Public Building Marble Façade and Natural Stone Applications

Public Building Marble Façade and Natural Stone — Sipahi Since 1989

Courthouses and Ministry of Justice Projects

Courthouses are among the leading categories of public building requiring both architectural prestige and high structural durability. Marble and granite façade cladding on courthouse buildings reflects the institution's dignified and trustworthy image, while interior flooring and staircase applications require low-maintenance stone types resistant to heavy visitor and staff traffic. Sipahi Marble provides natural stone solutions compliant with public building standards for courthouse projects, including entrance hall flooring, staircase treads, security checkpoint areas and exterior façade cladding. We work in coordination with architects and contractor teams on materials and application details that comply with the standard project types the Ministry of Justice specifies for courthouse buildings.

Municipality, Governorate and District Governorate Buildings

Local government public buildings such as the Sakarya Metropolitan Municipality, district municipalities, Sakarya Governorate and district governorate (kaymakamlık) service buildings are the public structures citizens interact with most frequently. Natural stone façade and interior applications in these public buildings serve a dual function: reflecting local identity while reinforcing institutional prestige. Sipahi Marble offers material recommendations that reflect Sakarya's local stone character for municipality and governorate building projects, while producing mechanical façade systems and flooring solutions that meet public building durability standards. The same quality standard and technical certification process apply to smaller-scale public buildings such as district governorate offices.

Public Hospital and City Hospital (Şehir Hastanesi) Projects

City hospitals are among the largest-scale public building investments Turkey has undertaken in recent years; natural stone applications in these projects must simultaneously satisfy hygiene, durability and aesthetic balance. Flooring in public hospital buildings is selected from granite and composite stone types with low porosity and easy disinfection properties; entrance hall and common-area façades favour marble and granite combinations that reflect institutional seriousness. Sipahi Marble provides low-maintenance natural stone solutions for public hospital and city hospital projects that meet the hygiene standards required for healthcare facilities.

National Education Investments — Schools, Dormitories, Universities

School construction by the Ministry of National Education, dormitory buildings under the Credit and Dormitories Institution (KYK), and campus investments by public universities are among the broad category of public building projects. Natural stone selection for these public buildings prioritises materials that withstand heavy student traffic, require low maintenance and offer long service life. For education-purpose public building projects such as schools, dormitories and university campuses, Sipahi Marble recommends granite-focused solutions for entrance halls, corridor flooring, staircase treads and exterior cladding — reducing the public building's long-term maintenance cost.

Public Tender Process and EKAP Compliance

The majority of public building projects proceed through tenders conducted via the Electronic Public Procurement Platform (EKAP). This process covers technical documentation prepared in compliance with tender specifications, submission of material quality certificates (TSE EN, ISO, CE), unit-price bid preparation and letter-of-guarantee procedures. Sipahi Marble maintains a corporate structure ready to meet the technical documentation, material samples and certification requirements demanded in public tender processes; we can support contractor firms in public building projects as a subcontractor or material supplier.

Material Standards and Certifications for Public Projects

Natural stone materials used in public building projects must be certified as compliant with specific technical standards. TS EN 13830 applies to façade applications, TS EN 12057 to marble slab production, and TS 10449 to granite materials; CE certification under the Construction Products Regulation (YMY) and ISO 9001 quality management system certification are also frequently required conditions in public building tenders. Sipahi Marble provides materials and certification support that comply with these standards demanded in public building projects.

Pricing and Payment Process for Public Projects

Pricing for public building projects is based on unit-price formation compliant with public tender regulations and the progress-payment (hakediş) system, requiring a more detailed cost breakdown than private-sector projects. Indicative 2027 price ranges are as follows: public building exterior marble/granite cladding, 3,500–8,000 TRY/m² (including mechanical anchoring system and engineering calculation); public building interior flooring and staircase applications, 2,500–6,000 TRY/m². Prices in the public segment run relatively higher than the private sector due to public-tender-specific factors such as additional certification, letter-of-guarantee costs and the progress-payment process. Sipahi Marble has the financial capacity to comply with the letter-of-guarantee and progress-payment process required in public building projects.
