C. Krohn-Lima Aestimationes Ltd was established to address a persistent weakness in the
construction and infrastructure market: the gap between commercially attractive tenders
and technically defensible estimates.
The practice was founded by a senior estimator with over a decade of experience
delivering priced work for complex civil engineering and infrastructure projects across
the UK. This experience spans highways, earthworks, drainage, utilities, reinforced
concrete, and multi-disciplinary enabling works, supporting projects from early design
development through competitive tender and into delivery.
Throughout this career, a consistent pattern emerged. Too often, estimates were driven
by speed, template pricing, or historic rates applied without sufficient interrogation
of scope, risk, or buildability. The result was predictable: under-priced work,
uncontrolled risk exposure, and reactive commercial management downstream.
C. Krohn-Lima Aestimationes Ltd was formed to do the opposite.
Our approach is rooted in first-principles estimating, technical clarity, and
disciplined commercial judgement. Every estimate is developed through systematic
analysis of drawings, specifications, constraints, and interfaces — not assumptions.
Risks and opportunities are identified, quantified, and clearly communicated, enabling
clients to bid with confidence and intent rather than optimism.
The company operates at the intersection of engineering understanding and commercial
strategy. This allows us to support informed decision-making: whether that is refining
scope prior to tender, stress-testing target costs, developing value engineering
options, or providing independent assurance on third-party pricing.
Underlying this approach is a strong analytical and behavioural foundation. The business
is led by an individual with a proven aptitude for complex problem-solving, structured
reasoning, and objective decision-making under uncertainty — traits essential to
high-quality estimating but often undervalued in the wider market.
C. Krohn-Lima Aestimationes Ltd is intentionally independent, technically rigorous, and
selective in the work it undertakes. We are not driven by volume; we are driven by
accuracy, transparency, and outcomes.
Our role is simple: to ensure that when our clients submit a price, it is defensible,
deliberate, and aligned with the realities of delivery."
Our Purpose
To raise the standard of cost certainty and commercial decision-making in civil
engineering by applying disciplined analysis, engineering understanding, and
transparent judgement to every commission we undertake.
We exist to ensure that prices are not merely competitive, but defensible —
technically, commercially, and contractually.
Our Approach
We provide specialist estimating, tender support, and value development services
grounded in first-principles thinking and real construction experience.
Our work is defined by rigorous interrogation of scope, method, risk, and
opportunity. We do not rely on assumptions, generic benchmarks, or untested
templates. Instead, we develop clear, auditable cost models that reflect how
projects are genuinely built, allowing clients to make informed decisions with
confidence at every pre-contract stage.
Our Principles
Our practice is guided by a small number of non-negotiable principles:
-
Technical Integrity – Every estimate must stand up to scrutiny, challenge, and delivery reality.
-
Commercial Clarity – Risks and opportunities are identified, quantified, and communicated without ambiguity.
-
Independence of Judgement – Advice is objective, evidence-led, and free from short-term bias.
-
Efficiency with Purpose – Speed is valued, but never at the expense of accuracy or understanding.
-
Long-Term Trust – We measure success by repeat engagement and enduring professional relationships.
Market Positioning & Commercial Strategy
We support construction businesses in strengthening their market position through structured commercial strategy, informed partner selection, and framework-aligned positioning. Our approach focuses on sustainable growth, improved bid selectivity, and access to appropriate commercial opportunities.
