SynC · Topic
These are the standards in the SynC Standards library that cover Civil. Each one is a complete, plain-language specification: the scope it applies to, the requirements that govern it, and a structured equipment datasheet listing the values a project has to decide — ratings, materials, setpoints, and the standards each is verified against. All of it is free to read without an account and published under CC BY-SA 4.0.
A standard usually carries several topics, so most of the entries below also appear under neighbouring subjects. The topics each one carries are listed on its own page.
Aggregate base course (ABC) for commercial, institutional, and industrial projects covering the placement, compaction, and quality control of crushed stone or processed graded aggregate used as the structural sub-base or base course beneath flexible (asphalt) and rigid (concrete) pavements, slabs-on-grade, building floor systems, exterior hardscape, equipment pads, and similar site improvements. Covers material classification and gradation, subgrade acceptance, geotextile separation where soft subgrades are encountered, lift placement, moisture conditioning, compaction, proof rolling, surface tolerances, and field testing. Intended to be read alongside the geotechnical investigation report, the civil grading drawings, and the structural or pavement section details, all of which govern design-specific values such as base thickness, target density, and material class.
Hot-mix asphalt (HMA) flexible pavement for commercial, institutional, and industrial site work, including parking lots, drive lanes, loading and service areas, fire lanes, and private site roadways. Covers surface (wearing) courses, intermediate (binder) courses, and asphalt base courses; prime and tack coats; performance-graded (PG) binder selection; Superpave and Marshall mix design and volumetric acceptance; reclaimed asphalt pavement (RAP) content; placement temperature and weather limits; lift thickness; in-place density and joint construction; and field testing for density, thickness, smoothness, asphalt content, and air voids. Intended to be read alongside the civil grading and paving drawings and the geotechnical report, which govern the design pavement section, course thicknesses, limits, grades, and drainage.
Earthwork for commercial, institutional, and industrial building projects covering site clearing and demolition, rough grading, mass excavation, structural excavation for foundations and slabs, trench excavation for utilities, classification of in-situ and imported materials, structural fill and backfill placement, compaction and moisture conditioning, subgrade preparation, dewatering, temporary excavation support and shoring, and erosion and sediment control. Intended to be read alongside the geotechnical investigation report and the civil grading drawings, both of which govern design-specific values throughout this standard.
Site perimeter, security, and screening fencing and the gates in it, for commercial, institutional, and industrial projects. Covers chain-link fence fabric, framework, rails, tension wire and fittings; ornamental tubular picket fence in galvanized steel, non-galvanized steel, and aluminum; welded wire mesh fence; barbed wire and barbed tape toppings; screening and privacy infill; posts, concrete footings, and alternative post-setting methods; swing, horizontal slide, vertical lift, and vertical pivot gates; pedestrian gates including those on an accessible route; automated vehicular gate operators listed to UL 325; gate construction to ASTM F2200; entrapment protection; gate locking and access-control rough-in; grounding and bonding; and fences that serve as a swimming pool or spa barrier.
Exterior underground wet and dry site utilities for commercial, institutional, and industrial building projects, beginning 5 feet outside the building footprint and extending to the point of connection at the public main, meter, or utility owner's facility. Covers the site domestic and fire water service and on-site water distribution (ductile iron and PVC pressure pipe, valves, hydrants, service fittings, thrust restraint), the site sanitary sewer (gravity collection mains and laterals, and pressurized force mains and low-pressure sewer), and the underground dry-utility infrastructure for electrical and telecommunications service (direct-buried and concrete-encased duct banks, conduit, and manholes/handholes). Also covers the common trenching, bedding, embedment, backfill, separation, tracer-wire and marking-tape locating, pressure and leakage testing, deflection and air testing, and water-main disinfection that apply across these systems.
Gravity storm sewer collection and conveyance on the site, for commercial, institutional, industrial, and multi-family projects. Covers storm sewer mains, laterals, and fittings in reinforced concrete, corrugated thermoplastic, solid-wall and profile-wall PVC, corrugated metal, and ductile iron; catch basins, curb and grate inlets, area drains, manholes, and junction structures; frames, grates, and covers; trench excavation, pipe embedment, and backfill within the pipe zone; outfall end treatments and scour protection; connection to an existing or municipal storm system; and the leakage, deflection, and video acceptance testing of the completed system.
