What is Volumetric Modular?

Volumetric modular building is a construction method where accommodation is created using predetermined, self-supporting volumes or modules, manufactured offsite, in factories, under controlled conditions. The volumetric modular technique avoids many of the limiting factors and challenges faced by traditional construction methods in favour of a manufacturing and engineering orientated approach.


Totally Modular System

Totally Modular constructs a variety of buildings using a system know as Modular construction. Modular construction is a term used to describe the use of factory-produced building modules that are delivered to site and assembled as large volumetric components or as substantial elements of a building built using a combination of hot-rolled structural steel and LGS (light gauge steel).

With the Totally Modular system 97% of the building is finished within the factory environment ensuring program timing, quality and standards are maintained.

A range of external finishes including brickwork, render or cladding is mechanically fixed to the modules during the factory process achieving very high standards of finish. Windows and doors can also be installed during the factory process and are in accordance with accredited construction details to minimise heat loss and cold bridging contributing to excellent EPC ratings.

The System Specification

Totally Modular adopts a system that allows standard construction to around 5 storeys currently but has the capacity to develop a system to allow free-standing buildings to be developed much higher.

The principle system adopts 90 SHS corner posts with LGS beams and joists forming the skeleton frame with non load-bearing LGS infill walls (where required) effectively forming a volumetric module resembling a cuboid. Modules are stacked one above another with loads transferred down the SHS corner posts.

Insulation, membranes and lining boards are all fixed to the steel frame, internally and externally, to form a watertight, airtight and highly insulated fabric meeting and exceeding minimum building regulation requirements.

Electrics, plumbing, fixtures and fittings are also installed in the dry and clean factory environment by highly trained and skilled operatives.

Modules are transported to site by standard lorries and installed on to traditional foundation pads or ground screws using mobile cranes that lift the modules by eye bolts fixed to the corner posts and internal props. The modules are bolted to each other on site, joints sealed internally and externally and services are connected and tested.

BIM (Building Information Modelling)

Totally Modular uses Building Information Modelling (BIM) in the design and implementation of all of its House Types.

As standard we cover BIM level 2, which allows collaborative working between various CAD systems and multiple project-partners. However, the models can implement elements of performance from other BIM levels if required.

BIM makes it possible to detail the materials, cost model and maintenance modelling for every house type and allows for better collaboration between parties. There are benefits that BIM can bring to both off-site and traditional construction, with its ability to provide a visualisation of the proposed design allowing project managers to iron out any potential issues before work commences.
