    Bricking up car port planning permission

    As it looks to be part of a side extension, the planning permission for the extension could have a condition such as 'garage space not to be used other than for parking a car' or some such wording. But in the real world, its unlikely that the council would do anything, even if they got to find...

    Opening up wall with existing beam

    If its a standard box lintel (possibly Catnic?) it will be in their catalogue, giving the maximum load-bearing capacity for any given span. Its actually quite easy to work out the loads - your beam will be carrying part of the floor load, and possibly a wall above. There are standard tables with...

    Opening up wall with existing beam

    Is it a patented 'box' lintel, or a steel 'I' beam?

    Motorway Lights.

    So it seems it is intended as a way of saving the planet? More NetZero b******* then?

    Motorway Lights.

    Is it just me or has anyone noticed that more and more motorway lights seem to be off at night. I regularly drive up and down the M61 and M6 between South Lancashire and Glasgow. Granted most rural motorways are unlit but where complex junctions are situated, or when coming into urban areas, the...

    Unsupported 900mm opening in cavity wall

    It depends largely on the strength of the mortar, and also the care which has been taken to make the opening. Modern cement mortar can have good adhesion to the brick and may well hold up the triangle of brickwork across the opening. Older, lime mortars are not so reliable in this respect. It's...

    Architect drawings / costs

    You've hit the nail on the head here. On completion, Building Control are now sending out forms for the Principal Designer to confirm that the work complies with Building Regulations. It raises the question as what exactly is Building Control's job? In getting an architect or other professional...

    Chimney Stack Support in Loft: Bearing steels on 100mm internal spine wall?

    As cbde says, 152 x 152 x 23 would be more than adequate. Dont forget a thin (3mm) steel plate spanning from the top of the beam into a joint in the party wall. just to stop any lose bricks in the wythes from dropping down.

    External wall with no lintle

    If it is a shallow arch, it suggests that it was originally part of an opening in the rear wall, eg a door and adjoining narrow window? Can you not leave the arch as it is? - they are intended to be self-supporting. If you really feel you want to support it, a steel rectangular hollow section...

    Mid terrace front room, hallway floors + stud wall on heavily corroded steels

    Those steels will probably last until the Four Horsemen come riding in...

    Retrofitting restraint straps to joists in existing 9inch brick wall

    Have a look at this: https://link.springer.com/article/10.1617/s11527-020-01536-2 It's Italian research done about 5 years ago (in English) into direct pull-out tests of resin-fixed bolts into brickwork of various types (resin-fixed are far better that plastic-plugged screws). I've used this...

    Acrow, push-pull or bottlejack for supporting purlin for repair

    Woody is correct. Timber under long-term load is subject to 'creep', whereby the timber keeps its deflected shape. If you try to jack it straight, it might lift the rafters at the end. As it's not showing externally. just reinforce it as it is by any convenient method, adding extra timber or...

    Crown In Floor Due To RSJ

    If the joists are firmly supported off the bottom flange of the beam, or securely fixed to the web some way, the reason they have sheared is because the joists have shrunk. When they were installed, they will have had a relatively high moisture content, perhaps being stored uinder cover but...

    Moving doorway with lintel

    The purlin prop won't affect your new lintel; any load will just go down vertically against the new door jamb.
