In November 2019 HFL Consulting was acquired by SLR, a global leader in environmental and advisory solutions.

SLR has a team of over 1800 professionals delivering advice and support from a network of offices across Europe, Asia-Pacific, Africa, Canada, the USA and Latin America. Our expanded service offering means we can provide a unique blend of leadership, management, consulting, engineering and training services to businesses of all sizes across the process and allied industries. We can draw on many more ‘in house’ skills and services, including process, civil and structural engineering, environmental permitting and compliance, air quality, flood risk, ecology, acoustics and wastewater treatment.

The Challenge

AL Control Laboratories is the largest independent laboratory in the UK.

Providing a range of solutions for the testing of soil, water, food, oil and air for contaminants or hazardous substances, the company is a global concern, with over 2,000 employees and 30 laboratories, servicing 11 European countries.

The UK site enlisted our help in improving its efficiency and output through the implementation of lean principles - leading to a leaner, fitter operation overall

The Solution

Identifying projects

Initially we provided support for four of the projects: Anions, Leachates, Semi-Volatile Organic Compounds (SVOC) e.g. water, and Volatile Organic Compounds (VOC).

Identifying roadblocks

We also worked with AL Control teams to identify roadblocks to future performance. For example, the high levels of re-testing taking place on one particular process was a fundamental element which would have prevented achievement of turnaround time targets, irrespective of all the other work undertaken.

Reducing hazards and risks

Another, potentially hazardous, factor identified and addressed by the team was that of samples from customers which compromised sample integrity and accuracy. Taking sub-samples of SVOC (w) and VOC allows the release of volatile compounds and compromises the safety of both people and the environment. The company has now increased the discipline of customers to provide separate samples for volatile tests and has educated its own staff not to take sub-samples.

Key Services

Business Diagnostics

Value Stream Mapping

Our engineers worked with key personnel across all relevant divisions to identify areas where processes could be improved. This was achieved through Value Stream Mapping activities for both the current and future states of the business. Particular emphasis was placed on the value-adding chemistry function versus the storage and movement of large batches of samples, which did not add value.

Lean Tools & Techniques

Problem Solving Tools

Using problem-solving tools and techniques, the team devised a very simple and inexpensive way of improving the test method and reducing variability. As a result the test reliability and accuracy was improved.

The Results

Our recommendations for the implementation of cellular processes and “single piece flow” have made a dramatic difference

Not only to turnaround times, which have improved from 38% to over 90% efficiency, but also to the layout of the laboratory itself. Now large areas of the building are empty and unused on account of there being less space required for the storage of samples. Instead of processing samples in large batches, a series of “mini” labs were created, which has meant that lead times have reduced by almost two-thirds – from 12 days to just over 3.5 days.

    Lead times have been reduced by almost two-thirds
  2. 02
    Turnaround times improved from 38% to over 90%

Our collaboration with AL Controls demonstrates that engaging employees at all levels and looking at processes in a different way can achieve tremendous results, both in terms of improved efficiency and staff support for sustainable business improvement programmes.
