1. Specification (bill of materials)
The basis is a bill of materials linked to the project sections. At a minimum: item name, GOST/TU, unit of measure, volume, the required delivery date, the drawing or connection, and the person responsible for acceptance. Without a bill of materials, purchasing turns into a string of urgent add-on orders with a 15–25% overpayment.
2. Delivery schedule
Tied to the network construction schedule. A delivery arrives 3–5 days before the work front starts — not earlier (the storage gets cluttered), not later (the crew sits idle). For long-lead items (non-standard fasteners, imported hardware) — a buffer of up to 30 days.
3. On-site storage
The storage area must be included in the construction organization plan. At a minimum: a 6×9 m canopy for fasteners and dry mixes, a separate zone for paints and coatings with temperature control, and an area for non-combustible materials. Without storage, 30% of materials are lost or rejected.
4. Document flow
For every delivery: a UPD (universal transfer document), a VAT invoice, an acceptance report covering quantity and quality, a batch passport, and a certificate of conformity. The incoming inspection log is kept and signed by the site superintendent. For tender projects — copies in the project’s shared folder.
5. Buffer
Allow a 5–10% reserve by volume for consumable items (fasteners, mixes, consumables). For critical connections — a 100% reserve until acceptance (anchors, chemical compounds, specialty fasteners). It is cheaper to transport an extra pallet than to stop for 3 days waiting for an add-on order.
