Construction Services & Contracting | Fen Zemin & İnşaat

Fen Zemin & İnşaat provides construction services covering engineering coordination, contracting, project management, structural strengthening, steel construction, renovation and related building works.

Our construction activities are supported by a strong geotechnical engineering background.

This allows us to consider not only the superstructure, but also the interaction between the building, its foundations and the ground conditions beneath it.

Depending on project scope, Fen Zemin & İnşaat can be involved from technical evaluation and planning through site execution and construction coordination.

The exact scope is determined according to the project requirements.

Architectural and Engineering Services

Construction begins before work starts on site.

Architectural requirements, structural design, ground conditions, mechanical and electrical systems and construction methodology need to be coordinated before execution.

Fen Zemin & İnşaat evaluates projects as an integrated technical process.

Depending on the project, this may involve coordination between:

• architectural design,
• structural engineering,
• geotechnical engineering,
• mechanical systems,
• electrical systems,
• site execution.

The objective is to identify technical conflicts before they become construction problems.

Corporate and Private Contracting

Fen Zemin & İnşaat undertakes construction and contracting works for corporate and private clients depending on project scope.

Contracting services may include:

• mobilisation,
• site organisation,
• subcontractor coordination,
• material procurement,
• construction planning,
• quality control,
• progress monitoring,
• site management.

The construction method and programme are developed according to the project’s technical requirements and actual site conditions.

Construction Project Management

A construction project requires coordination between design, procurement, site production, cost and programme.

Project management may therefore include:

• work programme preparation,
• site planning,
• subcontractor coordination,
• procurement follow-up,
• progress control,
• technical coordination,
• quality monitoring,
• cost and schedule control.

The objective is to maintain consistency between the approved design and the work executed on site.

Consultancy and Construction Supervision

Depending on project requirements, Fen Zemin & İnşaat may provide technical consultancy and construction supervision services.

This scope can include review and monitoring of:

• design documents,
• construction methodology,
• site production,
• material compliance,
• progress,
• technical coordination,
• quality-control processes.

The role of consultancy is not simply to observe the construction.

It is to identify technical issues early and ensure that site decisions remain aligned with the project requirements.

Urban Redevelopment and Landowner-Contractor Projects

Urban redevelopment projects require coordination between technical, financial and construction considerations.

Existing structures, plot dimensions, planning restrictions, foundation conditions and neighbouring buildings can all affect the final project.

Fen Zemin & İnşaat evaluates redevelopment projects by considering:

• existing site conditions,
• demolition and excavation requirements,
• foundation and retaining systems,
• structural design,
• architectural planning,
• construction programme,
• site logistics.

In urban areas, foundation and excavation decisions can have a significant effect on both project cost and construction risk.

Structural Strengthening

Existing structures may require strengthening due to changes in use, structural deficiencies, renovation requirements or project-specific performance objectives.

Strengthening works should be based on engineering evaluation rather than a standard construction detail.

Depending on the project, structural strengthening may involve:

• reinforced concrete interventions,
• steel strengthening elements,
• foundation strengthening,
• local structural repairs,
• connection improvements.

Where foundation performance is part of the problem, geotechnical methods such as micropiles may also need to be considered.

Steel Construction

Fen Zemin & İnşaat provides steel construction applications depending on project requirements.

Steel systems may be used for:

• structural frames,
• industrial structures,
• strengthening works,
• secondary structural systems,
• project-specific steel assemblies.

Steel construction requires accurate fabrication, connection detailing and site erection planning.

The structural system, connection details and installation sequence should therefore be coordinated before fabrication begins.

Steel Structural Strengthening

Steel members can also be used to strengthen existing reinforced concrete or steel structures.

Possible applications may include:

• strengthening beams or columns,
• adding steel frames,
• local reinforcement,
• load-transfer improvements,
• project-specific support systems.

The strengthening method should be determined from structural analysis and existing-building conditions.

Renovation and Interior Construction

Renovation projects can involve much more than architectural finishes.

Changes to walls, floors, ceilings, mechanical systems or electrical infrastructure may affect the existing building.

