How to Compare Network Installation Bids:
level the scope before you read a single price.
A seven-step bid-leveling method and a weighted scoring matrix, published by a contractor that both writes and answers these bids. The low bid wins on a leveled field — or it doesn't win at all.
To compare network installation bids, level them before you price them: normalize every bid to one scope line by line, price each bid's exclusions back in, convert lump sums to per-drop and per-device unit prices, then score with a weighted matrix where price carries about 20% of the total. Unleveled, the cheapest number usually hides the most expensive project.
SRS Networks is a nationwide IT infrastructure deployment partner headquartered in South San Francisco, California, deploying network infrastructure for multi-site enterprises and channel partners across all 48 contiguous states since 1996. The method below is the same framework SRS prices its own work against — share the scoring matrix with your bidders and every response you receive gets more honest.
The seven-step bid-leveling method
Leveling means making the bids answer the same question. Price is step seven, not step one.
1. Normalize scope line by line
Put every bid against the same drop counts, pathway scope, rack and ladder-rack scope, and fire-stopping penetration counts. Two bids that differ by 40 drops are not two prices for one project — they are two projects.
2. Price the exclusions
List what each bid excludes, then price those exclusions at the bidder's own unit rates. “Patch cords by others” and “fire-stopping by others” are line items you will pay someone for — put them back in the number before comparing.
3. Pin the certification deliverable
Every bid must commit to the same test standard — Fluke DSX permanent-link certification with a PDF report per drop, plus as-builts and a labeling schedule. A bid without a named standard is a bid for uncertified cable.
4. Convert lump sums to unit prices
Divide the leveled price into per-drop, per-AP, and per-camera units. Unit prices expose which bidder padded the small site and starved the big one — and they become your change-order protection after award.
5. Verify the labor model
Ask who is standing in the building: W-2 employees, subcontractors under agreement with audited COIs, or a broker's marketplace techs. The answer predicts documentation quality and no-show rates better than any reference call.
6. Score schedule realism
Divide claimed crew-days by site count and compare across the pack. A schedule 30-40% faster than every competing bid is not efficiency — it is a mobilization promise the bidder has not priced.
7. Run the matrix, then interview two
Score the leveled bids with the weighted matrix below and bring the top two in for a scope walk. The interview is where a padded bid unravels — ask each to defend their unit prices and their schedule math.
The weighted scoring matrix
Score each leveled bid 1-5 per row, multiply by the weight, and sum. Most buyers weight price at 100% without saying so — this matrix caps it at 20% and makes the other 80% visible.
| Criterion | Weight | What a 5/5 looks like |
|---|---|---|
| Leveled price | 20% | Only after scope is normalized and exclusions are priced back in |
| Scope completeness | 20% | Drop counts, pathway, racks, fire-stopping, grounding all addressed |
| Schedule realism | 15% | Crew-days per site in line with the pack; mobilization terms stated |
| Certification & deliverables | 15% | Named test standard, per-drop reports, as-builts, labeling schedule |
| Labor model | 10% | W-2 leads vs broker labor; named supervision; sub agreements disclosed |
| Insurance & COI compliance | 10% | COI provided with the bid, limits meeting site requirements |
| Change-order unit pricing | 10% | Adds priced per unit in the bid, not negotiated after award |
Pair the matrix with the 42-item RFP checklist so the bids you receive are scoreable in the first place, or start from the free IT RFP template.
Why the low bid loses money
A national infrastructure GC once tried to split our deployment crew into two staggered shifts on a 52-drop, 33-camera multi-building project — the premise was dodging overtime by rotating crews. We counter-proposed a concentrated Thursday-Friday extended shift with a crew of five to six and two to three simultaneous lifts. Their schedule would have cost the client 30% more in coordination overhead — shift handoffs, repeat tool moves, doubled site supervision — than the overtime they were trying to avoid. The cheaper-looking plan was the expensive one.
That pattern is the low bid in miniature. The number on page one is real; the costs it excludes are also real. Revisit truck rolls run $450-$950 each. Program management runs 8-12% of program cost whether the bid names it or not. A prudent budget carries 10-15% contingency. When a bid is silent on those, the money has not disappeared — it has moved into your change-order log.
