1 Start-up

Identify scope of Points Heating.

Read Client Remit/CRD/MFR which provides brief commentary on the site under consideration.

Locate site on 5 mile plan and identify access points.

Locate site on Google maps.

Locate site on CAB ride video and try and determine location of existing assets.

Discuss access arrangement with Site Planner (Andy Hazell).

Use this time to visualize the site visit.

1.1 Arrange Site Visit

Site visits to be arranged only after a finalized Permanent Way Footprint is available (Except

when doing Grip 2 works).

Daytime surveys under Separated Zone conditions are preferred.

Night Time surveys only to be done if Daytime surveys impossible.

Ensure availability of personnel (i.e. yourself & Andy).

Attendance of the NR Project Engineer is preferred. Try to ensure that the site visit is arranged to

his/her convenience.

Arrange for Paperwork well in advance of site works (i.e. Task Brief & Safe System of Working

Document).

Using information in Section 1 & points above amend site works table to ensure everything

required is picked up on site.

Book a Pool Car in advance or use a hire car.

Carry a camera, notepad, pens, safety paperwork, Multimeter, Clampmeter to site.

Also carry A4 section print outs of the Permanent Way Site Layout drawings to easily mark-up on

site.

1.2 Site Visit

Arrive and undertake the site visit as planned in sections1 & 1.1 above.

Ensure all measurements are taken and all relevant assets are marked up on site.

Make notes and create a summary in word post the site visit as a record.

Upload photographs to folder 48 and make sure it has a date and name to it.



2 Form A

2.1 Document:

Use a previous Form A as a template. 5110144 LNW North Folder 51 and any of the site

subfolders is a good place to start.

Change headers, footers, titles to begin with and amend the Form A to suit the site.

Amend every section in line with what was observed/ measured on site and the scope.

The main focus of the Form A Is Approval in Principle: Is there enough power to supply the

renewed points, are there any space constraints, is the proposal feasible? At this stage your

document should be P01 (Preliminary).

2.2 CAD

2.2.1 Site Layout Drawing

Obtain latest & finalized footprint (Horizontal Layout) in CAD/Microstation format from

the PWay Team (ask the PM for the details of the person to speak to).

Liaise with Lucy to setup the drawing (CAD/Drawing folder), making sure that the drawing

covers the junction/renewals site and ask Lucy to print you a hard copy.

Mark-up the existing assets on site as per what you noted on site, and mark-up new items

(i.e. DNO Supply Cubicles, Points Heating Control Cubicles, Points Heating Transformers

and associated text to describe these).

Make sure that you also mark-up the trough route to show existing cable routes. Mark-up any new cable trough routes.

Give it to Lucy to CAD up and request her to print a copy once done.

Check the CADed up version against your mark-up and identify any discrepancies.

Give it back to Lucy to make any final amendments. At this stage your drawing should be

P01 (Preliminary).

2.2.2 Schematic

Use an existing Schematic from the 5110144 LNW North Folder 56.3 (Golborne for 1

DNO, 1PHCC, Lancaster for 2 DNOs,2 PHCCS, Bamfurlong/Acton Bridge for 1 DNO, 2

PHCCs, and Earlestown/Penrith for 3 DNOs,3PHCCs).

Modify the schematic to reflect the site specific DNO & Distribution characteristics, PHCC

connections and the type of point ends that are connected (based on photographs and

site notes.



Give it back to Lucy to make any final amendments and pdf. At this stage your drawing

should be P01 (Preliminary).



2.3 Form A Checking

Compile a pdf of the Form A, Site Layout, Schematic and print a copy for Andy Hill.

Make any necessary changes and send link (or pdf) to nominated checker and copy Andy into

all email interactions.

and Schematic drawings. Bind the document and fold the drawings.

Hand over the Form A to the PM/document controller and they will ensure that it is submitted

to the client. At this stage your drawing should be P01 (Preliminary).
