Negotiated Tender

A smarter route to a successful build

We collaborate early with clients and design teams to refine costs, buildability and programme — ensuring value, transparency, and a smoother journey from start to finish.

The negotiated tender route allows you to appoint Karringtons based on trust, expertise, and performance, not just price. By joining the project team early, we help refine design, scope, and budgets to eliminate risk and deliver better value. Our proactive input during pre-construction ensures your project begins with clarity and ends with confidence.

Our Negotiated Tender process offers a structured, transparent, and efficient alternative. It allows early involvement, better planning, and shared ownership of the programme and budget.

Stage 3

Fixed-Price Contract

Once the design is finalised, we issue a fixed contract sum:

  • All-inclusive JCT fixed-price contract

  • Transparent scope and programme

  • Optional bolt-ons (e.g. AV, joinery, landscaping)

Outcome:

Certainty and clarity. No surprises.

Typical Scope

     Full works scope

     Procurement of specialists

     Contract admin

     Final warranties

Stage 2

Staged Pricing & Procurement

As the design progresses, we price elements in clearly defined packages:

  • Trade-by-trade cost breakdowns

  • Supplier-led validation and benchmarking

  • Value engineering aligned with programme needs

Outcome:

Collaborative decision-making with fullcost visibility and control.

Typical Scope

    Trade pricing

     Procurement of specialists

     Early site setup

Stage 1

Pre-Construction Services Agreement (PCSA)

We engage early and work alongside your design team to provide:​

  • Buildability reviews and programme advice

  • Procurement strategy and supplier recommendations

  • Budget management and value insight from the outset

Outcome:

Early momentum, reduced risk, and smoother coordination.

Typical Scope

     Design coordination

     Outline programme
