Day One

The project starts here.
The first 48 hours after award decide whether mobilisation is calm or chaotic. Award Intake captures the contract terms, programme anchors, stakeholder map and document control structure — before the first specification line is written.

SCOPE RECONCILIATION

Tender → Award Reconciliation

What changed between the tender we submitted and the contract we were awarded. Captured before mobilisation so every downstream output uses the awarded scope, not the tendered scope.

As Tendered £1,447,200 Bidroom submission · 14 March 2026

  • = Strip-out — L4, L5, L6 (existing fit-out) Removal of legacy partitions, floor finishes, ceilings, services drops. Make safe and protect.
  • = Cat-B build — partitions, joinery, finishes, AV, FF&E coordination Per tender drawing pack TP-NG-001 to 047 issued 27 Feb 2026.
  • = M&E modifications — supplementary cooling, lighting, power, data Cat-A landlord baseline retained. Tenant-specific augmentation only.
  • ~ Workplace AV — full design, supply & install Tendered as fully designed scope at £52,000.
  • Tenant move-coordination & data migration Tendered at £18,500. Excluded post-tender — moved to tenant-direct contract.
  • = Building services commissioning & T&C Including BCO sign-off, fire alarm reverification, smoke ventilation rebalancing.

As Awarded £1,418,650 Contract sealed · 1 May 2026 · −£28,550 vs tendered

  • = Strip-out — L4, L5, L6 (existing fit-out) Unchanged. Carried at tendered rate.
  • = Cat-B build — partitions, joinery, finishes, AV, FF&E coordination Unchanged scope. Quantities re-measured during PCSA — minor net increase £4,200.
  • = M&E modifications — supplementary cooling, lighting, power, data Unchanged.
  • ~ Workplace AV — provisional sum Restructured as £40,000 provisional sum. Tenant to confirm AV scope post-award (RFI NG-014).
  • Tenant move-coordination & data migration — REMOVED Out of scope. Excluded per CA Letter of Intent dated 24 Apr 2026.
  • + L6 reception joinery — additional provisional sum Added at award. £24,000 prov sum. Final design subject to tenant review.
  • = Building services commissioning & T&C Unchanged.
Movement Item Tendered Awarded Δ
Held Strip-out — L4/L5/L6 £86,400 £86,400 £0
Re-measured Cat-B partitions & doors £238,500 £242,700 +£4,200
Held Joinery — meeting suites & tea points £162,800 £162,800 £0
Restructured Workplace AV £52,000 £40,000 −£12,000
Added L6 reception joinery (PS) £24,000 +£24,000
Removed Move-coordination / data migration £18,500 −£18,500
Re-measured M&E supplementary works £284,300 £280,050 −£4,250
Held Finishes & flooring £196,400 £196,400 £0
Held Commissioning & T&C £42,300 £42,300 £0
Held Prelims, OH&P, contingency £366,000 £344,000 −£22,000
CONTRACT SUM (excl. VAT) £1,447,200 £1,418,650 −£28,550

Net movement of −£28,550 (1.97%) accepted by Built AI commercial team on 24 Apr 2026. Movement is non-margin-eroding: the −£18,500 removal eliminates third-party scope risk; the −£12,000 AV restructure converts fixed scope into a reimbursable provisional sum. Net upside on prelims of £22,000 reflects shorter pre-con duration agreed at award.

Communication protocol: technical queries route Built AI Design Manager → Architect or M&E Lead. Commercial queries route QS → Contract Administrator. Tenant approvals always via Cushman Workplace, never direct to Wexley & Crowne. Building access matters route via Building Manager during pre-con; transition to site-based PM at mobilisation.

SITE WORKING HOURS
07:30 — 18:00
Mon-Fri only. No weekend working without 5 WD notice + supplementary security cover.
NOISY WORKS RESTRICTION
10:00 — 16:00
Adjacent floors L1-L3 occupied. Drilling, cutting, demolition outside this window prohibited.
DELIVERY ACCESS
Goods Lift — Booked Slots
3-tonne capacity. Goods entry via Northgate Yard. Lift bookings via Building Manager — 48hr notice.
FLOOR-BY-FLOOR SEQUENCE
L6 → L5 → L4
Strip-out and build sequenced top-down. Concurrent working allowed once L6 first-fix complete.
ASBESTOS STATUS
Survey Clear
Refurbishment & Demolition Survey (May 2024). No ACMs in scope areas. Re-inspection if hidden voids opened.
FIRE STRATEGY
Building-wide — Restall
Compartmentation per Cat-A baseline. Tenant Cat-B alterations subject to fire engineer sign-off.
REF Long-lead Item Typical Lead Order-by Date Est. Value Owner
LL-01 Bespoke meeting suite joinery — fluted oak veneer, integrated AV cabling channels, full-height feature walls (L5 & L6) 10–12 weeks Wed 6 May 2026 £148,500 Pre-Con
LL-02 Workplace AV equipment — 14× displays, 6× video bars, ceiling mics, control system. Subject to RFI NG-014 closure. 8–10 weeks Wed 20 May 2026 £40,000 PS Tenant + Pre-Con
LL-03 Switchgear & sub-mains — 800A floor distribution boards, supplementary metering. Subject to landlord sub-main upgrade. 9–10 weeks Wed 13 May 2026 £56,200 Pre-Con
LL-04 Raised access flooring — replacement panels, tenant-specific cable management. Long-lead due to spec changes. 6–7 weeks Wed 27 May 2026 £38,400 Pre-Con

