Preserving History, One Relocation at a Time:

Every museum object tells a story. When a gallery undergoes redevelopment, those stories must be protected, preserved, and prepared to continue inspiring future generations. This is where museum de‑installation and re‑installation come in. These highly specialised operations ensure priceless artefacts, specimens, and works of art are moved, stored, and re‑displayed with absolute care.

As museums evolve to reach wider audiences and create new experiences, the demand for precision‑led art logistics has grown. Complex redevelopment projects now require more than standard transport or packing. They call for expert coordination, conservation awareness, and technical ingenuity. Constantine has led many such operations, working with some of the UK’s most prestigious institutions to move national treasures safely and seamlessly.

What Is Museum De‑installation and Why Is It So Complex?

Museum de‑installation is the meticulous process of removing, packing, transporting, and re‑installing artefacts and displays, often within challenging environments. It requires detailed planning, specialised handling, and conservation‑grade materials to protect objects that may be centuries old or structurally fragile.

Each object presents unique risks. Some are heavy or awkwardly shaped, others are delicate or irreplaceable. Even small vibrations, temperature changes, or incorrect lifting techniques can cause damage. The process demands precise coordination between art technicians, conservators, and engineers, as well as careful documentation to ensure every piece is tracked throughout its journey.

From scaffolding design to reusable crating, every step must balance safety, preservation, and efficiency. At Constantine, these disciplines come together through decades of experience and technical mastery, ensuring collections remain secure throughout even the most complex relocations.

Case Study 1: Dismantling and Rehousing Dippy the Diplodocus

Dippy the Diplodocus has been a beloved figure at the Natural History Museum for over a century. When the time came for the 25‑metre cast skeleton to embark on a UK‑wide tour, Constantine was entrusted with its careful de‑installation and preparation for transport.

The project began with the design of a bespoke scaffold structure, providing safe access to every section of the dinosaur while maintaining stability throughout the process. Each bone was individually tagged, documented, and assessed with the museum’s conservation team before being removed.

Due to Dippy’s internal metal spine, the team faced the challenge of working around a long supporting pole that ran through the structure. Larger sections had to be lowered intact rather than dismantled into smaller fragments. Once each piece was safely detached, it was filled and wrapped with acid‑free tissue and Tyvek, then packed in conservation‑grade foam‑lined crates.

This careful approach ensured that Dippy’s delicate plaster components remained undamaged, while the thorough documentation guaranteed every piece could be reassembled with accuracy. The result was a flawless de‑installation that allowed one of Britain’s most iconic exhibits to travel the country, continuing to inspire new audiences without compromising its preservation.

Case Study 2: Heavyweight Engineering with a Delicate Touch

As part of the Natural History Museum’s once‑in‑a‑generation redevelopment, Constantine was tasked with the complex removal of the Blue Whale skeleton from the Mammal Hall ceiling. Weighing four tonnes and suspended high above ground level, the skeleton had not been moved since the 1930s.

The project began with careful planning and collaboration between our technical team and scaffold specialists. Access was limited, and the surrounding exhibits had to remain untouched. The skeleton’s vertebrae were threaded onto an iron spine, and each suspension cable had to be released in sequence.

The greatest challenge was the skull, weighing two tonnes. To remove it safely, our team designed a bespoke articulated lifting frame made from lightweight aluminium to minimise load on the scaffold structure. The skull had to be rotated 90 degrees mid-air to clear other suspended specimens. This was carried out slowly, under full control, with close monitoring for any structural reaction.

Once fully dismantled, the skeleton was packed and transported to fine art storage. It has since been reinstalled in Hintze Hall, suspended in a dynamic pose that now greets millions of visitors each year.

Case Study 3: The Horniman Walrus

In preparation for the Horniman Museum’s Nature + Love redevelopment, Constantine was appointed to de-install and relocate one of its most recognisable exhibits: the 200kg walrus. The work formed part of a wider reorganisation of the Natural History Gallery.

Our technicians used a tandem lift operation with two gantries to raise the walrus safely from its plinth. To avoid surface abrasion, all lifting slings were wrapped in Tyvek. A bespoke crate was built to mirror the original sloped display angle, preventing structural shift during storage. This design required precise calculations to navigate a height restriction on the object’s exit route, which was successfully resolved through detailed planning.

Alongside the walrus, five large dioramas and numerous specimens were repositioned internally for Anoxia treatment. These internal moves resembled a large‑scale three‑dimensional puzzle, managed with efficiency and care.

Once treated, items were either transferred to external storage or re-situated within the museum. Constantine’s team completed all handling and logistics within the timeframe, despite the constraints of working with historic displays and limited access routes.

How Constantine Ensures Safe Museum Object Relocations

Every museum relocation requires more than careful lifting. At Constantine, we use conservation‑grade packing materials and custom-built crates that meet the highest museum standards. Our exclusive partnership with Turtle crates allows us to offer reusable, high-performance packing for sensitive works.

Projects are led on-site by experienced technical managers who work closely with museum conservation teams. Each object is logged, tracked, and documented using our collection management system, ensuring complete traceability from start to finish.

Our team is trained to work within listed buildings, heritage settings, and restricted environments, adapting to the unique challenges each location presents.

Behind the Scenes: The Teamwork and Planning Involved

Every relocation begins with a site assessment and detailed planning phase. Our project managers and technical leads carry out risk evaluations, weight calculations, and handling plans tailored to each object.

Clear communication is maintained between all stakeholders, including conservators, curators, and building contractors. Our technicians are trained to museum standards, with the experience and judgement needed to carry out even the most complex operations with confidence.

FAQs

1. What does museum de-installation and re-installation include?

It’s the full process of removing objects or displays from a gallery, packing them to conservation standards, transporting them safely (and storing them if required), then reinstalling them ready for display. We plan the method and sequence in detail, especially where access is tight or the objects are fragile, heavy, or complex.

2. How do you reduce risk when objects are fragile, oversized, or heavy?

We start with a site assessment and a handling plan that’s specific to the object and the building. That can include scaffold design, gantries, and bespoke lifting frames where needed, plus conservation-grade materials to protect surfaces and reduce shock, vibration, and abrasion during every move and handover.

3. Do you produce condition reports and documentation throughout the project?

Yes. Documentation is central to de-installation work. We use structured recording (including photography where appropriate), clear sign-offs at key handovers, and object-level tracking so the location, movement history, and chain of custody stay transparent throughout the relocation.

4. Can you support temporary storage during refurbishments or phased gallery works?

Yes. Museum projects often need a secure holding phase between de-install and re-install. We can plan for short-term or longer-term storage so collections remain protected while building works, environmental commissioning, or gallery fit-out progresses.

5. What options do you offer for reusable crating and lower-waste packing?

Where suitable, we use reusable crating to reduce single-use materials without compromising protection. That includes our partnership with Turtle for reusable, high-performance crates, alongside other reusable crate options depending on the object, route, and handling profile.
