Construction Services Delivered End To End

Eight service lines covering everything from feasibility and design through construction, handover and long term maintenance.

Service Lines

Take one service or hand us the whole project. Either way it is the same team, the same supervision and the same reporting.

01

Design & Planning

Our design team translates your vision into detailed plans.

02

Construction Management

Expertly manage every aspect of your project.

03

Commercial Projects

Ensuring functionality, efficiency and adherence to all regulations.

04

Residential Projects

We create beautiful and functional living spaces.

05

Renovations & Remodeling

We handle all aspects of renovations and remodeling.

06

Project Management

Gain valuable insights and expert advice at any stage of your project.

Site clearing to start new construction.

Site Preparation

Most of what determines whether a project runs well happens before anything is built: clearing, levels, drainage and access. We plan that work properly, then supervise it, because everything above ground depends on it.

More about how we work

Process

Whichever service you engage, the process is the same and you always know which stage you are in.

Step 1

Consultation

We visit the site, listen to what you actually need and tell you honestly whether the idea and the budget fit together.

Step 2

Design and pricing

A written scope, a clear price and a programme with dates. What is included is stated plainly, so nothing is assumed.

Step 3

Construction

Work proceeds under a managed programme with supervised trades, staged inspections and a weekly report to you.

Step 4

Handover and aftercare

Snagging closed out, documentation handed over, warranties issued and a defects period where we come back if needed.

Not sure which service you need?

Describe the problem rather than the solution. We will tell you which route makes sense and what it realistically costs.

Market Segments

Aviation, wastewater, healthcare and residential. Each sector carries different requirements, different inspections and different consequences when something is done poorly.

Market Segments

The projects listed under each segment are work Sigma has delivered. If your sector is not listed, ask anyway.

Aviation

Hangars, terminal expansion and airport facilities, delivered to the access, security and operational constraints that live airfields impose.

  • Comair Aircraft Hangar
  • LPIA Expansion A, B and C
  • Marsh Harbour Airport

Waste Water

Wastewater treatment plants and associated infrastructure, where process requirements, containment and commissioning drive the programme.

  • St. Thomas WWTP
  • Club Med WWTP
  • Sandy Port WWTP

Healthcare

Clinical environments demand specific finishes, separations and services. We build to those requirements and document every stage for compliance.

  • Doctors Hospital CCSD
  • St. Elizabeth Medical Center

Residential

Private homes and estate properties in established Bahamian communities, built with the finish quality and discretion private clients expect.

  • Chub Cay
  • Lyford Cay
  • Old Fort Bay
Wider Capability

Capability beyond the named segments above, applied under the same construction management discipline.

Commercial & Institutional

Offices, retail, community facilities and mixed use buildings, delivered under the same construction management discipline.

Renovation & Fit Out

Refurbishment, remodelling and restoration of existing buildings, including work carried out around occupied properties.

Storm Damage & Reinstatement

Assessment, documentation and replacement of hurricane damaged structures, from inspection through to reinstatement.

Approach
  • Live environments

    Hotels, clinics and shops rarely close for construction. We phase work, screen it and run out of hours shifts where the operation demands it.

  • Inspection regimes

    Healthcare, education and public work carry inspection requirements that must be planned into the programme, not discovered during it.

  • Operational loading

    Industrial slabs, yards and access routes are engineered for the equipment that will actually use them, not for a generic specification.

  • Marine exposure

    Waterfront work is specified for permanent salt exposure. Fixings, reinforcement cover and coatings are chosen accordingly.

Building for a sector with strict requirements?

Send the specification. We will confirm what we can meet and how we would evidence it.

Safety And Quality Are Not Optional Extras

Everybody who arrives on a Sigma site goes home in the same condition, and nothing gets covered up before it has been inspected. Both of those are conditions of working with us.

Safety

Construction is one of the most dangerous industries in the world, and most serious incidents trace back to something that was known about and tolerated. Our approach is to remove the tolerance. Supervisors are authorised to stop work, and are expected to.

  • Site risk assessment

    Every project starts with a written risk assessment covering access, work at height, plant movement, services and public interface.

  • Method statements

    High risk activities proceed only against an agreed method statement that the working crew has read and understood.

  • Daily briefings

    Every crew starts the day with a short briefing on the tasks ahead, the hazards involved and the controls in place.

  • Personal protective equipment

    Hard hats, high visibility clothing, eye protection and safety footwear are mandatory on all active sites, for staff and visitors alike.

  • Plant and equipment control

    Plant is inspected and maintained on a schedule, and operated only by trained and authorised personnel.

  • Incident reporting

    Every incident and near miss is recorded, investigated and used to change how we work. Near misses matter as much as injuries.

Quality

Quality is not a final inspection. It is a series of hold points where work stops, gets checked and gets signed off before the next trade covers it.

  • Inspection hold points

    Work stops for inspection at defined stages: setting out, reinforcement, before concrete pours, before closing walls and at completion.

  • Materials verification

    Materials are checked against specification on delivery, with certificates retained for structural and concrete elements.

  • Supervisor sign off

    No element is covered, closed or paid for until a superintendent has inspected and signed it off.

  • Defect logging

    Defects are logged with photographs, assigned to a trade with a date, and tracked until closed.

  • Handover documentation

    Clients receive as built information, warranties, operating instructions and the full inspection record at completion.

Assessment

We carry out site inspections to identify hurricane damaged structures for repair or replacement, and to record the condition of existing assets before work is scoped. Findings are documented with photography so owners can see exactly what was found and why it matters.

Environment

We build on islands with limited land, limited landfill and a coastline that everything eventually drains into. That shapes how we run a site.

Waste management

Site waste is separated where practical and disposed of through licensed routes. Nothing leaves a Sigma site informally.

Water and runoff control

Silt, runoff and wash water are controlled so construction does not carry material into drainage systems or the sea.

Material durability

Specifying for salt air and humidity from the start reduces replacement cycles, which is the most meaningful environmental saving in island construction.

Local sourcing

Bahamian suppliers and Bahamian labour wherever the specification allows, keeping value in the local economy.

Commitments

The practices applied on every Sigma project, from preconstruction planning through to closeout.

Preconstruction Planning

Potential risks, sequencing requirements and project controls are reviewed before work begins.

Site Specific Safety Planning

Safety considerations are incorporated into planning, coordination and day to day site supervision.

Quality Control Reviews

Work is reviewed against project requirements, approved documentation and established quality expectations.

Subcontractor Coordination

Trades and project participants are coordinated to support safe, organized and efficient execution.

Need our safety documentation for a project?

Ask and we will provide the relevant project documentation and a project specific method statement before work begins.