Order-by dates work back from the construction sequence with one week's float. Joinery (LL-01) is the binding constraint — slipping the order pushes L6 sectional handover and triggers LDs at £8,500/day per missed section.

RISK SNAPSHOT

Initial Risk Register — At Award

Eleven risks identified at intake. The register is live for the duration of the pre-con window — re-rated weekly, owner-tracked, escalated if RAG moves red.

REF Risk PROB IMP RAG Owner Mitigation
R-01
AV scope unresolved (RFI NG-014)
Tenant has not confirmed final AV requirement. £40k provisional sum at risk of overrun.
H M A D. Marchetti
+ Cushman
Workshop scheduled wk 2 with Wexley IT (N. Bramwell) and AV specialist. Target close: 15 May.
R-02
Joinery long-lead vs L6 sectional date
10-12wk joinery lead means order must be placed by 6 May. Any spec change post-order triggers cost & programme impact.
M H R S. Okafor Spec finalisation prioritised in Stage 02. Joinery enquiry pack issued wk 1. Sample sign-off wk 3.
R-03
Landlord sub-main capacity
Tenant electrical load exceeds Cat-A baseline. Landlord supplementary supply required — confirmed but not yet commissioned.
L H A A. Pereira
+ Lambourne Vance
Letter of comfort received from Halberd 18 Apr. M&E enquiry conditional on sub-main delivery confirmed wk 4.
R-04
Reception joinery design TBC
L6 reception added at award as £24k provisional sum. No design issued. Late design risks programme slip.
M M A A. Pereira Design intent workshop scheduled wk 2 with Trenholme + Cushman. Sample by wk 5. Manufacture by wk 7.
R-05
Sectional completion penalty exposure
£8,500/day LDs × 3 sections. Capped at 5% (£70,932). Schedule float minimal post-construction-start.
L H A R. Ashby Programme float review wk 4. Procurement tracker live by end Stage 04. Float test in Stage 05 QA gate.
R-06
Adjacent tenant occupancy — noise complaints
L1-L3 occupied by other tenants. Noisy works restricted to 10:00-16:00. Strip-out/concrete cutting risks complaints.
M M A D. Marchetti
+ Building Mgr
Site logistics plan wk 4. Tenant notification protocol agreed with Building Manager. Noise monitoring during demolition.
R-07
Supplementary cooling — plant access
FCU positions require ceiling plenum access. Some areas conflict with structural beams — re-design may be needed.
L M G A. Pereira
+ Lambourne Vance
Coordinated drawings expected wk 2. Site survey confirmation by Built AI M&E coordinator wk 3.
R-08
Tenant FF&E delivery sequencing
Tenant-direct FF&E delivery (workstations, soft seating) must integrate with Cat-B finishes programme.
M L G D. Marchetti
+ Cushman
Joint programme review with Cushman wk 5. Tenant deliveries to align with sectional handover dates.
R-09
Performance bond delivery
10% bond required within 10 WD of contract execution. Sentinel Brokers confirmed but not yet issued.
L L G R. Ashby Bond instruction sent to Sentinel 28 Apr. Issue confirmed for 7 May. CA notified.
R-10
CDM Principal Designer alignment
PD role held by Hadley Whitfield (also CA). Risk of conflict in dual role on design-related entitlement queries.
L M G A. Pereira Role boundaries agreed in writing wk 1. PD reports route distinct from CA correspondence.
R-11
Building Control approval timing
Cat-B alterations subject to BCO inspection. Inspection slots tighten in late summer — risk to L4 PC if missed.
L M G A. Pereira BCO pre-application meeting booked wk 3. Inspection schedule pre-agreed by end Stage 02.
RED RISKS
1
Joinery long-lead vs sectional date — actively mitigated wk 1.

Owner-allocated. Closure target by end Stage 03.
