BIHE / University of Greater Manchester Evolution

The institution has undergone several name changes and status upgrades that affected the delivery of the HND: 

  • 1982: BIHE was formed through the merger of Bolton Institute of Technology and Bolton College of Education (Technical).
  • 1992: The Institute was granted the power to award taught degrees.
  • 2004/2005: BIHE achieved full university status, becoming the University of Bolton.
  • 2024: The university rebranded as the University of Greater Manchester

HND Computer Studies: Detailed Timeline

The course traditionally follows a two-year full-time or three-year part-time structure. 

Year 1: Foundations (HE4 Level)

The first year focuses on establishing core technical and business knowledge. In many versions of the Bolton curriculum, Year 1 is common across several computing programmes to allow for flexible progression.

    • Introduction to Programming: Developing fundamental coding logic.
    • Computer Platforms & Systems Architecture: Understanding the hardware and software environments.
    • Information Systems & Databases: The basics of data management.
    • Website Production & Networking Fundamentals: Introduction to web technologies and connectivity.
    • Quantitative Techniques & Business Studies: Integrating mathematical and commercial contexts. 

Year 2: Specialisation (HE5 Level)

The second year shifts toward advanced application, systems analysis, and professional practice. 

  • Advanced Modules:
    • Systems Analysis & Design: Producing system requirements and user interface specifications.
    • Programming Methodology: Moving into more complex application development.
    • Business Information Systems: Exploring how IT supports organizational requirements.
    • Database Design: Implementing industry-standard database packages.
  • Final Year Project: A major 20-credit core project where students investigate a specific field and apply their cumulative skills to a real-world scenario. 

Progression and Modern Standards

  • Academic Standing: Completion of the HND is equivalent to the first two years of a Bachelor’s degree (Level 5).
  • Degree Top-Up: Successful HND graduates can typically proceed directly into the final year (Level 6) of the BSc (Hons) Computer Science or BSc (Hons) Computing at Bolton.

Barclays locations worked at for Tandem HP NonStop code development

Radbroke Hall is a 64-acre “Innovation Campus” in Cheshire that serves as the global technology and operations hub for Barclays. Originally built as a French chateau-style private residence in 1917, it transitioned through use by a nuclear research group before Barclays acquired it in 1972. Today, it employs approximately 4,000–6,500 staff and has been the development site for pioneering banking technology, including the first ATMs, debit cards, and mobile banking platforms. 

Radbroke Hall History Timeline

Era 1: Private Residence (1914–1956)

  • 1914: Construction begins on the Hall for Manchester textile manufacturer Claude Hardy and his wife Olga.

  • 1917: The Hall is completed as a private residence.
  • 1920s–1930s: The Hall remains largely unoccupied during these decades. 

Era 2: Industrial & Nuclear Research (1956–1972)

  • 1956: The Hardy family sells the estate to The Nuclear Power Group.
  • 1956–1972: The site is used for nuclear energy research, with offices and a testing tower constructed on the grounds. 

Era 3: The Barclays Transformation (1972–1990s)

  • 1972: Barclays purchases the site from The Nuclear Power Group to reduce high rental costs in London.
  • 1972 (Relocation): Approximately 1,400 staff are relocated from London or hired locally; many find the move from London to the “rural North” a significant culture shock.
  • 1970s–1980s: The site begins its role as an IT hub, instrumental in developing the first cash machines (ATMs) and debit cards.
  • 1985: Barclays reorganises its UK and International banks into a single entity, further centralising tech and staff services at Radbroke. 

Era 4: Global Tech & Modernisation (2000s–Present)

  • Early 2000s: The campus leads the development of Barclays’ online and mobile banking applications.
  • 2012: Barclays celebrates the 40th anniversary of its presence at Radbroke Hall.
  • 2017: The original Hall building marks its 100th anniversary.
  • 2021: Barclays announces a major redevelopment plan to modernise the campus, including the demolition of older buildings (Kilburn, Lovelace, and Brooker Houses) to create a new central “town square” and “re-green” 80,000 sq. ft. of land.
  • 2024: Investment continues to transform Radbroke into a “world-class campus” focused on the future of work and advanced banking APIs.

Barclays House, located at 1 Wimborne Road, was a dominant fixture of the Poole skyline for 46 years. Originally built to decentralise Barclays Bank International operations from London, the nine-storey brutalist structure served as a major regional headquarters from 1976 until its closure in 2022. Following its vacancy, the building was earmarked for conversion into a residential complex featuring 362 apartments

Historical Overview

  • Purpose: The building was commissioned to move staff away from high London costs and boost local employment in Poole.
  • Architecture: Designed by Wilson, Mason and Partners, it features three interlinked octagonal/hexagonal towers in the brutalist style.
  • Landmark Features: A massive 14-foot aluminium eagle logo (the Barclays emblem) adorned the front of the building for decades. 

Detailed Timeline Breakdown