Channel partners think they are buying hands and trucks. What they are actually buying is the compliance chain — the COI audit that keeps their client's GC from issuing a stop-work order. We audit every sub's COI before dispatch, at roughly $40 a site, because the incident it prevents costs $5K-$40K. On residential or small-commercial work where nobody enforces vendor COIs, that overhead does not pay back — which is exactly why bids that skip it look cheaper.
Seven red flags that predict change orders
Each of these is visible in the bid document, before award.
No unit pricing for adds
Every mid-project add gets priced from scratch, with no competitive pressure. Change-order markup lands at 2-3x the bid rate.
Vague exclusions (“by others”)
The gap between two bids' exclusion lists is where the real price hides. Unpriced exclusions come back as change orders in week three.
No named certification standard
“Tested and verified” without a standard means a toner and a continuity check. You get cable, not a certified plant — and no warranty registration.
Schedule far faster than the pack
A bid 30-40% quicker than every competitor is priced to win, not to execute. Expect thin crews, slipped mobilization, or both.
COI “available upon award”
A failed COI check on an enforced jobsite is a multi-day stop-work order — in our experience a $5K-$40K margin hit. Collect the certificate with the bid, not after it.
Lump sum only on multi-site work
Without a per-site breakdown, a bidder can shift cost between sites and hide where the number is soft. Multi-site bids get leveled per site or not at all.
No named project manager
If the bid carries no PM name and no PM line, coordination lands on you. Program management is real scope — it runs 8-12% of program cost when priced honestly.
When you don't need bid leveling — or SRS
A single site under roughly 25 drops does not need a scoring matrix. A local low-voltage shop will beat a national bench on price and drive time at that scale — collect two references and a COI and hire them. Bid leveling pays for itself when the project spans multiple sites, multiple bidders, or six figures — the scale where a 10% scope gap is real money. SRS's own economic floor is multi-site work; if your project is one office, we are not your cheapest option and will say so when you call.
Straight answers on comparing bids
Leveling means adjusting every bid to answer the same question before comparing prices: identical drop counts, identical pathway and rack scope, identical certification deliverables, with each bid's exclusions priced back in at its own rates. Once the scopes match, the price column finally means something. Comparing unleveled bids rewards whichever vendor excluded the most.
Because the missing cost is real even when it is not on page one. Revisit truck rolls run $450-$950 each, program management runs 8-12% of program cost, and a prudent budget carries 10-15% contingency. A bid that is silent on those items has moved them into your change-order log, where they get priced without competitive pressure.
Seven criteria cover it: leveled price (20%), scope completeness (20%), schedule realism (15%), certification and deliverables (15%), labor model (10%), insurance and COI compliance (10%), and change-order unit pricing (10%). Score each bid 1-5 per row, multiply by the weight, and sum. Capping price at 20% forces the other 80% of the project into view.
Three leveled bids is the working minimum; five is better on six-figure or multi-site work. Fewer than three gives you no read on where the market actually is. More than six adds evaluation time without changing the answer — and thins out the serious bidders, who can tell when an RFP has gone to twelve addresses.
The reliable ones are visible before award: no unit pricing for adds, vague by-others exclusions, no named certification standard, a schedule 30-40% faster than the rest of the pack, COI promised only after award, lump-sum-only pricing on multi-site work, and no named project manager. Each converts to a specific mid-project cost.
Yes — name the standard in the RFP so every bid prices it. Fluke DSX permanent-link certification with a PDF report per drop is the deliverable that makes a cabling plant testable, warrantable, and comparable across bidders. A bid that says tested and verified without naming a standard is quoting a continuity check, which is not the same product.
Rebuild them onto one baseline scope yourself, using each bidder's own unit rates to price whatever they excluded. If a bid does not carry unit rates, ask for them — a bidder that refuses to break out units is telling you how change orders will go after award. Only then read the price column.
A current COI showing general liability, workers' compensation, and auto limits that meet the site's requirements — submitted with the bid, not promised after award. On enforced jobsites a failed COI check is a multi-day stop-work order; in our experience the margin hit runs $5K-$40K. SRS audits every subcontractor COI before dispatch for exactly this reason.
Yes. SRS has deployed 500+ multi-site projects across 5,000+ sites in all 48 contiguous states since 1996, and responds to bids with unit prices, a named certification standard, a per-site breakdown, and a COI attached. We publish the scoring method because we win on leveled fields — and because unleveled bids are how buyers end up funding someone else's change orders.
