As a leading specialist in architectural glazing, at OAG we support our clients throughout each project. From the earliest stages of design, through installation, and on to aftercare, we strive to deliver the best project management service in the industry. With all our experience, we know how to manage the risks and achieve beautifully finished glass structures.


Cost Plan Service

Accurate cost plan advice at early stages is vital with respect to managing client’s expectations with a project’s commercial viability in order to proceed with design, procurement and construction.

OAG’s team of business development managers and estimators engage with cost plan consultants and client teams, providing budget quotes for bespoke applications, very often based on similar formats used on completed projects.



The estimating process can be especially demanding with complex bespoke design projects and limited return timescales.

We communicate effectively during this process with our client’s commercial teams to ensure we understand and match their needs and also with our supply chain to resource specification compliancy and establish competitive market supply rates.

We provide compliant and structured tender bids by pricing design solutions with practical methodology, realistic detailed programmes and where possible, alternative specification value engineering proposals for a competitive edge.

Our business development managers take an active role in managing the bid process and engage with our client’s preconstruction teams to ensure the project enquiry is the right fit for our business model and to also provide a single point of contact.


Design and Engineering

With essential experience of working on complex and demanding projects our key strength lies at the heart of our design and engineering capabilities.

By actively encouraging early stage involvement with architects and consultants we create solutions that are buildable, commercially viable and maintain the architectural intent.

We understand that effective design management is critical to the success of complex construction projects. With the complexity of modern day materials, systems and solutions require more defined specialist knowledge, leading to the increasing importance of design input from trade-contractors.

By working with in-house structural engineers and using the latest technology including 3D rendering and BIM modelling, our design team is able to manage projects from initial concept and design through to installation.


Planning and Procurement

Our success is achieved through a collaborative approach to logistics planning, risk analysis and procurement.

We build our project schemes with a logical examination of what is required to get the desired outcome, on time and on budget.

Our project managers tackle this aspect of each project as early as possible in order to reduce risk and ensure we have the materials, staff and equipment on site when required.

We effectively communicate up and down stream during this vital phase to make sure everyone is in agreement and adheres with the project plan.


Project Management and Installation

Our project managers possess a complete understanding of the construction process and our goal is to complete our work on time, to the highest quality and within budget.

This is achieved through:
• effective project scheduling and establishing a project plan to determine the correct sequence of works
• monitoring progress in order to affect the timely completion of the project
• managing change events, such as design variations should they occur

Our project managers are accountable for the timing and duration of their planned activities and through regular team meetings on site keep all parties informed of the status of others’ activities that may precede or follow their work.

By adhering to these best practices we ensure a successful relationship between the contractor and subcontractors and thus, a successful completed project.

Each step requires dedication and commitment from each team member, and each step in the process is essential to a successful project outcome.