Fen Zemin & İnşaat evaluates renovation works according to the technical scope of the project.

Depending on requirements, works may include:

• demolition and preparation,
• interior construction,
• partition walls,
• suspended ceilings,
• floor and wall finishes,
• structural modifications,
• mechanical coordination,
• electrical coordination.

Where structural intervention is required, the work should be coordinated with the relevant engineering design.

Mechanical and Electrical Coordination

Building construction requires coordination between architectural, structural, mechanical and electrical systems.

Late changes to service routes can create conflicts with beams, slabs, structural walls or architectural spaces.

For this reason, mechanical and electrical requirements should be considered during construction planning rather than after structural works are completed.

Fen Zemin & İnşaat coordinates these systems according to project scope and site requirements.

Why Ground Conditions Matter in Construction Projects

The visible building is only one part of the construction system.

The structure transfers its loads into the ground through its foundation.

For this reason, ground conditions can affect:

• foundation selection,
• excavation methodology,
• retaining systems,
• basement construction,
• groundwater control,
• settlement,
• construction programme.

Fen Zemin & İnşaat’s geotechnical background provides an additional perspective in projects where the foundation and ground conditions play an important role.

Construction and Geotechnical Engineering Together

Some projects require construction and geotechnical works to be planned as one coordinated process.

A deep basement may require a bored pile retaining wall and ground anchors before structural construction begins.

A weak ground profile may require jet grouting or another ground improvement method before foundation works.

An existing structure may require micropiles as part of a strengthening project.

In these situations, the geotechnical system directly affects the construction programme.

Fen Zemin & İnşaat evaluates these interfaces during project planning.

How Do We Evaluate a Construction Project?

The first stage is to understand the project scope.

Where available, we review:

• architectural drawings,
• structural drawings,
• geotechnical information,
• project specifications,
• quantities,
• site location,
• existing-building information,
• construction programme.

Site conditions are then assessed.

Important factors may include:

• access,
• neighbouring buildings,
• working area,
• storage areas,
• material logistics,
• excavation requirements,
• existing utilities.

The objective is to establish a construction approach that is technically feasible under the actual site conditions.

Design Coordination Before Construction

Construction problems often result from conflicts between different disciplines.

For example:

• an architectural opening may conflict with a structural element,
• a mechanical route may pass through a beam,
• an excavation may extend close to a neighbouring foundation,
• foundation construction may require equipment that cannot access the site.

Design coordination before construction helps identify these issues early.

Fen Zemin & İnşaat considers constructability as part of project planning.

Site Management and Construction Coordination

Effective site management requires more than supervision of individual activities.

Different trades and subcontractors must work in the correct sequence.

Construction coordination may include:

• site mobilisation,
• work-area planning,
• material deliveries,
• subcontractor sequencing,
• inspection points,
• progress tracking,
• site safety coordination.

Poor sequencing can result in rework, delays and additional cost.

For this reason, site organisation is treated as part of the construction method.

Construction Quality Control

Quality control begins with understanding the project requirements.

Depending on the construction scope, quality control may include:

• review of materials,
• inspection of workmanship,
• dimensional checks,
• reinforcement inspection,
• concrete records,
• structural connection checks,
• site documentation.

The appropriate controls depend on the type of work being performed.

The aim is to identify deviations before they affect later construction stages.

Construction Cost Factors

Construction cost cannot be determined reliably from floor area alone.

The total cost may be affected by:

• structural system,
• foundation type,
• excavation requirements,
• ground conditions,
• architectural specifications,
• material quality,
• mechanical and electrical systems,
• project location,
• site access,
• construction programme.

Two buildings with the same gross floor area may therefore have very different construction costs.

A meaningful cost assessment requires review of the actual project scope.

Project Programme and Construction Planning

The construction programme should reflect the sequence in which the project can actually be built.

For example, deep excavation and retaining works may need to be completed before basement construction begins.

Structural works may need to reach a defined level before architectural and mechanical activities can proceed efficiently.

Procurement lead times can also affect the programme.

Fen Zemin & İnşaat evaluates site production and technical dependencies together when preparing or reviewing construction planning.
