General contractor for officesOne point of responsibility for delivery

Detailed design documentation and delivery. One accountable team.

We combine design with general contracting for offices. We develop the concept into coordinated detailed design documentation, establish the budget and schedule, and then manage construction, testing, and inspections — as a single Design & Build process.

From concept to handover
Concept and detailed design documentation

We translate requirements and the concept into architectural and trade documentation. We verify design decisions against the budget and delivery conditions from the outset.

Pricing, schedule, and mobilisation

We prepare the pricing, schedule, delivery plan, logistics, and mobilisation in accordance with the office building's procedures.

Delivery and coordination

We contract subcontractors and deliveries, manage works, and control trade dependencies, costs, changes, and quality.

Inspections and handover

We manage testing, inspections, and defect rectification, and then hand over the space with as-built documentation and warranties.

Good design leads to good delivery. The same direction, from the first decision to inspection.

01 / 12General contractor responsibility

What does a general contractor for offices do?

Design and construction form one process.

We prepare detailed design documentation, coordinate trades and lead the delivery. The client receives a single point of reference for scope, budget, schedule and outcome.

  • Documentation for delivery
  • Pricing and schedule
  • Construction organisation
  • Coordination of trades
  • Quality control
  • Inspections and handover
Conference room with a long table, chairs and glazing
Preparation of office delivery

Concept developed into detailed design documentation

We start with the team's needs and the office concept — including one prepared earlier by the client. We develop it into detailed design documentation for architecture and building services. We verify the building's technical standard, the building manager's requirements, clashes and material decisions. The project prepared in this way becomes the basis for the budget, orders and the delivery led by Ecoffices.

Scope of responsibility
  • Detailed design documentation for architecture and coordination of trades
  • Definition of scope and boundaries of responsibility
  • Verification of the building manager's requirements
  • Pricing of office space delivery
  • Schedule of works, decisions and deliveries
  • Mobilisation and construction logistics plan
Outcome

A clear scope, a realistic schedule and a proposal ready for the start of delivery.

Office delivery in Warsaw led by Ecoffices as the general contractor
Organisation and delivery of works

Construction organisation and coordination of trades

We contract subcontractors and deliveries, prepare mobilisation and lead the delivery of office space according to a single schedule. We coordinate dependencies between construction works, finishing works, HVAC, electrical, sanitary, fire protection and telecommunication building services. We supervise the sequence of works, concealed works, material decisions, scope changes and ongoing agreements with the client and the office building administration.

Scope of responsibility
  • Mobilisation, protection and construction logistics
  • Construction and finishing works
  • HVAC, electrical and sanitary building services
  • fire alarm, BMS, LAN and access control
  • Coordination of subcontractors and deliveries
  • Control of schedule, costs and changes
Outcome

Coordinated office delivery without shifting responsibility between independent contractors.

Quality control, inspections and handover

Quality control and handover of the space

Quality control is carried out throughout the entire project, not just at the end. We verify concealed works, conduct inter-trade inspections, tests, measurements and building services adjustments. We coordinate the rectification of defects, compile records, as-built documentation, instructions and warranties, and then hand over a verified and documented office to the client.

Scope of responsibility
  • Quality control and inspection of concealed works
  • Tests, measurements and building services adjustments
  • Technical and inter-trade inspections
  • Snagging and coordination of defect rectification
  • As-built documentation and records
  • Handover of the space and warranties
Outcome

A ready, verified and documented office handed over under the single responsibility of the general contractor.

The general contractor for office spaces is responsible for the joint outcome of the entire delivery. The client receives a single scope, single coordination of trades and a single handover of the finished office.

02 / 12Project entry point

Every office starts from a different point.

We can enter the general contracting process at three different stages: with an approved interior concept, with an initial layout and a list of requirements, or from an empty space.

First we organise the scope, check the building’s technical conditions and identify the decisions that affect cost and programme. We then develop the detailed design, coordinate architecture and building services, prepare the budget and schedule, and after approval manage the works through inspections and handover. The client has one team responsible for moving the project from assumptions to a finished office.

Regardless of the entry point, before work begins we define the scope of general contracting, the division of responsibilities between the client and the building manager, the material standard, the completion deadline, and the rules for approving and settling changes.

03 / 12Detailed design documentation

Detailed design documentation unites all trades.

The concept shows the direction.

Detailed design documentation specifies how to realise it. We check eight areas together so that decisions regarding walls, building services, materials, and furnishings create a coherent office design.

8 areas. One complete scope.

Select the area and check what we verify before pricing.

04 / 12Mobilisation and start

Preparation of the investment for entry to the site

Smooth commencement of the project requires the closure of decisions, documentation and key supplies before the first works.

Therefore we confirm the detailed design documentation, approvals, schedule and building procedures before the teams arrive on site.

Six disciplines.
One coordinated design.

See where responsibilities meet. Detailed design resolves dependencies between architecture, building services and building requirements before trades start on site.

Office with glazed partitions and visible services below the ceiling
Architecture + HVAC + power + LAN + fire safety + BMS

Architecture sets the shared layout

Partitions, doors, glazing, ceilings and furniture are coordinated with services. We check dimensions, circulation, service access and material junctions.

Dependency
A new room cannot be just a partition outline; it needs coordinated services and equipment.
Coordination output
The agreed layout and details provide the basis for discipline coordination.

Ventilation and cooling for the actual demand

Equipment locations, routes, terminals, drains and maintenance access are checked against architecture and ceilings. Capacity is assessed against room functions.

Dependency
Higher occupancy or an enclosed room affects air distribution and system demand.
Coordination output
A coordinated HVAC solution with defined balancing and verification requirements.

