Hi Michael, Following our site visit and recent conversations please find below our update. The new scheme with off-loading and erection of sections A-D from the Heytrhop College side. After sections A-D is erected the steel will be erected from the Gantry Crane. The cost for the design, fabrication and installation of the steelwork based on this methodology will know be £6,727,325. Please note the following:
This includes for installation during Network Rail engineering possession hours. The installation period will now however increase to 88 days from 66 days due to the use of the gantry crane and engineering hours. We have included for 1nr 250t mobile crane for off-loading, assembly and installation of sections A-D and loading of the gantry crane for all other sections. We have excluded the supply and installation of the gantry crane at the current time Task lighting is assumed to be provided by others Included all mobile access plant and telehandler for assembly We have excluded the concrete tow from the bottom of the steel beams
All other costs will be as per the below table. I am sorry for the delay to the issuing of this information. Please let me know of any further information that I can assist you with. Kind regards Tom
From: Tom Marsden Sent: 09 October 2019 16:20 To: Michael Hughes <Michael.Hughes@cast-consultancy.com> Subject: RE: Heythrop College : Steel Beam Cost to Deck Construction Hi Michael, Please see below a high-level cost plan for the structural steelwork transfer deck for Heythrop College. Given the level of detail, we have partly based these rates on the Vine Street transfer deck that we have recently constructed for Balfour Beatty. I have set this cost plan out as a live document using the quantities you have provided which can be amended as the scheme develops. I have where possible put rates against all of the options you have outlines and added in other items such as allowances for connections/splices and fire protection where appropriate. Please note, that we have assumed that we will install the steelwork using mobile cranes.
Points to note are as follows: We have allowed additional tonnage for all spice plates and connections – Total assumed tonnage is now ??? Including all lifting brackets Included all required mobile craneage – currently assumed 2x 350t mobile and 1x 55t mobile Included all mobile access plant and telehandler for assembly We have allowed for an assembly team to splice the beams in the laydown area We have allowed for an installation team to install the fully assembled beams into position We need to understand logistics and installation sequencing further so for the time being we have not allowed for the restricted working during
possession periods. This can be discussed tomorrow and I will then revise our cost plan to suit. We have currently excluded the pre-cast planks – Again, this is an item that we can discuss at our meeting tomorrow.
I trust this information is of suitable assistance for budgetary purposes. I look forward to meeting you tomorrow to discuss this project further. Please let me know of anything further that you require. Kind regards Tom

It also worth going to the google maps link for the site here which to understand site locaruib: https://www.google.com/maps/place/Heythrop+College/@51.4995765,-0.1901629,18z/data=!4m8!1m2!2m1!1sheythrop+college!3m4!1s0x48760ff67cc42891:0x96612b1fbdef8ee4!8m2!3d51.4992505!4d- 0.1903322 I have attached Arup’s steel I Beam option, the document shows the steels for the deck construction are generally 2.2m deep, 3.5m spacing, up to 24m long at some locations of the deck and ranging between 18t and 37t in weight. Due to the access restraints of the site (see image below) we would need to bring the steels into site in 3 sections and spliced in the land directly adjacent to the railway.
We have measured just over 1850t of steel for the new deck construction with crane provision measured separately. As discussed the proposal is to form a concrete to the bottom web of the steel to either place formwork or pre-cast slabs on the bottom to form the soffit of the railway line, this concrete work would likely need to take place post splicing of the beam on site. We have captured this concrete toe within the rate of the steel but if it is easier for you to split this cost then we can combine for comparison to our cost plan. If you have any questions please give us a call.

From: Steve Attwood To: Michael Hughes Cc: Anthony.Lucas@keller.co.uk; "Davison, Shaun" Subject: RE: Kensington High Street OSD - Heythrop College - preliminary piling layout Date: 30 September 2019 11:36:04 Attachments: ARP-SK037revA Preliminary track pile layout.pdf
ARP-SK035 Mini pile options LUL.PDF
Good morning Michael, Further to our email dated 13.09.2019 and our telephone conversation this morning I confirm the following factors which were considered in generating the typical high end unit pile rate of £7,500 with Arup as follows:
A. The very difficult access for the piling operation installed into the deep operational railway cutting.
B. Installation of piles in a narrow corridors surrounded by hoardings adjacent to live rail traffic. The corresponding limitation of the size of piling rigs to operate in these circumstances i.e. requirement for specialist high capacity mini piling rigs.
C. The need to service the rigs with materials and remove the boring arisings in this narrow working environment will limit piling production
D. The need for 450mm nominal diameter piles ( in lieu of 300mm diameter piles which would normally be appropriate for the prevailing working conditions) to provide piles of sufficient stiffness to resist the specified horizontal rail impact loading .
E. The need to reinforce the piles with as substantial circular hollow section or sacrificial casing necessary to provide the piles with the requisite bending capacity.
We would also confirm that we frequently are installing high capacity stage bored mini piles not exceeding 300mm diameter in basements with limited headroom for unit piles rates in the range £4,000-5,000. The piles under consideration for Heythrop College have a significantly higher degree of difficulties associated with their construction and material content in the anticipated circumstances. We trust the forgoing will assist with the project assessment.
