Form of Contract: NEC3 Engineering and construction contract April 2013

Procurement type: Two Stage

Contract period:  57 weeks

Size: 9290m2

As part of their ‘Restoration and Renewal Programme’ the client needed to move lots of staff members from their existing accommodation.

The refurbishment of this new space was to allow over 1000 member their staff to relocate there. The existing building occupied Levels 11 and 20 with Levels 1 to 10 offered as high standard Cat A. This 10 floor Design and Build Cat B office fit out comprised primarily of a new office, collaboration and ancillary spaces on Levels 3 to 10 with catering and meeting areas situated on Levels 1 and 2.

The Challenge

Integrating client instructed variations
ISG integrated upwards of 100 client instructed variations into the project.

Working in occupation
Works were carried out whilst the upper floors were in occupation.

High level of security
There were secure areas on every floor with CTC clearance requirements which meant ISG had to meet stringent SR requirements.

Working in a global Pandemic
Works were carried out in the midst of the Covid-19 global pandemic.

Fast track programme
The construction programme ran to a duration of just 24 weeks

The Solution

Integrating client instructed variations
ISG collaborated early BDP which was essential to allow alternative compliant design options and opportunities with increased budget certainty. ISG hosted workshops with the client and project team to incorporate instructed changes without negatively impacting the programme.

Working in occupation
Early engagement with incoming government departments was key; ISG held coordination workshops with the client’s in-house design team, data teams, security and maintenance teams, and catering teams. The phased programme was determined by incoming client direct contractors, and included early access and handover of the IT server and hub comms rooms 2 weeks before handover. To mitigate disruption to the existing building users, Westminster City Council, ISG held regular meetings to ensure minimal impact caused by their presence. ISG controlled more than 200 operatives using labour histograms and short interval controls with floor by floor close out programmes as part of our soft landings phasing strategy.

High level of security
For information security and due to the secure nature of the client and works, ISG integrated two document controllers into the team to manage the handling of the three doc-hosting systems; Aconex downstream to our supply chain, Business Collaborator, the client’s doc-hosting system and Conject for the NEC Contract management. Level 7 was highly secure, so ISG engaged with CPNI standards to achieve SR3 levels. ISG implemented early action of CTC clearance to ensure workers were security compliant for delivery. The team engaged at tender stage with government recommended subcontractors and incorporated their specialist programmes into our master programme.

Working in a global Pandemic
ISG followed strict Covid-19 protocols, complying with CLC and SOP guidelines. We enacted safety measures on site such as temperature testing, and 2 metre social distancing ensure the safety of the team, client and stakeholders.

Fast track programme
Production of a tender event schedule alongside programme enabled critical path analysis covering design release, labour and plan resource requirements, material procurement and security screening.  This ensured timely procurement and us the opportunity to plan resources to meet the programme. Long lead items were prioritised, we held workshops with our supply chain and the professional team to agree these elements of the designs quicker allowing early orders to be placed to assure on time delivery. In the last 8 weeks of the programme, the team optimised outputs using evenings and weekends to complete on time.

The Results

– ISG’s flexibility ensured client instructed changes were made without delay to the programme

– Working in occupation we received zero complaints from building occupants caused by our presence

– ISG met the client’s stringent security measures, and ensured our supply chain did the same

– ISG’s industry leading Covid-19 strategy ensured the works were completed on time, in a safe manner

– Fast track programme was successfully delivered with stringent programme analysis and evening and weekend works
