Our Profile Boards have also been approved under our Project Kaiyo™ initiative as they have been manufactured from sustainable softwood timber. We recommend the Setting Out Peg for marking out temporary fencing lines and for hanging small notice signs. This product has been manufactured from sustainable softwood timber and is FSC certified. Firstly, Point W can be established by levelling across from the top of the gully at point K and allowing this 1.2 metre wide path to slope towards the gully by approximately 20mm, which is well within the 1:80 tolerance specified. So, point W is 20mm higher than Point K. Finally, we also offer Road Pin Protection Caps to help extend the life of steel road pins. They Prevent the deformation of road pins caused by excessive hammering. Please keep your proof of postage from the Post Office until we have confirmed that we have received your returned items.

The dimensions on the drawing states that the distance from the left hand edge of the front doorway (A), to the right hand corner of the property (C) is 7m + 3m = 10m. However, most landscape plans are drawn at a scale of 1:100 or greater, and will usually have an accuracy of around ±50mm. Our Fencing Pins are made of quality steel and are ideal for marking temporary fencing lines. They have approximately 8mm in diameter and 1370mm in length and feature a lamp hook for easy fastening of temporary fencing. On larger projects, automatic levels , theodolites, laser levels and even GPS are used to assist in the setting out, but there are some basic setting-out skills that require nothing more technical than a string line, an accurate spirit level, a tape measure, a handful of marker pegs, preferably 12mm steel road pins, and occasionally, a calculator, all of which should be readily available to most diy'ers. On the plan below, the marker pins have been positioned at 750mm centre to centre (c/c) along the arcs. Once in position, a taut string line can be fastened to the pins to create a line guide for the laying of the arcs.The level for point Q is established by pulling the line tight from L to Z and marking the pin at Q precisely where it touches, so that the line L-Z is what is referred to as a 'flat bone' - a single plane, not necessarily "flat level", ie: no fall in any direction but a consistent, steady fall in one direction. Anchor Station Markers provide and identify permanent survey stations with additional inserts in various colours available for increased visibility. Our high quality Ranging Poles are made from wood and steel and are ideal for marking out key points for measuring. They are used to mark the location of boundary lines, survey lines or other landmarks. In surveying, they also help mark or locate the points on the ground. You can also use pegs for marking or fixing road alignments, separating the boundaries of the properties. Putting this knowledge to practical use, we can see from the construction plan for the driveway that the shape of the drive is constructed from a series of rectangles and arcs. The most important line to be set-out is the left-hand edge of the driveway, line A-B marked in red on the drawing, which is perpendicular to the front of the house, and is aligned with the left-hand edge of the doorway. To establish this perpendicular, we use a 3-4-5 triangle.

static void sm_config_set_in_shift ( pio_sm_config *c, bool shift_right, bool autopush, uint push_threshold) The brief is to create a drive 7 metres wide, which is to align with the left hand edge of the front door, with a curved sweep on the right hand side to accommodate the double width garage and a smaller curve on the left hand side to tie in with a 1.2m wide pathway along the front of the property. static void sm_config_set_mov_status ( pio_sm_config *c, enum pio_mov_status_type status_sel, uint status_n)

To establish the 4.5m arc, a measurement is made along the face of the building, and the origin marked at 4.5m from C, ie at point G. The tape measure can now be anchored at point G, and used to scribe out the arc by swinging it around, from C towards H, marking in spray paint or similar. has been chosen as the length of the base line A-D because it is a multiple of 4, the largest side of the 3-4-5 triangle other than the hypotenuse. The base line is regarded as true (accurate - a genuinely straight line), and so the longest available edge, ie, the '4' always goes along the base line. For our right angled triangle we need to be as exact as possible with our measurements to ensure we get a true right angle at 90°, and not at 88° or 91°, so a measure is made along the front of the house, from the LH edge of the doorway at 'A' and a distance of 8m is marked with crayon or chalk at point D, just to the right of the garage door.

static void pio_set_irqn_source_enabled ( PIO pio, uint irq_index, enum pio_interrupt_source source, bool enabled) Insulated Fence Pin: Used with temporary fencing, our robust and highly visible non-conductive fencing pins are available in standard (plastic spike) or with a metal spike, more suitable for installation into tougher terrain. Supplied in lengths 600mm / 900mmIn the absence of an automatic or laser level, we can use a straight edged timber and a good spirit levelto transfer the level from point R to points L and M, and then add 35mm. Small boat levels, 200-300mm long are not usually accurate enough for this sort of work, and so we recommend a spirit level at least 1200mm in length to be accurate when transferring the level by means of a straight edged timber, 3 to 4 metres in length. However, it is obvious that even a 4m straight edge will not span the distance from R to L or M, and so we set up a temporary intermediate level. Using a straightedge and spirit level to transfer levels

We provide varying types of flags in different colours to out specific areas/objects and are a very cost effective way to help with general surveying tasks. For other type of marking out then wooden stakes work well and our road pins are perfect for concrete form work. void pio_sm_set_consecutive_pindirs ( PIO pio, uint sm, uint pin_base, uint pin_count, bool is_out) Now we have R, J and K established, the next critical levels to set are the high points on the driveway, on the break line L-M. We can measure that from the centre point of the break line L-M to the furthest gully, K, is approximately 10 metres. Using the standard 1:80 fall, we can calculate that the midpoint on line L-M needs to be...... UK Mainland excludes Northern Ireland, Scottish Highlands, Offshore Islands and the Channel Islands.We know that the gully at K is 90mm below R, so Points L and M need to be 125 - 90 = 35mm higher than point R, which means it would be 150mm - 35mm = 115mm below DPC level. When the surface of a pavement exhibits a change in gradient, this may also be reflected in the edgings or kerbs. Use a state machine to set the same pin direction for multiple consecutive pins for the PIO instance.
