Instruction: How to Hand Over a Completed Project to a Contractor

Short answer: Give a contractor one coherent package: a scaled plan, zones, planting, utility drawings, materials, dimensions, and a reviewable PDF. Small differences matter: a 1 m path instead of 1.2 m over 100 m changes paving area by 20 m², so record dimensions and set-outs precisely.

What does a contractor need to work?

To perform work efficiently, a contractor needs a comprehensive package of documents that provides a complete understanding of the future site. This package typically includes:

• Master plan of the site: A general drawing showing the location of all main elements — buildings, paths, recreation areas, water features, utility lines. It should include tie-ins to existing structures or site boundaries with precise dimensions.
• Zoning plan: Detailing functional zones (children's playground, BBQ area, vegetable garden, etc.) with their boundaries and purpose. This helps the contractor understand the logic of the space.
• Planting plan (dendroplan) and plant list: A scheme for planting all greenery, specifying species, varieties, sizes, and quantities. The list should include Latin and common names, as well as the required sizes of seedlings.
• Engineering utility plans: Plans for irrigation, lighting, drainage, and storm sewer systems, indicating routes, equipment installation locations, and connection points. For example, a correct drainage slope of 2-3 cm per linear meter is critical for water diversion.
• Setting-out drawings: Detailed drawings for complex elements (retaining walls, terraces, water features) specifying heights, materials, and structural solutions.
• Visualizations (3D models, collages): Images that help the contractor and you better envision the final result. Although not technical documents, they are indispensable for understanding the aesthetics and style.
• Material specifications: A list of all materials used (tiles, stone, wood, decorative elements) with their types, quantities, and suppliers, if necessary.

Choosing file formats: what does it depend on?

The format for project handover depends on the complexity of the work and the contractor's qualifications. Choose the most suitable ones to ensure maximum clarity:

• PDF: The most universal format. Ideal for general plans, planting plans, lists, and visualizations. Easily viewable on any device and guarantees the preservation of all fonts and scales. Most contractors prefer to receive drawings in PDF for printing and on-site review.
• DWG/DXF: Formats for working in CAD programs (e.g., AutoCAD). Necessary if the contractor will make changes, create working drawings, or use data for geodesic surveys. These files contain precise vector data and scales, which is critical for engineering solutions. However, if you are unsure that the contractor is proficient in such programs, it's better to stick to PDF.
• Images (JPG/PNG): Suitable for conceptual sketches, reference photos, and visualizations. They do not contain precise dimensions but perfectly convey the mood and overall design idea.
• Spreadsheets (XLSX, CSV): Used for material lists, estimates, plant lists. They allow for easy editing and volume calculation, which is very convenient for preparing commercial proposals and budget control.

Project detail: key to accuracy and budget

Insufficient project detail is one of the most common causes of problems during the implementation phase. The more precise and detailed your project, the fewer questions the contractor will have, and the fewer unforeseen expenses there will be. For example, a path 1 meter wide or 1.2 meters wide might seem like an insignificant difference, but over 100 meters in length, this is an additional 20 square meters of paving and base, which significantly impacts the budget. The same applies to heights: a 20 cm difference in planning a terrace or retaining wall requires recalculating the volume of soil, the number of steps, and drainage solutions.

It is important to specify:

• Precise dimensions and tie-ins: All objects on the site must have clear dimensions and be tied to existing objects or a coordinate grid. For example, the distance from the corner of the house to the start of the path is 3 meters 50 centimeters, not “approximately 3 meters.”
• Elevation marks: For terraces, retaining walls, water features, and drainage systems, absolute or relative elevation marks must be indicated. This will help avoid problems with drainage and level differences.
• Material specifications: Not just “tiles,” but “vibrated concrete paving slabs, grey, 40x40 cm, 6 cm thick.” For plants — not “bush,” but “Juniperus sabina ‘Tamariscifolia’, 30-40 cm height, C3 container.”
• Construction details: For complex elements (gazebos, pergolas, waterfalls), it is desirable to have drawings with sections and connection details. This will eliminate ambiguity and ensure the reliability of the structures.

Common mistakes when handing over a project

Even a well-thought-out project can encounter difficulties if it is not handed over correctly. Here are some common mistakes:

• Incomplete documentation: Handing over only a general plan without details, a planting plan, or engineering schemes. The contractor will be forced to guess or request missing data, which slows down work and can lead to errors. For example, the absence of an irrigation plan often leads to chaotic hose placement or inefficient water use.
• Lack of explanations for drawings: Even the most detailed drawings may not be fully understood without verbal or written comments. Be sure to discuss all contentious points and main ideas with the contractor. A typical mistake: pouring a foundation without considering the slope for future drainage, which then has to be redone.
• Ignoring the budget during the design phase: Creating a project without regard for real financial capabilities. This leads to the completed project being too expensive to implement, requiring simplification or rework. You can read more about this in the article “5 mistakes that drain your budget without results”.
• Project changes after work begins: Making significant revisions when part of the work has already been completed. This almost always leads to increased costs and delays. For example, deciding to change the height of a terrace by 20 cm after the base has already been laid will require dismantling, backfilling, new leveling, and re-laying.
• Uncoordinated deadlines: Lack of a clear work schedule, which complicates control and planning of material deliveries.

How to prepare a project for different types of contractors?