Coordinated power and lighting

Power outlets, lighting, distribution boards and routes are coordinated with desks, rooms and joinery. Installation positions and discipline interfaces are checked.

Dependency
A luminaire, ventilation duct and ceiling component cannot occupy the same space.
Coordination output
Outlet and route layouts coordinated with the interior design.

Data infrastructure aligned with desks and AV/IT

Data outlets, cable routes, cabinets, equipment and user requirements are agreed before enclosure. Connections in furniture and meeting rooms are coordinated.

Dependency
Moving furniture or a display may change power and cabling requirements, not only the data outlet.
Coordination output
A coordinated data scope and connection documentation.

Safety systems and the new office layout

Partition and ceiling changes are checked against devices, routes, zones and required approvals. Interfaces with building systems are reviewed.

Dependency
A layout change may affect detectors, sprinklers, voice alarm or other in-scope systems.
Coordination output
A project-specific design and agreed scope of changes.

Controls and building integration

Control dependencies, integration scope and building-manager requirements are defined before commissioning. Points and devices are coordinated across disciplines.

Dependency
A new or relocated device may require control changes and agreed involvement of the building service team.
Coordination output
A confirmed integration scope and functional checks.
06 / 12Full delivery scope

Eight workstreams. One coordinated delivery

Walls, ceilings, building services, lighting and equipment cannot be planned as independent packages.

We combine all scopes into a single schedule, assigning responsibility, control points and the required outcome for acceptance.

Why do we combine trades into one scope?

Construction and installation works are not independent packages. Changing a wall affects the ceiling, lighting, HVAC, fire protection systems, teletechnics and equipment. That is why Ecoffices coordinates trades, scheduling, quality control and inspections under one responsibility.

07 / 12Logistics in an office building

Work logistics in an occupied office building

An operating office building imposes restrictions on deliveries, noise, building services shutdowns, vertical transport and waste removal.

We tailor the work plan to the building’s regulations and tenants’ work rhythm to minimise the impact of the delivery on the building’s operation.

Sample plan to be agreed with the building manager. Specific hours are derived from the building’s regulations.

Operating office building

The general contractor adapts works, deliveries, waste and tests to the building’s regulations and user traffic.

Office delivery logistics planOffice working hours: 08:00–18:00

Empty space

An empty space offers greater construction flexibility, but procedures, deliveries and inspections of the entire building still apply.

Office delivery logistics planOffice working hours: 08:00–18:00
standard windowconditionally possible

Non‑intrusive works agreed with the building – in accordance with the regulations.

How do we agree on deliveries and access to space?

The delivery schedule is coordinated with user traffic, the building’s regulations and the building manager’s procedures.

The general contractor coordinates large deliveries with the building manager to avoid blocking the unloading zone, communication corridors or the service elevator during office delivery.

08 / 12Quality, testing and handover

Quality control, inspections and handover of the office

Final quality is achieved throughout the entire delivery, not just at acceptance.

We check concealed works, materials, delivery and building services operation, then close defects and compile as-built documentation.

09 / 12Dependency matrix

Who needs what for delivery to keep moving?

Each row represents one delivery stage. Read from left to right: client decisions, design information and building requirements are inputs to Ecoffices’ work. The final column shows the output that unlocks the next stage.

Ecoffices leads the process. The other parties provide the decisions, information or approvals required at the right moment.

11 / 12Questions before the start

What to confirm before the start of work?

Before starting the project, you must confirm the entry point, completeness of documentation, the building’s technical conditions, and the boundaries of responsibility. The answers below clarify the issues that most often affect cost, schedule, and the way work is carried out.

Can you develop a concept prepared by another studio?

Yes. We analyse the concept’s assumptions and the space conditions, then prepare the detailed design documentation and coordinate trades. Based on this, we carry out general contracting of the office.

We deliver projects using detailed design documentation prepared by Ecoffices as part of our Design & Build process. We do not take on construction-only contracts based on detailed design documentation prepared by others, or stand-alone individual works.

The detailed design documentation and delivery remain in one Design & Build process.
At what stage is it worth engaging Ecoffices?

It is best when you are defining needs, selecting a space, or have an interior concept. Together we set the project scope, budget, and delivery conditions.

Early integration of design and construction facilitates decision-making.
What does general contracting of an office space include?

Demolition, construction works, glazing, ceilings, floors, HVAC, electrical, telecommunications, fire protection, built‑ins, furnishings, testing, and inspections.

All trades are managed within a single schedule and we deliver a complete result.
How does general contracting relate to refurbishment or modernisation of an office?

Refurbishment restores the standard of the existing office. Modernisation adapts the current team’s office to new functions, and adaptation prepares the space after the previous tenant for a new company. In every case we combine Ecoffices’ diagnosis and design with coordination, delivery, and inspections.

The same responsibility links design decisions with their delivery.
How is an office delivery offer prepared?

We analyse the design, material standard, building manager’s guidelines, schedule, and existing condition. If necessary, we conduct a local vision, uncovering, and coordination of missing solutions.

The price only makes sense when each party understands the same scope and boundaries of responsibility.
Can work be carried out in a functioning office or office building?

The possibility and working hours are agreed with the client and building manager. Bulk deliveries, noisy works, waste transport, and installation testing are scheduled within agreed windows.

The schedule takes into account users and the building’s actual procedures.
How are changes and additional works accounted for?

Each change is described, priced, and assessed for its impact on the schedule before it is executed.

After acceptance we update the scope, budget and schedule — before ordering material or starting the changed work.
What does the client receive upon final handover of the office?

A finished space, a closed list of defects and the required package of records, measurements, as-built documentation, instructions, material cards and warranties.

The handover of the office initiates the warranty period.
