Market Problems and Our Solutions

We understand that the construction market can be complex. Many clients face the same problems that lead to financial risks, delays, and poor quality.

Problems you face

Difficulty finding reliable contractors.

A deceptively low price often leads to incompetence and problems. Many construction companies leave projects without proper supervision, relying on a single crew and a foreman who rarely visits. This leads to norm violations and missed deadlines.

Lack of transparent pricing and financial risks.

Contractors may not account for all work or use cheap materials in their estimates. As a result, the final project cost unexpectedly increases, and construction is put on indefinite hold.

Poor construction quality.

In Indonesia, common problems include mold, cracks, and poor waterproofing. This often happens due to poor drawings, incomplete information for estimators and workers, as well as the use of cheap materials and failure to follow technologies. Workers on site may not have drawings, the necessary tools, or the skills to use them.

Our solutions

Our main goal is to ensure high quality and complete the project on time. We balance your wishes with our mission to build with quality.

A reliable partner with full control.

We don't rely on a single foreman. Our team includes specialized engineers, technical supervisors, estimators, procurement specialists, and cost controllers. We use modern ERP systems, video surveillance, and provide regular reports so you always know what's happening on site.

A clear estimate and protection of your interests.

We sign contracts that protect both parties. Before calculating the estimate, we audit the drawings and agree on all materials and technologies. Our goal is to provide you with an accurate and final project cost, so you avoid unexpected expenses.

Quality is our mission.

We meticulously work through all the details and nodes in the drawings, and use only proven brands and materials. Complete construction documentation is always available on site, and our employees are trained in the use of materials and modern equipment.

Services

We offer comprehensive solutions for your construction project, from idea to final implementation. We work with properties ranging from 500 to 100,000 m² and specialize in various types of projects.

Construction and Renovation

We act as both a contractor and a general contractor, providing a full range of services. Our experience covers various types of properties including **Renovation** (residential homes, cafes, restaurants, commercial spaces) and **Specialized work** (flat and usable rooftops, facades).

Design and Auditing

A correct project is the foundation of successful construction. Our team specializes in creating accurate and complete documentation through **Project development** (creating detailed drawings based on SNI standards) and **Drawing audit** (checking existing projects for errors and providing recommendations).

Project Management and Development

If you want to invest in real estate, we are ready to be your reliable partner. We offer full-cycle project management and development, which includes **Land search**, **Design and obtaining permits**, and **Construction and commissioning of the property**.

Construction Management

We act in your best interest, controlling all stages of construction if you work with another contractor. Our team provides **Technical supervision and quality control**, **Budget and schedule control**, and **Transparent reporting on the progress of work**.

Work Stages

We are convinced that the success of a construction project depends on strict adherence to every stage. Skipping or neglecting any stage can lead to schedule delays, budget overruns, and reduced quality. That's why we pay special attention to every step, starting with design.

Estimating project costs without detailed drawings is just guesswork. To avoid unpleasant surprises, you must first complete the design and approve all the details. This allows us to provide you with an accurate estimate and timeline, rather than an "open" cost that can increase during the process.
