Three Divisions.
One Group.

TH Civil, Consult Civil and Lemniscate Solar — three specialist divisions covering civil construction, engineering consultancy and renewable energy across Christchurch, Canterbury and New Zealand.

Civil Construction
TH Civil.
01

With 20+ staff and a fleet of new and modern machines, TH Civil handles the full breadth of civil construction. A strong focus on earthworks, three waters, roading, rail, structures, sub-divisions and all civil components within solar farms.

Between the team, there isn't a job they haven't done before — from large-scale earthworks to complex live-environment infrastructure delivery.

Engineering Consultancy
Consult Civil.
02

The consultancy side of the business. Specialising in providing project management, engineering services, engineer's representative, programme management, tendering, cost control and analysis — delivering positive outcomes for all parties involved.

Consult Civil brings independent, experienced oversight to complex civil projects — working with clients, contractors and councils to keep projects on time and on budget.

Renewable Energy
Lemniscate Solar.
03

The renewable energy division, specialising in EPC contracting and all aspects of solar development on behalf of developers — from civil works and piling through to panelling and commissioning.

Lemniscate Solar delivers complete solar farm packages with the full backing of BTB Group's civil construction capability through TH Civil.
