1 General Scope

The project includes the rehabilitation of approximately 40 linear meters of existing timber dock (superstructure only, retaining piles) and the construction of a 15-meter dock extension with complete new structure (piles, beams, bracing, decking, and hardware). Works shall be executed according to approved drawings, ensuring marine durability and compatibility with existing conditions.

2 Timber Piles (New Section)

Provide and install pressure-treated timber piles, diameter 30 cm, length as required, driven to firm bearing. Timber shall be CCA-treated Southern Pine or equivalent hardwood, AWPA Class UC5C (marine use), with minimum retention 0.96 kg/m³.

Pile heads shall be capped with 6 mm galvanized steel plates and protected with epoxy sealant. Piles shall be installed vertically, aligned, and cut to final elevation. Contractor shall record pile-driving data.

3 Pile Head Connectors Supply and install galvanized or stainless-steel pile head brackets and cap plates, ASTM A36, 6 mm thickness, with through-bolts (Ø19 mm min.) and washers. All exposed steel surfaces shall be hot-dip galvanized or coated with marine-grade epoxy and polyurethane paint.

4 Transverse Beams (Joists) Install 2"x12"x6' transverse timber beams, CCA-treated pine, retention 0.60 kg/m³. Beams shall be anchored to longitudinal members with galvanized steel plates and bolts. Ends sealed with epoxy resin. Ensure correct alignment and spacing per design drawings.

Longitudinal Beams (Main Load Beams)

Install 2"x12"x10' longitudinal timber beams, forming main dock girders. All beams to be pressure-treated, straight, and defect-free. Beams shall be joined with overlapping stainless-steel angles and double through-bolts. Apply marine epoxy coating on all contact surfaces.

6 Cross Bracing Provide and install 2"x8" diagonal timber braces (8' and 10' lengths) between pile rows for lateral stability. Braces shall be CCA-treated and fastened with galvanized clamps and bolts. Ensure tight fit and full contact at joints; no gaps >3 mm.

7 Decking Boards (Timber Option) Install 2"x6"x6' decking planks, pressure-treated pine, CCA 0.60 kg/m³, pre-coated with marine-grade epoxy. Boards shall be installed with 5–8 mm expansion gaps and fixed using stainless steel screws or galvanized bolts. Apply non-slip finish and seal all cut edges.

8 Fasteners and Connection Kits Provide all hardware, bolts, nuts, washers, plates, and clamps required for assembly. Bolts: Ø19 mm min., ASTM A307 galvanized or AISI 316 stainless. All kits shall include washers and locknuts. Contractor to verify quantities per drawing. All hardware to meet ASTM A153/A123 galvanizing standards.

9 Structural Angles and Plates Install 2½"x¼" stainless steel or galvanized angles for central joints and beam intersections. Material: ASTM A36 or AISI 316, thickness 6 mm. All drilling and edges shall be protected with zinc-rich primer and epoxy topcoat.

10 Epoxy and Protective Coatings All exposed timber ends shall be sealed with marine epoxy resin. All metal surfaces shall receive a two-coat system: (1) zinc-rich epoxy primer (75 µm) and (2) aliphatic polyurethane topcoat (75 µm), total DFT ≥150 µm. All coatings shall be suitable for high-salinity marine environments.

Pile Bracing and Stability Enhancements (Existing Dock)
