plasterboard on dabs

Internal face of same blocks Will ask for perpends to be buttered better. Want to dig heels in on what makes a difference, but not the rest. In general good service

Insulation? Zero carbon? Fire resistance? Other? Can raise relevant points in conversations.

Yes. Will it let in driving rain? Blown-in bonded EPS beads will be in cavity.

Is there an easy way to remedy work already done?

Inner leaf of external cavity wall. Mortar mix 5:1, blocks are 7N aircrete. Doesn't look too good but that's a layperson view. Specified: LABC warranty standards. If not passable, what is the way to remedy work already done? Just pointing enough? And how DO brickies get mortar in perpends?

2 storey dwelling with possible upward extension later. Blown EPS beads cavity wall insulation. Is it advisable to install cavity barriers (fire protection) in the walls during the 2 storey build? If so, what material and at what height?

How then to tie the top plate to the ceiling joist or ceiling nogging? Just enough to fix it but not enough for it to receive the load

Sole plate for stud walls on concrete slab or above celotex(100mm) & screed (65mm)?

100mm concrete slab. Just one sole plate on top of another? Or double width of sole plate? Does hanging possibly loaded cabinets on the stud wall affect the requirements under the stud wall?

Mesh reinforcement put into concrete slab wherever stud walls were anticipated. However, one spine wall (structural) was built a bit in the wrong place. To compensate for the resulting change in floor plan, a stud wall can be built but where the slab is not reinforced. Foundation: Hardcore, slab. Question: Is there an easy way to place some reinforcement under a timber stud wall? There will be some cabinets hung on it. Is it necessary to place reinforcement under partition walls?

One EV charger supplier provided this Figure. Instructions say "Ensure that incoming cables are connected to the appropriate terminal as follows: Earth: Green/Yellow Neutral: Blue Live 1: Brown Live 2: Black (three-phase units only) Live 3: Grey (three-phase units only)" Over the phone the advice was that 32A was required. An example installation guide here: https://s3-eu-west-1.amazonaws.com/podpoint-website/PP-D-130012-15-Solo-Smart-Charger-Install-Guide-1.pdf Question: Is it useful to ask the DNO to connect power to all 3 cutouts, even though all 3 supply cables are on the same phase? EV charging is the intention.

Pipe spacing drawn at (or very near) scale. Obvious problems? Good idea to take pipes around larder rather than through it. Currently no pipes under major furniture in living room. Bad idea?

Looked at CAD designs from suppliers, tweaked inputs, arrived at this. Any problems obvious? Circuit temperatures Circuit layouts Circuits & heat losses Peak capacity Room surface temperature Zones

Ouch. What are the worst things about dot and dab?

BGS info actually cost £84, just checked. Included 24 maps in four thematic sections: o Very significant constraints. Maps highlight areas where infiltration may result in adverse impacts due to factors including: ground instability (soluble rocks, non-coal shallow mining and landslide hazards); persistent shallow groundwater, or the presence of made ground, which may represent a ground stability or contamination hazard. o Drainage potential. Maps indicate the drainage potential of the ground, by considering subsurface permeability, depth to groundwater and the presence of floodplain deposits. o Ground stability. Maps indicate the presence of hazards that have the potential to cause ground instability resulting in damage to some buildings and structures, if water is infiltrated to the ground. o Groundwater protection. Maps provide key indicators to help determine whether the groundwater may be susceptible to deterioration in quality as a result of infiltration.

We faced a similar requirement. British Geological Survey provided a report centred on the site location. Sufficed. Cost about £20 iirc

Builder's subbie plumber mentioned Hep2O 15mm And a bronze pump "secondary return" for quick hot water at kitchen sink, basins Until then I had assumed it would be PEX pipes Question: Is there much in it between Hep2O & PEX pipes? Initial cost is a consideration

As a layperson with no knowledge, it looks as if 3 power supply cables are going into the innards. They are 3 different phases. Is it possible physically to replace those supply cables with others that are identical in all respects, except for being on the same phase?

Does it make sense to have 3 "same phase" supplies to the "3 phase" cutout already installed by DNO? That would enable connection without extra costs.

plus there is this: https://go.ads-tec.de/en/hpc/dispenser#intro Claims ultra-fast charging without needing to upgrade electricity supply, afai can tell

Alternately, if a dual phase 46kVA supply is connected to the cutout as contracted, will a single phase (presumably 23kVA) suffice for fast charging (22kW)?

Found these. But what do they mean? If the DNO connects 3 cables to the cutout, all 3 cables being the same phase, can that enable fast 22kVA charging of electric vehicles?

Nobody knows less about this than I do. But it sounds very promising. Might it be that the DNO can simply connect the 3 same phase cables to their cutout, and that would work for fast EV charging? That would be great

Fast EV charging Would phase converters cost several thousand pounds?
