Technology Specification Writing
Phrases such as “provide networking” or “pre-wire for AV” do not define comparable work. One bidder may include tested permanent links, managed switching, labels, and as-builts while another prices loose cable to approximate locations. Both can claim compliance with the same vague note. A proper technology specification defines required performance, products or a basis of design where appropriate, execution quality, testing, documentation, and objective acceptance criteria.
GGIS develops coordinated communications requirements in CSI Division 27 and electronic safety and security requirements in Division 28, with cross-references to affected architectural, electrical, and mechanical work. Current, edition-neutral references can include ANSI/TIA-568 for cabling performance, TIA-569 for pathways and spaces, TIA-606 for labeling and administration, and TIA-607 for bonding and grounding. Project applicability and adopted code requirements are verified rather than assumed.
What we deliver
- Project-specific CSI Division 27 communications and Division 28 electronic safety and security sections with coordinated scope boundaries
- Performance requirements for media, link capability, PoE demand, coverage, capacity, retention, interoperability, resilience, and maintainability
- Named products or basis-of-design selections where justified, paired with measurable substitution requirements and a deviation schedule
- Edition-neutral ANSI/TIA-568 cabling-performance and acceptance language tied to the project’s permanent-link or channel test basis
- TIA-569 pathway and space criteria for conduit, sleeves, pull access, fill, bend geometry, telecommunications rooms, and service clearances
- TIA-606 labeling and administration requirements coordinated across outlets, cables, panels, racks, drawings, and electronic records
- TIA-607 bonding and grounding coordination identifying interfaces and responsible trades without assigning unqualified electrical work
- Execution, testing, deficiency correction, documentation, training, account transfer, and final acceptance requirements
How we approach it
We begin with owner requirements, existing standards, system narratives, drawings, project delivery method, and the parties expected to operate the finished systems. Outcomes are stated before catalog numbers: link performance, wireless coverage method, recording behavior, control functions, usable capacity, maintainability, and expansion allowances. We identify what belongs in Division 27, Division 28, Division 01, drawings, or other trade sections so requirements are stated once and cross-referenced correctly. Referenced standards are written edition-neutrally where appropriate and checked against the governing code and project requirements instead of being copied into a generic standards list.
Each section addresses submittals, products, execution, quality control, testing, and closeout. Basis-of-design equipment is used only where it clarifies performance, compatibility, or owner standards, and substitutions must disclose dimensions, power, thermal load, protocols, licensing, cybersecurity, software, mounting, and integration effects. Cabling language coordinates ANSI/TIA-568 performance, TIA-569 pathways and spaces, TIA-606 administration, and TIA-607 bonding and grounding requirements without treating those standards as interchangeable. A comment matrix lets the owner, architect, engineers, IT, security, and builder resolve conflicts while preserving a visible decision trail.
Bid documents are checked against plans and schedules so outlet counts, identifiers, device locations, and responsibility boundaries agree. During procurement, GGIS supports submittal and substitution review against the actual specification rather than accepting a manufacturer name as proof of equivalence. Questions move through formal RFIs, and approved changes are incorporated by addendum, bulletin, or controlled revision. Construction observations cite the applicable paragraph and drawing reference, giving the GC an assignable issue. GGIS provides planning, programming, and testing support.
Acceptance language is written before bids are received. It identifies the test basis, required coverage, configuration, pass/fail limits, result format, corrective process, and evidence needed to close a deficiency. Where Tier 1 optical-loss testing is required, the specification defines the applicable method and acceptance basis while instrument provision and test delivery are arranged with the responsible contractor or qualified testing resource; it does not assume unverified in-house OLTS capability. Functional testing remains separate from cable acceptance. Final review reconciles reports, approved substitutions, as-builts, backups, asset data, account transfer, training, and warranty documents.
Frequently asked questions
Why are notes such as “provide networking” or “pre-wire for AV” inadequate?
They name an intent but not a deliverable. They omit topology, cable and pathway criteria, endpoint locations, products or performance, execution, labels, tests, records, and acceptance. Bidders must fill those gaps with their own assumptions, so prices cannot be compared fairly and omissions emerge during construction. A specification makes those assumptions explicit and coordinates them with drawings, schedules, and responsibility boundaries.
How do Division 27, Division 28, and the TIA standards fit together?
CSI Division 27 organizes communications work, while Division 28 organizes electronic safety and security work. The TIA references supply technical criteria within that project structure: ANSI/TIA-568 addresses cabling performance, TIA-569 pathways and spaces, TIA-606 administration and labeling, and TIA-607 bonding and grounding. Other interfaces may remain in Divisions 01, 23, 26, or architectural sections. We use current, edition-neutral language where appropriate and coordinate cross-references rather than duplicating obligations.
Can a basis of design allow competitive alternatives?
Yes, if equivalence is measurable. The section should state required performance, dimensions, mounting, interfaces, protocols, environmental ratings, power, management, support, and integration behavior, then require a side-by-side deviation schedule. Some platforms have proprietary drivers or ecosystem dependencies that make substitution consequential. Those effects should be priced and approved openly. The phrase “or equal” alone does not establish technical equality or protect fair bid comparison.