Project preparation may vary slightly depending on the contractor's specialization:

• For landscape works (plantings, lawns, water features): Emphasis on the planting plan with a plant list, a landscaping plan with paths and small architectural forms, and irrigation schemes. Visualizations will be especially useful for understanding the aesthetics.
• For construction works (foundations, retaining walls, terraces, gazebos): Master plan with precise tie-ins, setting-out drawings, sections, connection details, and specifications for construction materials. Engineering accuracy is crucial here.
• For engineering systems (lighting, drainage, automatic irrigation): Detailed schemes indicating routes, equipment installation locations, pipe diameters, types of luminaires, and sensors. Tie-ins to buildings and other site elements are mandatory.

Always hold a meeting with each contractor to discuss their part of the project to ensure a complete understanding of the tasks. This meeting should allow 2-3 days for reviewing documentation, not just a couple of hours.

Project handover checklist

Before handing over the project to the contractor, check yourself against this list:

1. Are all drawings ready and up-to-date? Do they include all necessary plans (master plan, planting plan, zoning, utility networks)?
2. Are there lists and specifications? Are lists of plants, materials, and equipment prepared with quantities and characteristics?
3. Does the project align with the budget? Have you discussed a preliminary estimate with the designer? Are real costs accounted for?
4. Are visualizations created? Do they help understand the overall look and feel?
5. Are all dimensions and heights precisely indicated? Are there tie-ins to existing objects?
6. Are site specificities considered? Relief, existing trees, utilities.
7. Are work completion deadlines agreed upon? Is there an overall schedule?
8. Has a briefing been conducted? Have you discussed all details with the contractor and answered their questions? Remember, dialogue is key to success.

How to plan and export a project in FormSpace

FormSpace offers intuitive tools for creating a detailed landscape project that you can effectively hand over to your contractor. Start with module 1.0 “Site Plan”, where you can draw the contour of your site, add existing structures, and set precise dimensions. In modules 1.1 “Zones” and 1.2 “Objects”, you can meticulously work out functional zones (e.g., a 15 m² recreation area with a barbecue and sofa) and arrange landscaping elements — paths 1.2 meters wide, terraces, water features, gazebos with precise dimensions and tie-ins. For more general concepts and ideas, you can use module 2.1 “AI Concept”, which helps quickly generate zoning options, and then refine them manually.

When the project is ready, you can use the built-in export functions. FormSpace allows you to export your plan in PDF format, which includes all layers: site contours, structures, zoning, objects, and text notes. This is an ideal option for handing over to a contractor, as PDF preserves scales and allows for easy printing of drawings. For more visual presentations, especially in the early stages, you can use module 3.1 “Design by Photo” to get photorealistic visualizations. These images can be attached to the technical documentation as JPGs so that the contractor better understands the desired aesthetic result. Thus, FormSpace becomes a central tool for creating and preparing all necessary documentation, ensuring a high level of detail and accuracy, which is critically important for successful interaction with implementers.

FAQ

What if the contractor doesn't understand the drawings?

If the contractor has difficulty understanding your drawings, it's a signal for further clarification. Organize a personal meeting on site, go through each element of the plan, explain the logic of zoning and tie-ins. Use visualizations and reference photos for a better understanding of aesthetic tasks. Perhaps it's worth simplifying some graphic elements or adding more textual explanations directly on the drawings.

Which format is best for a small project?

For small projects, such as arranging a single zone or planting a few plants, the PDF format will be the most convenient and sufficient. It is easily viewable and printable, preserving all scales and details. Additionally, you can attach a couple of high-quality photos or sketches in JPG to convey the mood and overall idea. Avoid complex CAD formats if there is no urgent need for them, so as not to complicate the process.

Should every sheet of the project be signed?

Yes, it is highly recommended to sign every sheet of the project. This not only gives the document official status but also helps avoid confusion with versions. Indicate the sheet number, total number of sheets, date of creation or last revision, and your initials or signature. This is especially important for large projects where documentation can consist of dozens of pages.

Can the project be changed after work begins?

Changing the project after work begins is highly undesirable and entails additional costs and delays. If changes are still necessary, they should be officially documented, incorporated into the drawings, and agreed upon with the contractor, fixing new deadlines and costs. Remember that any change, even a minor one, can affect the entire chain of work; for example, changing the location of a path by 0.5 meters may require replanning the entire irrigation system.

What if the contractor asks for CAD files and I don't have them?

If the contractor requests CAD files and you don't have them, explain that the project was created in another format (e.g., PDF). Offer to use the PDF as the primary document for work and suggest that they digitize or convert the necessary data into CAD format themselves if it is critical for their work. Discuss what specific data they need in CAD; perhaps a few key drawings will suffice. You could also offer to pay for the services of a designer who can convert the files if you cannot do it yourself.

How to ensure the contractor follows the plan?

Regular oversight is the best way to ensure the contractor follows the plan. Conduct site inspections at key moments of work, compare the actual location of objects with the drawings, and check the materials used and the quality of execution. Ask questions if you see deviations. It is important to establish a trusting relationship while strictly adhering to the project documentation. Photo documentation of work stages can also be useful.

What to do if plants are out of stock?

If some plants specified in the planting plan are out of stock, don't panic. Discuss the possibility of substitution with the contractor in advance. An experienced specialist can suggest similar species or varieties that match in size, shape, color, and growing conditions. It is important that the substitution is agreed upon with you and does not violate the overall design concept. It's best to have several alternative plant options in case the primary ones are unavailable.

Handing over a project to a contractor is not just about giving them a folder of documents; it's an important stage of interaction that requires attention to detail and clear communication. The more thoroughly you prepare the project, using tools like FormSpace, and the more detailed you explain your expectations, the higher the chances of successful and timely realization of your dream landscape. Do not hesitate to ask questions and clarify all nuances to avoid misunderstandings and costly mistakes at every stage of the work.
