TECHNICAL TASK
for the development of the electricity supply project and internal electrical networks
of a two-story residential building in the cottage settlement "Goodwill residence", village Pishchanka
1. General information about the object
1.1. The object is a two-story residential building with an approximate area of ~175 m² with a terrace in the cottage settlement "Goodwill residence", village Pishchanka.
1.2. An architectural and interior design project has been developed for the house (planning solutions, floor plans, ceiling plans, furniture and lighting placement) – attached in PDF and/or DWG format.
1.3. The design should be carried out taking into account the existing planning solutions, designed lighting scenarios, and the placement of furniture and sanitary appliances.
2. Subject and scope of work for the designer
2.1. Develop a working project for the electricity supply and internal electrical networks of the house, suitable for immediate installation work.
2.2. The project must include (but not be limited to):
- A scheme for the electricity supply of the house, taking into account existing or planned technical conditions from the distribution system operator (input, meter, panel, protection, accounting).
- Calculation of the required power of the house, consumer groups, and selection of cable cross-sections, circuit breakers, RCDs, etc.
- A plan for the placement of power socket groups throughout all rooms (2 floors) with reference to furniture and equipment according to the design project.
- A lighting plan inside the house: fixtures, switching groups, lighting scenarios, dimming (if necessary), taking into account already designated lighting points on ceiling plans.
- A plan for outdoor lighting of the adjacent territory: facade lighting, terrace lighting, entrance, paths, possible barbecue/courtyard area (the list of points can be clarified with the Customer during the process).
- A scheme and solutions for grounding and lightning protection of the house in accordance with current regulations.
- A scheme of electrical panels (main panel, floor/group panels) showing all lines, circuit breakers, RCDs, voltage control relays, surge protection, etc.
- Solutions for low-voltage networks (basic): internet, TV, intercom, video surveillance (minimum – routes and output points).
- A connection node for a backup power source (generator/inverter):
- develop a generator connection scheme;
- provide for switching between main power/reserve (automatic or manual transfer to reserve – to be agreed separately);
- determine which groups will be powered by the generator (critical loads).
3. Most important – material specification
3.1. The project must contain a detailed specification of all materials and equipment necessary for installation, including:
- cables/wires (type, cross-section, number of meters for each line or total for the group);
- circuit breakers, RCDs, differential circuit breakers (type, ratings, quantity);
- panel products (enclosures, DIN rails, busbars, accessories);
- sockets, switches, TV/internet sockets, terminals, boxes;
- fixtures (if specific models are included) or requirements for them (type, power, degree of protection);
- grounding and lightning protection materials;
- other consumables necessary for the complete installation of the system.
3.2. It is preferable that the specification be made in the form of a separate table (Excel/PDF), suitable for direct use in forming estimates and purchases.
4. Requirements for project documentation
4.1. Format of delivery:
- electronic format in PDF (for printing) and DWG/DXF (for the work of installers and adjustments);
- if necessary – a short explanatory note describing the accepted solutions and calculation data.
4.2. The drawings must necessarily reflect:
- floor plans with all sockets, switches, lighting fixtures, routes of main cable lines;
- schemes of panels (single-line and/or schematic);
- schemes for connecting the generator;
- schemes for grounding and lightning protection;
- an explication of rooms and load tables by groups.
4.3. Project solutions must comply with current DBN and PUE of Ukraine.
5. Input data from the Customer
The Customer provides:
- interior design project (plans, layouts, placement of furniture and lighting);
- information about existing/planned technical conditions for electricity supply (allocated power, connection scheme);
- wishes regarding equipment brands (if there are preferred manufacturers of circuit breakers, cables, fittings, etc.);
- a list of outdoor lighting zones that must be taken into account.
6. Requirements for the contractor
6.1. Experience in developing similar projects (private houses 150–300 m²) – preferably confirmed by examples.
6.2. Availability of permits/certificates for performing design work (if available – indicate in the commercial proposal).
6.3. Willingness to undergo a minimum of 1–2 rounds of adjustments after discussion with the Customer without significant changes in cost.
7. What we ask to indicate in the commercial proposal
- The total cost of project execution.
- The estimated time for completing the work from the moment of receiving all input data.
- The format of cooperation (online/onsite visits if necessary).
- The conditions for author supervision during installation (separately or included in the cost).
