount of the overruns. It is for the builder to say what suits them. In essence, they are being offered an opportunity to make more money than their quote by exercising reasonable cost control. They can always say no to more money.
  11. Looked at the approved docs for Structure, they do not prescribe. Is there another official BR doc that contains required design details? Would be good to see it. Considerable flexibility to optimise the design for good cost/function ratio. Not tied to anything other than what the BCO might say. These would not prevent a BCO from requiring tweaks to details, since the BCO is the final judge for completion OR final certificate Quote already in. Sharing in cost savings would merely incentivise careful cost control. Together with an incentive payable at the end if the build is brought in under the quote price. Disincentive for cost overruns will be co-pay of overruns (eg 25% carried by builder). Interested in all points of view on incentives too, although the topic is whether or not to nail/hook directly into sarking board(s) through the breathable membrane. Cost/function is the criterion Also very interested in hearing about people's experience with different kinds of slate. Weathering/non weathering etc.
  12. Underlay boards: either a) OSB3 or b) tongue and groove sarking board OR c) traditional Scottish timber sarking boards (150mm wide) All would have breathable watertight membrane over, then slate. Only b) or c) might work without battens & counter-battens. Which would you choose out of a) b) c) and why? Cost is a consideratioin. Would you use weathering slate or non-fading slate? Slates will not be visible from ground, except from some distance. - - - - - PS Cold roof, ventilated attic space. Central attic space will allow some storage and perhaps a bookshelf/chair for the summer (roof light available). Private BCO is preferred route of architect who did the BR drawings and will do the CML certificate. Presumably approved drawings will not prevent BCO from requiring tweaks to details, and we will have to agree a schedule of rates + a formula for variations/unforeseen work Intention is to incentivise builder to control costs, by sharing half of any savings as a result of design/specification tweaks in the course of the work. Hence initial notice and final certificate preferred.
  13. Low pitch hence sarking board advised by architect in order to allow natural slate Question is whether to go for OSB3 sheets (+counterbattens & battens) or traditional sarking boards with 2-3 mm gaps between. PS Builder once appointed will deal with BCO
  14. Natural slate required. Can try to have planner approve natural for the 22.5 degrees and interlocking for the 19. Does Building Control in England allow slate hooks to be driven directly into sarking boards (covered by breathable membrane)? Or is it necessary to have counterbattens & battens?
