Maine#law#has#defined#the#practice#of#professional#engineering.#
"Practice#of#professional#engineering"#means#any#professional#service,#such#as#
consultation,#investigation,#evaluation,#planning,#design#or#responsible#supervision#
of#construction#in#connection#with#any#public#or#private#utilities,#structures,#
buildings,#machines,#equipment,#processes,#works#or#projects,#wherein#the#public#
welfare#or#the#safeguarding#of#life,#health#or#property#is#concerned#or#involved,#
when#such#professional#service#requires#the#application#of#engineering#principles#
and#data.#32#M.R.S.#§#1251(3)#
An#individual#that#designs#and#builds#their#own#home#and#applies#engineering#principles#is#
not#engaged#in#the#practice#of#professional#engineering#because#“the%public%welfare%or%the%
safeguarding%of%life,%health%or%property%is”%not%“concerned%or%involved.”#Had#that#same#person#
offered#to#design#and#build#their#neighbor’s#residence,#they#would#likely#be#in#violation#of#
the#practice#of#professional#engineering#since#the#“public%welfare%or%the%safeguarding%of%life,%
health%or%property%is%concerned%or%involved.”#
The#law#contains#numerous#exceptions#to#the#practice#of#professional#engineering#that#
allows#an#unlicensed#person#to#practice#professional#engineering#without#being#in#violation#
of#the#engineer#licensing#law.#For#example,#the#engagement#of#an#unlicensed#individual#
working#for#a#municipal#public#works#department#that#constructs#an#$80,000#bridge#would#
fall#under#an#exception#to#professional#engineering#pra ct ice.##
There#is#often#an#overlap#between#licensed#professions.#A#licensed#architect#that#designs#a#
50.5#million#dollar#high#school#would#be#practicing#professional#engineering#but#such#
practice#in#this#situation#is#permitted#for#licensed#architects#since#the#engineering#law#can#
not#prevent#the#practice#of#other#legally#recognized#professions.#
There#are#many#gray#areas#of#practice#that#are#the#basis#for#complaints#alleging#unlicensed#
practice#that#are#received#by#the#Board.#For#example,#persons#offering#home#inspection#
services#have#often#been#brought#to#the#attention#of# t he#Board.#In#such#cases,#the#Board#
must#determine#if#the#services#involve:#“professional%services%…%requir[ing]#the%application%of%
engineering%principles%and%data.”#If#the#home#inspection#is#confined#to#reporting#broken#
windows,#cracked#concrete,#mold,#water#leakage,#etc.#engineering#principles#and#data#were#
not#applied#and#the#home#inspector#would#not#be#practicing#professional#engineering.#
However,#if#the#home#inspector#reported#the#outside#bearing#wall#of#the#residence#would#
not#support#a#typical#Maine#snow#load,#engineering#principles#and#data#were#applied#and#
the#home#inspector#would#be#deemed#to#be#practicing#professional#engineering.#
Perhaps#surprisingly,#many#complaints#involving#unlicensed#practice#that#do#result#in#fines#
and#penalties#involve#licensed#professional#engineers#that#allowed#their#license#to#lapse#
inadvertently#while#continuing#to#engage#in#engineering#consulting#work.#The#professional#
engineer#that#sent#a#proposal#for#an#engineering#design#on#14#January#after#their#license#
lapsed#on#31#December#and#failed#to#renew#their#license#until#24#January#is#likely#guilty#of#
the#unlicensed#practice#of#professional#engineering.#
